Compound 8d exhibited potent dual inhibitory activity against EGFR and BRAFV600E. It induces apoptosis, with high gastrointestinal absorption.
New pyrazolylindolin-2-one linked coumarin derivatives were designed as dual BRAFV600E/VEGFR-2 inhibitors targeting melanoma cells A375. Docking simulation showed various interactions with the binding residues in BRAFV600E and VEGFR-2 active sites.
A series of new pyrazolylquinolin-2-ones were designed and synthesised. The structures of the new compounds were validated by IR, NMR, and elemental analysis. The new compounds were evaluated as antiproliferative agents targeting EGFR and BRAFV600E.
This study reported the development of a novel series of thiazole/1,2,3-triazole hybrids and in vitro anticancer efficacy. Compounds 10c, 10e, 10k, 10m, 10n, and 10o exhibited superior anticancer efficacy, particularly against MCF-7 breast cancer.
Vemurafenib triggers resistance via EGFR feedback upregulation, compound 21c achieves a “vertical blockade” by simultaneously inhibiting EGFR and mutant BRAF.
