A Potent Solution for Tumor Growth and Angiogenesis Suppression Via an ELRCXCL-CXCR1/2 Pathway Inhibitor

Abstract

CXCR1/2 biomolecules play vital roles in cancer cell proliferation, tumor inflammation, and angiogenesis, making them attractive drug targets. In clear cell renal cell carcinoma (RCC) and head and neck squamous cell carcinoma (HNSCC), where CXCR1/2 is overexpressed, inhibition studies are limited. Building upon previous research efforts, we investigated new ,'-diarylurea analogues as ELRCXCL-CXCR1/2 inhibitors. Evaluations on RCC and HNSCC cell lines and 3D spheroid cultures identified compound as a lead molecule, exhibiting significant inhibition of invasion, migration, and neo-angiogenesis. It demonstrated strong interference with the signaling pathway, with high selectivity toward kinases. studies on zebrafish embryos and RCC xenografted mice showed notable anticancer, antimetastatic, and antiangiogenic effects after oral administration and minimal toxicity. Compound emerges as a promising candidate for further preclinical development as an oral anticancer and antiangiogenic drug targeting the ELRCXCL-CXCR1/2 pathway.
