Larotinib mesylate drate is a potent broad-spectrum and orally active tyrosine kinase inhibitor (TKI) with EGFR as the main target with an IC50 of 0.6 nM[1].
每日给 Larotinib mesylate drate 后,SD 大鼠无不良反应水平 (NOAEL) 为 10 mg/kg, 比格犬最低不良反应水平 (LOAEL) 为 5 mg/kg。最大耐受剂量 (MTDs) 在 SD 大鼠和比格犬中分别为 20 和 25 mg/kg[1]。
Larotinib mesylate drate 显示出剂量依赖性的抗肿瘤结果,在肿瘤小鼠模型中,18 mg/kg 肿瘤抑制率超过 60% (数据未发表)[1]。
