novel biologically active molecules, and many have been successfully exploited across and within different target families. Examples include indole, quinolone, isoquinoline, benzofuran and chromone, etc. In the current study, we focus on synthesising a novel hybrid scaffold constituting naturally occurring benzophenone (14) and indanone (22) ring systems, leading to a general structure of 2-(diphenylmethylene)-2
在过去的几十年中,特殊结构的设计已成为发现和优化新型生物活性分子的有用方法,并且许多结构已在不同目标家族之间和内部成功利用。例子包括吲哚、喹诺酮、异喹啉、苯并呋喃和色酮等。在当前的研究中,我们专注于合成一种由天然存在的二苯甲酮( 14)和茚满酮(22)环系统组成的新型杂化支架,从而得到2-的一般结构(二苯基亚甲基)-2,3-二氢-1H-茚-1-酮( 23 )。据推测,由于存在与微管蛋白结合小分子茚满辛 (10)和雌激素受体 (ER) 拮抗剂他莫昔芬 ( 24 ) 相关的共同特征,这种新的混合系统将提供增强的抗癌活性。成功合成并表征了关键杂合分子,并对癌细胞系:MCF7(乳腺癌)和 SKBR3(乳腺癌)、DU145(前列腺)和 A549(肺癌)进行了体外细胞毒性测定。甲基、氯和甲氧基、对位取代的二苯甲酮杂化物表现出最大程度的细胞毒性,并且E构型衍生物45、47和49明显最有效。我们进一步验证
