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
识别与microRNA结合并扰乱其功能的小分子是治疗microRNA相关疾病的一种有吸引力的方法。但是,只有很少的小分子可以直接与microRNA相互作用。在这里,我们报告使用小分子微阵列(SMM)筛选方法来鉴定直接结合pre-miR-21发夹的低分子量化合物。使用此方法鉴定的化合物对RNA表现出良好的亲和力(范围为0.8-2.0μM),并且不由聚阳离子支架组成。几种具有最高亲和力的化合物会抑制Dicer介导的加工,而在线探针实验表明,该化合物与Dicer部位近端的发夹顶端环结合。
