RNA采用3D结构,在人类生物学和疾病功能障碍中赋予不同的功能作用。正在积极寻求用小分子治疗靶向RNA结构的方法,这得益于该领域的关键进展,包括开发预测进化上保守的RNA结构的计算工具,以及扩展作用模式并促进与细胞机制相互作用的策略。现有的RNA靶向小分子使用一系列机制,包括指导剪接-通过充当与细胞蛋白质的分子粘合剂(如branaplam和FDA批准的risdiplam),抑制非药物蛋白质的翻译和非编码RNA中功能结构的失活。在这里,我们描述了识别、验证和优化靶向功能性转录组的小分子的策略,并制定了将这些药物推进到未来十年的路线图。用小分子治疗靶向RNA结构的潜力正日益被认识到。在这里,迪士尼和同事审查战略,以确定,验证和优化小分子RNA粘合剂。现有的RNA靶向小分子的例子,以及在该领域的挑战和未来的方向进行了讨论。
RNA adopts 3D structures that confer varied functional roles in human biology and dysfunction in disease. Approaches to therapeutically target RNA structures with small molecules are being actively pursued, aided by key advances in the field including the development of computational tools that predict evolutionarily conserved RNA structures, as well as strategies that expand mode of action and facilitate interactions with cellular machinery. Existing RNA-targeted small molecules use a range of mechanisms including directing splicing — by acting as molecular glues with cellular proteins (such as branaplam and the FDA-approved risdiplam), inhibition of translation of undruggable proteins and deactivation of functional structures in noncoding RNAs. Here, we describe strategies to identify, validate and optimize small molecules that target the functional transcriptome, laying out a roadmap to advance these agents into the next decade. The potential of therapeutically targeting RNA structures with small molecules is being increasingly recognized. Here, Disney and colleagues review strategies to identify, validate and optimize small-molecule RNA binders. Examples of existing RNA-targeted small molecules, as well as challenges and future directions in the field, are discussed.
