Utility of 3-O-methyl-N-acetyl-D-Glucosamine, an N-acetylglucosamine kinase inhibitor, for accurate assay of glucokinase in pancreatic islets and liver

Enzyme Protein 1994;48(3):135-42.PMID:8589800DOI:10.1159/000474980.

Glucokinase, an enzyme that catalyzes the phosphorylation of glucose, constitutes the key regulatory step in glucose metabolism in pancreatic islets and liver. We found that 3-O-methyl-N-acetyl-D-Glucosamine (3-O-methyl-GlcNAc) potently inhibits glucose phosphorylation by N-acetylglucosamine kinase whereas glucokinase is not at all affected by this hexosamine. The addition of 3-O-methyl-GlcNAc to the assay system for glucokinase in rat liver extracts, which contain a high activity of glucokinase (glucose as substrate) relative to N-acetylglucosamine kinase (N-acetyl-D-glucosamine as substrate), affected neither Km nor Vmax values of glucokinase. On the other hand, both Km and Vmax values of glucokinase in rat pancreatic islet extracts, in which N-acetylglucosamine kinase activity is higher than glucokinase activity, were significantly lowered by the use of 3-O-methyl-GlcNAc as an inhibitor of N-acetylglucosamine kinase.

Inhibition of N-acetylglucosamine kinase and N-acetylmannosamine kinase by 3-O-methyl-N-acetyl-D-Glucosamine in vitro

Eur J Biochem 1992 Mar 15;204(3):1165-8.PMID:1312935DOI:10.1111/j.1432-1033.1992.tb16743.x.

During the search for inhibitors of N-acetylneuraminic acid biosynthesis, it was shown that 3-O-methyl-N-acetylglucosamine competitively inhibits the N-acetylglucosamine kinase of rat liver in vitro with a Ki value of 17 microM. N-Acetylmannosamine kinase is inhibited non-competitively with a Ki value of 80 microM. In a human hepatoma cell line (HepG2), 3-O-methyl-N-acetyl-D-Glucosamine (1 mM) inhibits the incorporation of 14C-N-acetylglucosamine and 14C-N-acetylmannosamine into cellular glycoproteins by 88% and 70%, respectively.

Insecticidal activities of constituents of Litsea cubeba fruit extracts effective against the maize weevil (Coleoptera: Curculionidae)

J Insect Sci 2017 Sep 1;17(5):103.PMID:29117378DOI:10.1093/jisesa/iex079.

In this study, we investigated the insecticidal activities, including contact toxicity, fumigant toxicity, and repellent activity, of Litsea cubeba fruit extracts against Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae). The extracts, obtained by liquid-liquid extraction in n-hexane, ethyl acetate, chloroform, and water were analyzed by gas chromatography-mass spectrometry. Among the different extract types, chloroform extracts exhibited the strongest repellent, contact, and fumigant activities against S. zeamais. The main components of the chloroform extracts were identified as laurine (21.15%) and 2,6-diisopropyl aniline (16.14%), followed by chlorobutanol (10.54%), 3-O-methyl-N-acetyl-D-Glucosamine (10.03%), and 6-methyl-5-hepten-2-one (8.33%). Among the identified components of the chloroform extracts, chlorobutanol showed the strongest fumigant toxicity (LD50 = 21.91 mg/liter), contact toxicity (LD50 = 54.25 µg/adult), and repellent activity against S. zeamais. These results indicate that L. cubeba fruit extracts possess natural insecticide-like activities against S. zeamais.
