(R)-GNE-140 inhibits proliferation in 37 of 347 cancer cell lines tested at a potency cut off of 5 μM. (R)-GNE-140 exhibits inhibition with two chondrosarcoma (bone) cancer cell lines that harbored IDH1 mutations (IC50 = 0.8μM).(R)-GNE-140 has submicromolar MiaPaca2 potency and inhibits proliferation in 11% of cancer cell lines in a broad panel.

Concentrations 6 pt dose titration scheme
Incubation Time 72 h
Method

Cells are plated using optimal seeding densities in 384-well plates using RPMI, 5% FBS, 100 ug/ml penicillin, 100 units/ml streptomycin. Optimal seeding densities are established for each cell line in order to reach 75-80% confluence at the end of the assay. The following day, cells are treated with (R)-GNE-140 using a 6 pt dose titration scheme. After 72 hours, cell viability is assessed using the CellTiter-Glo® Luminescence Cell Viability assay. Absolute inhibitory concentration (IC) values are calculated using four-parameter logistic curve fitting.
In Vivo
In vivo

(R)-GNE-140 presents a low Clp, and also had high bioavailability when dosed orally at 5 mg/kg to mice. At higher oral doses, ranging from 50 to 200 mg/kg, (R)-GNE-140 displays greater in vivo exposure.[1]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
