EGFR/HER2-IN-7 is a highly selective and potent anticancer compound specifically designed to target MCF-7 breast cancer cells. It functions as a dual inhibitor, targeting both EGFR/HER2 kinases and DHFR (dihydrofolate reductase). Its inhibitory activities are measured with IC50 values of 0.18 μM for EGFR, 0.146 μM for HER2, and 0.907 μM for DHFR [1].
