CHEBI:142133 ·resolve ·ANTIBACTERIAL ·EXACT SEEDED

A member of the class of octahydronaphthalenes that is (2R,4aS,5R,6R,8aS)-2,5-dimethyl-6-[(1E)-prop-1-en-1-yl]-1,2,3,4,4a,5,6,8a-octahydronaphthalene in which the hydrogen at position 5 has been replaced by a (Z)-hydroxy[(5S)-5-(hydroxymethyl)-2,4-dioxopyrrolidin-3-ylidene]methyl group. Produced by the dual culture of Trichoderma harzianum and Catharanthus roseus callus, it exhibits significant antimicrobial activity against Gram-positive bacteria such as Staphylococcus aureus and Bacillus subtilis. — ChEBI
