Toxic effects of alkyl-lysophospholipids on human bone marrow and de novo leukaemias. A short overview.
Alkyl-lysophospholipids (ALPs) are reported to have an antineoplastic activity against leukaemic cells. We have tested some halogen-containing ALPs from the Central Institute of Molecular Biology (H. Brachwitz) in comparison with racemic 1-ostadecyl-2-methyl-glycero-3-phosphocholine (ET-18-OCH3) (P.G. Munder, Max-Planck-Institut für Immunobiologie, Freiburg, FRG). We found freshly dissolved ALPs to be very toxic both to human bone marrow and to leukaemic cells of patients. ALP-incubation before cryopreservation is more toxic to bone marrow (but not to AML blasts) than after cryopreservation. All experiments to test the selectivity and to establish a purging protocol should be done using 1, remission marrow including a cryopreservation step and 2, blasts of de novo leukaemias instead of cell as sensitive as HL 60 to ALP-incubation. We found direct toxicity of ALPs to be not suitable for purging lines of bone marrow from patients in remission.
