therapeutic applications since coding and non‐coding RNAs bear a pivotal role both in viral and bacterial infections as well as in human pathologies such as cancer. Here, we focused on the targeting of HIV‐1 TAR RNA as a promising target for the development of new anti‐HIV therapies but also as an ideal model to validate the discovery of original RNA ligands. First, we performed an initial screening of a
由于编码和非编码RNA在病毒和细菌感染以及人类病理疾病(例如癌症)中都起着关键作用,因此现在已经确立了使用小分子靶向RNA的许多治疗应用前景非常广阔的策略。在这里,我们专注于将HIV-1 TAR RNA作为开发新的抗HIV疗法的有希望的目标,同时也是验证原始RNA配体发现的理想模型。首先,我们对抗TAR的化合物库进行了初步筛选,从而发现了市售的钙通道阻滞剂维拉帕米,作为开发新RNA配体的有前途的化学结构。一系列维拉帕米类似物的合成导致了有希望的结构活性关系,并导致了化合物2h的发现,维拉帕米与吲哚片段之间的结合物,作为一种有效且选择性的TAR结合物,能够抑制Tat / TAR相互作用,IC50为18.8 µM。这项工作为发现原始和选择性的RNA配体提供了库筛选的潜力,并说明了如何仍需要研究针对蛋白质靶标的现有药物进行RNA结合,这是小分子靶向RNA领域中的一种有前途的策略。
