使用分子力学力场部分原子电荷,我们显示的非唯一性的参数化的连续静电模型的溶质原子半径和内部介电常数的基础上水合(真空到水的转移)的自由能数据可用于小分子。此外,水合自由能计算的最佳和等效的参数集导致计算的绝对和相对静电结合自由能的大的变化。因此,参数化的溶剂化作用的基础上的水合数据,虽然是一个必要的条件,是不足以保证其转移到计算溶液中的结合自由能。© 2003 Wiley Periodicals,Inc. J Comput Chem 24:954-962,2003
Using molecular mechanics force field partial atomic charges, we show the nonuniqueness of the parametrization of continuum electrostatics models with respect to solute atomic radii and interior dielectric constant based on hydration (vacuum‐to‐water transfer) free energy data available for small molecules. Moreover, parameter sets that are optimal and equivalent for hydration free energy calculations lead to large variations of calculated absolute and relative electrostatic binding free energies. Hence, parametrization of solvation effects based on hydration data, although a necessary condition, is not sufficient to guarantee its transferability to the calculation of binding free energies in solution. © 2003 Wiley Periodicals, Inc.
