ORIGINAL PAPEREvaluation of angiotensin I-converting enzyme (ACE)inhibitory activities of smooth hound (Mustelus mustelus )muscle protein hydrolysates generated by gastrointestinal proteases:identification of the most potent active peptideAli Bougatef •Rafik Balti •Naı¨ma Nedjar-Arroume •Rozenn Ravallec •Estelle Yaba Adje´•Nabil Souissi •Imen Lassoued •Didier Guillochon •Moncef NasriReceived:27January 2010/Revised:18February 2010/Accepted:27February 2010/Published online:18March 2010ÓSpringer-Verlag 2010Abstract In this study,smooth hound protein hydroly-sates (SHPHs),obtained by treatment with various gas-trointestinal proteases,were analyzed for their angiotensin I-converting enzyme (ACE)inhibitory activities.Protein hydrolysates were obtained by treatment with crude alka-line enzyme extract,low molecular weight (LMW)alkaline protease,trypsin-like protease and pepsin from Mustelus mustelus ,and bovine trypsin.All hydrolysates exhibited inhibitory activity toward ACE.Hydrolysate generated with alkaline protease extract displayed the highest ACE inhibitory activity,and the higher inhibition activity (82.6%at 2mg/mL)was obtained with a hydrolysis degree of 18.8%.This hydrolysate was then fractionated by size exclusion chromatography on a Sephadex G-25into five major fractions (P 1–P 5).ACE inhibitory activities of all fractions were assayed,and P 3was found to display a high ACE inhibitory activity (62.24%at 1mg/mL).P 3was then fractionated by reversed-phase high-performance liquid chromatography (RP-HPLC)and ten fractions of ACE inhibitors were found (F 1–F 10).Sub-fraction F 3showed the strongest ACE inhibitory activity,being able to suppress more than 60%of initial enzyme activity at a concentration of 100l g/mL.The amino acid sequence of peptide F 3was determined by ESI/MS and ESI–MS/MS as Ala-Gly-Ser,and the IC 50value for ACE inhibitory activity was0.13±0.03mg/mL.Further,purified peptide F 3main-tained inhibitory activity even after in vitro digestion with gastrointestinal proteases in order to demonstrate gastro-intestinal stability digestion to enable oral application.These results indicate that smooth hound protein hydroly-sate possesses potent antihypertensive activity.Keywords Smooth hound muscle ÁM.mustelus ÁIntestine crude extract ÁEnzymatic treatment ÁACE inhibitory activities ÁProtein hydrolysates AbbreviationsSHPH Smooth hound protein hydrolysate ACE Angiotensin-converting enzyme LMW Low molecular weight DH Degree of hydrolysisIntroductionHigh blood pressure has been considered a risk factor for developing cardiovascular diseases (arteriosclerosis,stroke and myocardial infarction)and end-stage renal disease [1].Angiotensin I-converting enzyme (ACE,dipeptidyl car-boxy peptidase,EC 3.4.15.1)plays an important physio-logical role in the regulation of blood pressure by virtue of the rennin angiotensin system [2,3].It is a multifunctional zinc-containing enzyme,located in different tissues.ACE converts the inactive decapeptide,angiotensin I to the potent vasopressor octapeptide,angiotensin II and inacti-vates bradykinin [2].Inhibition of ACE is considered to be a useful thera-peutic approach in the treatment of high blood pressure.A.Bougatef (&)ÁR.Balti ÁN.Souissi Ássoued ÁM.NasriLaboratoire de Ge´nie Enzymatique et de Microbiologie,Ecole Nationale d’Inge´nieurs de Sfax,BP ‘‘1173’’,3038Sfax,Tunisiae-mail:ali.bougatef79@N.Nedjar-Arroume ÁR.Ravallec ÁE.Y.Adje´ÁD.Guillochon Laboratoire de Proce´de ´s Biologiques,Ge ´nie Enzymatique et Microbien,IUT A Lille I,BP 179,59653Villeneuve d’Ascq Cedex,FranceEur Food Res Technol (2010)231:127–135DOI 10.1007/s00217-010-1260-4Several effective oral ACE inhibitors have been developed, namely,captopril,enalapril,and lisinopril and all are cur-rently used as clinical antihypertensive drugs[4].Although synthetic ACE inhibitors are effective as antihypertensive drugs,they cause adverse side effects such as coughing, allergic reactions,taste disturbances,and