产品介绍
EGF816 (EGF816) 是一种共价突变选择性 EGFR 抑制剂,对 EGFR(L858R/790M) 突变体的 Ki 和 Kinact 分别为 31 nM 和 0.222 min-1。

Cell lines

H3255, HCC827 and H1975 cells

Preparation method

This compound is soluble in DMSO. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 ℃ for several months.

Reacting condition

0.01 nM ~ 100 μM; 3 hrs

Applications

In H3255, HCC827 and H1975 cells, EGF816 significantly lowered pEGFR levels with EC50 values of 5, 1 and 3 nM, respectively. In addition, EGF816 inhibited proliferation of H3255, HCC827 and H1975 cells with EC50 values of 9, 11 and 25 nM, respectively.

Animal models

H1975 mouse xenograft models

Dosage form

3, 10, 30 or 100 mg/kg; p.o.; q.d., for 14 days

Applications

In H1975 mouse xenograft models, EGF816 (10 mg/kg) significantly inhibited tumor growth with a T/C value of 29%. At higher doses of 30 and 100 mg/kg, EGF816 inhibited tumor growth with T/C values reaching ~ 60% and ~ 80%, respectively.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

产品描述

Non-small cell lung cancer (NSCLC) patients with activating epidermal growth factor receptor (EGFR) mutations respond to EGFR tyrosine kinase inhibitors (TKI) but ultimately develop resistance to these therapies. The most common resistance mechanism is a second site gate-keeper mutation within exon 20 of EGFR (T790M). EGF816 is identified as a novel covalent inhibitor of mutant-selective epidermal growth factor receptor.

In vitro: EGF816 showed sustained inhibition of pEGFR, which is consistent with the irreversible binding mechanism of EGF816. EGF816 also performs exceptionally well in long term dosing studies providing durable responses in the preclinical models [1].

In vivo: EGF816 demonstrated strong in vivo tumor regressions in several EGFR activating and resistant tumor models. In all of the models EGF816 inhibited tumor growth dose-dependently and achieved regressions of established tumors at well tolerated doses [1].

Clinical trial: A phase I/II study of EGFRmut-TKI EGF816 is being conducted to investigate the efficacy in adult patients with EGFRmut solid malignancies.
