A novel view of modelling interactions between synthetic and biological polymers via docking.

abstract：:An empirical hydrophobic field-like 3D function has been calculated with the program HINT (hydrophobic interactions) and imported into the SYBYL implementation of CoMFA (Comparative Molecular Field Analysis). The addition of hydrophobicity appears to offer increased chemical interpretability of CoMFA models. An exampl...