skin rashes. Therefore,research and development tofind safer,inno-vative,and economical ACE inhibitors is necessary for the prevention and remedy for hypertension.Structure–activity correlation among different peptide inhibitors of ACE indicates that binding to ACE is strongly influenced by the C-terminal tripeptide sequence of the substrate.ACE appears to prefer substrates or competitive inhibitors that mainly have hydrophobic (aromatic or branched side chains)amino acid residues at the three C-terminal positions.ACE inhibition studies with Trp,Tyr,Phe,or Pro residues were most effective in enhancing substrate binding[5].Nevertheless,the structure–activity relationship of ACE inhibitory peptides has not yet been established,and very different hypo-tensive sequences have been derived from a large num-ber of food proteins[6].It is postulated that the mechanism of ACE inhibition involves inhibitor inter-action with an anionic binding site that is distinct from the catalytic site.Since the discovery of ACE inhibitors in snake venom [7],several reports have been published on the ACE inhibitory activity of peptides from food proteins,like casein[8],rapeseed[9],mushroom[10],whey protein[11], porcine muscle[12],bovine skin gelatin[13],soybean [14],sake and sake lees[15],andfish proteins[16,17].Proteases such as pepsin,chymotrypsin,and trypsin are frequently used in hydrolysis to produce ACE inhibitory peptides[18–20].Microbial alkaline proteases are also utilized in the production of ACE inhibitors from food proteins such as sardine(Sardina pilchardus)[21]and rapeseed[9].However,there are a small number of reports on the use of digestive enzymes fromfish in the producing bioactive peptides[22,23].The smooth hound Mustelus mustelus is the most abundant hound shark in the Mediterranean Sea.It is found in the eastern Atlantic from the British Isles to South Africa,including the Mediterranean Sea.This species is found throughout the Tunisian coasts,including Sfax. Smooth hound is relatively important in thefish-catches of Tunisia and is utilized for human consumption. M.mustelus is generally available all year long,and the production was about192tons in2007.In a previous paper,we have shown that digestive pro-teases from smooth hound were very well suited for the generation of hydrolysates enriched in antioxidative pep-tides,from muscle protein of the same species[22].In the present study,we have attempted to isolate and identify inhibitory peptide from smooth hound muscle protein hydrolysate as powerful displaying ACE inhibitory. Materials and methodsSmooth hound sample preparationSmooth hound(M.mustelus)was purchased from thefish market of Sfax City,Tunisia.Muscle and internal organs (stomach and intestines)were separated,rinsed with cold distilled water,then immediately frozen and stored at -20°C until used.Enzymes and chemicalsAngiotensin I-converting enzyme(ACE)from rabbit lung and the ACE synthetic substrate hippuryl-L-histidyl-L-leu-cine(HHL)were purchased from Sigma Chemicals Co(St Louis,MO,USA).Acetonitrile was of HPLC grade. Sephadex G-25was purchased from Pharmacia(Uppsala, Sweden).Water was obtained from a Culligan system;the resistivity was approximately18M X.Other chemicals and reagents used were of analytical grade.The enzymes used for the production of protein hydrol-ysates were the following:pepsin from M.mustelus stomach [24];low molecular weight(LMW)alkaline protease[25], trypsin-like protease[26]and crude enzyme extract from M.mustelus intestines,and bovine trypsin(purchased from Sigma Chemical Co.(St.Louis,MO,USA)).Preparation of crude protease extract from smooth hound intestinesIntestines from M.mustelus(150g)were homogenized for 1min with300mL of extraction buffer(10mM Tris–HCl, pH8.0).The homogenate was centrifuged at8,500g for 30min at4°C.The pellet was discarded and the supernatant was collected and referred to as crude alkaline protease extract(Fig.1).Alkaline protease activity in the crude extract was measured by the method of Kembhavi et al.