Phosphorylation of Unnatural Phosphatidylinositols with Phosphatidylinositol 3-Kinase
摘要:
Phosphatidylinositol analogs (PIC2PIC18) having a series of saturated fatty acid (C2-C18) at sn-2 position were synthesized and subjected to the phosphorylation reaction with phosphatidylinositol 3-kinase (PI 3-kinase). The reactivity of PIC8 with PI 3-kinase turned out to be comparable to that of natural PI, although PIC18 was not phosphorylated under the same condition. The chirality of sn-2 center was not responsible for the phosphorylation reaction. (C) 2000 Elsevier Science Ltd. All rights reserved.

A method for the stereocontrolled synthesis of a bacterial phosphoglycolipid (PGL1) isolated fromthermophilicbacteria is described. The key features of the synthesis include a highly α‐selective glycosylation reaction between a trichloroacetimidate donor and a D‐lyxose‐derived primary alcohol acceptor and the late‐stage incorporation of the phospholipid.
