AZD8931 (Sapitinib)是一种可逆的，ATP竞争性EGFR， ErbB2和ErbB3抑制剂，IC50分别为4 nM， 3 nM和4 nM，作用于NSCLC细胞比Gefitinib或Lapatinib更有效，作用于ErbB家族比作用于MNK1和Flt选择性强100倍。AZD8931作用于NSCLC和SCCHN 细胞系的效果不同。AZD8931高度选择性作用于 PC-9细胞(EGFR 激活突变型),GI50为0.1 nM，而低活性作用于 NCI-1437细胞，GI50 >10 μM。与lapatinib 或 gefitinib相比，AZD8931作用于 PE/CA-PJ41, PE/CA-PJ49, DOK 和FaDu细胞，更有效作用于p-EGFR, p-erbB2 和 p-erbB3。

AZD8931 shows different potency to NSCLC and SCCHN cell lines. AZD8931 has high sensitivity to PC-9 cells (EGFR activating mutation) with GI50 of 0.1 nM and low activity to NCI-1437 cells with GI50 above 10 μM. AZD8931 exhibits more potency against phospho-EGFR, phospho-erbB2 and phospho-erbB3 than either lapatinib or gefitinib in PE/CA-PJ41, PE/CA-PJ49, DOK and FaDu cells.

AZD8931 reveals antitumor activity in BT474c, Calu-3, LoVo, FaDu and PC-9 xenografts. AZD8931 could reduce p-Akt, Ki67 expression and p-ERK in BT474c xenografts following acute treatment. AZD8931 also causes induction of the M30 apoptosis marker. Furthermore, AZD8931 shows greater proapoptotic effect compared with gefitinib and lapatinib in LoVo xenografts.
