Affibody (affibody) ligands that are specific for the extracellular domain of human epidermal growth factor receptor 2 (HER2 neu) have been selected by phage display technology from a combinatorial protein library based on the 58 amino acid residue staphy
EGFR HER2-IN-6 (compound 43) is a dual EGFR HER2 and DHFR inhibitor with potent activity against EGFR kinase, HER2 kinase, and DHFR, characterized by IC50 values of 0.122 μM, 0.078 μM, and 0.585 μM, respectively. This compound displays notable anticancer properties in various cancer cell lines, while demonstrating a favorable safety profile and selectivity indices. Consequently, EGFR HER2-IN-6 holds promise as a valuable tool in cancer research [1].
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].
