Synthesis of 4,5-disubstituted-3-trihalomethylisothiazoles
摘要:
Herein, we describe the synthesis of 4,5-disubstituted-3-trihalomethylisothiazoles from trihaloacetonitriles and 2-cyanothioacetamides or 2-ethoxycarbonylthioacetamides. The reactivity of the necessary trihaloacetonitriles has a significant impact on the observed reaction pathways. Reactions with CF3CN require an oxidant to mediate cyclization, while CCl3CN functions as both the reactant and oxidant. (C) 2009 Elsevier Ltd. All rights reserved.

We have discovered a novel series of isothiazole-based phenylpropanoic acids as GPR120 agonists. Extensive structure activity relationship studies led to the discovery of a potent GPR120 agonist 4x, which displayed good EC50 values in both calcium and beta-arrestin assays. It also presented good pharmaceutical properties and a favorable PK profile. Moreover, it demonstrated in vivo antidiabetic activity in C57BL/6 DIO mice. Studies in WT and knockout DIO mice showed that it improved glucose handling during an OGTT via GPR120. Overall, 4x possessed promising antidiabetic effect and good safety profile to be a development candidate.
