4-Adamantyl-5-aryl-3-phenyl-Delta(2)-1, 2,4-oxadiazolines were synthes
ized and evaluated in vitro as antitumor agents against 60 human tumor
cell lines. Some derivatives exhibit both cell selectivity and tumor
growth inhibition activity. In particular, 2,6-dichlorophenyl derivati
ve (2q), the most active of the series, possesses significant activity
on 26 cell lines at 10(-5) M.
