  发现具有抗癌活性的卤代苯并噻二嗪衍生物**

  摘要：

  线粒体呼吸复合物 II (CII)，也称为琥珀酸脱氢酶，在线粒体代谢中起关键作用。已知但效力低的 CII 抑制剂对癌细胞具有选择性细胞毒性，包括基于苯并噻二嗪的抗低血糖二氮嗪。在此，我们首次研究了苯并噻二嗪衍生物对CII抑制的构效关系及其对癌细胞的影响。与二氮嗪相比，CII 抑制增加了 15 倍，尽管其 IC 50值为微摩尔。新衍生物的细胞毒性评估导致鉴定出比二氮嗪具有更大抗肿瘤作用的化合物，其中最有效的化合物具有 IC 50在三阴性乳腺癌细胞模型中为 2.93±0.07 μM，对非恶性细胞具有高选择性，是临床药物 5-氟尿嘧啶的两倍多。没有发现细胞毒性和 CII 抑制之间的相关性，因此表明该支架的作用机制尚未明确。本文描述的衍生物代表了用于三阴性乳腺癌治疗发现的有价值的热门化合物。

  8-chloro-substituted 3-alkylamino/cycloalkylamino-4H-1,2,4-benzothiadiazine 1,1-dioxides is described. Their inhibitory effect on the insulin releasing process and their vasorelaxant activity was compared to that of previously reported 7-chloro-3-alkylamino/cycloalkylamino-4H-1,2,4-benzothiadiazine 1,1-dioxides. “5-Chloro” compounds were found to be essentially inactive on both the insulin-secreting and

  Diversely substituted 3-isopropylamino-4H-1,2,4-benzothiadiazine 1,1-dioxides are known to be potent K-ATP channel openers, with several drugs being selective for the SUR1/Kir6.2 channel subtype. This work examined the biological activity, tissue selectivity, and in vitro metabolic stability of hydroxylated analogues of 3-isopropylaminobenzothiadiazine dioxides. Because of the presence of a chiral center, the R and S isomers were prepared separately and characterized. R isomers were systematically found to be more potent and more selective than S isomers on pancreatic tissue (compared to vascular smooth muscle tissue), leading to compounds with an improved sulfonylurea receptor 1 (SUR1) selectivity. An in vitro metabolic study revealed that 7-chloro-3-isopropylamino-4H-1,2,4-benzothiadiazine 1,1-dioxide (1a) was rapidly biotransformed and led in part to a mixture of the corresponding (R)- and (S)-3-(1-hydroxy-2-propyl)amino-substituted derivatives. Radioisotopic experiments characterized one of the most potent and SUR1-selective enantiomers, (R)-7-chloro-3-(1-hydroxy-2-propyl)amino-4H-1,2,4-benzothiadiazine 1,1-dioxide 13a, as being a K-ATP channel opener. Moreover, 13a exhibited an enhanced metabolic stability. Such a compound can be considered as a new lead candidate displaying improved physicochemical (hydrosolubility) and pharmacological (tissue selectivity) properties as well as improved metabolic stability compared to its nonhydroxylated counterpart, 1a.
