No.:GC10546Chemical Name: 3-(carbamoylamino)-5-(3-fluorophenyl)-N-[(3S)-piperidin-3-yl]thiophene-2-carboxamideCHEMICAL PROPERTIESCas No.: 860352-01-8Molecular Formula: C17H19FN4O2SMolecular Weight: 362.42Storage: PowderSolubility: >18.1mg/mL in DMSOChemical Structure:BackgroundAZD7762 is a novel ATP competitive inhibitor of checkpoint kinases. Chk family checkpoint kinases include Chk1 and Chk2. They are activated in response to DNA damage and phosphorylate CDC25A, CDC25C protein phosphatases, which delay cell cycle progression. Therefore, Chk activation initiates cell cycle checkpoint, causes cell cycle arrest, and allows DNA repair.AZD7762 is a potent selective inhibitor of Chk1. It binds to the ATP binding pocket and compete ATP binding in a reversible manner. AZD7762 inhibits Chk1 phosphorylation of CDC25C peptide with an IC50 of 5 nM. The Ki is 3.6 nM. It is equally potent against Chk2 but less potent against CAM, Yes, Fyn, Lyn, Hck and Lck. [1]AZD7762 prevents cell cycle arrest and DNA repair in DNA damaged tumor cells, causing tumor cell apoptosis. Hence, it potentiates the antitumor activity of DNA damaging agents and can be used as a chemosensitizing agent. [2]Half life of AZD7762 is 1-2 hours in mice [3]References:[1]Polanski, R. ,Hodgkinson, C.L.,Fusi, A., et al.

Effect of Hydrofluoric Acid Concentration and Etching Time on Bond Strength to Lithium Disilicate Glass Ceramic. Oper Dent. 2017 Nov/Dec;42(6):606-615. doi: 10.2341/16-215-L. Epub 2017 Jul 14. PMID:28708007AbstractThe aim of this study was to evaluate the influence of different concentrations of hydrofluoric acid (HF) associated with varied etching times on the microshear bond strength (μSBS) of a resin cement to a lithium disilicate glass ceramic. Two hundred seventy-five ceramic blocks (IPS e.max Press [EMX], Iv oclar Vivadent), measuring 8 mm × 3 mm thickness, were randomly distributed into five groups according to the HF concentrations (n=50): 1%, 2.5%, 5%, 7.5%, and 10%.2.

PMID:27647389AbstractBACKGROUND: This study evaluated the surface morphology, chemical composition and adhesiveness of lithium disilicate glass ceramic after acid etching with hydrofluoric acid or phosphoric acid.METHODS: Lithium disilicate glass ceramic specimens polished by 600-grit silicon carbide paper were subjected to one or a combination of these surface treatments: airborne particle abrasion with 50-μm alumina (AA), etching with 5% hydrofluoric acid (HF) or 36% phosphoric acid (Phos), and application of silane coupling agent (Si).3.

Epub 2017 May 26. PMID:28552291AbstractSTATEMENT OF PROBLEM: Hydrofluoric acid etching modifies the cementation surface of ceramic restorations, which is the same surface where failure is initiated. Information regarding the influence of hydrofluoric acid etching on the cyclic loads to failure of ceramic crowns is lacking.PURPOSE: The purpose of this in vitro study was to evaluate the influence of different hydrofluoric acid concentrations on the fatigue failure loads of feldspathic ceramic crowns.。

其能有效控制餐时血糖，效果优于磺脉类降糖药，并且能降低低血糖的发生率。
据美国糖尿病学会会议上公布的临床资料显示，在用于Ⅱ型糖尿病治疗时，该药与同样具有刺激胰岛素分泌作用的其他产品相比，具有作用效果好、起效快、作用时间短和给药灵活等优点。
药品中的残留溶剂是指在合成原料药、辅料或制剂生产过程中使用或产生的挥发性有机化学物质，它们在实际生产中未能被完全清除。
近年来，药品中残存的有机溶剂的毒性和致癌作用日益引起各方面的重视［4－8］。
由于在那格列奈原药合成过程中使用了有机溶剂二氯甲烷和吡啶，因此在成品中可能会有一定量的残留。
按《中华人民共和国药典2005年版》（附录Ⅷ）规定，该2种有机溶剂均有残留限量，因此对那格列奈原药中二氯甲烷和吡啶的残留量检测具有一定意义。

专家点评
阿司咪阿司咪唑自1983年上市以来，在许多国家得到了广泛应用。国外研究显示阿司咪唑治疗荨麻疹的总有 效率为74%。国内的一项多中心双盲安慰剂对照试验表明阿司咪唑对急性荨麻疹的总有效率为82.9%，对慢性荨麻 疹的总有效率为86.0%，均显著高于安慰剂，主要不良反应为嗜睡、倦怠、口干等，连续用药3个月的患者中，半 数有食欲及体重增加。阿司咪唑的心脏毒性虽然发生率较低，但由于后果严重，已限制了它的应用。阿司咪唑为 强效和长效的H1受体拮抗剂，无中枢镇静和抗毒蕈碱样作用。代谢产物去甲阿司咪唑仍有抗胆胺作用。长期服用 可增进食欲和增加体重，服用过量可引起心脏Q-T间期延长和室性心律失常。适用于各种原因引起过敏性疾病。
