摘要
对3 , 5 - 二芳基s三氮唑类化合物的终止妊娠活性进行了量子化学和 B P 人工神经网络研究。结果表明, 疏水键和电荷转移复合作用等是影响这类化合物终止妊娠活性的主要因素。以分子van der Waals 体积、偶极矩、 E H O M O、三氮唑环上氮的原子电荷、 E L U M O、疏水常数作为输入参数建立的 B P 网络综合了输运、代谢对活性的影响, 并给出了满意的预测结果。
AM1 and BP artificial neural network were employed to study the pregnancy\|terminating activity of 3,5-diaryl\|s\|triazoles. They suggested that the hydrophobic bond and the charge\|transfer complex were primary factor influenced activity. Van der Waals Volume, dipole moment, E HOMO , E LUMO , charge of N atom in the triazole, logP were used to construct BP network, which predicted the activity with satisfactory results.
