Studies on the anti-inflammatory and analgesic effects of extracts from marine sponges

Two specimens of sponges collected from Red Sea, Egypt, were investigated for their contents of secondary metabolites. The crude extracts of the sponges were tested for their anti-inflammatory and analgesic effects. The toxic effects of the extracts of the two marine sponges were studied. LD50 determination revealed that the investigated extracts of Iregnella and Ircinia sps were 4.69 and 134.7 mg/100g b.wt. respectively, when injected of intraperitoneally in mice. The toxic signs were recorded within the first 24 hrs after injection. Also the two marine sponges extracts showed significant anti-inflammatory and analgesic effects