[27] using casein as a substrate.One unit of protease activity was defined as the amount of enzyme required to liberate1l g of tyrosine per min under the experimental conditions used. Pepsin,low molecular weight protease,and trypsin-like protease were purified as reported by Bougatef et al.[24–26]. Production of smooth hound muscle protein hydrolysates(SHPHs)using various proteasesThe production of protein hydrolysates was carried out as reported by Bougatef et al.[22].The scheme for the pro-duction of protein hydrolysates is given in Fig.1.The degree of hydrolysis(DH)was determined as reported by Adler-Nilsen[28].For the hydrolysate pro-duced by pepsin treatment,DH was determined as descri-bed by Hoyle and Merritt[29].Determination of the ACE inhibition activityThe ACE inhibition activity was assayed as reported by Nakamura et al.[30].For each assay,80l L of SHPH at different concentrations was added to200l L of5mM hippuryl-L-histidyl-L-leucine(HHL),and then pre-incu-bated for3min at37°C.SHPH and HHL were prepared in100mM borate buffer,pH8.3,containing300mM NaCl.The reaction was then initiated by adding20l L of 0.1U/mL ACE from rabbit lung prepared in the same buffer and incubated for30min at37°C.The enzyme reaction was stopped by the addition of250l L of0.1M HCl.The released hippuric acid(HA)was quantified by RP-HPLC on a Vydac C18column connected to a system composed of a Waters TM600automated gradient con-troller pump module,a WaterWisp717automatic sam-pling device,and a Waters996photodiode array detector. The sample was then eluted using an acetonitrile gradient from0to28%and from28to47%in0.1%trifluoro-acetic acid(TFA)(v/v)for50and20min,respectively. The elution profile was monitored at228nm.Spectral and chromatographic data were stored on a NEC lennium software was used to acquire,analyze,and plot chromatographic data.The average value from three determinations at each concen-tration was used to calculate the ACE inhibition rate as follows:ACE inhibitionð%Þ¼BÀABÀC!Â100where A is the absorbance of HA generated in the presence of ACE inhibitor component,B is the absorbance of HA generated without ACE inhibitors,and C is the absorbance of HA generated without ACE(corresponding to HHL autolysis in the course of enzymatic assay).The IC50value was defined as the concentration of hydrolysate(mg/mL)required to reduce the hippuric acid peak by50%(indicating50%inhibition of ACE).Fractionation of SHPH obtained by treatmentwith crude alkaline proteases by Sephadex G-25gelfiltrationThe freeze-dried hydrolysate(1g),with a DH of18.8%, was suspended in20mL of distilled water,then loaded onto a Sephadex G-25gelfiltration(5cm954cm),pre-equilibrated and eluted with distilled water.Fractions (5mL each)were collected at aflow rate of60mL/h,and the absorbance was measured at226nm.Fractionsassociated with each peak showing ACE inhibitory activity were pooled and freeze-dried.Reversed-phase high-performance liquid chromatography(RP-HPLC)The fraction P3from Sephadex G-25,which exhibited the highest ACE inhibitory activity,was further separated by RP-HPLC on a Vydac C18column(10mm9250mm) (Grace-Vydac,USA).The liquid chromatographic system consisted of a Waters600E automated gradient controller pump module,a Waters Wisp717automatic sampling device,and a Waters996photodiode array detector. Spectral and chromatographic data were stored on a NEC lennium software was used to plot,acquire,and analyze chromatographic data.The mobile phase was water/trifluoroacetic acid(1000:1,v/v) as eluent A and acetonitrile/trifluoroacetic acid(1000:1,v/v) as eluent B.Samples werefiltered through0.22l mfilters, and then applied on the C18column and eluted by eluent A for15min then with a linear gradient of acetonitrile in 45min.Theflow rate was1mL/min.Online UV absor-bance scans were performed between200and300nm at a rate of one spectrum per second with a resolution