Abstract

The epidermal growth factor receptor (EGFR), a crucial component of cellular signaling pathways, is frequently dysregulated in a range of cancers. EGFR targeting has become a viable approach in the development of anti-cancer medications. This study employs an integrated approach to drug discovery, combining multiple computational methodologies to identify potential EGFR inhibitors.

Introduction

The transmembrane glycoprotein known as epidermal growth factor receptor (EGFR) has an intracellular tyrosine kinase domain in addition to an external EGF binding region. It governs cellular proliferation and signaling pathways [1]. It has been found that EGFR is overexpressed in a variety of cancer cells, including those from the head and neck, breast, esophagus, and lung.

Materials and method

Pharmacophore Modelling

A pharmacophore model can be described as a chemical template that comprises the essential structural features of biologically active compounds. The structural features of an active compound are utilized to generate pharmacophore model which then processed to conduct the screening of large chemical databases [17]. We developed a ligand-based pharmacophore model using the chemical features of a co-crystal ligand (R85) of Epidermal growth factor receptor (PDB ID: 7AEI) by using the Pharmit server [18,19]. 

Results

Pharmacophore modelling and virtual screening

The pharmacophoric features of R85 ligand involved in the molecular interactions with EGFR protein were used to develop the pharmacophore query model (Fig 2A). There was a total of six features which were used to generate the query model (Fig 2B). The X, Y, and Z coordinates of the features are shown in Table 1. 

Discussion

Despite the initial success of EGFR inhibitors, resistance frequently develops over time, limiting their long-term effectiveness. Cancer cells can adapt through a variety of mechanisms, including secondary mutations in the EGFR gene and alternative signaling pathways. To overcome or delay the development of resistance, novel inhibitors with different mechanisms of action are required [16,33].
