Deuterated analogs of verapamil and nifedipine. Synthesis and biological activity
摘要:
The preparations of various deuterium analogs of verapamil and nifedipine have been described. Deuterium is incorporated at specific positions in the molecules in 97% isotopic purity. The deuterated analogs 1d of verapamil and 2d of nifedipine lowered blood pressure in spontaneously hypertensive rats with a profile that was, for the most part. similar to the parent compounds. It was therefore concluded that deuterium substitutions fail to significantly alter the metabolism of verapamil or nifedipine in vivo.
