Effectively used for the treatment of various depressions. Fluoxetine hydrochloride has been shown to have comparable efficacy to tricyclic antidepressants but with fewer anticholinergic side effects. The patent expiry becomes effective in 2001 (US). INTRODUCTIONFluoxetine capsules were prepared in two dosage strengths: 10mg and 20mg dosage strengths with the same capsule weight. The formulas are essentially similar and geometrically equivalent with the same ingredients and proportions. Minor changes in non-active proportions account for the change in active ingredient amounts from the 10 and 20 mg strength.The following validation, for the method SI-IAG-206-02 , includes assay and determination of Meta-Fluoxetine by HPLC, is based on the analytical method validation SI-IAG-209-06. Currently the method is the in-house method performed for Stability Studies. The Validation was performed on the 20mg dosage samples, IAG-21-001 and IAG-21-002.In the forced degradation studies, the two placebo samples were also used. PRECISIONSYSTEM REPEATABILITYFive replicate injections of the standard solution at the concentration of 0.4242mg/mL as described in method SI-IAG-206-02 were made and the relative standard deviation (RSD) of the peak areas was calculated.SAMPLE PEAK AREA#15390#25406#35405#45405#55406Average5402.7SD 6.1% RSD0.1ED.

It is the limit of detection of shape differences between two spectra.Match Angle-is a comparison of the spectrum at the peak apex against a library spectrum.Match Threshold-is the sum of the match noise angle3 and match solvent angle4.3Noise Angle-is a measure of spectral non-homogeneity caused by system noise.4Solvent Angle-is a measure of spectral non-homogeneity caused by solvent composition.OVERVIEWT he assay of the main peak in each stressed solution is calculated according to the assay method SI-IAG-206-02, against the Standard Solution, injected on the same day.I f the Purity Angle is smaller than the Purity Threshold and the Match Angle is smaller than the Match Threshold, no significant differences between spectra can be detected. As a result no spectroscopic evidence for co-elution is evident and the peak is considered to be pure.T he stressed condition study indicated that the Fluoxetine peak is free from any appreciable degradation interference under the stressed conditions tested. Observed degradation products peaks were well separated from the main peak.1® PDA-996 Waters™ ; 2[Millennium 2010]ED.

阿西替尼片剂的实验设计

阿西替尼片剂的实验设计

班级: xxxx 学号: 1234567 姓名 : xxx 阿西替尼红膜包衣片剂的实验设计一.立题目的和依据1.阿西替尼的相关性质中文化学名称:N-甲基-2-((3-((1E)-2-(吡啶-2-基)乙烯)- 1H-吲唑-6-基)硫)苯甲酰胺; 英文化学名称:N-methyl-2-((3-((1E)-2-(pyridin-2-yl)ethenyl)-1H-indazol-6-yl)sul-fanyl)benzamide; 分子式: C22 H18 N4OS; 分子量:386.47。

物理性状及指标:外观:类白色至浅黄色粉末溶解性:溶于DMSO (42 mg/ml,25 °C),水(<1 mg/ml,25 °C),乙醇(<1mg/ml,25 °C),甲醇和DMF (~0.25 mg/ml). 在水介质中溶解度范围跨度pH 1.1至pH 7.8是超过0.2 μg/mL。

分配系数(正辛醇/水)是3.5。

密度:~1.4 g/cm3 (预测)干燥失重:≤0.5%含量:99.0%~101.0%2.用途及药理作用的描述阿西替尼能够抑??制受体酪氨酸激酶,选择性作用于VEGF受体1、2和3等靶点。

这些受体已被证实在病理性血管生成、肿瘤的生长和癌症发展中起到作用。

同时也是一种科研试剂,广泛应用于分子生物学,药理学等科研方面。

阿西替尼主要靶向于VEGFR酪酸激酶、抑制血管生成的小分子抗癌药。

药理作用:研究表明,阿西替尼能强效、选择性的抑制VEGF依赖性受体磷酸化,对VEGFR-1、VEGFR-2、EGFR-3的半数抑制浓度(IC50)分别为1.2,0.25和0.29nmol/L。

