Emvododstat (PTC299)

Emvododstat(PTC299), a post-transcriptional inhibitor of pathogenic VEGF and dihydroorotate dehydrogenase(DHODH), inhibits VEGFA mRNA translation and abnormal cell proliferation. In HeLa cells PTC299 inhibits hypoxia-induced VEGFA protein production with an EC50 of 1.64 nM.

Biological Activity

Description Emvododstat(PTC299), a post-transcriptional inhibitor of pathogenic VEGF and dihydroorotate dehydrogenase(DHODH), inhibits VEGFA mRNA translation and abnormal cell proliferation. In HeLa cells PTC299 inhibits hypoxia-induced VEGFA protein production with an EC50 of 1.64 nM.
Targets
Dihydroorotate dehydrogenase [1] VEGFA [2]
(in hypoxia-induced VEGFA protein inhibition assay of HeLa cells)
1.64 nM(EC50)
In vitro
In vitro

Emvododstat (PTC299) inhibits hypoxia-induced VEGFA protein production in HeLa cells with an EC50 of 1.64 ± 0.83 nM. Emvododstat is the most potent inhibitor with an IC50 of about 1 nM, over 10 to 1000-fold more potent than Brequinar, Vidofludimus or A77-1726 in leukemia cells. The decreased translation of VEGFA mRNA by Emvododstat is linked to the inhibition of de novo pyrimidine nucleotide synthesis as exogenously added uridine, but not other nucleosides, can completely block the inhibition of VEGFA production by Emvododstat.[2]
Cell Research Cell lines HeLa cells, leukemia cells
Concentrations 0.1-1000 nM
Incubation Time 72 h
Method

Cells are treated with Emvododstat at a series of doses for 72 hours. And the inhibition of cell proliferation is determined using a standard assay, CellTiter-Glo Luminescent Cell Viability Assay measures total cellular adenosine triphosphate (ATP) concentrations as an indicator of cell viability.
In Vivo
In vivo

Emvododstat has no adverse off‐target effects and no adverse effects on neurological or cardiopulmonary organ systems in rats and dogs[4].

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.
