Data Sheet 产品使用指南

Telaglenastat (CB-839) 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 抑制 GLS1 剪接变异体 KGA 和 GAC，比 GLS2 具有更高的选择性。Telaglenastat 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 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) is a first-in-class, selective, reversible and orally active glutaminase 1 (GLS1) inhibitor. Telaglenastat selectively inhibits GLS1 splice variants KGA (kidney-type glutaminase) and GAC (glutaminase C) compared to GLS2. The IC₅₀s are 23 nM and 28 nM for endogenous glutaminase in mouse kidney and brain, respectively. Telaglenastat inudces autophagy and has antitumor activity.

体外研究

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.
Telaglenastat (CB-839) (1 μM; 72 hours) activates caspase 3/7 and induces apoptosis in MDA-MB-231 and HCC1806 cells.

Cell Proliferation Assay

Cell Line:	HCC1806, MDA-MB-231 cells
Concentration:	0.1, 1, 10, 100, 1000 nM
Incubation Time:	72 hours
Result:	Has a potent effect on the proliferation of the two TNBC cell lines (IC₅₀ of 49 nM and 26 nM for HCC1806 and MDA-MB-231 cells).

Apoptosis Analysis

Cell Line:	MDA-MB-231, HCC1806 cells
Concentration:	1 μM
Incubation Time:	72 hours
Result:	Caspase 3/7 activation.

体内研究

Telaglenastat (CB-839) (200 mg/kg; p.o.; twice daily for 28 days) has antitumor activity in xenograft models of TNBC.

Animal Model:	Female nu/nu mice with age 4–6 weeks (TNBC patient-derived xenograft model)
Dosage:	200 mg/kg
Administration:	Oral administration; twice daily for 28 days
Result:	Suppressed tumor growth by 61% relative to vehicle control at the end of study.
