substituents exhibited potent inhibition of catalytic activity of hTopoIIα while not showing DNA intercalation. Molecular docking studies and molecular dynamics (MD) simulation analysis, ATPase-kinetics and ATP-dependent plasmid relaxation assay revealed the catalytic mode of inhibition of the title compounds plausibly by blocking the ATP-binding site. N-Fused aminoimidazoles showed potent anticancer activities

With the development of a novel microwave-assisted one-pot tandem de-tert-butylation of tert-butyl amine in an Ugi-type multicomponent reaction product, tert-butyl isocyanide as a useful convertible isonitrile has been explored for the first time affording access to molecular diversity of pharmaceutically-important polycyclic N-fused imidazo-heterocycles.
