Abstract

Alkyl-lysophospholipids are analogues of 2-lysophosphatidylcholine which have been reported to have selective antitumor activity. A survey of the in vitro activity of racemic 1-octadecyl-2-methoxy-glycero-3 phosphorylcholine on in vitro clonogenicity in soft agar and tritiated thymidine incorporation was conducted on bone marrow specimens from a series of patients with acute myelogenous leukemia (AML) and chronic myelocytic leukemia (CML) and hematologically normal individuals. A dose- and time-dependent inhibition of colony formation and thymidine incorporation was observed in the normal and leukemic specimens. No selective effect of the compound could be demonstrated under the conditions employed in these studies.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.
