XL647 is a multi-kinase inhibitor (IC50s = 0.3, 16, 1.5, 8.7, and 1.4 nM for EGFR, ErbB2, KDR, FLT4, and EphB4, respectively).1 It is selective for these kinases over a panel of 10 tyrosine kinases and 55 serine/threonine kinases at 10 μM. XL647 inhibits growth of A431 cells expressing wild-type EGFR and H1975 non-small cell lung cancer (NSCLC) cells expressing both the activating mutant EGFRL858R and the drug resistance-associated mutant EGFRT790M (IC50s = 13 and 920 nM, respectively). In vivo, XL647 (10, 30, and 100 mg/kg) inhibits tumor growth and EGFR phosphorylation in an H1975 mouse xenograft model in a dose-dependent manner.

Cell experiment: | Growth inhibition of H1975 and A431 cells by increasing concentrations of Tesevatinib (XL-647), gefitinib, or erlotinib is determined by seeding 5000 cells per well in 96-well plates. The following day, cells are washed once with low-serum RPMI 1640 (0.1% fetal bovine serum, 1% nonessential amino acids, and 1% penicillin/streptomycin), after which 90 μL of the low-serum RPMI 1640 are added. Test compounds (Tesevatinib (XL-647)) are diluted to 10 times the test concentrations and 10 μL are added to triplicate wells for a 72-h incubation. Cell viability is determined[1]. |
Animal experiment: | Mice: Tumor-bearing mice are given either Tesevatinib (XL-647), erlotinib, or gefitinib at 100 mg/kg and tumors are harvested 1 to 72 h later. Half an hour before respective time point, EGF (50 μg/mouse) is given via i.v. bolus injection with tumors dissected 30 min later and tumor extracts are prepared by homogenization in 10 volumes of ice-cold lysis buffer. Lysates are clarified by centrifugation and EGFR tyrosine phosphorylation levels are determined by ELISA[1]. |

体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
