Synthesis and 5-Hydroxytryptamine (5-HT) activity of 2,3,4,4a-Tetrahydro-1H-pyrazino[1,2-a]quinoxalin-5-(6H)ones and 2,3,4,4a,5,6-Hexahydro-1H-pyrazino[1,2-a]quinoxalines
摘要:
A series of 2,3,4,4a-tetrahydro-1H-pyrazino[1,2-a]quinoxalin-5-(6H)ones and 2,3,4,4a,5,6-hexahydro-1H-pyrazino[1,2-a]-quinoxalines was shown to exhibit 5-HT2C agonist binding and Functional activity. Compound 21R inhibited food intake over 2 h in fasted, male Sprague-Dawley rats with ED50 values of 2 mg/kg (ip) and 10 mg/kg (po). (C) 2000 Elsevier Science Ltd. All rights reserved.
