TunR2

TunR2 is an antibiotic and derivative of tunicamycin (Cay-11445). It is active against B. subtilis (MIC = 0.3 µg/ml) and increases the efficacy of the beta-lactam antibiotics oxacillin (Cay-23954), methicillin (Cay-21007), and penicillin G (Cay-21615) against B. subtilis when used at a concentration of 0.4 µg/ml. Unlike tunicamycin, TunR2 is non-toxic to S. cerevisiae (MIC = >10 µg/ml) and does not inhibit glycosylation in a protein N-glycosylation assay. TunR2 also has reduced antiproliferative activity against MDA-MB-231 and CHO cells compared with tunicamycin.Formal Name: N-((2S,3R,4R,5R,6R)-2-(((2R,3R,4R,5S,6R)-3-acetamido-4,5-dihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)-6-((R)-2-((2R,3S,4R,5R)-5-(2,4-dioxotetrahydropyrimidin-1(2H)-yl)-3,4-dihydroxytetrahydrofuran-2-yl)-2-hydroxyethyl)-4,5-dihydroxytetrahydro-2H-pyran-3-yl)-12-methyltridecanamide.
