SYNTHESIS OF PHOSPHOLIPID CONJUGATES OF N1-(2-FURANIDYL)-N3-(2-HYDROXYETHYL)-5-FLUOROURACIL
摘要:
The synthesis of phospholipid conjugates of N-1-(2-furanidyl)-N-3-(2-hydroxyethyl)-5-fluorouracil is reported. The strategy for the synthesis is using hexaethylphosphorous triamide, activated by a catalytic amount of iodine, as the phosphorylating reagent in a one-pot reaction resulting in a number of new types of phospholipid-drug conjugates.

The synthesis and biological characterization of some 3-carboxylate isosteres of PAF-acether structurallymodified in positions 1 (ether, carbamate), 2 (acetoyl, ethoxy), and 3 (chain length and polar head group) are reported. All derivatives present antagonist activities against PAF-acether-induced effects in vitro (platelet aggregation) and in vivo (bronchoconstriction and thrombocytopenia in guinea

A process to prepare a vinylidene chloride heteropolymer comprising copolymerizing vinylidene chloride with at least one comonomer selected from the group consisting of alkyl acrylates, non-vinylidene chloride vinyl monomers and combinations thereof in the presence of an indicator, wherein the indicator is soluble in vinylidene chloride, the at least one comonomer, or a mixture of the vinylidene chloride and the at least one comonomer is provided.
The synthesis of some selected PAF-acether homologues with an alkoxy-chain length from C1 to C20 in position 1 is described. All agonist activities are closely correlated among themselves and with the calculated fatty-chain hydrophobicity. After a discussion on recent published results and comparison with our data, we conclude that the ether oxide function is absolutely essential at the glycerol 1-position for potent agonist activity and that potency correlates well with hydrophobicity parameters. We indicate the importance of steric and configurational constraints.
