Metabolite Identification
Common NameMicrocolin H
DescriptionMicrocolin H is a naturally occurring marine lipopeptide that belongs to the chemical class of metabolites. Its chemical structure features a unique arrangement of amino acids that facilitates its interaction with specific biological targets. Microcolin H functions primarily as an autophagy inducer, exhibiting potent antitumor activity by directly binding to phosphatidylinositol transfer proteins α and β (PITPα/β). This binding triggers a cascade of cellular events, including the conversion of LC3I to LC3II and a decrease in p62 levels, which ultimately leads to autophagic cell death in various tumor cell lines (PMID:37963877 ). Furthermore, Microcolin H has demonstrated significant antitumor efficacy in preclinical models, including nude mouse subcutaneous tumor models, while exhibiting low toxicity (PMID:37963877 ). The compound's ability to induce autophagic cell death highlights its potential as a therapeutic agent, particularly through the targeting of PITPα/β, which may serve as a promising avenue for cancer treatment (PMID:37963877 ). Overall, Microcolin H represents a valuable addition to the repertoire of compounds being investigated for their roles in cancer biology and therapeutic development (PMID:40710508 ).
