Identification of a 5-HT4 receptor antagonist clinical candidate through side-chain modification
摘要:
Replacement of the N-butyl side-chain of lead 5-HT4 receptor antagonist 2 with propanesulfonylpiperidinyl, morpholinyl, and piperazinyl groups led to higher affinity analogs 4-6. In vitro drug metabolism screens and cassette pharmacokinetic studies in the dog led to identification of the N-methylpiperazinyl analog (6b), which displayed pharmacokinetic, selectivity, and safety parameters sufficient for advancement to the clinic for the treatment of urinary incontinence.
