from a potent Y5 antagonist (2) with thiazole fragments that exhibit weak Y5 affinities followed by lead optimisation led to the discovery of (5,6-dihydro-4H-3-thia-1-aza-benzo[e]azulen-2-yl)-piperidin-4-ylmethyl-amino and (4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-2-yl)-piperidin-4-ylmethyl-amino derivatives. Both classes of compounds are capable of delivering potent and selective orally and centrally
一种有效的Y5拮抗剂(2)的结构元素与表现出弱Y5亲和力的噻唑片段的结合,然后进行前导优化,导致发现(5,6-dihydro-4H-3-thia-1-aza-benzo [e] azulen-2-yl)-piperidin-4-ylmethyl-amino和(4,5-dihydro-6-oxa-3-thia-1-aza-benzo [e] azulen-2-yl)-piperidin-4-ylmethyl -氨基衍生物。这两类化合物均能够递送有效的和选择性的口服和中央生物利用的NPY Y5受体拮抗剂。