of 1.2nm.Chromatographic analyses were completed with Millennium software.Mass spectrometry analysisMS and MS/MS measurements were performed in positive ion mode using Electrospray ionization(ESI)and ESI/MS/ MS,respectively.ESI mass spectrometry was performed using a triple quadrupole instrument Applied Biosystems API3000(PE Sciex,Toronto,Canada).The system is controlled by the Analyst Software1.4,allowing the con-trol of the spectrometer,the analysis and the processing data.Interpretations of spectra MS–MS were made with the Bioanalyst software.The freeze-dried samples were dis-solved in a solvent acetonitrile/water(20/80v/v)contain-ing formic acid0.1%for the positive mode.The solution was injected(nebulized)uninterrupted,using a pump (Model22,Harward Apparatus,South Natick,USA)with a flow rate of5l L/min.The potential of ionization was of 5,000V in positive mode.At the time of the recording of the spectrum,30scans on average were added(MCA mode)for each spectrum.The gases used(nitrogen and air) were pure(up to99%)and produced by a compressor Jun-Air4000-40M and a nitrogen generator Whatman model 75-72(Whatman Inc,Haverhill,MA,USA).The poly-propylene glycol(PPG)was used for the calibration and the optimization of the machine.The peptide sequence was determined from the CID spectrum of the protonated ana-lyze[M?H]?by MS/MS experiments.Digestion stability studyThe stability of the ACE inhibitory activity of the purified peptide from fraction F3against gastrointestinal proteases was assessed in vitro.Samples(2mg/mL)were individu-ally incubated with pepsin(pH2.0),or trypsin(pH8.0)for 3h at37°C.In successive digestion test,the sample was first incubated with trypsin for3h,heat treated for5min in boiling water to inactivate the enzyme,and then incubated 3h at37°C with chymotrypsin.The reactions were then heated for5min in boiling water to terminate the reactions. The digests were used for measuring the ACE inhibitory activities.Determination of ACE inhibition patternTo clarify the inhibitory mechanism of the most potent peptide(Ala-Gly-Ser)on ACE,different concentrations of the ACE inhibitory peptide were added to each reaction mixture according to the method of Wu and Ding[31], with slight modifications.The enzyme activities were measured with different concentrations of the substrate (HHL).ACE inhibitory pattern in the presence of the inhibitor was determined with Lineweaver–Burk plot.Statistical analysisStatistical analyses were performed with Statgraphics ver.5.1,professional edition(Manugistics Corp.,USA)using ANOVA analysis.Differences were considered significant at p\0.05.Results and discussionProduction of SHPH using gastrointestinal proteasesThe hydrolysis of proteins,which is measured in terms of degree of hydrolysis(DH),is an important parameter in determining size dependent functional properties of protein hydrolysates preparations[32].DH affects the size and hence the amino acid composition of the peptides,which can affect the taste of protein hydrolysate by producing bitter peptides at high DH[32].Change in amino acid composition as affected by DH could also modulate the biological activity of the peptides formed during hydrolysis.ACE inhibitory peptides can be produced by solvent extraction,enzyme hydrolysis,and microbial fermentation of food proteins.The most common way to produce ACE inhibitory peptides is through enzymatic hydrolysis of food proteins.The specificity of the proteolytic enzyme and process conditions influence the peptide composition of hydrolysates and thus their ACE inhibitory activities[33].In the present study,intestine crude enzyme extract, LMW alkaline protease,trypsin-like protease and pepsin from smooth hound viscera,and bovine trypsin were used for the production of protein hydrolysates.The crude alkaline protease extract was most efficient,whereas pepsin was least efficient.After4h of hydrolysis,the DH reached about20.3,15.4,12.0,10.1,and9.2%with crude alkaline