While C-phenyl D-glucitol derivative SGL5213 has been reported to be a potent intestinal SGLT1 inhibitor for use in the treatment of type 2 diabetes, no SGLT1 selectivity was found in vitro (IC50 29 nM for hSGLT1 and 20 nM for hSGLT2). In this study we found a new method of synthesizing key intermediates 12 by a one-pot three-component condensation reaction and discovered C-phenyl D-glucitol 41j (TP0454614)
葡萄糖钠共转运蛋白1(SGLT1)是从胃肠道吸收葡萄糖的主要转运蛋白。虽然据报道C-苯基D-葡萄糖醇衍生物SGL5213是用于治疗2型糖尿病的有效肠道SGLT1抑制剂,但在体外未发现SGLT1选择性(hSGLT1的IC50为29 nM,hSGLT2的IC50为20 nM)。在这项研究中,我们发现了一种通过一锅三组分缩合反应合成关键中间体12的新方法,并发现了C-苯基D-葡萄糖醇41j(TP0454614),其体外SGLT1选择性> 40倍(IC50 26 nM)。对于hSGLT1,则为1101 nM;对于hSGLT2,则为1101 nM。我们的研究结果为C-葡萄糖醇衍生物的SGLT1选择性的构效关系(SAR)提供了新的见解。
