With compounds for drugs, agricultural chemicals, etc., the invention provides a novel method for superposing molecular structures of those compounds. A method for superposing molecular structures of compounds characterized-in that, upon superposing the molecular structures of a plurality of compounds, (1) the characteristic groups (atoms) of compounds are roughly divided into four types of hydrophobicity (aliphatic chain/ring, aromatic ring and halogen), hydrogen-bonding donor, hydrogen-bonding acceptor and hydrogen-bonding donor/acceptor, (2) a molecule of compound with large radius of inertia calculated from constituting characteristic groups (atoms) is fixed, superposition is performed among a set of characteristic groups (atoms) with the same nature between two molecules of compounds, and operations of translation and rotation are performed in its neighborhood, (3) when causing the superposition of characteristic groups (atoms) between molecules of compounds by the operations of translation and rotation in (2), a score is given depending on the combination between respective characteristic groups (atoms), (4) scores of superposition are summed up, and (5) said operations of (2) through (4) are repeated to find out an orientation that acquires the highest score value.
对于药物、农药等化合物,本发明提供了一种用于叠加这些化合物分子结构的新方法。一种叠加化合物分子结构的方法,其特征在于:在叠加多个化合物的分子结构时,(1) 将化合物的特征基团(原子)大致分为疏水性(脂肪族链/环、芳香族环和卤素)、氢键供体、氢键受体和氢键供体/受体四种类型,(2) 固定一个根据特征基团(原子)的构成计算出的惯性半径较大的化合物分子、(3) 通过(2)中的平移和旋转操作使化合物分子之间的特征基团(原子)叠加时,根据各特征基团(原子)之间的组合给出分值,(4) 将叠加的分值相加,(5) 重复(2)至(4)中的操作,找出获得最高分值的取向。
