Özet

Permeability-glycoprotein (P-gp), a dynamic efflux pump responsible for transporting xenobiotics and drugs out of cells, is a contributor to multidrug resistance (MDR), a pervasive challenge in therapeutic efficacy. In Hepatocellular Carcinoma (HCC), chemotherapy failures are often attributed to both multi-drug resistance and mounting evidence spotlighting the multi-drug resistance protein-1 (MDR1, also recognized as P-gp) as a pivotal determinant of chemotherapy resistance in HCC. Aligned with the FDA’s 2020 directives, the investigation of P-gp inhibition has been mandated for Drug-Drug Interaction (DDI) assessments, hepatotoxicity evaluations, and therapeutic contexts. Yet, a prevalent experimental technique poses a hurdle. The FDA-endorsed MDCK-MDR1 cell-based permeability assay, while valuable for discerning and characterizing P-gp inhibitors, grapples with limited throughput and high expenses, amounting to ~10,000 € per compound. In response to these challenges, we introduce a pioneering approach that harnesses molecular docking to uncover potential natural inhibitors of the P-gp liver transporter. Our molecular docking outcomes unearth profound insights. Noteworthy reference drugs, Elacridar (−10.70 kcal/mol) and Zosuquidar (−10.50 kcal/mol), exhibit substantial affinities. Furthermore, our inquiry pinpoints a cluster of natural compounds boasting robust affinities against P-gp, with projections as potential inhibitors with binding energies of ~10.50 kcal/mol. Our in-silico methodology navigates the domain of natural P-gp inhibitors, furnishing an extensive comprehension of intricate interactions between inhibitor compounds and P-gp protein. This innovative approach holds the promise of a cost-effective substitute for prevailing screening methods. It could potentially pave the path toward devising efficacious strategies combating P-gp-driven MDR in the realm of HCC therapy.
