  (+/-)-7-(2-carboxypyrrolidin-1-yl)-1-cyclopropyl-6-fluoro-8-nitro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid 在 sodium dithionite 、 potassium carbonate 作用下， 以40%的产率得到(+/-)-4-cyclopropyl-11-fluoro-1,6-dioxo-1,4,5,6,6a,7,8,9-octahydropyrido[2,3-f]pyrrolo[1,2-a]quinoxaline-2-carboxylic acid

  Heterocycles [h]-Fused onto 4-oxoquinoline-3-carboxylic acid, III.1 Facile synthesis and antitumor activity of model heterocycles [a]-fused onto pyrido[2,3-f]quinoxaline-3-carboxylic acids

  摘要：

  Direct interaction between 7-chloro-1-cyclopropyl-6-fluoro-8-nitro-4oxo-1,4-dihydroquinoline-3-carboxylic acid and each of (S)-proline, (2S,4R)-4hydroxyproline and (S)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid in hot aqueous ethanolic NaHCO3 yielded the corresponding optically pure N-(4-oxoquinolin-7-yl)-alpha-amino acids. The latter derivatives underwent reductive lactamization upon treatment with Na2S2O4 in aqueous ethanol to afford moderate yields of the respective pyrido[2,3-f]quinoxaline-3-carboxylic acid [fused]- to tetrahydropyrrolo[1,2-a]-, tetrahydrohydroxylpyrrolo [1,2-a] -and tetrahydroisoquinolino[2,3-a]heterocyclics 10-12, respectively. The antitumor activity against four human tumor cell lines showed that 10-12 displayed high levels of cytotoxicity as compared with Cisplatin. Interestingly, these compounds were more potent against breast carcinoma cell lines (MCF-7 and T-47D) than the lymphoid origin tumor cell lines (Jurkat and BHL-89). In particular, the (S)-proline derivative 10 exhibited preferential cytotoxicity to adherent cells (IC50 = 0.5 mu M), indicative of better potential in blocking the growth of solid tumors rather than the disseminated ones.
