生物活性
描述 Human epidermal growth factor receptor (EGFR; HER1,erbB1), human epidermal growth factor r eceptor 2 (HER2; erbB2), HER3 (erbB3) and HER4 (erbB4) are members of the ErbB family of transmembrane receptor tyrosine kinases. Among them, HER2 is a validated and high-value target. Approximately 30% of breast cancers have an amplification of the HER2/neu gene or overexpression of its protein product, HER2. Also, overexpression of HER2 occurs in gastric, colorectal, NSCLC and ovarian cancers. CP-724714 is a potent inhibitor of HER2 with IC50 value of 10nM (measured by kinase activity), ~640-fold selectivity for HER2 than the closely related kinase EGFR. NIH 3T3 cells transfected with chimeric EGFR/HER2 exposure to CP-724714>250nM showed decrease of EGF-induced autophosphorylation level of HER2. Colony formation was reduced by >80% by CP-724714 at concentration of 1μM in BT-474 cells and at 3μM in SKBR3 cells. Accumulation in G1 phase and a marked reduction in S-phase can be observed in BT-474 cells treated with 1μM CP-724714 for 24h. Oral administration of CP-724714 at dose ranging in 6.25-100mg/kg, q.d., resulted in dose-dependent inhibition of FRE-erbB2 xenografts and 50% tumor growth inhibition at 50mg/kg. Tumor growth inhibition by 41%, 42%, 81% and 100% achieved by 1, 10, 30, and 100 mg/kg CP-724714 in BT-474 xenografts. Also, the tumor growth inhibition of MDA-MB-453 xenografts by 19%, 66%, and 83% was achieved in the 25, 50 and 100 mg/kg b.i.d. treatment groups, respectively. Meanwhile, the reduction ranging in 69%-79% of HER2 phosphorylation in these groups treated with CP-724714 can be observed. Also, treatment with CP-724714 at 30mg/kg or 100mg/kg resulted in significant reduction of p-ERK and p-ATK, the downstreams activated by HER2, in BT-474 xenografts[1].
