ABSTRACT:
Cytochromes P450 (CYP450) inhibitors are compounds that inhibit CYP450 enzyme activity. CYP450 inhibitors can be used to manipulate the metabolism of certain drugs to achieve desired therapeutic. Flavonoids, including alpha-flavones, are known to have a wide range of biological activities and are of interest as potential therapeutics for various diseases. Several chemicals have been synthesized from the alpha-flavone scaffold that has been found to have inhibitory effects on the CYP450-1A1 enzyme system. Therefore, synthesizing chemicals from the alpha flavone scaffold and studying their inhibitory effects on the CYP450-1A1 enzyme system can lead to the discovery of drug candidates that selectively inhibit certain CYP450-1A1 enzymes. Quantitative Structure-Activity Relationship (QSAR) and molecular docking can be used to predict the IC50 of CYP450-1A1 inhibitors. The pIC50 mean value of 323 compounds known as CYP450 inhibitors were used as training datasets. The 30 alpha-naphthoflavone analogs built from the alpha-naphthoflavone scaffold were studied for their inhibition activity using linear and nonlinear regression. Among 30 compounds, 19 compounds potentially have CYP450-1A1 inhibition activity. Among 19 predicted active compounds, three compounds have IC50 below 50 nM. The QSAR regression models predict IC50 of 10-bromo-1-phenyl-phenanthrene (compound 0), 1-phenylthioxanthen-9-one (compound 6), and 2-bromo-1-phenyl-phenanthrene (compound 29) which were 36.9173, 44.8891, 36.9173 nM. The binding energies between these three compounds with chains A, B, C, and D of CYP450-1A1 were below -10 kc/mol. Thus, the interactions between these three compounds with CYP450-1A1 were significant. Consideration from QSAR and molecular docking results might be relevant in the optimization of alpha-naphthoflavone analogs' potential as CYP450-1A1 inhibitors.
