gls1 inhibitor

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.

GLS1 Inhibitor-3 (compound C147) is a potent GLS1 inhibitor (IC50: 27.98 nM) with anti-proliferative effects.

GLS1 Inhibitor-5 (compound 24y) is a selective, orally active glutaminase 1 (GLS1) inhibitor (IC50: 68 nM) that induces apoptosis and exhibits anti-tumor effects.

GLS1 Inhibitor-4 (compound 41e) is a potent GLS1 inhibitor with an IC50 of 11.86 nM, exhibiting antiproliferative effects, substantial metabolic stability, and strong GLS1 binding affinity. It disrupts glutamine metabolism, induces ROS production, triggers apoptosis, and demonstrates notable antitumor activity [1].

GLS1 Inhibitor-6 inhibitor ( IC 50 =68 nM), shows 220-fold selectivity for GLS2. GLS1 Inhibitor-6 shows good anti-tumor activity, antitumor cell proliferation activity and induces apoptosis .

GLS1 Inhibitor-7 (compound 4d) is a GLS1 antagonist with an IC50 value of 46.7 μM, showing potential applications in anticancer, antiaging, and antiobesity therapies [1].

IPN60090 is a novel, potent, orally bioavailable, renal-type glutaminase (GLS1)-specific inhibitor with an IC50 value of 31 nM for GLS1. IPN60090 has potential anticancer and immunostimulant/immunomodulatory activity, selectively targets, binds, and inhibits human glutaminase, and can be used to study GLS1-mediated diseases.

Purinostat is a selective inhibitor of HDACI/IIb with potential anti-leukemic properties. Its mesylate form, Purinostat mesylate, is effective at inhibiting the survival of Ph+ leukemic cells and CD34+ leukemic cells derived from CML patients. Purinostat mesylate targets HDACI/IIb, impacting several crucial factors for leukemia stem cell (LSC) survival, such as c-Myc, β-Catenin, E2f, Ezh2, Alox5, and mTOR. Additionally, Purinostat mesylate enhances glutamate metabolism in LSCs by increasing GLS1.

Glutaminase-IN-3 is a potent Glutaminase 1 inhibitor with potential antitumor activity and inhibits GLS1 for cancer research.

Telaglenastat (CB-839) hydrochloride is a first-in-class, reversible, and orally active inhibitor of glutaminase 1 (GLS1), selectively inhibiting the splice variants KGA (kidney-type glutaminase) and GAC (glutaminase C), as opposed to GLS2. Telaglenastat hydrochloride has an IC50 of 23 nM for endogenous glutaminase in mouse kidney and 28 nM in the brain, inducing autophagy and exhibiting 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.

Glutaminase C-IN-1 (Compound 968) is an allosteric inhibitor of Glutaminase C (GLS1).

BPTES(IC50 of 0.16 μM) is an effective and specific GlutamiN/Ase GLS1 (KGA) inhibitor.

Telaglenastat (CB 839) (IC50 of 24 nM), an effective, specific, and oral inhibitor, which is bioavailable glutaminase, for recombinant human GAC.

LWG-301, an allosteric inhibitor of Glutaminase 1 (GLS1), demonstrates a potent inhibition with an IC50 value of 7 nM. It effectively impedes glutamine metabolism and elevates intracellular ROS levels, thereby inducing apoptosis. Additionally, LWG-301 shows moderate antitumor efficacy in the HCT116 xenograft model.
