Abstract: Embodiments of the invention relate to natural and synthetic inositolphospholipid (IPL) materials, their preparation and applications. They provide compositions of the parent IPL comprising phosphatidylinositol (PI), PI-phosphates (phosphoinositides) and derivatives and analogues, and a process for their production starting from natural IPL. The embodiments further provide functional derivatives of PI for biomedical applications including a platform for drug design and delivery to therapeutic targets in the phosphoinositide mediated cellular signaling and allied cascades. The embodiments pertain to IPL having absolute stereo-structure. The embodiments further pertain to unique IPL and PI product compositions for defined applications, particularly pharmaceutical compositions for prophylaxis and treatment of diseases related to aberrant cellular and nuclear signaling mediated by PI and PI derived phosphates, and associated phosphoinositide specific enzymes including PI-PLC and PI 3-kinase.

Abstract: Disclosed is a new structural class of amphiphilic molecules which incorporate a hydrophilic material or polymer attached, at spatially distinct sites, to at least two hydrophobic residues. Certain of the amphiphilic molecules comprise a plurality of hydrophobic moieties. All such amphiphilic molecules have a common structural motif and, in contact with water, display surface activity and self-assemble into multimolecular aggregates and liquid crystalline phases. Also disclosed are enhanced stability liposomes that incorporate such amphiphilic molecules via unique interactions, and methods of using such formulations in a variety of applications including drug delivery, nutrition, bio-diagnostics, cosmetics, blood products and related applications.

Abstract: The present invention provides novel compounds comprising cellular phosphoinositides and analogues tagged with stable or radioactive isotopes. The present invention also provides novel methods for the preparation of the said phosphoinositides by syntheses, and novel key intermediates of synthesis; the novel methods of synthesis are applied also for the preparation of the phosphoinositides in non-labelled form. In addition, the present invention discloses a class of novel compounds as isotope labelled key precursors of labelled phosphoinositides. These precursors are derivatives of the target phosphoinositides, labelled with stable or radioactive isotopes, wherein OH and phosphate groups are blocked with temporary protecting groups.

Abstract: This invention relates to inositolphospholipids, particularly to synthetic phosphatidyl-myo-inositols (PtdIns), ceramide-phosphoinositols (CerPhosIns) and their structural and stereochemical analogues. The invention specifically provides a novel approach to synthesis of inositolphospholipids which is suitable for laboratory scale preparation as well as for large scale industrial production. The synthetic approach is applicable equally well for the preparation of inositolphospholipids carrying saturated lipid chains, unsaturated lipid chains with one or more double or triple bonds, chains with hydroxyl, amino and other functional groups, or combinations of these. In addition, it provides novel high purity diastereomer molecular species of inositolphospholipids that have unequivocally defined structure and absolute stereochemistry in both the myo-inositol and the glycerol residues and are obtainable only by the present new approach.
