Targeting aurora kinase a (AURKA) in cancer: molecular docking and dynamic simulations of potential AURKA inhibitors.

Abstract

The Aurora family of serine/threonine kinases in mammals are key regulators of mitotic progression and are commonly upregulated in human tumors. Since AURKA's increased expression has been linked to cancer, AURKA inhibitors could reduce AURKA expression and function as potent therapeutic drugs. The study's objective was to find and categorize inhibitors with a stronger affinity for AURKA. This study also aimed to identify AURKA's expression profile and prognostic significance across pan-cancers. We looked into therapeutic compounds that were structurally comparable to MK8745 for their potential to selectively inhibit AURKA. We used drug likeliness analysis, MD simulation studies to evaluate the therapeutic possibility of screened MK8745 analogues. AURKA was found to be strongly upregulated in several cancers and is linked to worse overall and relapse-free survival. The Molecular docking and dynamic analysis revealed two new MK8745 analogues to be potent AURKA inhibitors with higher binding affinities and stabilities than MK8745. Furthermore, MK8745 analogues are potential replacements for MK8745 because they have strong binding affinity, which is consistent with MDS results, and have appropriate ADMET properties. Through basic, clinical, and preclinical research, the identification of novel compounds may open the door for their prospective use in the prevention of cancer.