protease extract,LMW protease,trypsin-like protease, bovine trypsin,and pepsin,respectively[22].ACE inhibitory activities of SHPH obtainedwith various proteasesThe hydrolysates obtained after4-h incubation with gas-trointestinal proteases were then assayed for ACE inhibi-tory activity.All hydrolysates,at2mg/mL,showed ACE inhibitory activities at different level(data not shown).The highest ACE inhibitory activity(67.27%)was observed with intestinal crude enzyme hydrolysate followed byLMW protease hydrolysate(52.34%).Pepsin hydrolysate exhibited the lowest ACE inhibitory activity(45.12%).The IC50values for ACE inhibition of all hydrolysates varied between0.85and3.55mg/mL(Fig.2).The IC50 value of SHPH(0.85±0.02mg/mL)obtained with intestinal crude protease extract was lower than those of hydrolysates from oyster,scallop,codfish skin,and herring skin whose presented an IC50greater than10mg/mL[34], whereas it is higher than those from bonito(IC50= 0.029mg/mL)[35],salmon(IC50=0.038mg/mL)[36], and sardine(IC50=0.082mg/mL)[37].This can be attributed to the impact of the enzyme’s specificity which is a key factor influencing both the characteristics of hydrolysates and the nature and composition of peptides produced.Proteolysis can operate either sequentially, releasing one peptide at a time,or through the formation of intermediates that are further hydrolyzed to smaller pep-tides as proteolysis progresses,which is often termed‘‘the zipper mechanisms’’[38].Depending on the specificity of the enzyme,environmental conditions,protein source,and the extent of hydrolysis,a wide variety of peptides size will be generated.Resulting protein hydrolysate will possess peculiar properties according to the new peptides generated.These results indicated that the crude alkaline protease extract from M.mustelus intestines would be effective in producing ACE inhibitory peptides.Effect of the degree of hydrolysis on ACE inhibitory activityThe degree of hydrolysis is a measure of the extent of hydrolysis degradation of a protein,and it is the most widely used indicator for comparison among different protein hydrolysates.During hydrolysis,a wide variety of larger,medium than smaller peptides are generated, depending on enzyme specificity.In order to study the effect of the DH on the generation of ACE inhibitory activity,smooth hound muscle proteins were hydrolyzed by the crude protease extract from the intestines of M.mustelus,and the degree of hydrolysis and the ACE inhibition activity were determined.Figure3shows ACEinhibitory activity of released smooth hound peptides along the enzymatic hydrolysis.This profile shows clearly that hydrolysis was necessary in order to release ACE inhibi-tory peptides.However,undigested smooth hound muscle proteins (DH:0%)exhibited very low ACE inhibitory activity (about 1.5%at 2mg/mL).Further,Fig.3shows that the ACE inhibitory activity was correlated with the DH of hydrolysis.Higher ACE inhibition (p \0.05)activity (82.6%at 2mg/mL)was obtained with a DH of 18.8%(after 120min incubation).Further digestion up to a DH value of 18.8%resulted in a decrease in the ACE inhibitory activity.The obtained results clearly show that hydrolysis was required to release ACE inhibitory peptides from an inactive form within the sequence of smooth hound muscle proteins.Fractionation of the protein hydrolysate obtained by treatment with alkaline proteases from M.mustelus intestines by gel filtration G-25The hydrolysate,with a DH of 18.8%,obtained by treat-ment with crude alkaline protease extract,which displayed the highest ACE inhibitory activity,was then fractionated by gel filtration chromatography on a Sephadex G-25column.Five fractions were separated and designated asP 1–P 5(Fig.4a).Fractions were pooled,freeze-dried,and the inhibition against ACE was determined.All fractions displayed ACE inhibitory activity,as shown in Fig.4b.Fraction P 3exhibited the highest level of ACE inhibitory activity (62.24±2.21%at 