Abstract
Abstract The bioassay-guided purification of chloroform extracts of Kalimeris indica (Linn) Schultz-Bip led to the isolation of three diacylglycerols: 1-O-(9Z,12Z,15Z-octadecatrienoyl)-2-O-hexadecanoylglycerol (1), 1-O-(9Z,12Z,15Z-octadecatrienoyl)-2-O-hexadecanoyl-3-O-α-(6-sulfoquinovopyranosyl)glycerol (2), 1-O-(9Z,12Z,15Z-octadecatrienoyl)-2-O-hexadecanoyl-3-O-[α- d -galactopyranosyl(1 → 6)-O-β- d -galactopyranosyl]glycerol (3). Their structures were established on the basis of spectral and chemical methods. The glyceroglycolipids 2 and 3 exhibited significant PAF receptor binding inhibitory activities. Our studies have identified diacylglycolipids as a novel class of potent PAF antagonist.
