Tunicamycin is a homologous nucleoside antibiotic mixture that inhibits N-linked glycosylation and blocks GlcNAc phosphotransferase (GPT), causing ER stress by accumulating unfolded proteins in the endoplasmic reticulum. It induces G1 phase cell cycle arrest, inhibits gram-positive bacteria, yeasts, fungi, and viruses, and has anticancer activity. Additionally, tunicamycin increases exosome release in cervical cancer cells.

Synonyms: Tunicamycin Mixture
