Abstract

A series of 2-nitroaryl-1,2,3,4-tetrahydroisoquinolines 10 and nitro-substituted 5,6-dihydrobenzimidazo[2,1-a]isoquinoline N-oxides 11 have been synthesised and evaluated as potential bioreducible substrates for the enzymes NAD(P)H: quinone oxidoreductase 1 (NQO1) and Escherichia coli nitroreductase (NR). Also prepared and evaluated were 2-(3,5-dinitropyridin-2-yl)-1,2,3,4-tetrahydroisoquinoline 12 and 5,6-dihydro-10-nitropyrido[3″,2″:4′,5′]imidazo[2′,1′-a]isoquinoline 12-oxide 13. Both compounds 10b and 13 were reduced faster by human NQO1 than by CB-1954 [5-(aziridin-1-yl)-2,4-dinitrobenzamide].
