Natural phosphatidylserine (PS), which contains two chiral centers, enhances blood coagulation. However, the process by which PS enhanced blood coagulation is not completely understood. An efficient and flexible synthetic route has been developed to synthesize all of the possible stereoisomers of PS. In this study, we examined the role of PS chiral centers in modulating the activity of the tissue factor (TF)-factor VIIa coagulation initiation complex. Full length TF was relipidated with phosphatidylcholine, and the synthesized PS isomers were individually used to estimate the procoagulant activity of the TF-FVIIa complex via a FXa generation assay. The results revealed that the initiation complex activity was stereoselective and had increased sensitivity to the configuration of the PS glycerol backbone due to optimal protein-lipid interactions.

A new stereospecific synthesis of phospholipid derivatives of 1,2- diacyl-sn-glycerols is reported. The synthesis is based on (1) the use of L- glyceric acid as the stereocenter for construction of the optically active phospholipid molecule, (2) preparation of 3-triphenylmethyl-sn-glycerol as the key intermediate for sequential introduction of the primary and secondary acyl functions leading to the chiral diglycerides, and (3) elaboration of the sn-3-phosphodiester headgroup via phosphorylation using 2-chloro-2-oxo-1,3,2- dioxaphospholane, followed by ring opening of the five-membered phosphorus heterocycle with trimethylamine, ammonia, as well as oxygen and sulfur nucleophiles. The sequence has been shown to be suitable for the preparation of both symmetric and mixed-chain diacylglycerols with saturated and unsaturated acyl substituents. Phospholipid headgroups including phosphocholine, phosphoethanolamine, phosphoethanol, and phosphoethylthioacetate functions have been prepared. Application of the method to the synthesis of functionalized phosphatidylcholines has also been demonstrated by incorporating spectroscopically active spin-labeled and fluorescent reporter groups via postsynthetic derivatization of chain terminal ω-aminoalkyl functions of the acyl substituents of the compounds. The synthetic methods developed have a great deal of flexibility, providing convenient routes to a wide range of structurally variable phospholipids for physicochemical, enzymological, and cell-biological studies.

We report an asymmetric synthesis of a potent tyrosine phosphatase inhibitor, RK-682 and its analogs. The absolute stereochemistry of RK-682 was determined to be (R). The inhibitory activities of RK-682 and its analogs, (R)-1a, (S)-1a, (R)-1b and (R)-1c toward various protein phosphatases (VHR, cdc25A, cdc25B, and PPI) are also reported.
