The MOLE db – Molecular Descriptors Data Base is a free on-line database constituted of 1124 molecular descriptors calculated on 234773 molecules, released by Milano chemometrics and QSAR research group. This data base is intended as a research and teaching tool and basically allows the researcher to: a) search for a specific group of molecules and analyse the corresponding values of molecular descriptors b) save in an output file the values of a block of molecular descriptors calculated on a group of molecules.
