The implications for the ability of quantum chemical descriptors of highest occupied molecular orbital energy, lowest unoccupied molecular orbital energy, electron affinity ionization potential absolute hardness, Softness , Chemical Potential Molar refractivity (MR), Molar Volume (MV)and Parachor (Pc) to describe the biological activities HIV-1 Protease (RP) Inhibitors of Cycloalkylpyranone derivatives are discussed. The relationships between observed biological activity, log1/C, and the quantum chemical descriptors are established. For this establishment various QSAR models have been developed. The parameter adopted in this calculation is the semi-empirical PM3 based. The QSAR model sixth provides a good arrangement between Obs log 1/c & predicted activity.
