title: [Interaction of 1-O-alkyl-2-methoxy-sn-glycero-3-phosphocholine and platelet activating factor with blood and tumor cells].
abstract: The effects of the platelet-activating factor (PAF) and the methoxy-PAF analog, 1-O-alkyl-2-methoxy-sn-glycero-3-phosphocholine, on platelet activation, oxidative burst in neutrophils and proliferation of K-562 and P815 cells have been studied. It has been found that the biological activity of methoxy-PAF for human platelets and neutrophils is commensurate with that of PAF. However, the cytotoxic properties of methoxy-PAF are much stronger than the cytotoxicity of PAF for tumour cells. It is concluded that the biological activity of methoxy-PAF is, to a great extent, due to its close structural resemblance to PAF as well as to the inability of cells to perform rapid metabolism of methoxy-PAF.
