4-methyl Erlotinib is an analog of erlotinib by the addition of a methyl group at the four position of the phenyl group. Erlotinib is a tyrosine kinase inhibitor which acts on the epidermal growth factor receptor (EGFR) [1].
The epidermal growth factor receptor (EGFR) autocrine pathway has been important for cancer development and progression, including cell proliferation, apoptosis, angiogenesis, and metastatic spread [2].
Erlotinib inhibits EGFR-associated kinase activity by binding to the EGF-activated receptor, with the phenyl group at one end sequestered in a hydrophobic pocket of the kinase domain and the ether linkages at the opposite end projecting into solvent [1].
Erlotinib can prolong survival in patients with non–small-cell lung cancer after first-line or second-line chemotherapy [3].

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
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。
