Mechanism of Action

Information	Telaglenastat (CB-839) is a potent, selective, and orally bioavailable glutaminase 1 (GLS1) inhibitor. It affects ATF4/CHOP, AMPK, and mTOR signaling pathways by blocking glutaminolysis and depleting TCA cycle intermediates, effectively inhibiting cancer cell proliferation and inducing apoptosis.

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration _(start) x Volume _(start) = Concentration _(final) x Volume _(final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).
