phosphorylase

Glycogen phosphorylase-IN-1 is a selective and potent inhibitor of human hepatic glycogen phosphorylase (hlGPa) with inhibitory effects on hlGPa activity and on hepatocyte glycogen-derived glucose production, and can be used in the study of type 2 diabetes mellitus and canine lupus.

Maltoheptaose (aka amyloheptaose) is a activater of phosphorylase B specifically to prepare (neurosin)heptulose-2-phosphate.

D-galactosyl-β1-3-N-acetyl-D-hexosamine phosphorylase (BiGalHexNAcP), a member of the CAZy glycoside hydrolase family GH112, plays a pivotal role in biochemical research by catalyzing the phosphorolysis of lacto-n-biose and galacto-n-biose, yielding Gal-1-P and the corresponding N-acetyl-D-hexosamine [1].

Purine Nucleoside Phosphorylase, an essential enzyme in purine metabolism, plays a critical role in the purine salvage pathway. Its deficiency impairs T cell function. With inorganic orthophosphate as a co-substrate, this enzyme catalyzes the cleavage of the glycosidic bond linking ribose and deoxyribonucleoside, resulting in the production of a purine base and ribose (deoxyribose)-1-phosphate [1].

Maltose phosphorylase (MP) is a dimeric enzyme that participates in starch and sucrose metabolism and catalyzes the conversion of maltose and inorganic phosphate into β-D-glucose-1-phosphate and glucose without requiring any cofactors, such as pyridoxal phosphate.

Sucrose phosphorylase, a bacterial transglucosidase, catalyzes the conversion of sucrose and phosphate into α-D-glucose-1-phosphate and D-fructose. This enzyme can also hydrolyze glucosylated sucrose into α-D-glucose or transfer the glucosyl group to a receptor's hydroxyl group, resulting in new α-D-glucoside products. Its enzymatic activity towards the base, substrate, and product is weak [1].

Phosphorylase Kinase β-Subunit Fragment (420-436) is a peptide fragment (430-436) derived from the β-Subunit of phosphorylase kinase. Phosphorylase kinase, a serine threonine-specific protein kinase, plays a crucial role in activating glycogen phosphorylase for the release of glucose-1-phosphate from glycogen [1].

UDP-sugar pyrophosphorylase (BlUSP) is an enzyme that activates glucose-1-phosphate (Glc-1-P) to UDP-glucose (UDP-Glc) and catalyzes the reversible transfer of the uridyl group from UTP to sugar-1-phosphate, yielding UDP-sugar and pyrophosphate (PPi) [1].

Uric Acid (Lithic acid) is an oxidation product of oxypurines such as XANTHINE and HYPOXANTHINE. It is the final oxidation product of purine catabolism in humans and primates, whereas in most other mammals URATE OXIDASE further oxidizes it to ALLANTOIN.

Disodium monofluorophosphate (NSC248) is a competitive inhibitor of pyruvate kinase and alkaline phosphatase, which also irreversibly inhibits phosphorylase phosphatase.

(-)-p-Bromotetramisole Oxalate (6-Bromolevamisole oxalate) is a potent and non-specific inhibitor of alkaline phosphatase.

BAY R3401 is an orally active inhibitor of glycogen phosphorylase, leading to irreversible and non-selective inhibition of liver glycogenolysis. It suppresses glycogen breakdown in hepatocytes with IC50 values of 27.06 μM in HL-7702 cells and 52.83 μM in HepG2 cells. BAY R3401 is applicable for research in type 2 diabetes.

AVE5688, an inhibitor of glycogen phosphorylase (GP), has IC50 values of 430 nM and 915 nM, and Kd values of 170 nM and 530 nM for rmGPb and rmGPa, respectively. It is suitable for research on type 2 diabetes.

DIPQUO hydrochloride is an activator of the bone marker alkaline phosphatase (ALP), with an EC50 of 6.27 μM in C2C12 cells. DIPQUO hydrochloride promotes mouse and human osteoblast differentiation via activation of p38 MAPK-β.

L-Ascorbic acid 2-phosphate magnesium (2-Phospho-L-ascorbic acid magnesium) functions as an antioxidant and stimulates hepatocyte growth factor (HGF) production. This long-acting vitamin C derivative promotes collagen formation and expression.

Calcium glycerophosphate(CaGP) is an inhibitor of intestinal alkaline phosphatase F3. Calcium glycerophosphate can be a source of calcium and phosphorus in total parenteral nutrition solutions [1] [2].

N6-Methyladenosine 5'-monophosphate disodium salt is a glycogen phosphorylase b activator and an inhibitor of adenylate kinase II.

CP-91149 is a selective glycogen phosphorylase (GP) inhibitor with IC50 of 0.13 μM in the presence of glucose, 5- to 10-fold less potent in the absence of glucose.

Ingliforib (CP 368296) is a novel glycogen phosphorylase inhibitor with antihyperglycemic and cardioprotective properties.

Tracheloside significantly decreases the activity of alkaline phosphatase (IC50: 0.31 μg ml), a level of inhibition comparable to that of tamoxifen (IC50: 0.43 μg ml).

H-HomoArg-OH.HCl (L-Homoarginine hydrochloride) is a specific inhibitor of liver-type alkaline phosphatase.

H-HoArg-OH (a homologue of arginine) is a potent inhibitor of human liver and bone alkaline phosphatase.

Dipsacus saponin X is a triterpenoid saponin derived from Dipsacus asper. It stimulates the proliferation of UMR106 cells and increases alkaline phosphatase（ALP） activity. Additionally, it exhibits anti-acetylcholinesterase（AChE) activity, suggesting potential neuroprotective effects.

Staurosporine (AM-2282) is a protein kinase inhibitor with ATP-competitive and non-selective inhibitory activity (IC50=6 15 2 3 3000 nM) against PKC, PKA, c-Fgr, phosphorylase kinase and TAOK2. Staurosporine also induces apoptosis.
