Epidermal growth factor receptor (EGFR) is a validated oncogenic driver in numerous solid tumors, and resistance to first- and second-generation tyrosine kinase inhibitors continues to limit clinical outcomes.
This study focused on the development of a novel series of 5-ethylsulfonyl-indazole-3-carboxamides (8a–l) as dual inhibitors of VEGFR-2 and EGFR. Compounds 8g and 8h emerged as the most potent derivatives against breast (MCF-7) and colorectal (HCT-116) cancer cell lines.
A series of derivatives (5–14) were synthesized through the diazotization of sulfadiazine with active methylene compounds.
A series of new dihydropyrimidine/1,2,4-oxadiazole compounds was designed and synthesised. Their structures were validated by IR, NMR, and elemental analysis, and they were evaluated as antiproliferative agents targeting EGFR and VEGFR-2.
A series of pyrimidine-5-carbonitriles was designed and synthesized as potential anti-cancer agents with dual EGFRWT/COX-2 inhibition. Compounds 4e and 4f disclosed the highest activity on all NCI60 cell lines.
