Long chain aliphatic diamine, 1,7-diaminoheptane (DAHP), was selected as template for creation of novel nano-scaled 3D-guest-host- supramolecular coordination polymer (SCP); 3[(Cu3(CN)3)2.(DAHP)], 1. Crystal structure of SCP 1 consists of new bi-fold [Cu3(CN)3]2 fragments containing tetrahedral copper(I) atoms which are arranged in unique way to create 3D-structure exhibiting wide cavities enable to encapsulate the long chain DAHP as guest molecule. The topology of 1 had been elucidated by spectroscopic methods, elemental analysis, transmission electron microscopy (TEM) and scanning electron microscope (SEM). The nanosized SCP1 exhibits excellent catalytic activity towards mineralization of methyl violet (MV), methylene blue (MB) and indigo carmine (IC) dyes using H2O2 as oxidant within very short times. Scavenger techniques and disodium terephthalate (NaTA) as selective photoluminescence prob of hydroxyl radical had been utilized to elucidate mineralization mechanism. Nano-SCP 1 exhibits sigmoidal dose-response inhibition of cells viability giving low IC50 values for the tested cell as well as was examined for rate erythrocyte hemolysis and antioxidant activity utilizing ABTS assay. Also, SCP1 exhibits good antimicrobial activity due to the low MIC values keeping it a promising drug candidate for the treatment of the tested bacterial and fungal infections.

主客体纳米氰化铜和 1,7-二氨基庚烷的介导自组装:设计、催化和生物学评价

长链脂肪族二胺,1,7-二氨基庚烷(DAHP)被选为模板,用于创建新型纳米级3D-客体-宿主-超分子配位聚合物(SCP);3 [(Cu 3 (CN) 3 ) 2 .(DAHP)], 1 . SCP 1 的晶体结构由包含四面体铜 (I) 原子的新双折叠 [Cu 3 (CN) 3 ] 2碎片组成,这些碎片以独特的方式排列以创建具有宽腔的 3D 结构,能够将长链 DAHP 封装为客分子。1的拓扑已通过光谱方法、元素分析、透射电子显微镜(TEM)和扫描电子显微镜(SEM)阐明。纳米尺寸的 SCP 1对使用 H 2 O 2作为氧化剂在很短的时间内对甲基紫 (MV)、亚甲蓝 (MB) 和靛胭脂 (IC) 染料的矿化表现出优异的催化活性。清除剂技术和对苯二甲酸二钠 (NaTA) 作为羟基自由基的选择性光致发光探针已被用于阐明矿化机制。Nano-SCP 1表现出细胞活力的 sigmoidal 剂量反应抑制,为测试细胞提供低 IC50 值,并使用 ABTS 测定检查红细胞溶血率和抗氧化活性。还有,SCP由于 MIC 值低,1表现出良好的抗菌活性,使其成为治疗测试细菌和真菌感染的有希望的候选药物。
