Antimicrobial activity of untenospongin b, a metabolite from the marine sponge hippospongia communis collected from the atlantic coast of Morocco

Abstract

(-)-Untenospongin B isolated from the marine sponge Hippospongia communis has been tested for its antimicrobial activity against bacteria and human pathogenic fungi using agar disk method and was found to possess a broad and strong activity toward the test organisms. Its antifungal activity was further characterized by determination of the minimum inhibitory concentration (MIC) against five fungal species using broth microdilution method.
