5MPN is a first-in-class, potent, orally active and selective 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 4 (PFKFB4) inhibitor. 5MPN appears to be a competitive inhibitor of the F6P binding site (Ki=8.6 μM). 5MPN does not inhibit PFK-1 or PFKFB3. 5MPN targets the sugar metabolism of tumors and suppresses proliferation of multiple human cancer cell lines[1].
5MPN (0~30 μM; 24 hours; H460 cells) inhibits the expression of PFKFB4[1]. 5MPN (0~50 μM; 0~72 hours; H460 NSCLC cells) first reduces the intracellular concentration of F2,6BP, glycolysis and ATP, which in turn results in a reduction in cell proliferation[1].5MPN (0 and 10 μM; 6, 12 and 24 hours; H460 cells) induces cells apoptosis[1].5MPN (0 and 10 μM; 6, 12 and 24 hours; H460 cells) arrests cell cycle progression[1].5MPN (0.1, 1 or 10 µM) significantly inhibits PFKFB4 activity. 5MPN (H460 cells) leads to a dose-dependent decrease in the intracellular F2,6BP concentration. 5MPN (0~30 μM; over 48 hours; H460, H1299, H441, H522 and A549 cells) makes a dose-dependent reduction in cells growth. 5MPN (0~30 μM; 24 hours; H460 cells) inhibits PFKFB4 expression causing the observed reduction in H460 cell proliferation. 5MPN causes a G1 arrest in LLC cells in vitro similar to H460 cells[1].
5MPN (120 mg/kg; p.o.) suppresses the growth of Lewis lung carcinomas (LLC) grown in syngeneic mice and H460 human lung adenocarcinoma xenografts grown in athymic mice without affecting body weight[1].5MPN causes a reduction in Ki67-positive cells in the LLC xenografts suggesting that 5MPN may be reducing cell cycle progression in vivo[1].

CD44ICD promotes breast cancer stemness via PFKFB4-mediated glucose metabolism
Theranostics 2018 Nov 29;8(22):6248-6262.PMID:30613295DOI:10.7150/thno.28721.
CD44 is a single-pass cell surface glycoprotein that is distinguished as the first molecule used to identify cancer stem cells in solid tumors based on its expression. In this regard, the CD44high cell population demonstrates not only the ability to regenerate a heterogeneous tumor, but also the ability to self-regenerate when transplanted into immune-deficient mice. However, the exact role of CD44 in cancer stem cells remains unclear in part because CD44 exists in various isoforms due to alternative splicing. Methods: Gain- and loss-of-function methods in different models were used to investigate the effects of CD44 on breast cancer stemness. Cancer stemness was analyzed by detecting SOX2, OCT4 and NANOG expression, ALDH activity, side population (SP) and sphere formation. Glucose consumption, lactate secretion and reactive oxygen species (ROS) levels were detected to assess glycolysis. Western blot, immunohistochemical staining, ELISA and TCGA dataset analysis were performed to determine the association of CD44ICD and PFKFB4 with clinical cases. A PFKFB4 inhibitor, 5MPN, was used in a xenograft model to inhibit breast cancer development. Results: In this report, we found that the shortest CD44 isoform (CD44s) inhibits breast cancer stemness, whereas the cleaved product of CD44 (CD44ICD) promotes breast cancer stemness. Furthermore, CD44ICD interacts with CREB and binds to the promoter region of PFKFB4, thereby regulating PFKFB4 transcription and expression. The resultant PFKFB4 expression facilitates the glycolysis pathway (vis-à-vis oxidative phosphorylation) and promotes stemness of breast cancer. In addition, we found that CD44ICD and PFKFB4 expressions are generally up-regulated in the tumor portion of breast cancer patient samples. Most importantly, we found that 5MPN (a selective inhibitor of PFKFB4) suppresses CD44ICD-induced tumor development. Conclusion: CD44ICD promotes breast cancer stemness via PFKFB4-mediated glycolysis, and therapies that target PFKFB4 (e.g., 5MPN therapy) may lead to improved outcomes for cancer patients.
Therapeutic targeting of PFKFB3 and PFKFB4 in multiple myeloma cells under hypoxic conditions
Biomark Res 2022 May 16;10(1):31.PMID:35578370DOI:10.1186/s40364-022-00376-2.
The treatment of multiple myeloma (MM) patients has been dramatically changed by the introduction of new agents; however, many patients relapse. Hypoxia is a critical component of the bone-marrow microenvironment. 6-Phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFKFB) is responsible for maintaining cellular levels of fructose-2,6-bisphosphate, which regulates glycolysis. We found that the gene expressions of PFKFB3 and PFKFB4 were elevated under hypoxic conditions. Treatments with the PFKFB3 inhibitor, PFK158, and PFKFB4 inhibitor, 5MPN, were found to inhibit the growth of myeloma cells. The combined treatment of myeloma cells with carfilzomib and PFK158 or 5MPN was more cytotoxic than either drug alone. Caspase 3/7 activity and cellular cytotoxicity were also increased. In addition, the combined treatment was effective in the bortezomib-resistant cell line. Our data also suggest that administration of PFKFB3 and PFKFB4 inhibitors may be a powerful strategy against myeloma cells and to enhance the cytotoxic effects of proteasome inhibitors in hypoxic conditions.
Targeting the sugar metabolism of tumors with a first-in-class 6-phosphofructo-2-kinase (PFKFB4) inhibitor
Oncotarget 2015 Jul 20;6(20):18001-11.PMID:26221874DOI:10.18632/oncotarget.4534.
Human tumors exhibit increased glucose uptake and metabolism as a result of high demand for ATP and anabolic substrates and this metabolotype is a negative prognostic indicator for survival. Recent studies have demonstrated that cancer cells from several tissue origins and genetic backgrounds require the expression of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 4 (PFKFB4), a regulatory enzyme that synthesizes an allosteric activator of glycolysis, fructose-2,6-bisphosphate. We report the discovery of a first-in-class PFKFB4 inhibitor, 5-(n-(8-methoxy-4-quinolyl)amino)pentyl nitrate (5MPN), using structure-based virtual computational screening. We find that 5MPN is a selective inhibitor of PFKFB4 that suppresses the glycolysis and proliferation of multiple human cancer cell lines but not non-transformed epithelial cells in vitro. Importantly, 5MPN has high oral bioavailability and per os administration of a non-toxic dose of 5MPN suppresses the glucose metabolism and growth of tumors in mice.
Correlations between microbial indicators, pathogens, and environmental factors in a subtropical estuary
Mar Pollut Bull 2009 Sep;58(9):1374-81.PMID:19464704DOI:10.1016/j.marpolbul.2009.04.015.
The objective of this study was to evaluate whether indicator microbes and physical-chemical parameters were correlated with pathogens within a tidally influenced Estuary. Measurements included the analysis of physical-chemical parameters (pH, salinity, temperature, and turbidity), measurements of bacterial indicators (enterococci, fecal coliform, Escherichia coli, and total coliform), viral indicators (somatic and MS2 coliphage), viral pathogens (enterovirus by culture), and protozoan pathogens (Cryptosporidium and Giardia). All pathogen results were negative with the exception of one sample which tested positive for culturable reovirus (8.5MPN/100L). Notable physical-chemical parameters for this sample included low salinity (<1ppt) and high water temperature (31 degrees C). Indicator bacteria and indicator virus levels for this sample were within average values typically measured within the study site and were low in comparison with levels observed in other freshwater environments. Overall results suggest that high levels of bacterial and viral indicators were associated with low salinity sites.
