ENHANCED BIOAVAILABILITY OF ANTIARTHRITIC DRUGS BY HERBAL INHIBITORS OF P-GLYCOPROTEIN – IN SILICO APPROACH Authors: Roy C , ROY S, GANGULI S AND GHOSH P*
ABSTRACT
Background: P-glycoprotein is an efflux transporter implicated in drug resistance in arthritic
patients. Coadministration of medicinal herbal components as inhibitors may configure the transporter
in favour of the drug, thus curtailing its expulsion. Objective: This study endeavours to analyze the
components of antiarthritic herbs in inhibition of p-glycoprotein receptor thus enhancing the possibility
of retention of coadministered antiarthritic medications in the cell. Methods: Druggability and
pharmacokinetic profile of the compounds were examined. Cluster analysis of p-glycoprotein inhibitors
was performed with ChemMine based on structural similarities and physicochemical properties.
Molecular docking utilizing Discovery Studio, was performed to interpret the maximum binding
affinity between 22 inhibitory compounds and the receptor (6C0V). Results: The docking analyses
revealed that the inhibitors viz., thionuphlutine B (Nuphar pumilum), kihadanin A (Phellodendron
amurense) and kopsamine (Kopsia arborea) bind with -187.15, -150.85 and -126.20 (Kcal/mol) energy,
respectively. Conclusion: Molecular dynamics simulation validated the stability of the receptor-thionuphlutine B complex, which may thus be recognized as the lead compound in augmentation of
drug bioavailability inside the cell, along with its herbal antiarthritic therapeutic efficacy.
