egfr kinase inhibitor 6

EGFR kinase inhibitor 6 (Compound 4b) is an orally active epidermal growth factor receptor (EGFR) kinase inhibitor with an IC50 of 24.34 μM. It induces apoptosis and demonstrates anticancer and anti-inflammatory properties, exhibiting low toxicity with an LD50 range of 500-2000 mg/kg.

AG-494 (Tyrphostin B48) is an inhibitor of epidermal growth factor receptor kinase.

EGFR-IN-110 (Compound 6) is a covalent inhibitor of EGFR, demonstrating pIC50 values of 9.2 for the EGFR enzyme and 8.7 for EGFR cells. It exhibits strong efficacy in targeting EGFR and maintains good kinase selectivity.

Potent EGFR-kinase inhibitor (IC50 = 0.7 nM). Displays >3000-fold selectivity against a panel of serine/threonine kinases. Reduces metastasis and angiogenesis in a mouse model of pancreatic cancer.

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].

HER2-IN-6 is a potent inhibitor of HER2 with potential for investigation in wild and/or mutant EGFR and/or HER2 kinase-mediated tumors.

Antiproliferative Agent-34 (Compound A14), a multitarget kinase inhibitor, demonstrates IC50 values of 177 nM for EGFR L858R/T790M and 1567 nM for EGFR WT. Additionally, it inhibits JAK2, ROS1, FLT3, FLT4, and PDGFRα with respective IC50s of 30.93 nM, 106.90 nM, 108.00 nM, 226.60 nM, and 42.53 nM. In normoxic conditions, it suppresses the proliferation of H1975 and HCC827 cells with IC50 values below 40 nM, while under hypoxic conditions, its potency increases 4-6 fold, yielding IC50 values less than 10 nM [1].

Multi-kinase-IN-6 (compound 10e) is a multikinase inhibitor that impedes the activity of TrkA, ALK2, c-KIT, EGFR, PIM1, CK2α, CHK1, and CDK2. It exhibits antiproliferative effects on MCF7, HCT116, and EKVX cancer cell lines with IC50s of 3.36 μM, 1.40 μM, and 3.49 μM, respectively. Additionally, Multi-kinase-IN-6 induces cell cycle arrest at the G1/S and G1 phases in MCF7 and HCT116 cells, respectively, and effectively triggers apoptosis [1].

Corylifol C is a natural product isolated from Psoralea corylifolia and an effective protein kinase inhibitor with an IC50 value of 1.1×10⁻⁶ μg/ml against EGFR.
