Calculation of hydrophobic parameters directly from three-dimensional structures using comparative molecular field analysis.
Capacity ratio (log k') values, which are a measure of hydrophobicity, were calculated directly from the three-dimensional structures of 17 furans and 54 triazines using the comparative molecular field analysis approach. The H2O probe and the GRID force field, including hydrogen-bond potentials, yielded excellent correlations with the log k' values. Moreover, the predicted values of log k' from 14 additional triazine analogs showed excellent agreement with log k' values reported in the literature. Similar results were obtained for the octanol-water partition coefficients (log P) of 17 furans.
