Evaluation of thiazole containing biaryl analogs as diacylglycerol acyltransferase 1 (DGAT1) inhibitors
摘要:
Biphenyl carboxylic acids, exemplified by compound 5, are known potent inhibitors of diacylglycerol acyltransferase, DGAT1, an enzyme involved in the final committed step of triglyceride biosynthesis. We have synthesized and evaluated 2-phenylthiazole, 4-phenylthiazole, and 5-phenylthiazole analogs as DGAT1 inhibitors. The 5-phenylthiazole series exhibited potent DGAT1 inhibition when evaluated using an in vitro enzymatic assay and an in vivo fat tolerance test in mice. Compound 33 (IC50 = 23 nM) exhibiting promising oral pharmacokinetic parameters (AUC(inf) = 7058 ng*h/ml, T-1/2 = 0.83 h) coupled with 87 percent reduction of plasma triglycerides in vivo may serve as a lead for developing newer anti-obesity agents.

with this class of compounds. The structure-activity relationships (SAR) here discussed evidenced the importance of the furan as part of the pharmacophore and led to the preparation of six newcompounds (IV–IX), which gave us the opportunity to examine a hitherto unexplored position of the phenyl ring. Among them emerged 5-(3-cyano-5-(trifluoromethyl)phenyl)furan-2-carboxylic acid (IV), endowed with comparable
结核病(TB)每年导致数百万人死亡,是全球最危险的传染病之一。由于结核分枝杆菌(Mtb) 的几种致病菌株已经对大多数现有的抗结核药物产生了耐药性,因此迫切需要新的治疗选择。开发新型抗结核药物的一个有吸引力的目标是水杨酸合酶 MbtI,它是分枝杆菌铁载体生化机制的必需酶,而人类细胞中不存在这种酶。 I和II是迄今为止鉴定出的两种最有效的 MbtI 抑制剂,其一组类似物经过合成、表征和测试,以阐明此类化合物实现有效 MbtI 抑制和有效抗结核活性的结构要求。这里讨论的构效关系 (SAR) 证明了呋喃作为药效基团一部分的重要性,并导致了六种新化合物 ( IV – IX ) 的制备,这使我们有机会检查迄今为止尚未探索的苯基位置戒指。其中出现了5-(3-氰基-5-(三氟甲基)苯基)呋喃-2-羧酸( IV ),其具有与之前的先导化合物相当的抑制特性,但具有更好的抗结核活性,这是MbtI的关键问题抑制剂
Synthesis and evaluation of cyclohexane carboxylic acid head group containing isoxazole and thiazole analogs as DGAT1 inhibitors
known to play an important catalytic role in the finalstep of triglyceride biosynthesis. High fat diet fed DGAT1 knockout mice were resistant to weight gain and exhibited increased insulin and leptin sensitivity thereby indicating a plausible role for DGAT1 inhibitors in the treatment of obesity. 4-Phenylpiperidine-1-carbonyl cyclohexanecarboxylicacid (compound 6, DGAT1 IC50 = 57 nM) has been lately
已知甘油二酰基酰基转移酶1(DGAT1)在甘油三酸酯生物合成的最终步骤中起重要的催化作用。高脂肪饮食喂养的DGAT1基因敲除小鼠对体重增加有抵抗力,并且胰岛素和瘦素敏感性增强,从而表明DGAT1抑制剂在肥胖症治疗中的作用似乎是合理的。 最近已经报道了4-苯基哌啶-1-羰基环己烷羧酸(化合物6,DGAT1 IC 50 = 57 nM)作为有效的DGAT1抑制剂。在寻找具有强大DGAT1活性的新型支架时,我们对化合物6进行了系统的多样化研究,以鉴定出4-(5-苯基噻唑-2-羧酰胺基)环己烷羧酸支架。此支架鉴定化合物的进一步接头优化9e(DGAT1 IC 50 = 14.8 nM)作为有效的DGAT1抑制剂。结合其体外功效,当在瑞士小鼠中进行研究时,在口服脂肪耐受性测试(FTT)中,化合物9e在3 mpk剂量下还显示出112%的血浆甘油三酸酯减少。
