We synthesized and evaluated inhibitory activity against T-type Ca 2+ channels for a series of 1-alkyl-N-[2-ethyl-2-(4-fluorophenyl) butyl]piperidine-4-carboxamide derivatives. Structure-activity relationship studies have revealed that dialkyl substituents at the benzylic position play an important role in increasing inhibitory activity. Oral administration of N-[2-ethyl-2-(4-fluorophenyl)butyl]-1-(2-phenylethyl)piperidine-4-carboxamide (20d) lowered blood pressure in spontaneously hypertensive rats without inducing reflex tachycardia, which is often caused by traditional L-type Ca2+ channel blockers.
