Herein we describe structure-activity relationship (SAR) and metabolite identification (Met-ID) studies that provided insight into the origin of time-dependent inhibition (TDI) of cytochrome P450 3A4 (CYP3A4) by compound 1. Collectively, these efforts revealed that bioactivation of the fluoropyrimidine moiety of 1 led to reactive metabolite formation via oxidative defluorination and was responsible for the observed TDI. We discovered that substitution at both the 4- and 6-positions of the 5-fluoropyrimidine of 1 was necessary to ameliorate this TDI as exemplified by compound 19.
DISUBSTITUTED OCTAHY-DROPYRROLO [3,4-C] PYRROLES AS OREXIN RECEPTOR MODULATORS

Page/Page column 84, (2012/11/07)
Disubstituted octahydropyrrolo[3,4-c]pyrrole compounds are described, which are useful as orexin receptor modulators. Such compounds may be useful in pharmaceutical compositions and methods for the treatment of diseased states, disorders, and conditions mediated by orexin activity, such as insomnia.

Certain disubstituted 3,8-diaza-bicyclo[4.2.0]octane and 3,6-diazabicyclo [3.2.0]heptane are described, which are useful as orexin inhibitors. Such compounds may be useful in pharmaceutical compositions and methods for the treatment of diseased states, disorders, and conditions mediated by orexin activity, such as insomnia.
