Abstract

The first series of synthetic 1-aza-9-oxafluorenes with cytostatic activities in the micromolar range was evaluated as cyclin-dependent kinase (CDK1) inhibitors. Activity was found to be selective in comparison to the inhibition of other kinases within the CDK family. Compounds were shown to inhibit the membrane-efflux pump P-glycoprotein responsible for multidrug resistance in cancer cells. First structure-activity relationships are discussed.
