3PO 是一种 PFKFB3 的小分子抑制剂，IC50值为22.9 μM。它抑制几种人类恶性造血和腺癌细胞系的增殖，IC50在1.4到24 μM之间。它抑制葡萄糖摄取，并降低 Fru-2,6-BP、乳酸、ATP、NAD+ 和 NADH 的细胞内浓度。

3PO is a small-molecule inhibitor of PFKFB3 (IC50: 22.9 μM), inhibiting the proliferation of several human malignant hematopoietic and adenocarcinoma cell lines (IC50: 1.4-24 μM). It suppresses glucose uptake, and decreases the intracellular concentration of Fru-2,6-BP, lactate, ATP, NAD+, and NADH.

3PO markedly attenuates the proliferation of several human malignant hematopoietic and adenocarcinoma cell lines (IC50, 1.4-24 μM) and is selectively cytostatic to ras-transformed human bronchial epithelial cells relative to normal human bronchial epithelial cells. Compared with the wild-type PFKFB3+/+transformed cells (IC50, 49 μM), the PFKFB3+/- fibroblasts were more sensitive to compound 3PO treatment (IC50, 26 μM). 3PO Causes G2-M phase arrest, which Is preceded by decreased Fru-2,6-BP and glucose uptake. 3PO slows growth through inhibition of PFK-2 activity, then ectopic expression of the PFKFB3 isozyme may thwart the cytostatic activity of 3PO. [1] 3PO inhibits the glycolytic regulator PFKFB3 in endothelial cells (ECs). 3PO decreases glycolysis in ECs and impairs vessel sprouting. 3PO also suppresses vascular hyperbranching induced by inhibition of Notch or VEGF receptor 1 (VEGFR1) and amplified the antiangiogenic effect of VEGF blockade[2].

Compared with vehicle control, compound 3PO treatment significantly reduced Fru-2,6-BP in tumor xenografts (vehicle: 13.1 ± 1.9 pmol/mg, 3PO: 8.5 ± 1.7 pmol/mg). [1] 3PO also impairs (pathological) angiogenesis.
