TunR1 is an antibiotic and derivative of tunicamycin .1It is active againstB. subtilis(MIC = 0.3 μg/ml) and increases the efficacy of the β-lactam antibiotics oxacillin , methicillin , and penicillin G againstB. subtiliswhen used at a concentration of 0.4 μg/ml. TunR1 (5 μg/ml) is cytotoxic to MDA-MB-231 breast cancer cells and non-cancerous CHO cells. Unlike tunicamycin, TunR1 does not inhibit glycosylation in a protein N-glycosylation assay.
