title: Cytotoxic activity of 6-alkynyl- and 6-alkenylpurines.
abstract: 6-Alkynyl- and 6-alkenylpurines have been screened for cytotoxic activity against a human chronic myelogenous leukemia cell line; K-562 cells using a [(3)H]-thymidine incorporation assay. Most alkynes displayed cytotoxicity comparable to, or better than, the known anticancer drugs 6-mercaptopurine and fludarabine. The 6-alkenylpurines, which are promising plant growth stimulators and 15-lipoxygenase inhibitors, exhibited only low toxicity.
