title: Synthesis and first biological evaluation of 1-aza-9-oxafluorenes as novel lead structures for the development of small-sized cytostatics.
abstract: A first series of novel 1-aza-9-oxafluorenes has been prepared from 3-carbonyl substituted 1,4-dihydropyridines and p-benzoquinone as small-sized cytostatics. Biological evaluation has been carried out in various cancer cell-lines. First structure-activity relationships proved the 4-phenyl substituent to be more favorable than the 4-methyl substituent. Cytostatic properties are discussed.
