The present invention relates to novel inhibitors of adipose triglyceride lipase (ATGL) having an improved inhibitory activity against human ATGL (hATGL) as well as pharmaceutical compositions comprising these inhibitors, and their therapeutic use, particularly in the treatment or prevention of a lipid metabolism disorder, including, e.g., obesity, non-alcoholic fatty liver disease, type 2 diabetes, insulin resistance, glucose intolerance, hypertriglyceridemia, metabolic syndrome, cardiac and skeletal muscle steatosis, congenital generalized lipodystrophy, familial partial lipodystrophy, acquired lipodystrophy syndrome, atherosclerosis, or heart failure.

Synthesis and structure–activity relationship of a new class of muscarinic M3 selective antagonists were described. In the course of searching for a muscarinic M3 antagonist with a structure distinct from those of the 2-(4,4-difluorocyclopentyl)-2-phenylacetamide derivatives, we identified a thiazole-4-carboxamide derivative (1) as a lead compound in our in-house chemical collection. Since this compound (1) showed relatively low binding affinity (Ki=140 nM) for M3 receptors in the human binding assays, we tried to improve its potency and selectivity for M3 over M1 and M2 receptors by derivatization of 1 through a combinatorial approach. A solution-phase parallel synthesis effectively contributed to the optimization of each segment of 1. Thus, we have identified a cyclooctenylmethyl derivative (3e) and a cyclononenylmethyl derivative (3f) as representative M3 selective antagonists in this class.
