鉴定结合并干扰microrna功能的小分子是治疗microrna相关病理的一种有吸引力的方法。然而,只有少数已知的小分子可以直接与microrna相互作用。在这里,我们报告了使用小分子微阵列(SMM)筛选方法来鉴定直接与pre-miR-21发夹结合的低分子量化合物。使用该方法鉴定的化合物对RNA具有良好的亲和力(范围在0.8-2.0 μM),并且不由多阳离子支架组成。一些亲和力最高的化合物抑制Dicer介导的加工,而在线探测实验表明,这些化合物结合在靠近Dicer位点的发夹顶端环上。这项工作提供了证据,证明可以开发小分子直接结合并抑制miR-21。
The identification of small molecules that bind to and perturb the function of microRNAs is an attractive approach for the treatment for microRNA-associated pathologies. However, there are only a few small molecules known to interact directly with microRNAs. Here, we report the use of a small molecule microarray (SMM) screening approach to identify low molecular weight compounds that directly bind to a pre-miR-21 hairpin. Compounds identified using this approach exhibit good affinity for the RNA (ranging from 0.8–2.0 μM) and are not composed of a polycationic scaffold. Several of the highest affinity compounds inhibit Dicer-mediated processing, while in-line probing experiments indicate that the compounds bind to the apical loop of the hairpin, proximal to the Dicer site. This work provides evidence that small molecules can be developed to bind directly to and inhibit miR-21.
