α2 Adrenoceptor Agonists as Potential Analgesic Agents. 1. (Imidazolylmethyl)oxazoles and -thiazoles
摘要:
A series of (imidazolylmethyl)oxazoles and -thiazoles were prepared and evaluated as alpha(2) adrenoceptor agonists. These compounds were also tested in in vivo paradigms that are predictive of analgesic activity. Variations in both the imidazole and thiazole portions of the molecule were investigated. Some of the more potent compounds such as 22, 26, 45, and 53 displayed at receptor binding in the 10-20 nM range and also had significant, antinociceptive activity in the mouse abdominal irritant test (MAIT).

Abstract A convenient regiospecific preparation of unsymmetrical α-bromoketones, commencing from Meldrum's acid, has been developed. This procedure allows for preparation of α-bromoketones which are unobtainable in a pure state by other bromination methods and is compatable with introduction of a bromine atom in the presence of unsaturation using low-cost starting materials.
