2-Arylquinzolinones with various substitutions on the aromatic rings were obtained by thermal cyclodehydration/dehydrogenation on reacting anthranilamides and benzaldehydes. The compounds had superior topo I-inhibitory activities but were generally inactive against topo IIα. Among the 6-methyl-, 6-amino-, and 7-methylquinazolinones, 6-amino-substituted derivatives displayed potent cytotoxicity at submicromolar
The present invention discloses a method for the enzyme-mediated, site-specific, in-vivo precipitation of a water soluble molecule in an animal. The enzyme is either unique to tumor cells, or is produced within a specific site (e.g., tumor) at concentrations that are higher than that in normal tissues. Alternatively, the enzyme is conjugated to a targeting moiety such as an antibody or a receptor-binding molecule.
