Biological Activity
Telaglenastat (CB-839) is a potent, selective, and orally bioavailable glutaminase inhibitor that targets recombinant human GAC with an IC50 of. It blocks the conversion of glutamine to glutamate within the glutamine metabolism pathway, disrupting downstream tricarboxylic acid cycle intermediate replenishment and energy production. This metabolic inhibition leads to antiproliferative effects, induction of autophagy, and robust antitumor activity in preclinical cancer models. [1]

Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
Pre-aliquoted for Longevity: Solid-state aliquots offer longer shelf life compared to stock solutions.
