Hypoxia selective cytotoxins having the structural formula ##STR1## wherein D, E, F and G, independently, are carbon or nitrogen, with the proviso that three or more of D, E, F and G are carbon; R.sub.1 and R.sub.2, independently, are selected from the group consisting of methyl, halo, hydro, trifluoromethyl, methoxy, cyano, and methylsulfo; R.sub.3 and R.sub.4, independently, are selected from the group consisting of methyl, ethyl, phenyl, naphthyl, tertiary butyl, halo, halomethylene, hydro, trifluoromethyl, cyano and methylsulfo, or R.sub.3 and R.sub.4 taken together are a substituted or unsubstituted five or six-membered nonaromatic ring system; n is an integer 1 through 5; X is carbon or nitrogen; and Z is a physiologically acceptable anion, are disclosed. The compounds are useful as radiosensitizers or chemosensitizers, especially in the treatment of cancer patients.
公开了具有结构式## STR1##的缺氧选择性细胞毒素,其中D、E、F和G分别独立地为碳或氮,但须满足D、E、F和G中至少有三个为碳;R.sub.1和R.sub.2分别选自甲基、卤代、氢、三氟甲基、甲氧基、氰和甲基磺酰等组成的群体;R.sub.3和R.sub.4分别选自甲基、乙基、苯基、萘基、叔丁基、卤代、卤代亚甲基、氢、三氟甲基、氰和甲基磺酰等组成的群体,或R.sub.3和R.sub.4一起构成取代或未取代的五元或六元非芳香环系;n为1到5的整数;X为碳或氮;Z为生理上可接受的阴离子。这些化合物在肿瘤患者的放射增敏剂或化学增敏剂治疗中特别有用。
