1, 4-Dihydropyridine derivatives having two nitrooxyalkyl moieties as esters at the 3 and 5 positions possess antihypertensive activity. To understand how substituents affect the biological activity, the quantitative structure-activity relationship (QSAR) of 27 compounds was analyzed using the Fuzzy adaptive least-squares (FALS 91) method. The QSAR models suggested that the hydrophobicity and electronic effect at the 4 position of the 1, 4-dihydropyridine along with the special structures of the nitrooxyalkylester components are important for antihypertensive activity.
