空间距离在三维分子相似度计算中的应用

Atom Space Distance and Computing of Molecular Similarity

采用Ｔｒｉｐｏｓ 公司的ＭＯＰＡＣ模块计算分子的空间距离， 所得距离矩阵用带有约束条件的空间距离方法计算分子的相似度， 同时通过４ 组化合物的计算， 与纯空间距离方法进行比较， 得到了较为满意的结果．

A mathematical model on computation of molecular similarity was suggested. The algorithmic techniques for measuring the degree of similarity between pairs of three dimensional chemical molecules was represented by modified interatomic distance matrices. Current work was carried out on Indigo 2 work station with Sybyl software. Four groups of molecules were used to compute the molecules similarity to testing the mathematical model with satisfatory results.