VEGFR被抑制后,下游的信号传递继而被中段,最终导致细胞无法增殖、甚至死亡。

但阿西替尼对成纤维细胞生长因子引起的细胞生长没有抑制作用。

3.研究依据和立题目的近年来,在抗肿瘤药的研制中,靶向血管生成和血管内皮生长因子(VEGF)的药物已成为热点。

Design and synthesis of urea and thiourea derivatives and their inhibitory activities on lipopolysaccharide-inducedNO productionYoon Jung Kim,Jae-Ha Ryu,Ye Jin Cheon,Hyo Jin Lim and Raok Jeon *College of Pharmacy,Sookmyung Women’s University,52Hyochangwon-Gil,Yongsan-Ku,Seoul 140-742,Republic of KoreaReceived 17November 2006;revised 20March 2007;accepted 2April 2007Available online 6April 2007Abstract—Series of ureas and thioureas were designed and synthesized,and their inhibitory activities of NO production in lipopoly-saccharide-activated macrophages were evaluated.We found several essential moieties in the structure of the prepared compounds for the activity.Thiourea derivatives revealed higher inhibitory activity than the corresponding urea derivatives.Among these com-pounds,7e having carboxymethyl group at N3position of thiourea was the most potent in the inhibition of NO production.They inhibited NO production through the suppression of iNOS protein and mRNA expression.Ó2007Elsevier Ltd.All rights reserved.The critical role of nitric oxide (NO)in various patho-logical conditions has led to the discovery of new inhib-itors of NO production as potential therapeutic agents.NO,a gaseous free radical,is produced through the oxi-dation of L -arginine by three isoforms of nitric oxide synthase (NOS).1The constitutive NOS (cNOS)found in neuronal tissues (nNOS,type I)and vascular endo-thelium (eNOS,type III)is Ca 2+-dependent and releases small amounts of NO required for homeostatic func-tion.2Meanwhile,inducible NOS (iNOS,type II),which can be induced by lipopolysaccharide (LPS)and various cytokines such as IFN-a ,IL-1b ,and TNF-a ,is Ca 2+-independent and produces micromolar levels of NO.3Low concentrations of NO produced by iNOS possess beneficial roles in antimicrobial activity of macrophages against pathogens,4while the overproduction of NO and its derivatives,such as peroxynitrite and nitrogen diox-ide,has been suggested to be mutagenic in vivo and to provoke the pathogenesis of septic shock and various inflammatory processes.5Furthermore,NO and its oxi-dized forms have also been known to be carcinogenic.6Among the many strategies for providing rational con-trol of NO levels,the efforts have been mainly directed toward development of selective inhibitor of iNOS thatcan be applied for the treatment of diseases accompany-ing high levels of NO.Regulation of iNOS can be achieved by the control of expression level and/or enzy-matic activity of iNOS.Many classes of iNOS inhibitors can be classified according to their structural features,such as,amino acid analogues,7amino heterocycles,8amidines,9guanidines,10isoquinolinamines,11and isot-hiourea.12,13But most of the inhibitors are neither po-tent nor selective enough against NOS isoforms,that limited the application of them in vivo.Only one class of iNOS inhibitors,L -lysine analogue,was reported to enter the clinical trial in human.14Urea was known to inhibit not only the activity of iNOS in macrophages during the uremia,15but also the expres-sion of iNOS in LPS-activated macrophages.16Urea was suggested as an important modulator for renal function through the fine tuning of NO production.17Several groups have reported that urea and thiourea 18or iso-thiourea 12,13,19inhibit iNOS expression and/or NO pro-duction.Based on these reports,we tried to investigate urea and thiourea derivatives as novel inhibitors having mechanism for enzymatic inhibition and/or downregula-tion of iNOS expression.Herein,we report the design and synthesis of urea and thiourea derivatives as depicted in Figure 1.Their effects on the NO production and expression of iNOS were evaluated in LPS-activated macrophage cell culture system.0960-894X/$-see front matter Ó2007Elsevier Ltd.All rights reserved.doi:10.1016/j.bmcl.2007.04.005Keywords :Urea;Thiourea;Carbazole;Nitric oxide synthase;Nitric oxide;Inhibitor.*Corresponding

