Description | Monactin is a mactrotetralide antibiotic and a non-selective ionophore for monovalent cations, including potassium, sodium, and lithium. Monactin is isolated from Streptomyces and has antiproliferative activity[1][2][3]. |

In Vitro | Monactin displays strong antiproliferative activity against A2780 ovarian cancer cells (IC50 0.13 μM), A2058 melanoma cells (0.02 μM), and H522-T1 non small-cell cancer lung cells (0.01 μM)[3]. Monactin inhibits TCF/β-catenin transcriptional activity[4]. At a concentration of 10 μM, nigericin and monactin inhibited growth of Streptococcus faecalis, and the inhibition was reversed by addition of excess K(+)[5]. |
In Vivo | Monactin is potent uncoupler of oxidative phosphorylation and inducer of ATP hydrolysis in rat liver mitochondria[1]. |
