Abstract :
New analogues of nifedipine, as a known calcium channel blocker, were synthesized by
replacing the orthonitrophenyl group on position 4 with 1-(4-Nitrobenzyl)-5-imidazolyl or 2-
methylthio-1-(4-Nitrobenzyl)-5-imidazolyl substituent. Effects of the new synthesized
compounds on blood pressure were studied at 15, 30 and 60 min after administration by indirect
tail-cuff method and compared with nifedipine in male rat.
The results indicate that all compounds reduce mean systolic blood pressure but their
effectiveness is less than nifedipine. The onset of action of compounds 6c ,6d ,6e and 6g is also
slower than the parent drug.
