We describe several new aromatic nitrogen mustards with various aromatic substituents and boronic esters that can be activated with H2O2 to efficiently cross-link DNA. In vitro studies demonstrated the anticancer potential of these compounds at lower concentrations than those of other clinically used chemotherapeutics, such as melphalan and chlorambucil. In particular, compound 10, bearing an amino
我们描述了几种带有各种芳香族取代基和硼酸酯的新型芳香氮芥子,它们可以被H 2 O 2活化以有效地交联DNA。体外研究表明,与其他临床使用的化疗药物(例如美法仑和苯丁酸氮芥)相比,这些化合物的抗癌潜力较低。特别地,带有氨基酸酯链的化合物10对固有具有高水平活性氧物质的乳腺癌和白血病细胞具有选择性的细胞毒性。重要的是,10是10-14倍美法仑和苯丁酸氮芥对三阴性乳腺癌(TNBC)细胞更有效。同样,10与苯丁酸氮芥或先导化合物相比,对原发性慢性淋巴细胞白血病的毒性更大9。氨基酸侧链的引入提高了10的溶解度和渗透性。此外,10抑制异种移植小鼠中TNBC肿瘤的生长,而没有明显的一般毒性迹象,使该化合物成为临床开发的理想候选药物。
