  Discovery of novel acetanilide derivatives as potent and selective β3-adrenergic receptor agonists

  摘要：

  In the search for potent and selective human beta 3-adrenergic receptor (AR) agonists as potential drugs for the treatment of obesity and noninsulin-dependent (type II) diabetes a novel series of acetanilide-based analogues were prepared and their biological activities were evaluated at the human beta 3-, beta 2-, and beta 1-ARs. Among these compounds, 2-pyridylacetanilide (2f), pyrimidin-2-ylacetanilide (2u), and pyrazin-2-ylacetanilide (2v) derivatives exhibited potent agonistic activity at the beta 3-AR with functional selectivity over the beta 1- and beta 2-ARs. In particular, compound 2u was found to be the most potent and selective beta 3-AR agonist with an EC(50) value of 0.11 mu M and no agonistic activity for either the beta 1 - or beta 2-AR. In addition, 2f, 2u, and 2v showed significant hypoglycemic activity in a rodent diabetic model. (C) 2009 Elsevier Masson SAS. All rights reserved.

  An Ir(III)-catalyzed C(3)–H alkylation of N-acetyl-1,2-dihydroisoquinolines with diverse acceptor–acceptor diazo compounds has been achieved under a single catalytic system via metal carbene migratory insertion. Moreover, further synthetic transformations of the alkylated products such as aromatization, selective decarboxylation, and decarbonylation lead to the formation of several synthetically viable
