  Stille Coupling Reactions in the Synthesis of Hypoxia-Selective 3-Alkyl-1,2,4-Benzotriazine 1,4-Dioxide Anticancer Agents

  摘要：

  The introduction of a 3-alkyl substituent is a key step in the synthesis of 1,2,4-benzotriazine 1,4-dioxide hypoxia-selective anticancer agents, such as SN29751. The Stille reaction of 3-chloro-1,2,4-benzotriazine 1-oxides ( BTOs) 5 was inhibited by the presence of electron donating substituents on the benzo ring, thus limiting the range of compounds available for SAR studies. The use of 3-iodo-BTOs 8 did not provide a significant improvement in the yields of 3-ethyl-BTOs 6. Microwave-assisted Stille coupling of chlorides 5 gave dramatically improved yields, which were consistently superior to those from the corresponding iodides 8. The application of microwave-assisted synthesis extended the range of substituted BTOs available for SAR studies and provided an efficient, scalable synthesis of the investigational anticancer agent, SN29751 ( 1).

  肿瘤中的缺氧导致对化学疗法和放射疗法治疗的抵抗，但提供了一种环境，其中缺氧激活的前药（HAP）在生物还原后被激活以释放靶向细胞毒素。苯并三嗪 1,4-二-N-氧化物 (BTO) HAP、替拉扎明 (TPZ, 1) 已与放射疗法联合进行了广泛的临床评估，以帮助杀死缺氧的肿瘤细胞。尽管化合物 1 没有获得临床使用批准，但它促进了其他 BTO 的开发，例如 3-烷基类似物 SN30000, 2。普遍认为 BTO 中的细胞毒素来自化合物的电子还原形式。识别细胞毒性自由基，以及它们是否在选择性杀死缺氧肿瘤细胞中起作用，对于 BTO 类抗癌前药的持续开发很重要。在这项研究中，硝酮自旋陷阱与电子自旋共振相结合，为化合物 1、2 和 3-苯基类似物、化合物 3 和 4 形成芳基自由基提供了证据，这些化合物形成以碳 C 为中心的自由基。此外，高浓度的 DEPMPO (5-(二乙氧基磷酰基)-5-甲基-1-吡咯啉

  Compounds bactericidal against both replicating and nonreplicating Mtb may shorten the length of TB treatment regimens by eliminating infections more rapidly. Screening of a panel of antimicrobial and anticancer drug classes that are bioreduced into cytotoxic species revealed that 1,2,4-benzotriazine di-N-oxides (BTOs) are potently bactericidal against replicating and nonreplicating Mtb. Medicinal chemistry optimization, guided by semiempirical molecular orbital calculations, identified a new lead compound (20q) from this series with an MIC of 0.31 mu g/mL against H37Rv and a cytotoxicity (CC50) against Vero cells of 25 mu g/mL. 20q also had equivalent potency against a panel of single-drug resistant strains of Mtb and remarkably selective activity for Mtb over a panel of other pathogenic bacterial strains. 20q was also negative in a L5178Y MOLY assay, indicating low potential for genetic toxicity. These data along with measurements of the physiochemical properties and pharmacokinetic profile demonstrate that BTOs have the potential to be developed into a new class of antitubercular drugs.
