Rational design, efficient syntheses and biological evaluation of N , N ′-symmetrically bis-substituted butylimidazole analogs as a new class of potent Angiotensin II receptor blockers
symmetrically bis-substituted imidazoleanalogs bearing at the N-1 and N-3 two biphenyl moieties ortho substituted either with tetrazole or carboxylate functional groups was designed based on docking studies and utilizing for the first time an extra hydrophobic binding cleft of AT1 receptor. The synthesized analogs were evaluated for their in vitro antagonistic activities (pA2 values) and binding affinities
