Inhibition of the HIV-1 rev–RRE complex formation by unfused aromatic cations
摘要:
RNA viruses cause a wide range of human diseases. Development of new agents to target such viruses is an active area of research. Towards this goal, a series of diphenylfuran cations as potential inhibitors of the Rev-RRE complex have been designed and synthesized. Analysis of the interaction of the diphenylfurans with RRE and TAR RNA model systems by gel shift assays indicates that they exhibit both sequence and structure-dependent binding modes. Our results show a strong interaction between the diphenylfuran ring system and RRE bases, while the TAR interactions are much weaker with the compounds that are the best inhibitors of Rev-RRE.

2,5-Diphenylthiophene-based macrocycles were synthesized by Ni-mediated coupling of the corresponding building units. X-ray analysis revealed that the cyclic trimer had a saddle-shaped structure due to the steric demands of the biphenyl and thiophene-phenylene units, whereas DFT calculation showed that the cyclic dimer had a rigid and almost coplanar structure regardless of the steric hindrance between
2,5-二苯基噻吩基大环化合物是通过相应结构单元的 Ni 介导偶联合成的。X 射线分析表明,由于联苯和噻吩 - 亚苯基单元的空间需求,环状三聚体具有马鞍形结构,而 DFT 计算表明,环状二聚体具有刚性且几乎共面的结构,而与它们之间的空间位阻无关。联苯单元的苯环。此外,环状三聚体的堆积图显示大环和溶剂分子的交替堆叠层。
