Synthesis and Biological Activity of the D-3-Deoxy-3-fluoro and D-3-Chloro-3-deoxy Analogs of Phosphatidylinositol
摘要:
The naturally occurring inositol derivative, L-quebrachitol (1), serves as starting material for the synthesis of D-3-deoxy-3-fluoro- and D-3-chloro-3-deoxy-myo-inositol (4, 28). Their transformation into the title compounds 22 and 40 (abbreviated as FPI and CPI, respectively) is accomplished by benzylation of all hydroxyl groups but OH-1 to which the phosphatidic acid side chain is subsequently attached using the phosphoramidite protocol, and hydrogenolytic deprotection. Compounds 4 and 28, as reported earlier, exhibit moderate and high selectivity, respectively, in the growth inhibition of v-sis transformed vs wild type murine NIH 3T3 cells if myo-inositol is absent but are inactive in the presence of physiological inositol levels. On the other hand, FPI possesses a nearly 2 orders of magnitude higher activity but no selectivity both in the absence or presence of myo-inositol. CPI is inactive as is the simplified analogue 24 of FPI in which the phosphatidic acid moiety has been replaced by an octadecyl group.

To explore the biological significance of the D-3 position phosphorylation of the second messenger D-myo-inositol 1,4,5-trisphosphate (IP3) in cellular signalling, three novel D-3-substituted analogues of IP3 have been synthesized; their binding and Ca2+-release profiles at the IP3-receptor have been studied and shown to correlate with the steric requirement of the D-3 substituent.

evaluated as substrates for phosphatidylinositol synthase and uptake by intact cells. 1D-3-Amino-, -3-chloro-, and -3-(acetylthio)-3-deoxy-myo-inositols were all synthesized by nucleophilicdisplacement of the 6-O-(trifluoromethyl)sulfonyl group of 1L-1,2:3,4-di-O-cyclohexylidene-5-O-methyl-6-O-[(trifluoromethyl)-sulfon yl] - chiro-inositol (which was prepared from L-quebrachitol), respectively, by reaction
