Novel CDK inhibition profiles of structurally varied 1-aza-9-oxafluorenes
摘要:
A series of 1-aza-9-oxafluorenes with functionally varied 3-substituents have been prepared from N-phenoxycarbonyl-4phenyl-1,4-dihydropyridines and p-benzoquinone and biologically evaluated as inhibitors of various cyclin-dependant kinases. The absence of a 3-hydrogen bond acceptor function leads to a complete loss of inhibitory activity. Differing hydrogen bond acceptor functions surprisingly cause significant shifts in the selectivity of inhibition profiles. (C) 2004 Elsevier Ltd. All rights reserved.
