Inhibitory properties of nitrogen-containing adamantane derivatives with monoterpenoid fragments against tyrosyl-DNA phosphodiesterase 1

The compounds containing diazaadamantane and monoterpene moieties have been found to inhibit human purified recombinant tyrosyl-DNA phosphodiesterase 1 (Tdp1), a DNA repair enzyme. Several compounds have been shown to be potent inhibitors of a new structural type. Improved inhibition efficiency has been observed for compounds with longer aliphatic chains and increased flexibility of substituent.
