(E)-1-hydroxy-2-(non-1-en-1-yl)quinolin-4-one

CHEBI:137441 ·resolve ·ANTIBACTERIAL ·EXACT SEEDED

A hydroxylamine that is N-hydroxyquinolin-4-one in which the hydrogen at position 2 has been replaced by a (1E)-non-1-en-1-yl group. It is the most active agent produced by Pseudomonas aeruginosa that modulates the growth and virulence of Staphylococcus aureus; the corresponding Z isomer is inactive. — ChEBI
