制备方法与用途

SMN-C2是RG-7916的紧密类似物，作为选择性RNA结合配体，它能够调节前mRNA剪接。SMN-C2直接结合SMN2前mRNA外显子7上的AGGAAG基序，并促进其构象变化，进而增加未配对核苷酸在内含子6和外显子7连接处的暴露。这种作用有助于将远上游元件结合蛋白1(FUBP1)及其同源物KH型剪接调节蛋白(KHSRP)剪接至SMN-C2/C3-SMN2前mRNA复合物，从而增强SMN2的剪接效率。

  Discovery and Optimization of Small Molecule Splicing Modifiers of Survival Motor Neuron 2 as a Treatment for Spinal Muscular Atrophy

  摘要：

  The underlying cause of spinal muscular atrophy (SMA) is a deficiency of the survival motor neuron (SMN) protein. Starting from hits identified in a high-throughput screening campaign and through structure activity relationship investigations, we have developed small molecules that potently shift the alternative splicing of the SMN2 exon 7, resulting in increased production of the full-length SMN mRNA and protein. Three novel chemical series, represented by compounds 9, 14, and 20, have been optimized to increase the level of SMN protein by >50% in SMA patient-derived fibroblasts at concentrations of <160 nM. Daily administration of these compounds to severe SMA Delta 7 mice results in an increased production of SMN protein in disease-relevant tissues and a significant increase in median survival time in a dose-dependent manner. Our work supports the development of an orally administered small molecule for the treatment of patients with SMA.