1mg/mL)followed by fraction P 2(53.14±1.82%).The IC 50value of P 3was determined with logarithmic linearization [39]to be 0.33mg/mL.These results indi-cated that ACE inhibitory peptides are present in the pared with several reports on various protein hydrolysates,which showed IC 50for ACE inhibitory activities in the range of 0.18–246.70mg/mL [40,41],the SHPH had moderate ACE inhibitory activity.0,15 0,20 0,25 0,30501000,10 0,05 0,0 Table 1Hydrolysis conditions of smooth hound muscle proteins EnzymeSourceOptimum conditions Temperature (°C)pHCrude enzyme extract M.mustelus intestine

identification of F 3peptide The active fraction P 3,which displayed the highest level of ACE inhibitory activity,was further purified by RP-HPLC on a C 18column using a linear gradient of acetonitrile.As can be seen from the chromatographic profile at 214nm,given in Fig.5,at least ten major fractions (F 1–F 10)were present in fraction P 3.These fractions were collected,and their ACE inhibitory activities were determined.All frac-tions showed ACE inhibitory activity,and sub-fraction F 3possessed the highest activity (more than 60%at 100l g/mL)(Table 2).The active fraction F 3was analyzed by ESI/MS and ESI/MS/MS,in order to characterize the peptide in this fraction (Fig.6a,b).The Fig.6a shows that this active fraction contained only one peptide.The accurate relative molec-ular mass of the peptide of one mass unit for the attached proton is 234Da.The Fig.6b shows the CID spectrum of the (M ?H)?ion and displays notation of fragment ions of the peptide according to this CID spectrum.According to the fragmentation of this peptide by ESI/MS/MS (Fig.6b),we determined the sequence of the peptide as Ala-Gly-Ser.This peptide has not yet been found in other protein hydrolysates with ACE inhibitory activity.TheFig.6a ESI/MS spectrum of the active fraction F3.The ion at m/z 234designated as amolecular cation (M ?H)?,Ala-Gly-Ser.b ESI/MS/MSspectrum of the active fraction F3.CID

peptide was0.13±0.03mg/mL (Table2).According to previous studies on ACE inhibitory pep-tides,hydrophobic amino acids in the N-terminal region of the active peptide plays important roles in binding the ACE active site,and leucine and valine residues are the amino acids most frequently observed in other ACE inhibitory peptides[42,43].More recently,Wu et al.[44]proposed models for ACE inhibitory peptides through computational analysis of published data.According to their proposal,the most favorable tripeptide sequences consists of hydrophobic amino acid residues at the N-terminus,positively charged amino acids at the middle position,and aromatic amino acids at the C-terminus.The ACE inhibitory peptide iden-tified here,Ala-Gly-Ser,differs from the common structural motif.The peptide had Ala at the N-terminal position,which might contribute to ACE binding.However,it contained Ser, a hydrophilic amino acid,at the C-terminal.The structure–activity correlations between the various ACE inhibitory peptides remain ambiguous.An increasing number of sequences reported in recent years have revealed a variety of structures with inhibitory activity,and some common structure patterns have evolved.According to previous reports on the structure–activity relationships between different peptide inhibitors of ACE[45],binding to ACE is strongly influenced by the C-terminal amino acid residue.Gobbetti et al.[46]reported that peptides with Trp, Tyr,Phe,Pro,or hydrophobic amino acids at the C-ter-minal were effective for ACE inhibitory activity.Several identified ACE inhibitory peptides have a proline residue in the C-terminal position,but this is neither sufficient nor essential to confer activity.Further,Cheung et al.