Abstract

Some thermophysical parameters of CBD and THC such as free energy, entropy, dipole moment, binding energy, nuclear energy, electronics energy, heat of formation, and chemical reactivity like HOMO (Occupied Molecular Orbital Highest) and LUMO (Lowest Unoccupied Molecular Orbital, HUMO-LUMO gap, ionization potential and electron affinity were calculated via semi-empirical and molecular mechanic method. For the characterization, the IR vibration spectroscopy, NMR in case of coupling and shielding constant were calculated. The Quantitative Structure Activity Relation (QSAR) properties of molecules like charge density, surface area grid, volume, LogP, polarizability, refractivity, molecular mass were determined using the HyperChem 8.0.10 program. Using the thermophysical and QSAR data, the IC50 and pHIC50 (–logIC50) was developed which is referred as biological activity parameter.
