产品名称

CB-839 hydrochloride

产品介绍

Telaglenastat (CB-839) hydrochloride 是一种首创的，选择性的，可逆性的，口服活性的谷氨酰胺酶 1 (GLS1) 抑制剂。Telaglenastat hydrochloride 抑制GLS1剪接变异体KGA和GAC，比 GLS2 具有更高的选择性。Telaglenastat hydrochloride 对小鼠类肾和脑中的内源性谷氨酰胺酶的IC₅₀值分别为 23 nM 和 28 nM。Telaglenastat hydrochloride 还可诱导细胞自噬 (autophagy)，并具有强大的抗肿瘤活性。

生物活性

Telaglenastat (CB-839) hydrochloride is a first-in-class, selective, reversible and orally activeglutaminase1 (GLS1)inhibitor. Telaglenastat hydrochloride selectively inhibitsGLS1splice variantsKGA (kidney-type glutaminase)andGAC (glutaminase C)compared to GLS2. TheIC₅₀s are 23 nM and 28 nM for endogenousglutaminasein mouse kidney and brain, respectively. Telaglenastat hydrochloride inudcesautophagyand has antitumor activity^[1].

体外研究
(In Vitro)

Telaglenastat (CB-839) (0.1-1000 nM; 72 hours) has antiproliferative activity in HCC1806 and MDA-MB-231 cells with IC₅₀s of 49 nM and 26 nM, respectively^[1].
Telaglenastat (CB-839) (1 μM; 72 hours) activates caspase 3/7 and induces apoptosis in MDA-MB-231 and HCC1806 cells^[1].
