Glutaminase C inhibitor 11是一种glutaminase C (GAC)的抑制剂。它能够抑制GAC酶的活性(EC50 = 10.64 nM),降低A549非小细胞肺癌(NSCLC)细胞的活力(IC50 = 4.025 nM)。在A549细胞中,Glutaminase C inhibitor 11(0.1和1 µM)能减少细胞集落形成并降低细胞内谷氨酸水平。在体内,Glutaminase C inhibitor 11(100 mg/kg)能够减缓A549小鼠异位瘤模型中的肿瘤生长。
JHU-083 is a selective glutaminase antagonist. JHU-083 blocks glutaminase activity in brain CD11b+ cells. JHU-083 also experimental cerebral malaria (ECM) resulting in a net decrease of glutamate levels in the animals.
GLS1 inhibitor is an inhibitor of glutaminase 1 (GLS1; IC50= 0.021 μM).1It inhibits the growth of NCI H1703 non-small cell lung cancer (NSCLC) cellsin vitro(GI50= 0.011 μM). GLS1 inhibitor (100 mg/kg) reduces tumor growth, increases tumor levels of glutamine, and decreases tumor levels of glutamate and aspartate in an NCI H1703 mouse xenograft model. 1.Finlay, M.R.V., Anderton, M., Bailey, A., et al.Discovery of a thiadiazole-pyridazine-based allosteric glutaminase 1 inhibitor series that demonstrates oral bioavailability and activity in tumor xenograft modelsJ.

Telaglenastat (CB-839) hydrochloride is a first-in-class, reversible, and orally active inhibitor of glutaminase 1 (GLS1). It selectively inhibits the splice variants of GLS1, specifically KGA (kidney-type glutaminase) and GAC (glutaminase C), as compared to GLS2. Telaglenastat hydrochloride has an IC50 of 23 nM for endogenous glutaminase in mouse kidney and 28 nM in the brain. In addition, it induces autophagy and exhibits antitumor activity.
IPN-60090 dihydrochloride is a potent and specific inhibitor of glutaminase 1 (GLS1) with a remarkable inhibition constant (IC50) of 31 nM. It does not exhibit any inhibitory activity against GLS-2. Furthermore, IPN-60090 dihydrochloride possesses outstanding physicochemical properties and pharmacokinetic characteristics in vivo. Therefore, it is a valuable compound for researching solid tumors, including lung and ovarian cancers.
