prepared and evaluated as novel hypoxic cell selective cytotoxic agents. In vitro, N-(2-aminoethyl)-N-methyl-3-nitro-4-(1-methyl-1-nitroethyl)benzene sulfonamide hydrochloride (11) proved to be preferentially toxic to hypoxic EMT6 mammary carcinoma cells. At 1 mM concentration in vitro, 11 reduced the surviving fraction of these hypoxic cells to 3 x 10(-3) with no effect on aerobic cells. In radiation
制备了含有硝基异丙基和(脲基氧基)甲基的碱性硝基苯磺酰胺,并将其评估为新型的低氧细胞选择性细胞毒剂。在体外,N-(2-氨基乙基)-N-甲基-3-硝基-4-(1-甲基-1-硝基乙基)苯磺酰胺盐酸盐(11)被证明对低氧EMT6乳腺癌细胞有优先毒性。在体外浓度为1 mM时,11将这些低氧细胞的存活分数降低至3 x 10(-3),而对需氧细胞没有影响。在放射实验中,有11种似乎充当缺氧细胞放射增敏剂以及选择性细胞毒剂。但是,以200 mg / kg ip或100 mg / kg iv的剂量对植入了实体EMT6肿瘤的BALB / c小鼠给药11时,没有明显的体内细胞毒性或放射增敏活性的证据。