outlined in Schemes 1and 2.Hydroxy ethyl group was introduced at nitrogen of carbazole and the resulting alcohol 2was mesylated to obtain com-pound 3.Alkylation of 4-nitrophenol by treatment of compound 3in the presence of NaH gave compound 4.Following reduction of nitro compound 4over 10%Pd/C under atmospheric pressure of hydrogen gas pro-vided amine 5.Condensation of amine 5with the appro-priate isocyanates or isothiocyanates offered the desired compounds 6and 7.The activities of the prepared compounds were evalu-ated for the inhibition of NO production in LPS-acti-vated macrophages.Murine macrophage cell line,RAW 264.7cells,was stimulated with 1l g/mL of LPS in the presence of samples for 20h.The amounts of NO released into culture media were determined by the Griess method 20in the form of nitrite.21The inhibitory activities of the prepared compounds on the NO production are given in Table 1.Aminoguani-dine,a well-known specific inhibitor of iNOS,was usedas positive control that showed 85%inhibition of NO production at 0.1l M.Most of the thiourea derivatives revealed higher activity than the corresponding urea derivatives.For example,thioureas 7a ,7c ,7e ,and 7f showed significantly higher activities than ureas 6a ,6b ,6g ,and 6i ,respectively.Effects of the alkyl substituents at the N1and N3posi-tion of urea 6a and thiourea 7a were investigated.Intro-duction of methyl group 6h at the N1position of urea 6a lowered the activity,while introduction of bulkier sub-stituent retrieved the pound 6i with ethyl group showed the similar activity as 6a .Meanwhile,activity of compound 6j with cyclopropylmethyl at N1became 2.5-fold higher than that of 6a .On the other hand,thiourea derivatives 7f substituted with ethyl and 7g with cyclopropylmethyl at N1of 7a revealed 2-fold lower activity than 7a .The effects of substituents at N3position were consider-ably different between urea and thiourea derivatives.While the substitution at N3of urea derivatives 6b–6g showed no significant effects on the activity,the alkyl substitution of thiourea greatly enhanced the pounds 7b ,7c ,7e with methyl,ethyl,or carboxym-ethyl group at N3revealed similar activity ranging from 80%to 90%inhibition of NO production at 5l M con-centration.In both cases of ureas and thioureas,the carboxymethyl was the best substituent at N3for the improvement of activity.IC 50values of 6j ,7a–7c ,and3318Y.J.Kim et al./Bioorg.Med.Chem.Lett.17(2007)3317–33217e,which showed more than50%inhibitory responses at 5l M,were determined as3.12,5.31,0.73,0.90,and 0.15l M,respectively.In order tofind the influence of lipophilic tail on the activity,carbazolylmethyl group of thiourea derivatives 7b–7c was eliminated.These compounds showed lower activities,less than15%inhibition of NO production at5l M,than the corresponding carbazole-linked thiou-reas.It has been reported that a carbazole derivative inhibited iNOS expression in the LPS-activated macro-phage.22Our results also demonstrated that both thio-urea and carbazole moieties might play an important role for their activities although carbazole moiety devoid of thiourea group revealed no activity.We expect to potentiate the activity by the structural modification of thiourea and lipophilic segment.For the further biological study of our derivatives,we examined the effects of6j,7a–7c,and7e on the expres-sion of iNOS protein and mRNA in LPS-activated RAW264.7cells.The amounts of iNOS protein were analyzed in Western blot analysis after20-h incubation with compounds during LPS(1l g/mL)activation ofmacrophages.23Compounds7b and7e significantly reduced the amounts of iNOS at10l M(Fig.2).At RT-PCR analysis,24the expression level of iNOS mRNA was increased markedly by LPS-activation for pounds7b and7e suppressed the induction of iNOS mRNA at10l M(Fig.3).These results indicated that the inhibition of NO production by thiourea deriv-atives resulted from the suppression of iNOS protein and mRNA.When we treated the compounds after the completion of iNOS induction by LPS(post-treatment),they showed weak activity compared with the results of the co-treat-ment of compounds with LPS.Even the most potent compound7e showed12%inhibition at10l M by post-treatment.These results suggested that thiourea derivatives exhibited their activities mainly through the inhibition of iNOS expression with marginal inhibi-tion against enzymatic activity.It has been reported that urea itself inhibited the activity of iNOS by transcrip-tional15and post-transcriptional16mechanisms.Many of thioureas and isothioureas were reported12,25as inhibitors of iNOS enzyme devoid of controlling the expression step.In addition,a carbazole

