UK5099 covalently binds to Mpc and blocks pyruvate transport. UK5099 enhances aerobic glycolysis and decreases mitochondrial oxidative phosphorylation in LnCap cell in vitro, which is accompanied by increasing proportion of side population (SP) fraction, higher level of stemness markers expression and exhibiting high resistance to chemotherapy. UK5099 enhances stem-like phenotype of prostatic cancer cell through metabolic shift from oxidative phosphorylation to aerobic glycolysis. UK5099 suppresses proliferation and arrested LnCap cell cycle at G1/G0.
In vivo
UK-5099 slows the growth of patient-derived xenograft (PDX) tumors in mice without severe loss of animal body weight.
