通過測量抑制肽底物磷酸化的情況而獲得抑制酶活性的IC50值。通過桿狀病毒表達系統(tǒng)純化EGFR 和 ErbB2的細胞外激酶域。在96孔圓底板上進行EGFR和ErbB2反應(yīng)，終體積為45 μL。反應(yīng)混合物含50 mM 4-嗎啉丙磺酸(pH 7.5), 2 mM MnCl2, 10 μM ATP, 1 μCi [γ33P] ATP/每次反應(yīng), 50 μM 肽 A [生物素-(氨基)-EEEEYFELVAKKK-CONH2], 1 mM 二流蘇糖醇，及 1 μL DMSO（含連續(xù)稀釋的Lapatinib，起始濃度為10 μM）。加入指定純化的 1型受體胞內(nèi)域，開始反應(yīng)。加入的酶量為為1 pmol/每組反應(yīng)(20 nM)在23oC下反應(yīng)10分鐘，加入45 μL 0.5%溶于水的磷酸，終止反應(yīng)。終止反應(yīng)混合物(75 μL) 轉(zhuǎn)移到磷酸纖維過濾板上。板過濾，然后使用200 μL 0.5% 磷酸沖洗3次。每孔加入閃爍劑(50 μL) , 在Packard Topcount上測量每組反應(yīng)。通過10點劑量反應(yīng)曲線獲得IC50值。

體內(nèi)研究(In Vivo)
體內(nèi)研究活性 Lapatinib 按~100 mg/kg劑量口服處理，每天兩次，顯著抑制BT474和HN5移植瘤生長，這種作用存在劑量依賴性。[1] 與在體外活性一致，Lapatinib按100-150 mg/kg劑量處理攜帶H1975腫瘤的小鼠，延遲腫瘤生長。[3]
