描述 Lapatinib是有效的 EGFR 和 ErbB2 抑制剂。(Lapatinib is a potent EGFR and ErbB2 inhibitor.)
靶点 EGFR
通路 Angiogenesis;Protein Tyrosine Kinase/RTK; JAK/STAT Signaling
生物活性 Lapatinib (formerly GW572016, trade names Tykerb & Tyverb), usually used in the Ditosylate form, is a potent, orally bioavailable dual EGFR/ErbB2 inhibitor with potential anticancer activity. It inhibits epidermal growth factor receptor (EGFR)/ErbB2 with IC50 of 10.8 and 9.2 nM in cell-free assays, respectively. It is an FDA approved medication used for the treatment of breast cancer and other solid tumors. Lapatinib acts by reversibly blocking the phosphorylation of EGFR, ErbB2, and the Erk-1 and-2 and AKT kinases. [1]
In Vitro Lapatinib (1 μM) induces apoptosis in NCI-N87 and OD19 cells [2]. Lapatinib inhibits the growth of EGFRoverexpressing A431 skin cancer (IC50: 0.14 μM) and ErbB2-overexpressing SK-BR-3 breast cancer cells (IC50:0.124 μM). It also inhibits the growth of ErbB2-amplified OD19 esophageal (IC50: 0.09 μM)and NCI-N87 gastric cancer cells (IC50: 0.01 μM) as well as several types of gastric cancer cells in which ErbB2 is not amplified (IC50s:0.35-8.58 μM) [3] .
In Vivo Lapatinib (100 mg/kg/day, p.o.) induces severe oxidative damage in the cardiac tissue of rat [4].Lapatinib ( 30 and 100 mg/kg, p.o., b.i.d) dose-responsive inhibited the growth of BT474 and HN5 human tumor xenografts. Complete inhibition of tumor growth is seen at the 100 mg/kg dose. At this dose, there is <10% weight loss in treated animals over the course of the 21-day treatment. Lapatinib treatment inhibits tumor xenograft growth of the HN5 and BT474 cells in a dose-responsive manner at 30 and 100 mg/kg orally, twice daily, with complete inhibition of tumor growth at the higher dose [5].
