Background

Nonactin, monactin, and dinactin mixture is a macrotetralide antibiotic.[1] This product is a mixture of the macrotetralide antibiotic homologs nonactin, monactin, and dinactin that all act as ionophores for monovalent cations.[2],[3],[4],[5],[6],[7] Nonactin is a mitochondrial membrane uncoupler and an inhibitor of adenine nucleotide translocase (ANT; IC50s = 4.4, 3.3, 4.7, and 3.3 μM for recombinant human ANT1-4, respectively).[8],[9] It selectively induces apoptosis in cancer cells and induces tumor regression in mouse xenograft models expressing mutant β-catenin over cancer cells and xenografts expressing wild-type β-catenin.8 Monactin induces swelling of rat liver mitochondria in medium containing either potassium or sodium, stimulates respiration, and uncouples oxidative phosphorylation.[10] It also inhibits Wnt signaling via inhibition of TCF-β-catenin transcriptional activity.[11] Dinactin inhibits T cell proliferation and cytokine production in vitro and reduces pulmonary eosinophilia in antigen-challenged mice.[12] Reference:
