As part of an effort to identify 5-HT1A antagonists that did not possess typical arylalkylamine or keto/amido-alkyl aryl piperazine scaffolds, prototype compound 10a was identified from earlier work in a combined 5-HT 1A antagonist/SSRI program. This quinolyl-piperazinyl piperidine analogue displayed potent, selective 5-HT1A antagonism but suffered from poor oxidative metabolic stability, resulting in low exposure following oral administration. SAR studies, driven primarily by in vitro liver microsomal stability assessment, identified compound 10b, which displayed improved oral bioavailability and lower intrinsic clearance. Further changes to the scaffold (e.g., 10r) resulted in a loss in potency. Compound 10b displayed cognitive enhancing effects in a number of animal models of learning and memory, enhanced the antidepressant-like effects of the SSRI fluoxetine, and reversed the sexual dysfunction induced by chronic fluoxetine treatment.
Selective and efficient structural elaboration of 2-(trifluoromethyl)quinolinones

The acid-catalyzed cyclization-condensation between anilines and ethyl 4,4,4-trifluoroacetoacetate affords 1,4-dihydro-2-trifluoromethyl-4H-4-quinolinones (1), which can easily be converted into 4-bromo-2-(trifluoromethyl)quinolines. These undergo halogen/metal exchange, generating 2-trifluoromethyl-4-quinolyllithiums, when treated with butyllithium, and hydrogen/metal exchange, generating 4-bromo-2-trifluoromethyl-3-quinolyllithiums, when treated with lithium diisopropylamide. Trapping of the latter intermediates provides 3-functionalized products that may be further elaborated by electrophilic substitution of the bromine atom. A few unexpected findings resulted from these investigations, the most noteworthy being an unprecedented buttressing effect and a counterintuitive halogen reactivity. ( Wiley-VCH Verlag GmbH & Co.
