Advances in VEGFR Inhibitors: A Comprehensive Review of Novel Anticancer Agents.

Abstract

Cancer, characterized by aberrant cell growth, presents a formidable health challenge, impacting millions of individuals worldwide each year. Among the myriad mechanisms facilitating tumor progression, Vascular Endothelial Growth Factor receptors (VEGFR) play a pivotal role in driving angiogenesis the process by which tumors develop their own blood supply. This vascularization not only supports tumor nourishment and growth but also facilitates metastasis, enabling cancer to spread to distant sites. VEGFR inhibitors offer a strategic approach to disrupt the VEGF-VEGFR binding pathway, thereby impeding angiogenesis, metastasis, and the proliferation of cancer cells. This review elucidates the latest advancements in medicinal chemistry pertaining to VEGFR inhibitors, showcasing a variety of chemical moieties and assessing their efficacy across different cancer cell lines. The novel compounds highlighted in this review exhibit significant promise for anticancer evaluation through targeted VEGFR kinase inhibition. A robust body of in vivo, in vitro, and ex vivo studies supports these findings, demonstrating the antitumor effects of these compounds. Computational analyses further enhance our understanding by predicting compound binding affinities, pharmacokinetics, and overall drug-likeness. Despite the significant progress made in developing effective VEGFR inhibitors, challenges remain in refining these agents for optimal cancer treatment. This review not only summarizes the advancements achieved in VEGFR inhibitor development but also emphasizes the ongoing hurdles that must be addressed to enhance the efficacy of cancer therapies.
