Erlotinib Hydrochloride

产品活性：Erlotinib Hydrochloride (CP-358774 Hydrochloride) 抑制 EGFR 激酶的 IC₅₀ 为 2 nM。Erlotinib (Hydrochloride) 是一种点击化学试剂。它含有 Alkyne 基团，可以和含有 Azide 基团的分子发生铜催化的叠氮-炔环加成反应 (CuAAc)。

研究领域：JAK/STAT Signaling | Protein Tyrosine Kinase/RTK | Autophagy

作用靶点：EGFR | Autophagy

In Vitro: 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.

In Vivo: There is a 1.49-fold statistically significant difference between AUC_0-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.
