定量构效关系研究中图论方法:路径长度指数P1与烷烃13C NMR化学位移和CSS
On Graph Theory in QSAR/QSPR: Approach to C - 13 NMR Chemical Shift Sum in Alkanes with Intergater Path Index
【摘要】 系统研究了图论方法在定量构效(性)关系(QSAR/QSPR)中的应用,研究了一种路径长度新的指数P1,并发现它与烷烃13CNMR化学位移和有良好线性相关性。
【Abstract】 Systematic studies were made on graph theory in quantitative structure-activity/property relationships(QSAR/QSPR). Chemical shift sums for C - 13 nuclear magnetic resonance(NMR) in alkanes were well correlated with a novel molecular graph index, P1, called path of length one, as a simple proportional equation with good results:CSS = a + b P1 = (r = 0.9).