mRNA expression through a signaling pathway that does not involve NF-j B pathway.22The exact difference between the mecha-nism of our compounds and that of the reported thioureas and carbazole derivative was not explained in this report. The study of the mechanism for the iNOS inhibition by our compounds might be worthy to pursue further.In conclusion,we prepared a series of urea and thiourea derivatives and evaluated their inhibitory activities of NO production in LPS-activated macrophages.They suppressed the release of NO into culture media through the suppression of iNOS protein and mRNA expression. The SAR studies demonstrated that thiourea is superior to urea and N3substitution of thiourea with alkyl group is highly beneficial for their activity.Further study of the other biological activities related with the overproduc-tion of NO,and the detailed mechanism for the activities of these derivatives,is in progress.Our thiourea deriva-tives that can control the expression of iNOS can be good leads for the development of therapeutic agents for the management of NO-related diseases.AcknowledgmentThis work was supported by the SRC program of MOST/KOSEF(R11-2005-017,RESEARCH CEN-TER FOR

Alda-1_DataSheet_MedChemExpress

Alda-1_DataSheet_MedChemExpress

Inhibitors, Agonists, Screening Libraries Data SheetBIOLOGICAL ACTIVITY:Alda–1 is a potent ALDH2 agonist, which significantly improves ALDH2 activity.In Vivo: Alda–1 treatment results in a significant decrease of 4–HNE–protein content in the plasma of apoE -/- mice. Alda–1administration leads to a slight increase in gene expression related to neurogenesis (Nog ), mitochondrial biogenesis (CYTB , ND1),and apoptosis (Bax , Gsk3b ) in the Hp of apoE -/- mice. Alda–1 administration leads to 2 and 10 differentially expressed proteins in theFCx and Hp of apoE -/- mice, respectively [1]. Alda–1 (1.5 mg/kg, b.w., i.p.) administration significantly increases the climbing time,tends to reduce the immobility time and increases the swimming time of the prenatally stressed rats in the forced swim test.Moreover, treatment of prenatally stressed rats with Alda–1 significantly increases number of entries into the open arms of the maze and the time spent therein, as assessed by elevated plus–maze test [2]. Alda–1 (8.5 mg/kg, i.p.) with glucose significantly lowers 4–HNE and FJB–positive cells in the cerebral cortex of Alda–1–treated rats than in DMSO–treated rats 24 h after glucose administration [3]. Alda–1 (10 mg/kg per day) treatment prevents aldehydic overload, mitochondrial dysfunction and improves ventricular function in post–MI cardiomyopathy rats [4].PROTOCOL (Extracted from published papers and Only for reference)Cell Assay:[2]Spleen cells (4×106 cells/mL) are stimulated by optimal concentrations of concanavalin A (Con A; 2.5μg/mL and 0.6 μg/mL) and lipopolysaccharide (LPS, 5 μg/mL) and are incubated in 96–well plates at final volume of 0.2mL for 72 h. Cell proliferation is determined by adding 0.5 μCi of [3H]–thymidine per well at 16 h before the end of the incubation.The cultures are harvested with an automatic cell harvester, and [3H] thymidine incorporation is assessed using a liquid scintillationcounter.Animal Administration: Alda–1 is dissolved in 1 mL/kg b.w. DMSO/water 50/50.[2]After behavioral verification at three months of age,the animals are divided into the following four groups: control, control + Alda–1, prenatally stressed and prenatally stressed + Alda–1(6 animals per group). Alda–1 injections are given intraperitoneally (i.p.) once daily at a dose of 1.5 mg/kg b.w. (dissolved in 1 mL/kg b.w. DMSO/water 50/50) for 14 days. At the same time, the control and prenatally stressed rats receive 1 mL/kg b.w. DMSO/water 50/50. The injections of Alda–1 and vehicle are given between 10 a.m and 11 a.m. In the last five days of Alda–1 treatment the behavioral parameters in the elevated plus maze test and then in the forced swim test are measured.References:[1].
