摘    要:基于表征生物降解性的原子点价(gi)构建新的自相关拓扑指数(mG),其中的1G不仅对取代芳烃呈现良好的结构选择性,而且与10种取代苯甲酸一级生物降解速率常数(-lgK)显著相关:-lgK=0.591 6 0.005 01G,R2=0.966 4。引入0G:-lgK=0.773 8-0.008 30G 0.006 31G,R2=0.977 5。结果表明,该方法具有物理意义明确,计算简单等优点。

关 键 词:原子点价  自相关拓扑指数  取代苯甲酸  生物降解性  速率常数  定量结构-生物降解相关性

Abstract:Based on the atomic point valence(g_i) of biodegradability,a novel autocorrelation topological index(()~mG) is derived in this paper.Among ()~mG,()~1G has shown good structure selectivity for substituted aromatic compounds,and an apparent correlation for the first order biodegradation dynamic constants of 10 substituted benzoic acids is established as:-lgK= 0.591?6 0.0050()~1G,R~2 = 0.966?4.A satisfactory equation is developed as following:-lgK= 0.773?8-0.008?3()~0G 0.006?3()~1G,R~2=0.977?5.It has been demonstrated that the method is clear in physical meaning and easy to compute.
Keywords:Atomic point valence  Autocorrelation topological index  Substituted benzoic acid  Biodegradability  Dynamic constant  Quantitative structure-biodegradability relationship
