Robust pharmaceutical treatment of obesity has been limited by the undesirable side-effect profile of currently marketed therapies. This paper describes the synthesis and optimization of a new class of pyrazinoisoindolone- containing, selective 5-HT2C agonists as antiobesity agents. Key to optimization of the pyrazinoisoindolone core was the identification of the appropriate substitution pattern and functional groups which led to the discovery of (R)-9-ethyl-1,3,4,10b-tetrahydro-7-trifluoromethylpyrazino[2,1-a] isoindol-6(2H)-one (58), a 5-HT2C agonist with > 300-fold functional selectivity over 5-HT2B and > 70-fold functional selectivity over 5-HT2A. Oral dosing of 58 reduced food intake in an acute rat feeding model, which could be completely reversed by a selective 5-HT2C antagonist and caused a reduction in body weight gain in a 4-day rat model.

Experiments are reported here to develop compounds with antiestrogenic and mammary tumor inhibiting properties. Analogues with hydrophobic groups in 2- or 2,6-position of the benzamide-fragment of N-(4-hydroxyphenyl)-N-(1,1,1-trifluoro-2-propyl)-4-hydroxy
