AG-1478 is an inhibitor of EGFR which acts on EGF-stimulated Erk1/2 phosphorylation with IC50 value of 10 uM using ovarian cell line Ishikawa [1].
EGFR (epidermal growth factor receptor) belongs to human HER-1 family, which is a cell surface receptor and recognized by EGF-family (epidermal growth factor family). Many studies have shown that EGFR is over-expressed in a variety of solid tumors and its over-expression means bad prognosis for cancer patients [1]. AG1478 works as EGFR kinase inhibitor through blocking EGFR phosphorylation and superoxide anion production [2].
Treating human hepatocellular carcinoma HA22T/VGH cells could reduce its anti-tumor activity compared with control group [3]. When tested with ovarian cancer cell lines CAOV-3 or SKOV-3, EGFR signaling was diminished [4]. When human colorectal SW480 was treated with AG-1478, both EGFR phosphorylation and cell proliferation were reduced [5].
In nu/nu mice model with CAOV-3 cells xenografted, treatment with AG-1478 could diminish EGFR phosphorylation thus limited the growth of tumor [4].
Gong XD, et al. had shown that AG-1478 also could reduce the expression of FOXM1 via FOXO3a using a NSCLC cell lines A549, and the A549 cells showed increased chemosensitivity[6].

Tyrphostin AG-1478, a potent and specific inhibitor of EGFR (Epidermal Growth Factor Receptor) tyrosine kinase, plays a key role in the control of normal cellular growth and abnormal cell proliferation. Tyrphostin AG-1478 shows an enhanced in vitro anti-tumor activity in HA22T/VGH cells when entrapmented into NLC(nanostructured lipid carriers) systems compared to free drug.

Animal experiment [2]:

Animal models

Male C57BL/6 mice aged 8 weeks, male ApoE-/- mice aged 8 weeks

Dosage form

10 mg/kg/day, 8 weeks, oral gavage


Administration of AG1478 significantly reduced myocardial inflammation, fibrosis, apoptosis, and dysfunction in both two obese mouse models.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
