  • Title: New acetylenic enol ethers of glycerol from the sponge Petrosia sp.
    Author: Seo Y, Cho KW, Lee HS, Rho JR, Shin J.
    Journal: J Nat Prod; 1999 Jan; 62(1):122-6. PubMed ID: 9917297.
    Abstract:
    Ten acetylenic enol ethers of glycerols, including six new compounds (1-6) and a linear acetylenic alcohol (7), have been isolated from a sponge of the genus Petrosia. The structures of the novel compounds were elucidated by spectroscopic methods. The absolute stereochemistry of 1-7 was determined by chemical transformations and the Mosher method. Some of these compounds exhibited weak cytotoxicity against a human leukemia cell-line (K-562).
