Erlotinib HCl 是一种EGFR抑制剂，在无细胞试验中IC50为2 nM，对EGFR的选择性比对人c-Src或v-Abl高1000多倍。
| CAS No. | 183319-69-9 |
| 生物活性 | Erlotinib Hydrochloride (CP-358774 Hydrochloride) inhibits purified EGFR kinase with an IC50 of 2 nM. |
| 分子式 | C22H24ClN3O4 |
| 分子量 | 429.9 |
| 储存条件 | Powder -20°C 3 years 4°C 2 years In solvent -80°C 6 months -20°C 1 month |
| 溶解性数据 | DMSO :3.33 mg/mL (7.75 mM; ultrasonic and warming and heat to 60°C) H2O : < 0.1 mg/mL (insoluble) |
| 体内研究 | There is a 1.49-fold statistically significant difference between AUC0-inf after p.o. administration of Erlotinib (5 mg/kg) comparing Bcrp1/Mdr1a/1b and WT mice (7,419±1,720 versus 4,957±1,735 ng*h/mL respectively, P=0.01). The administration of Erlotinib (10 mg/kg/day, or 20 mg/kg/day) to Bleomycin (BLM)-treated rats shows no exacerbation of lung injuries in indices such as macroscopic findings, lung weights, histopathological scores (lung lesion density and lung fibrosis score), and pulmonary hydroxyproline (HyP) level. The result suggests that Erlotinib does not have any exacerbating effects on lung injuries induced by BLM in rats. |
| 体外研究 | Erlotinib Hydrochloride (CP-358774 Hydrochloride) is also a potent inhibitor of the recombinant intracellular (kinase) domain of the EGFR, with an IC50 of 1 nM. The proliferation of DiFi cells is strongly inhibited by Erlotinib with an IC50 of 100 nM for an 8-day proliferation assay. The combination of B-DIM and Erlotinib (2 μM) results in a significant inhibition of colony formation in BxPC-3 cells when compared with either agent alone. The combination of B-DIM and Erlotinib (2 μM) results in a significant induction of apoptosis only in BxPC-3 cells when compare with the apoptotic effect of either agent alone. |
