ABSTRACT

Rayalu DJ, Rao DM, Seshapani P., In silico docking inhibition of p-glycoprotein by flavonoids, Onl J Bioinform., 22 (2): 121-135, 2021. Flavonoids are found in fruit, vegetables and plants. We describe In silico docking of flavonoids with P-glycoprotein (P-gp) involved in multidrug resistance (MDR). Homology modeling of human P-gp was done with crystal structure of 2HYD chain A multidrug ABC transporter by Modeller. Final model was refined by procheck and verify 3D graph programs subjected to flexible docking P-gp with flavonoids. We found that THR37, ALA42, ARG40 and ARG47 in P- gp had strong hydrogen bonding with Flavonoids and stability. Amongst 10 Flavonoids, Fistein showed optimal docking with P-gp.

Key words: Docking, Flavonoids, Homology Modelling, Molecular Dynamics and P-Glycoprotein.
