    摘要: The methods and compositions disclosed herein concern the synthesis of a novel class of “two-headed” phospholipid-phosphoinositide hybrids possessing a carbon backbone, such as 2,3-diacylthreitol, erythritol or a synthetic module. The second phospholipid head group allows introduction of a biochemical or chemical moiety in a position orthogonal in space to those occupied by the phosphoinositide head group and the two acyl chains. The diacyl moieties allow for the incorporation of Pea-PIP2 into a lipid bilayer, while the Ptdlns(4,5)P2 moiety in the aqueous layer is specifically recognized by lipid binding proteins. In alternative embodiments of the invention, reporters, for example biotin, fluorophores and/or spin labels, are attached to the free amino group of the head groups of such molecules to specifically target the reporters to the lipid-water interface.

    摘要: Fluorogenic lysophosphatidic acid derivatives which can be used as substrates in a continuous, fluorogenic assay that can be performed in microtiter plates. The assays permit measuring LysoPLD activity levels in normal events such as pregnancy or disease states such as cancer. In addition, the present invention can be adopted to high throughout screening (HTS) for identification of potential inhibitors of lysoPLD activity.
