D-Fructose-1,6-bisphosphate sodium salt hydrate 是碳水化合物代谢的中间体,包括糖酵解和糖异生。在糖酵解过程中,它是由磷酸果糖激酶磷酸化果糖-6-磷酸产生的。由果糖-1,6-二磷酸酶-1介导的逆反应是糖异生的限速步骤之一。同样的反应也发生在植物的叶绿体中,D-Fructose-1,6-bisphosphate sodium salt hydrate 作为还原性戊糖磷酸循环的一部分。由于癌细胞采用糖酵解作为代谢能量产生的主要来源,这一途径已成为癌症化疗的主要靶点。
HPI-1 (hydrate) is a Hedgehog (Hh) pathway inhibitor that suppresses signaling through Sonic Hh (IC50= 1.5 μM) without significantly affecting Wnt signaling (IC50≥ 30 μM).1HPI-1 suppresses Hh activation induced by loss of Suppressor of Fused or by Gli overexpression, suggesting action at posttranslational modification of Gli protein or at the interaction of Gli with a co-factor.1HPI-1 (hydrate) also inhibits signaling through the oncogenic Smoothened (Smo) mutant SmoM2 in neuron precursors, preventing cell proliferation.1 1.Hyman, J.M., Firestone, A.J., Heine, V.M., et al.Small-molecule inhibitors reveal multiple strategies for Hedgehog pathway blockadeProceedings of the National Academy of Sciences of the United States of America106(33)14132-14137(2009)
α-D-Glucose-1-phosphate is an intermediate in glycogen metabolism.1,2It is a precursor in the biosynthesis of UDP-glucose, the glucose donor in glycogen biosynthesis.2α-D-Glucose-1-phosphate can be formed during glycogen breakdownviaphosphorolytic cleavage of glycogen by glycogen phosphorylase.1It can be converted to glucose-6-phosphate by phosphoglucomutase. α-D-Glucose-1-phosphate is combined with CTP by α-D-glucose-1-phosphate cytidylyltransferase to form CDP-glucose in the first step of CDP-D-tyvelose biosynthesis inS. typhi.3Bacterial sucrose phosphorylase converts sucrose and phosphate into D-fructose and α-D-glucose-1-phosphate.4 1.Berg, J.M., Tymoczko, J.L., and Stryer, L.Glycogen breakdown requires the interplay of several enzymesBiochemistry(2002) 2.Berg, J.M., Tymoczko, J.L., and Stryer, L.Glycogen is synthesized and degraded by different pathwaysBiochemistry(2002) 3.Koropatkin, N.M., and Holden, H.M.Molecular structure of ɑ-D-glucose-1-phosphate cytidylyltransferase from Salmonella typhiJ.

5-Phospho-D-ribose 1-diphosphate (PRPP) is a natural intermediate involved in the pentose phosphate pathway leading to purine, pyrimidine, and histidine metabolism. It is also an intermediate in the synthesis of plant hormones, alkaloids, and other secondary metabolites from glucose. Several phosphoribosyltransferases (PRTases) use PRPP as a substrate to add a 5-phosphoribosyl group to another substrate, as in the production of adenosine monophosphate from adenine and PRPP by adenine PRTase.

β-Glycerophosphate Disodium Salt Hydrate is a classical serine-threonine phosphatase inhibitor used in kinase reaction buffers often used in combination with other phosphatase/protease inhibitors for broad spectrum inhibition and functions as an organic phosphate donor.
(R)-(-)-1,2-Propanediol is the (R)-enantiomer of 1,2-Propanediol, which is derived from glucose through the expression of NADH-linked glycerol dehydrogenase genes in Escherichia coli.
Wnt signaling is required for direct multiple biological processes and also plays key roles in the pathogenesis of various diseases. Cyclic AMP response element-binding protein (CREB) is a transcription factor that is a member of the leucine zipper family of DNA binding proteins. This protein binds as a homodimer to the cAMP-responsive element, an octameric palindrome. The protein is phosphorylated by several protein kinases, and induces transcription of genes in response to hormonal stimulation of the cAMP pathway. Via generating a transcriptionally active complex with β-catenin, CREB acts as a mediator of Wnt signaling.ICG-001 is an inhibitor of β-catenin/CREB mediated transcription. The direct cellular target of ICG-001 is CREB. the inhibitory IC50of ICG-001 against β-catenin/CREB mediated transcription was 3 μM. ICG-001 treatment at the concentration of 25 μM for 24h significantly increased caspase activity in both colon cancer cell lines SW480 and HCT116 cell lines but not in normal colonic epithelial cells CCD-841Co. In a cell growth inhibition assay, the IC50s of ICG-001 against SW480 and HCT116 cells were 4.43 μM and 5.95 μM, respectively.In a SW620 nude mouse xenograft model, an water-soluble analog of ICG-001 given at the dose of 150 mg/kg i.v. once in every 2 days dramatically suppressed tumor growth. In a bleomycin-induced pulmonary fibrosis mice model, ICG-001 given at the dose of 5 mg/kg per day reversed pulmonary fibrosis. In a rat myocardial infarction model, ICG-001 was administrated subcutaneously at the dose of 50 mg/kg/day for 10 days which significantly improved cardiac contractile function after myocardial infarction in the rats.
