Abstract
The present invention relates to a process for novel sphingolipids and other secondary compounds, based on sphingosine, which comprises the cultivation of an appropriate fungus, the removal of mycelium from the fungus and the isolation of the sphingolipid from the mycelium. Sphingosine-based materials inhibit protein kinase C, provide an anti-inflammatory effect and anti-tumor effect, and these sphingosine-based materials provide protection to plants against pathogenic microorganisms
Description
NOVEDOUS SPHINGOLIPIDS AND THEIR PROCEDURE
The present invention relates to a process for the preparation of sphingolipids. In addition, some of the sphingolipids of this invention possess a polyunsaturated, branched, very unusual sphingosine half that has been previously reported (in the Kenneth L. Rinehart et al., "Ophidiacerebrosides: Cytotoxic Glycosphingolipids Containing a Novel Sphingosine from a Sea Star" (Ofidiacerebrosides: Cytotoxic glycosphingolipids containing a novel Sphingosine from a Starfish), J. Org Chem .1994 (59), pp. 144-147) which is present in the cytotoxic cerebrosides of starfish. Sphingosines and sphingolipids exert many effects on mammary cells [reviewed by S. Spiegel and S. Milstein, J. Membrane Biol. 146, 225 (1995)] and are useful as inhibitors of protein kinase C (US Patent 4,937,232) where said sphingosines and sphingolipids can be of therapeutic value in a number of disease states such as cancer, rheumatic arthritis, complication diabetic, diseases of the central nervous system, etc. In addition, inesitol sphingophospholipids and ceramide inoethylphosphonate represent two types of sphingolipids, which have been described in fungi of the Oomycetos class and which demonstrate biological activity. The sphingophospholipids of Phytophthora capsici have a protective effect on pepper plants against pathogenesis by P. Capsici (European Journal Qf Bíochsmístry) (European Journal of Biochemistry, 1990 (191), pp. 203-209). The ceramide aminoethyl phosphonate of Phytophthora infestans is reported to cause the accumulation of phytoalexins (Physiological and Molecular Plant Pathology) in the plant tissue, an abundance of the plant's tissue and plant pathology, 1986 (28), pp. 215-225). response frequently associated with the activation of disease resistance mechanisms. The present invention relates to a novel sphingolipid that has not been previously described.

R. Schmidt et al., "Sphingosines - an Oxa-Cope Rearrangement Route for Their Synthesis", (Sphingosines - an Oxa-Layer Adaptation Route ", Synthesis, pp. 868-876 (July, 1995) This invention employs fungi , preferably Oomycete fungi, as a convenient source of desired sphingolipids After the isolation of the desired sphingolipid, the sphingolipid can be conveniently modified, if desired, in a sphingolipid child, from which the sphingolipid stem is subjected to hydrolytic conditions to remove the original head group and / or the fatty acid half, to produce a ceramide or a sphingosine phosphorylethanolamine.
