【Abstract】 D QSAR studies of (Z) cyanoacrylate compounds are conducted by using Comparative Molecular Field Analysis(CoMFA). The pharmacophore model shows good predictive ability. The distance map shows that the four points are the phenyl center(hydrophobic center *,Carbonyl (O ** ) and (C #)atoms, and ethyloxy O ( ## ) atom. The distances between above atoms are as follows: *—** 0.368 7 nm,*—# 0.365 6 nm,##—**0.395 0 nm,##—# 0.3950 nm. In the paper the non uniqueness of pharmacophore is discussed.更多还原
