摘要:
The serendipitous discovery of N-cyclohexyl-8-fluoro-3,3a,4,9b-tetrahydro-1H-thiochromeno[4,3-c]isoxazole-1-carboxamide as a selective human serotonin 5-HT2B antagonist with K-i of 42 +/- 5 nM is reported herein. A subsequent functional assay indicated little agonist activity compared to 5-HT itself. (c) 2010 Elsevier Ltd. All rights reserved.
