Abstract:
A new N-acyl taurine (1), together with a new natural product, l-(beta-D-ribofuranosyl)-1,2,4-triazole (4), and two known compounds (2 and 3), were isolated from the sea urchin, Glyptocidaris crenularis. The new N-acyl taurine was elucidated as 2-(5R,15S-dihydroxyeicosanoylamino) ethanesulfonic acid on the basis of spectroscopic (NMR, MS) analyses and the modified Mosher ester method. Compound 2 showed significant toxicity against brine shrimp larvae.
