  Studies have shown that 4-(alkylamino)-5-nitroquinolines possess high selectivity (20-60-fold) for hypoxic tumor cells in vitro, but are not active as hypoxia-selective cytotoxins (HSCs) in vivo. The compounds show inadequate rates of extravascular diffusion, likely due both to sequestration of the bisbasic compounds into lysosomes and rapid nitroreduction. A further series of analogues, designed to counteract these limitations, has been synthesized and evaluated. Analogues bearing one to three electron-donating substituents on the quinoline have one-electron reduction potentials up to 100 mV lower than that of the unsubstituted compound (5), but do not have improved biological activity. The relationship between hypoxic selectivity and rates of metabolic reduction suggests at least two mechanisms of cytotoxicity for this series of 5-nitroquinolines. Compounds with high rates of reduction are toxic via oxygen-sensitive net bioreduction, while compounds which are poor substrates for nitroreduction are toxic through an oxygen-insensitive non-bioreductive mechanism. As rates of metabolic reduction are lowered, the non-bioreductive mechanism of toxicity becomes dominant and hypoxic selectivity is lost. A small series of analogues bearing hydrophilic but neutral side chains were also prepared. Compounds with a dihydroxypropyl side chain retained cytotoxic potency and hypoxic cell selectivity in cell culture assays, and had lowered uptake into lysosomes, but none of three analogues evaluated against KHT tumors in mice showed activity as an HSC in vivo.

  A series of isomeric 4-[[3-(dimethylamino)propyl]amino]nitroquinolines has been synthesized and evaluated as hypoxia-selective cytotoxins and as radioeensitizers of hypoxic cells. The compounds showed widely-differing hypersensitivity factors (ratios of cytotoxicity against wild-type and repair-deficient mammalian cells). Many compounds showed oxygen-sensitive bioreduction resulting in DNA alkylation, while others show oxygen-insensitive modes of action. Of the nitro isomers studied, the 5-nitro showed the greatest hypoxic selectivity. A series of ring-substituted analogues were then prepared, in an effort to lower its reduction potential of -286 mV. Structure-activity studies showed that the effects of substitution on reduction potential were complex, being mediated by electronic and steric effects on the nitro group, as well as by effects on quinoline pK(a). Two compounds of lower reduction potential, the 3- and 8-methyl analogues, showed improved selectivity (47- and 60-fold in a clonogenic assay). These two compounds also showed the highest ''in vitro therapeutic indices'' of the series as hypoxic cell radiosensitizers. Despite these favorable in vitro properties, neither compound had activity against hypoxic cells in SCCVII tumors when administered at 60% of the MTD.

  A divergent and novel protocol for the preparation of both pyrido[2,3,4-kl]acridine and pyrido[4,3,2-kl]acridine alkaloids was developed. This method featured the remote palladium-catalyzed reductive cyclization with Mo(CO)6 as reductant. A wide range of substrates including three types of nitro arenes were tolerated and afforded corresponding products in good to excellent yields. This method has been
