The synthesis and structure–activity relationship studies of selective acetyl-CoA carboxylase inhibitors containing 4-(thiazol-5-yl)but-3-yn-2-amino motif: Polar region modifications

The structure–activity relationship study focused on the polar region of the HTS hit A-80040 (1) producing several series of potent and selective ACC2 inhibitors. The SAR suggests a compact lipophilic pocket that does not tolerate polar and ionic groups. Replacement of the hydroxyurea group with isoxazoles improves ACC2 selectivity while maintaining potency. Variations at the propargylic site of 11a reduce ACC2 potency.
