2-cyano-3-(1-phenylindol-3-yl)acrylate

UK-5099 (56396-35-1) is a potent inhibitor of the mitochondrial pyruvate carrier (MPC).1Rapidly increases glucose uptake in human monocytes.2Attenuates mitochondrial oxidative phosphorylation and increases glycolysis creating greater stem-like properties in LnCap prostate cancer cells.3Blocks the neuroprotective action of L-lactate or pyruvate during glutamate-induced excitotoxicity.4Inhibits pyruvate transport across the plasma membrane of trypanosomes (Ki=49 μM).5

Yellow Solid

UK-5099 has been used:

• as a mitochondrial pyruvate blocker to reduce pyruvate transportation into mitochondria in Roswell park memorial institute (RPMI) 1640 medium for prostatic cancer cell line culture
• in dimethyl sulfoxide (DMSO) stock, to study the effect of inhibiting pyruvate transport into mitochondria on pro-inflammatory responses in lipopolysaccharide activated macrophages
• in topical treatment in order to study its effect on hair cycle induction in experimental mice

Pyruvate transport into mitochondria is facilitated by mitochondrial pyruvate carrier (MPC) 1 and 2, two small transmembrane proteins that are part of a larger 150 kDa protein transport complex in the inner mitochondrial membrane. UK 5099 is a specific and potent inhibitor of MPC carrier activity. It potently inhibits pyruvate-dependent oxygen consumption by rat heart mitochondria with an IC50 value of 50 nM.

Inhibitor of plasma membrane monocarboxylate transporters (MCTs) and the mitochondrial pyruvate carrier (MPC).

UK-5099 induces lactate generation.
