PFK 15 is a novel inhibitor of glycolytic enzyme 6-phosphofructo-2-kinase/2,6-bisphosphatase 3 (PFKFB3). It suppresses the glucose uptake and growth of Lewis lung carcinomas in syngeneic mice, and induces apoptosis in abnormal cells. | [Biological Activity]
pik-75 is a specific inhibitor of p110α isoform of pi3k with ic50 of 5.8 nm [1].in acute myeloid leukemia cells, pik-75 targeted the p110α isoform of pi3k, which led to a loss of connection between bcl-xl and bak. pik-75 also transiently decreased cdk7/9, leading to loss of mcl-1 protein, and alleviation of its inhibition of pro-apoptotic bak. the simultaneous loss of bcl-xl and mcl-1 led to rapid apoptosis. [2] in human monocyte-endothelial cell, pik-75 suppressed the events of downstream signaling, including akt phosphorylation, ikk activation, and nf-kb transcription. pik-75 inhibited in vitro and in vivo production of tnf-α and il-6, decreased the e-selectin, icam-1, and vcam-1 expression, and blocked cell adhesion [3]. in human smooth muscle cells, pik-75 decreased tnf-α-induced cd38 expression in asthmatic and nonasthmatic cells [4]. in pancreatic β-cells, acute treatment with pik-75 enhanced the glucose-induced insulin secretion [5]. | [in vivo]
pik-75 significantly suppressed the histological abnormalities associated with dextran sulfate sodium-induced murine colitis. pik-75 can attenuate experimental inflammation in the colon [3]. | [target]
