| Hazard Information | Back Directory | [Description]
Tunicamycin mixture is a mixture of tunicamycins with variable trans-2,3-unsaturated branched chain fatty acid (BFCA) chain lengths. Tunicamycins are anti-microbial agents that are active against Gram-positive bacteria, fungi, and viruses.1 They inhibit the N-acetylhexosamine (HexNAc) phosphotransferase family of enzymes in bacteria and prevent peptidoglycan biosynthesis.2 In eukaryotes, they inhibit N-acetylglucosamine (GlcNAc) phosphotransferase (GPT), preventing the first step in N-linked glycosylation and inducing the unfolded protein response and cell death.2,3,4 The cellular toxicity of tunicamycins is linked to the trans-2,3-unsaturated BCFA, and saturated BCFA-containing tunicamycin derivatives, such as TunR1 (Item No. 31537) and TunR2 (Item No. 31538), have reduced toxicity.2,5 Tunicamycins impair glycosylation of the receptor tyrosine kinases EGFR, HER2, HER3, and IGF-1R, which prevents their translocation out of the endoplasmic reticulum and Golgi apparatus and reduces their protein levels and activity.6 Tunicamycin sensitizes EGFR inhibitor-resistant U251 glioma and Bx/PC-3 pancreatic adenocarcinoma cells to irradiation.6 | [Chemical Properties]

The tunicamycins are a family of lipophilic nucleosides with fatty acids conjugated to an aminoglycoside group. The complex comprises analogues, tunicamycins I to X. This composition is typical of other products less precisely described as tunicamycins A to D. The tunicamycins act by blocking the formation of N-glycoside linkages to proteins via inhibition of formation of dolichol monophosphate from N-acetylglucosamine-1-phosphate. Tunicamycin blocks the synthesis of all N-linked glycoproteins (N-glycans) and causes cell cycle arrest in G1 phase. Tunicamycins are broadly active against prokaryotes, eukaryotes and viruses. | [Definition]
ChEBI: A mixture of antiviral nucleoside antibiotics produced by Streptomyces lysosuperificus. It contains at least 10 homologues comprising uracil, N-acetylglucosamine, an 11-carbon aminodialdose called tunicamine, and a fatty aci
linked to the amino group of the tunicamine. The homologues vary in the composition of the fatty acid moiety. | [General Description]
Tunicamycin was first isolated from Streptomyces lysosuperificus based on its antiviral activity. It contains N-acetylglucosamine and inhibits glycoprotein biosynthesis, including virus membrane glycoproteins. | [Biochem/physiol Actions]
Cell permeable: yes | [storage]
+4°C | [Purification Methods]
The components of this nucleotide antibiotic from Streptomyces sp. are purified by recrystallising 3 times from hot glass-distilled MeOH, and the white crystals are dissolved in 25% aqueous MeOH and separated on a Partisil ODS-10_ column (9.4 x 25 cm) [Magnum-9 Whatman] using a 260nm detector. The column is eluted with MeOH/H2O mixture adjusted to 1:4 (v/v) then to 2:4 (v/v). The individual components are recovered and lyophilised. Ten components have been isolated, and all were active (to varying extents) depending on the lengths of the aliphatic side-chains. The mixture has UV max at 205 and 260nm (A 1cm 230 and 110). It is stable in H2O at neutral pH but unstable in acidic solution. It inhibits protein glycosylation.
