Tunicamycin

Synonym(s): Tunicamycin A  |  Tunicamycin B2

Class: MraY inhibitor (nucleoside antibiotic)

Spectrum of activity:	Gram-positive
Details of activity:	Interferes with cell-wall synthesis by inhibiting transfer of the peptidoglycan precursor moiety (MurNAc-pentapeptide) to the membrane lipid carrier, undecaprenyl phosphate. Tunicamycin inhibits both MraY and its eukaryotic paralog GlcNAc-1-P-transferase (GPT)
Description:	Natural compound produced by Streptomyces; antitumor activities in various cancers are explored.
Year first mentioned:	1971
Development status:	Experimental
Reason Dropped:	Cytotoxic, causes premature ovarian failure by producing endoplasmic reticulum stress
