In silico Approach and Molecular Docking Studies of Potent Bioactive Compounds of Carica papaya as Anti-breast Cancer Agents
Abstract
BACKGROUND: Breast cancer is one of the greatest global dilemmas, and the current treatment option is to target hormone receptors with partial agonists/antagonists. Estrogen and aromatase enzymes play important roles in breast cancer. Excessive estrogen activity or inadequate estrogen production leads to various hormonal issues, including breast cancer. Potent breast cancer drugs are Tamoxifen, Paclitaxel, Cyclophosphamide, Trastuzumab, etc., and aromatase inhibitors, include Anastrozole, Letrozole, and Exemestane, etc. In general, breast cancer drugs cause numerous adverse effects in humans.
OBJECTIVES: This study has attempted to identify alternative drug candidates from Carica papaya for treating breast cancer with fewer side effects.
METHODS: To achieve this, we have utilized computational methods to predict the characteristics of bioactive compounds from Carica papaya and determine the target binding affinities using the Schrödinger suite (Maestro 9.5). The target protein and ligands were obtained from the well-known database. Carica papaya has 35 identified bioactive compounds that were drawn using ChemDraw software and performed Ligand preparation wizard. Absorption, Distribution, Metabolism, and Excretion (ADME) analysis is performed with QikProp.
RESULTS: From the docking studies, the phytocompounds such as Chlorogenic acid, Myricetin, Quercetin, Isorhamnetin, and Catechin showed the highest Glide scores (G Score). Among the five bioactive phytocompounds,…
