Discovery of novel thiourea 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, we prepared a novel series of phenoxypropanolamine derivatives containing the thiourea moiety and evaluated their biological activities at human beta 3-, beta 2-, and beta 1-ARs. Among these compounds, 4-nitrophenylthiourea (18i) and 3-methoxyphenylthiourea (18k) derivatives were found to exhibit potent agonistic activity at the b3-AR, with EC(50) values of 0.10 and 0.16 mu M, respectively, and no agonistic activity for either the beta 1-or beta 2-AR. In addition, they showed significant hypoglycemic activity in a rodent diabetic model. (C) 2009 Elsevier Ltd. All rights reserved.
A borontrifluoride–methanolcomplex demonstrated remarkable deprotection selectivity against commonly used amino-protecting groups in the deacetylation of acetanilides and high sensitivity to the steric hindrance of substrates. The scope and limitations of the reaction were explored.

An improved method for reducing aromatic nitro compounds on solid-phase supports usingsodium hydrosulfite is presented. Conditions have been optimized to enable the use of this reagent for reductions on both polyethyleneglycol-polystyrene (PEG) resins and traditional polystyrene (PS) resins.
