2-cyclopropyl and 5-(2-methylaziridinyl) derivatives, and of these, 5-(aziridin-1-yl)-2-cyclopropyl-3-(hydroxymethyl)-1-methylindole-4 ,7-dione (21) and 3-(hydroxymethyl)-5-(2-methylaziridin-1-yl)-1,2-dimethylindole+ ++-4,7-dione (54) were evaluated in vivo. Both compounds showed antitumor activity both as single agents and in combination with radiation, with some substantial improvements over EO9 (3)

The invention relates generally to pyrrolobenzodiazepine monomer and dimer prodrugs having a glutathione-activated disulfide prodrug moiety, a DT-diaphorase-activated quinone prodrug moiety or a reactive oxygen species-activated aryl boronic acid or aryl boronic ester prodrug moiety. The invention further relates to pyrrolobenzodiazepine prodrug dimer-antibody conjugates.

have any of the values defined in the specification, as well as pharmaceutical compositions comprising such compounds or salts. The compounds are useful for treating cancer in animals.
The present invention is directed to novel heterocyclic substituted pyrazolones, including pharmaceutical compositions, diagnostic kits, assay standards or reagents containing the same, and methods of using the same as therapeutics. The invention is also directed to intermediates and processes for making these novel compounds.
The design, synthesis, and development of INDQ/NO, a novel nitric oxide (NO) prodrug targeted by a bioreductive trigger, are described. INDQ/NO, an indolequinone-diazeniumdiolate is found to be metabolized to produce NO by DT-diaphorase, a bioreductive enzyme that is overexpressed in certain cancers and hypoxic tumors. Cell-based assays revealed that INDQ/NO induces DNA damage and is a potent inhibitor of cancer cell proliferation.
