A series of novel substituted aminobenzophenone derivatives containing nitrogen mustard moiety (5a–f) were synthesized and characterized on the basis of their IR, 1H NMR, 13C NMR, CHN, and mass spectral data. All the compounds when evaluated for chemical 4-(4-nitrobenzyl) pyridine alkylating activity proved to be active alkylating agents. All the synthesized compounds were subjected to physicochemical
合成了一系列含有氮芥子部分(5a - f)的新型取代氨基二苯甲酮衍生物,并根据其IR,1 H NMR,13 C NMR,CHN和质谱数据进行了表征。当评估4-(4-硝基苄基)吡啶烷基化化学活性时,所有化合物均证明是活性烷基化剂。通过计算,在线软件和QikProp 3.2对所有合成的化合物进行中枢神经系统(CNS)活动所需的理化参数测定。日志P值和分析的其他计算机模拟ADME理化指标位于良好BBB渗透所需的范围之间。对人癌细胞系的体外抗增殖活性。研究了549(肺),COLO 205(结肠),U 87(胶质母细胞瘤)和IMR-32(神经母细胞瘤)。大多数测试化合物显示出有效的抗肿瘤活性,尤其是化合物(5f)显示出最高的抗CNS癌细胞活性,与苯丁酸氮芥和多西紫杉醇相当。初步的构效关系(SAR)表明,5-氯氨基二苯甲酮-芥末系列(5a-c)比5-硝基氨基二苯甲酮-芥末系列(5d-f)表现出更好的抗肿瘤活性。