[5] indicated that ACE prefers competitive inhibitors that contain hydrophobic amino acid residues such as Pro,Phe, and Tyr at the three positions from the C-terminal.Digestive stability of the purified peptideIn order to exert an antihypertensive effect in vivo,the ACE inhibitory peptides must be absorbed in their intact form from intestine and further be resistant to plasma peptidases degradation to reach their target sites.To investigate the resistance of the purified peptide against gastrointestinal proteases,the digestion stability was eval-uated,by incubating the purified peptide with different proteases and testing the residual ACE inhibitory activity. The ACE inhibitory activity of the peptide was not affected by in vitro incubation with gastrointestinal proteases(data not shown).This result suggests that the purified peptide may be resistant to digestion in the gastrointestinal tract. Thesefindings are in accordance with that reported by Yu et al.[19]showing the stability of globin hydrolysate against gastrointestinal proteases.Determination of ACE inhibition pattern of Ala-Gy-SerThe ACE inhibition pattern of the most potent ACE inhibitory peptide,Ala-Gly-Ser,was investigated by Li-neweaver–Burk plot(Fig.7).The kinetic study revealed that ACE inhibitor Ala-Gly-Ser acts as a non-competitive inhibitor.This indicates that the novel peptide cannot bind to catalytic site of ACE and thus could not be hydrolyzed by the enzyme.Although most of the reported peptides acted as com-petitive inhibitors for ACE,a few peptides inhibited ACE activity in a non-competitive manner have been reported, including the following:Val-Gly-Cys-Tyr-Gly-Pro-Asn-Arg-Pro-Gln-Phe from algae protein waste[47],Val-Val-Tyr-Pro-Trp-Thr-Gln-Arg-Phe from Oyster(Crassostrea talienwhanensis Crosse)proteins[48],Phe-Gly-Ala-Ser-Thr-Arg-Gly-Ala from Alaska Pollack(Theragra chalco-gramma)frame protein[49]and Ile-Phe-Leu and Trp-Leu from fermented soybean food[14].The inhibition site of the non-competitive inhibitor on ACE was not specified, and the precise inhibition mechanism of ACE inhibitory peptide is also not yet clear.ConclusionIn this study,hydrolysates from smooth hound muscle protein obtained by treatment with variousproteolyticpreparations were analyzed for their ACE inhibitory activity.The obtained results show that smooth hound muscle is a promising protein source for the production of ACE inhibitory peptides that could be utilized to develop func-tional foods for prevention of hypertension.Further works should be done to characterize potent ACE inhibitory peptides from SHPH and to determine their antihyperten-sive activity in vivo.Acknowledgment This work

GLP类似物药物进展
G L P-1类似物药物进展-截止胰高血糖素样肽(glucagon-likepeptide,GLP)是小肠表皮细胞在食物刺激情况下分泌的单肽类肠促胰岛素,包括GLP-1、GLP-2两种类型。
其中GLP-2具有促进小肠生长,抑制细胞凋亡,促进胃排空,增加食欲的药理作用,临床上可用于治疗小肠短小综合症;而GLP-1具有促进胰岛素分泌,保护胰岛β细胞,抑制胰高血糖素分泌,抑制胃排空,降低食欲的药理作用,临床可用于二型糖尿病和肥胖症的治疗。
人体内具有生物活性的GLP-1主要是GLP-1(7-36)酰胺和GLP-1(7-37),天然GLP-1可被二肽基肽酶Ⅳ(dipeptidylpeptidase-Ⅳ,DPP-Ⅳ)迅速水解失活(半衰期小于5min),不具有临床使用价值,因此对GLP-1结构修饰,掩盖DPP-Ⅳ的结合位点,延长半衰期并保证疗效是该类药物研发的主要方向。
一、已上市GLP-1类似物目前已上市的5个GLP-1类似物(表1)包括艾塞那肽(Byetta/Bydureon,byAmylin/Lilly)、利拉鲁肽(Victoza/Saxenda,byNovoNordisk)、利司那肽(Lyxumia,bySanofiAventis/Zealand)、阿必鲁肽(Tanzeum,byGSK)及杜拉鲁肽(Trulicity,byLilly):1.艾塞那肽(Exenatide)艾塞那肽(商品名Byetta)是第一个上市的GLP-1类似物,由Amylin和Lilly公司于1995年开始联合研发,2005年4月获得FDA的批准上市。
艾塞那肽源于从蜥蜴唾液中分离出的GLP-1类似物Exendin-4,与GLP-1大约有53%的同源性。
由于其N端第二位由Gly代替了GLP-1中Ala,不被DPP-Ⅳ降解,而相对天然GLP-1而言具有较长的半衰期和较强的生物活性,临床使用频率为每日2次。
AstraZeneca收购Amylin取得艾塞那肽的全球开发销售权后,开发了其缓释混悬制剂BydureonPen,并于2014年获得FDA批准。

不同浓度的葛根多糖对小鼠肠道菌群的影响陈融,刘博,陈凯,杨锐乐,王米*(中国农业科学院上海兽医研究所,农业农村部兽用化学药物及制剂学重点实验室,上海 200241)摘 要:为探究不同浓度的葛根多糖对小鼠肠道菌群的影响,本试验选取30只体重为(17.00±1.00)g的雄性昆明小鼠,按照体重被随机分为3组,每组10只,包括对照组(生理盐水)、低浓度组(12.5 mg/kg体重)、高浓度(100 mg/kg体重)组,葛根多糖连续灌服14 d后,颈椎脱臼法处死小鼠,称取胸腺、心脏、肝脏、脾脏、肺脏、肾脏和睾丸重量;收集盲肠内容物,通过GC-MS法测定肠道内短链脂肪酸浓度,并结合Illumina Miseq高通量测序技术对肠道菌群的多样性进行分析。
结果显示:2种浓度葛根多糖对于小鼠脏器指数无显著影响;与对照组相比,低浓度葛根多糖能显著降低盲肠内异丁酸和异戊酸含量,而高浓度葛根多糖仅显著降低异戊酸含量;低浓度葛根多糖能够显著提高粪球菌属(Coprococcus)、厌氧棍状菌属(Anaerotruncus)、颤螺旋菌属(Oscillospira)的相对丰度,显著降低棒状杆菌属(Corynebacterium)、葡萄球菌属(Staphylococcus)、丁酸弧菌属(Anaerostipes)、产碱菌属(Alcaligenes)的相对丰度;高浓度葛根多糖能够显著提高粪球菌属的相对丰度,使产碱杆菌属的相对丰度显著降低。
结果表明,低浓度葛根多糖能显著提高肠道菌群多样性,并改善肠道菌群结构,对机体产生有益影响。
