Earlier we showed (A. K. Ghose and G. M. Crippen, J. Med. Chem., 28, 333, 1985) the necessity of atomic physicochemical parameters in three‐dimensional receptor mapping. Here we derive more refined and widely applicable hydrophobicity parameters. Carbon, hydrogen, oxygen, nitrogen, sulfur, and halogens are classified into 110 atom types. Among these, the hydrophobic contributions of 90 atom types have been evaluated from the log P(water‐octanol) values of 494 molecules, using the additive model…
