M. Lopp et al., SYNTHESIS AND ANTIPROLIFERATIVE ACTIVITY OF 15-OXOPROSTAGLANDINS - CONTRIBUTION OF THE OMEGA-CHAIN ENONE GROUP TO CYTOTOXICITY, Bioorganic & medicinal chemistry letters, 4(14), 1994, pp. 1739-1744
15-Oxo metabolites of prostaglandins E2, F2alpha and new 15-oxo prosta
glandin analogues 5 and 7 were found to reveal higher antiproliferativ
e activity than the corresponding 15-hydroxy derivatives on human leuk
emia K562 cells in vitro. The responsibility of the enone group in the
omega-chain of a prostanoid molecule for this activity is suggested.
