Design, synthesis, and evaluation of a novel 4-aminomethyl-4-fluoropiperidine as a T-type Ca2+ channel antagonist.
The novel T-type antagonist ( S)- 5 has been prepared and evaluated in in vitro and in vivo assays for T-type calcium ion channel activity. Structural modification of the piperidine leads 1 and 2 afforded the fluorinated piperidine ( S)- 5, a potent and selective antagonist that displayed in vivo CNS efficacy without adverse cardiovascular effects.
