A method for preparing triazinyl-substituted carboranyl systems using 1,2-, 1,7-, and 1,12-C2B10H12 as cores and [di(alkyl)amino]triazine as substituents is described. A sulfur-containing o-carboranyl cage compound was also incorporated into the 1,3,5-triazine network to generate new types of hybrid compounds having a thio-ether linkage. Within the series of synthesized compounds, one showed increased water solubility arising from the effective camouflaging of the central p-carboranyl unit by the polar functional groups at the periphery. Furthermore, the same compound exhibited high boron uptake in B-16 melanoma cells with low toxicity, showing promise as a BNCT agent.
本文介绍了一种以 1,2-、1,7- 和 1,12-C2B10H12 为核心,以[二(烷基)
氨基]三嗪为取代基制备三嗪基取代
硼烷体系的方法。此外,还在 1,3,5 三嗪网络中加入了一种含
硫邻
硼烷笼化合物,以生成具有
硫醚连接的新型杂化化合物。在合成的一系列化合物中,有一种化合物的
水溶性得到了提高,这是由于外围的极性官能团有效地掩盖了中心对
硼烷基单元。此外,同一化合物在 B-16
黑色素瘤细胞中表现出较高的
硼吸收率和较低的毒性,显示出作为 BNCT 药剂的前景。
