UK-5099 is a specific and potent mitochondrial pyruvate carrier blocker (MCK blocker). The UK5099 treated cells showed significantly higher proportion of side population (SP) fraction and expressed higher levels of stemness markers Oct3/4 and Nanog. Chemosensitivity examinations revealed that the UK5099 treated cells became more resistant to chemotherapy compared to the non-treated cells. MPC blocker (UK5099) application may be an ideal model for Warburg effect studies

How to use

In Vitro:

The trypanosomal pyruvate carrier is found to be rather insensitive to inhibition by alpha-cyano-4-hydroxycinnamate (Ki=17 mM) but can be completely blocked by UK-5099 (Ki=49 microM). UK-5099 also inhibits the monocarboxylate transporter (MCT) . UK5099 significantly inhibits the glucose-stimulated rise in oxygen consumption in a dose-dependent manner and at 150 μM reduced oxygen consumption below basal levels. UK5099 reduces ATP levels and increases ADP and AMP levels in 832/13 cells. The UK5099 treated cells show significantly higher proportion of side population fraction and express higher levels of stemness markers Oct3/4 and Nanog. UK5099 application may be an ideal model for Warburg effect studies.

In Vivo:

The MPC inhibitor UK5099 increases the glucose excursion seen during an intraperitoneal glucose tolerance test in C57BLK mice.
