Tropodithietic acid
Cytotoxic disulfide antibiotic / Displays potent broad-spectrum anticancer activity.1 Displays cytotoxic effects on mammalian cell lines (neuronal N2a cells and OLN-93 cells as model systems for nerve cells and glia) acting via disruption of mitochondrial membrane potential, activation of ERK1/2 and induction of HSP32/HO-1 (considered as a sensor of oxidative stress).2 A broad-spectrum antibiotic agent produced by marine bacteria which does not appear to induce resistance after long-term exposure.3
