Synthesis and Biological Evaluation of Cyclopentaquinoline Derivatives as Nonsteroidal Glucocorticoid Receptor Antagonists
摘要:
The steroidal glucocorticoid antagonist mifepristone has been reported to improve the symptoms of depression. We report the discovery of 6-(3,5-dimethylisoxazol-4-yl)-2,2,4,4-tetramethyl-2,3,4,7,8,9-hexahydro-1H-cyclopenta[h]quinolin-3-one 3d (QCA-1093) as a novel nonsteroidal glucocorticoid receptor antagonist. The compound displayed potent in vitro activity, high selectivity Over other steroid hormone receptors, and significant antidepressant-like activity in vivo.

structure-affinity relationships for alpha 2- vs. alpha 1-adrenergic receptors are considered. Compound 2a, 8-(1-piperazinyl)imidazo[1,2-a]pyrazine, is equipotent with mianserin on the clonidine receptor (alpha 2) but ca. 70 times as selective as mianserin for this alpha 2-adrenergic receptor. Reduction of the imidazo ring (2,3-dihydro) lowers affinity for the alpha 2 receptor without affecting alpha 1-receptor
