title: [Antimicrobial activity of polyhydroxynaphthoquinones from sea urchins].
abstract: Antimicrobial activity of polyhydroxynaphthoquinones from sea urchins was studied. 6-Ethyl-2,3,5,7,8-pentahydroxy-1,4-naphthoquinone (equinochrome A) containing the beta-ethyl functional group was found to be the most active substance. Methylation of beta-hydroxyls markedly increased the inhibitory effect of the derivatives as compared to that of the initial quinones.
