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. $LD_{50}$ determination revealed that the investigated extracts of 'Igernella and Ircinia spp' were 4.69 and 134.7 mg/l00 g b.wt., respectively, when injected 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.
