  • The structure-activity relationships (SARs) between a series of phenyl-2,2'-methylenebis(cyclohexane-1,3-dione) analogues (1-22) as substrate molecules and their inhibitory activity against tyrosinase were studied quantitatively using molecular hologram quantitative structure-activity relationships (HQSARs). Based on the results, new compounds with the increased tyrosinase inhibitory activity were designed. In addition, statistically favored E-2 model ($q_2$ = 0.564 & $r_2$ = 0.929) was derived. It is predicted that the activity of the most potent one (P1) of compounds newly designed by the optimized HQSAR E-2 model was $Pred.pI_{50}$ = 5.48 and the predicted inhibitory activity was about 13.4 fold higher than that of the kojic acid used as standard compound.
