摘要 通过对点价的修正,将分子连接性指数转变成为一种量子拓扑指数。由于改进后的量子 拓朴指数能够很好地表达分子的体积和电性等结构信息,因此该指数与疏水常数计算中的极性基 团相互作用有很好的相关性。实际计算表明,对于含有极性基团的分子,用该指数计算的结果更加 精确。 A novel quantum-topology method was presented, Which can reflect effectively the electronic interaction effect and steric effect in calulation from structure of the hydrophobic parameter, LogP (octanol-water). This makes possible prediction of partition coefficient more accurately from structure.
