以距离比较法所获得的顺式氰基丙烯酸酯化合物的活性构象为模板,对39个该类化合物采用比较分子场方法进行了三维构效关系的研究。结果表明,所获得的药效团模型具有很好的预测能力。同时采用量子化学的方法对活性构象模板分子电子结构作了讨论。

关键词: 光系统, 抑制剂, 丙烯酸酯, 构效关系, 电子结构

3D-QSAR studies were conducted to 39(Z)-cyanoacrylate compounds by using Comparative Molecular Field Analysis (CoMFA) with five active conformations from distance Comparisons method of (Z)-cyanoacrylate compounds as templates. Th pharmacophore model showed good predictive ability. In the paper the electronic structures of the template molecules are discussed through quantum chemistry calculation.

Key words: INHIBITOR, PROPENOIC ACID ESTER, STRUCTURE ACTIVITY RELATIONSHIP, ELECTRONIC STRUCTURE
