CONCLUSION Tangeretin was screened against C0X-2 which includes Molecular Docking, DFT analysis, ADMET prediction, and Molecular Dynamics simulation. Tangeretin had good docking scores, fulfill the pharmacological properties through ADMET prediction, and the Protein-Ligand complex had good stability in Molecular Dynamics simulation.

But, it is very difficult to predict this value of a new compound without experiment. There are only a few QSAR based methods available for IC50 prediction which is also highly dependable on huge number of known data. Thus, there is an immense demand for a sophisticated computational method of IC50 prediction, in the field of in-silico drug designing. OBJECTIVE Recently developed quantum computation based method of IC50 prediction by Bag and Ghorai requires an affordable known data. In present research work further development of this method is carried out such that the requisite number of known data being minimal. METHODS To retrench the cardinal data span and shrink the effects of variant biological parameters on the computed value of IC50, a relative approach of IC50 computation is pursued in the present method. To predict an approximate value of IC50 of a small molecule, only the IC50 of a similar kind of molecule is required for this method. RESULTS The present method of IC50 computation is tested for both organic and organometallic compounds as HIV-1 capsid A inhibitor and cancer drugs. Computed results match very well with the experiment. CONCLUSION This method is easily applicable to both organic and organometallic com- pounds with acceptable accuracy. Since this method requires
