G蛋白偶联受体40 (GPR40)是治疗二型糖尿病的潜在靶点. 本研究首先合成TAK-875 (1)作为检测GPR40激动活性的对照药物. 进一步合成化合物1的亚砜类似物11. 手性制备HPLC分离化合物11得到光学纯化合物12SS,100.0% de)和13RS,100.0% de). 其绝对构型通过圆二色谱确证. 评价化合物1 (EC50=84.3 nmol·L-1),11 (EC50=77.5 nmol·L-1),12 (EC50=76.1 nmol·L-1),13 (EC50=114.0 nmol·L-1)对GPR40的激动活性,发现所合成的化合物体外保持了对照药物的活性. 并通过计算机模拟对接的方法对活性保持的原因进行了解释. 鉴于化合物1213的良好活性与绝对构型的差别,下一步可分别对它们的成药性进行评价.

G protein coupled receptor 40 (GPR40) is a potential target for treatment of type 2 diabetes. Herein, the well-known GPR40 agonist TAK-875 (compound 1) was synthesized as a positive control. Besides, an epimeric mixture 11, which was the sulfoxide analog of compound 1 was also synthesized. The following chiral HPLC separation of 11 led to optically pure compounds 12 (S,S, 100.0% de) and 13 (R,S, 100.0% de), of which the absolute configurations were determined by circular dichroism spectra analysis. In vitro biological activity evaluation results showed that the GPR40 agonistic potency of epimeric mixture 11 (EC50=77.5 nmol·L-1) and its two optically pure epimers (12, EC50=76.1 nmol·L-1; 13, EC50=114.0 nmol·L-1) were comparable to that of compound 1 (EC50=84.3 nmol·L-1), which was rationalized by docking analysis. Compounds 12 and 13 warrant further drug-like property evaluation due to their promising potency and novel structures.
