Twenty nitrogen mustard analogues derived from 5-(aziridin-1-yl)-2,4-dinitrobenzamide (CB 1954, 1) were evaluated as candidate prodrugs for gene-directed enzyme prodrug therapy (GDEPT) in Chinese hamster V79 cell lines engineered to express Escherichia coli nitroreductase (NR). Structural variations within the series included the use of N-dihydroxypropyl and (N-dimethylamino)ethyl carboxamide side
在中国仓鼠V79细胞株中,将20种衍生自5-(叠氮基-1-基)-2,4-二硝基苯甲酰胺的氮芥类类似物(CB 1954,1)评估为基因定向酶前药治疗(GDEPT)的候选前药。表达大肠杆菌硝基还原酶(NR)。该系列中的结构变化包括使用N-二羟丙基和(N-二甲基氨基)乙基羧酰胺侧链,使用芥末上的氯,溴,甲磺酰基和碘代离去基团,以及区域异构变化。用表达NR的细胞和不表达NR的细胞系作为对照,测定化合物的细胞毒性(IC50)。混合物中非表达细胞经历其50%的细胞毒性(称为TE50)所需的NR表达细胞的比例用于评估化合物诱导旁观者效应的能力。
