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.
