title: Synthesis of mono- and bifunctional alpha-methylene lactone systems as potential tumor inhibitors.
abstract: Synthetic nono- and bifunctional alpha-methylene lactone derivatives including deoxyvernolepin and kihydrodeoxyvernolepin were tested as inhibitors of the growth of CCRF-CEM human lymphoblastic leukemia cells in culture. The range of ID-50 values for compounds 1-7 (ca. 10(-5)-10(-6)M) was roughly comparable to the doses observed earlier in the CCRF-CEM cell system with synthetic alpha-methylene-gamma-butyrolactones. Of significance is that dihydrodeoxyvernolepin and deoxyvernolepin were at least an order of magnitude more active than natural vernolepin.
