Mycale Laxissima

Two new steroid oligoglycosides, mycalosides J (1) and K (2) have been isolated from the polar extract of the Caribbean sponge Mycale laxissima. Their structures have been elucidated as (20 R)-3- O-{[α-D-Gal p-(1→2)-β-D-Ara p-(1→3)]-[β-D-Gal p-(1→4)]-β-D-Glc p}-15-oxo-3β,21-dihydroxy-cholest-5-ene (1) and (22 E,20 R,24 R)-3- O-{[α-D-Gal p-(1→2)-β-D-Ara p-(1→3)]-[β-D-Gal p-(1→4)]-β-D-6- O-acetyl-Glc p}-3β,4β,15α,21-tetrahydroxy-24-methylcholesta-5,22-diene (2) by interpretation of spectral data. Mycaloside J (1) was structurally identified as a 4-nor derivative of the previously known mycaloside G. Mycaloside K (2) was shown to be an epimer at C-24 of the previously known mycaloside D.
