known to play an important catalytic role in the final step 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 cyclohexanecarboxylic acid (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。
