Novel 3,6-disubstituted pyridazines were synthesized by facile method and screened for their vasorelaxant properties utilizing isolated thoracic rat aortic rings. Compounds 8a and 11a exerted potent vasorelaxant activity (IC50 = 198 and 177 μM, respectively) relative to doxazosin mesylate (used reference standard, IC50 = 226 μM), that, they may represent promising hits for treatment of cardiovascular disorders. The observed activity was validated by a statistically significant QSAR model (N = 32, n = 6, R2 = 0.811782, R2cvOO = 0.7153, R2cvMO = 0.7209, F = 17.9708, s2 = 9.65226 × 10-8) that was obtained employing CODESSA-Pro software.
