| Description | AC480 (BMS-599626) is a selective and efficacious inhibitor of HER1 and HER2 with IC50 of 20 nM and 30 nM, ~8-fold less potent to HER4, >100-fold to VEGFR2, c-Kit, Lck, MET etc.
IC50 value: 20 nM (HER1); 30 nM (HER2) [1]
Target: HER1/HER2
in vitro: BMS-599626 inhibited HER1 and HER2 with IC50 of 20 and 30 nmol/L, respectively, and was highly selective when tested against a broad panel of diverse protein kinases. Biochemical studies suggested that BMS-599626 inhibited HER1 and HER2 through distinct mechanisms. BMS-599626 abrogated HER1 and HER2 signaling and inhibited the proliferation of tumor cell lines that are dependent on these receptors, with IC50 in the range of 0.24 to 1 micromol/L. BMS-599626 was highly selective for tumor cells that depend on HER1/HER2 and had no effect on the proliferation of cell lines that do not express these receptors. In tumor cells that are capable of forming HER1/HER2 heterodimers, BMS-599626 inhibited heterodimerization and downstream signaling [1]. At the molecular level, in HN-5 cells the agent inhibited the expression of pEGFR, pHER2, cyclins D and E, pRb, pAkt, pMAPK, pCDK1 and 2, CDK 6, and Ku70 proteins. The drug also induced accumulation of cells in the G1 cell cycle phase, inhibited cell growth, enhanced radiosensitivity, and prolonged the presence of γ-H?AX foci up to 24 h after radiation [2].
in vivo: BMS-599626 had antitumor activity in models that overexpress HER1 (GEO), as well as in models that have HER2 gene amplification (KPL4) or overexpression (Sal2), and there was good correlation between the inhibition of receptor signaling and antitumor activity [1]. The drug given before and during irradiation improved the radioresponse of HN5 tumors in vivo [2]. References: | |||||

BMS-599626 is a selective inhibitor of HER1 and HER2 with IC50 value of 22 nM and 32 nM, respectively [1].
HER (human epidermal growth factor receptor) is a member of EGFR/ErbB family and plays an important role in transduction of cell proliferation and differentiation. It has been reported that abbrent expression of HER is correlated with cancer and HER inhibition is being regarded as a promising strategy for cancer treatment [1].
BMS-599626 is a potent HER inhibitor and has the higher inhibition ability than the other reported inhibitors. When tested with breast tumor cell lines (HCC202, HCC1942 and AU565) that highly expressing HER1 and HER2, BMS-599626 treatment inhibited cell proliferation, while had no effect on A2780 cells that without HER1 or HER2 expression [1]. Treated OV202 cells with BMS-599626 significantly inhibited cell proliferation and enhanced cell apoptosis by inhibiting HER [2].
In mouse model with Sal2 tumor cells xenograft, oral administration of BMS-599626 inhibited Sal2 cells growth in a dose-dependent manner and significantly delayed tumor growth at the concentration of 60 mg/kg [1].
When tested with Sal2 cells expressing CD8-HER2 fusion protein, BMS-599626 treatment inhibited the receptor phosphorylation and MAPK phosphorylation with the IC50 value of 0.3 and 0.22 μM/L, respectively [1].

Small molecules with EGFR-TK inhibitor activity.[Pubmed:15857287]
Curr Drug Targets. 2005 May;6(3):259-74.
Specific and reversible EGFR tyrosine kinase inhibitors (TKI) such as gefitinib and erlotinib are clinically active in advanced or metastatic NSCLC and both are approved in various countries for the treatment of patients that failed prior chemotherapy. Erlotinib has also prolonged survival in pancreatic cancer patients when added to gemcitabine and regulatory approval in this disease is being sought. Additional promising activity has been seen in other tumor types, such as ovarian cancer or head and neck malignancies, and phase III trials in these malignancies are ongoing or planned. Despite these successes, these agents have exhibited anecdotal or modest activity when used as single agents in unselected patients with various other tumor types. We have learned that the clinical development of these agents is far from simple and we need to better understand biological and clinical criteria for patient selection and how to best use the different available agents. The recent discovery of EGFR mutations and the potential identification of other markers that might predict patient response could help to optimize the use of these agents in the future. Irreversible EGFR inhibitors, dual EGF/HER2 and pan-ErbB receptor inhibitors may have greater antitumor activity although the tolerance of these compounds compared to specific EGFR TKIs needs further characterization. HER2 specific TKIs are also in development. Lapatinib, a dual EGFR/HER2 TK inhibitors, is particularly promising in breast cancer. Newer agents, such as BMS-599626, have recently entered into the clinic. In addition to the use of these agents as single agents, many clinical studies are addressing the role of combining them with hormonal agents, biological agents or chemotherapy.
