摘要:
Seven cyclohexane-bearing C-glucoside derivatives (7, 9, 12, 13 and 17-19) were designed and synthesized as SGLT2 inhibitors starting from a potent SGLT2 inhibitor we discovered in earlier work, (1S)-1-deoxy-1-[4-methoxy-3-(trans-n-propylcyclohexyl)methylphenyl]-D-glucose (1). The in vitro and in vivo biological activities were evaluated by hSGLT2/hSGLT1 inhibition and urinary glucose excretion (UGE), respectively. Among the synthesized compounds 12, the 6-deoxy derivative of 1 was the most active and selective SGLT2 inhibitor (IC50 = 1.4 nmol/L against hSGLT2; selectivity = 1576). Compound 12 was a potent SGLT2 inhibitor, which could induce more urinary glucose than 1 and dapagliflozin in UGE. (C) 2013 Gui-Long Zhao, Jian-Wu Wang.
