Discovery and SAR of potent, orally available and brain-penetrable 5, 6-dihydro-4H-3-thia-1-aza-benzo [e] azulen-and 4, 5-dihydro-6-oxa-3-thia-1-aza-benzo [e] …
Combination of structural elements 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 ...
