一系列含有磺酸盐离去基团的3-取代的(5-硝基-2,3-二氢-1 H-苯并[ e ]吲哚-1-基)甲基磺酸盐(nitroCBI)前药经历缺氧选择性代谢,形成有效的DNA小分子沟槽烷基化剂。评估了它们(与氯离去基团类似物进行比较)在有氧和低氧条件下对SKOV3和HT29人肿瘤细胞系培养物的细胞毒性。具有中性侧链的磺酸盐(例如5,6,7-三甲氧基吲哚; TMI)在SKOV3细胞中显示出始终比相应的氯代类似物(2.8-3.1)更高的低氧细胞毒性比(HCR)(34-246),但是这些趋势确实不适用于带有阳离子或极性中性侧链的化合物。

of 19 (5-nitro-2,3-dihydro-1H-benzo[e]indol-1-yl)methyl sulfonate prodrugs containing sulfonateleavinggroups and 7-substituted electron-withdrawing groups is reported. These were designed to undergo hypoxia-selective metabolism to form potent DNA minor groove-alkylating agents. Analogues 17 and 24, containing the benzyl sulfonateleavinggroup and a neutral DNA minor groove-binding side chain, displayed
报道了19(5-硝基-2,3-二氢-1 H-苯并[ e ]吲哚-1-基)甲基磺酸盐前药的合成,该药物含有磺酸盐离去基团和7-取代的吸电子基团。这些被设计用于进行缺氧选择性代谢,以形成有效的DNA小沟烷基化剂。类似物17和24,包含磺酸苄酯离去基团和中性DNA小沟结合侧链,在体外抗增殖试验中显示HT29人癌细胞的缺氧细胞毒性比(HCR)> 1000。四个类似物在一组八种人类癌细胞系中维持较大的HCR。在克隆形成分析中,19HT29细胞的HCR显示为4090。还制备了十种可溶性磷酸盐前药,并以无毒剂量在体内,单独或与放射联合在SiHa人肿瘤异种移植物中进行了评估。化合物34和39的缺氧log 10细胞杀伤(LCK)分别为1.78和2.71,与先前报道的氯化物或溴化物类似物具有同等或更高的活性,因此显示出作为缺氧激活的前药的杰出前景。

Hitting the hypoxic target: Combining a nitro prodrug with a water‐soluble phosphate converts duocarmycinanalogues from highly toxic DNA‐alkylating agents to highly selective antitumor compounds. These prodrugs (see scheme) have outstanding activity against hypoxictumorcells in vivo, cells which are usually considered the most resistant to conventional therapy.
