  The invention provides a series of bioactive small molecules that target expanded r(CGG) repeats, termed r(CGG)exp, that causes Fragile X-associated Tremor Ataxia Syndrome (FXTAS). The compound was identified by using information on the chemotypes and RNA motifs that interact. Specifically, 9-hydroxy-5,11-dimethyl-2-(2-(piperidin-1-yl)ethyl)-6H-pyrido[4,3-b]carbazol-2-ium, binds the 5′C G /3′G G C motifs in r(CGG)exp and disrupts a toxic r(CGG)exp-protein complex. Specifically, dimeric compounds incorporating two 9-hydroxyellipticine analog structures can even more potently bind the 5′C G G/3′G G C motifs in r(CGG)exp and disrupts a toxic r(CGG)exp-protein complex. Structure-activity relationships (SAR) studies determined that the alkylated pyridyl and phenolic side chains are important chemotypes that drive molecular recognition of r(CGG) repeats, such as r(CGG)exp. Importantly, the compound is efficacious in FXTAS model cellular systems as evidenced by its ability to improve FXTAS-associated pre-mRNA splicing defects and to reduce the size and number of r(CGG)exp-protein aggregates.

  这项发明提供了一系列针对扩增的r(CGG)重复序列的生物活性小分子，称为r(CGG)exp，导致脆性X相关性震颤共济失调综合征（FXTAS）。该化合物是通过利用相互作用的化学类型和RNA基序的信息来鉴定的。具体来说，9-羟基-5,11-二甲基-2-(2-(哌啶-1-基)乙基)-6H-吡啶并[4,3-b]咔唑-2-离子，结合r(CGG)exp中的5′CG/3′GGC基序，并破坏有毒的r(CGG)exp-蛋白质复合物。具体来说，结合了两个9-羟基椭圆咔啉类似结构的二聚化合物甚至可以更有效地结合r(CGG)exp中的5′CGG/3′GGC基序，并破坏有毒的r(CGG)exp-蛋白质复合物。结构活性关系（SAR）研究确定了烷基化的吡啶基和酚基侧链是驱动对r(CGG)重复序列，如r(CGG)exp的分子识别的重要化学类型。重要的是，该化合物在FXTAS模型细胞系统中表现出疗效，表现为改善FXTAS相关的前mRNA剪接缺陷，并减少r(CGG)exp-蛋白质聚集物的大小和数量。

  Transition metal complexes of amphiphilic corroles, optical isomers and pharmaceutically acceptable salts thereof are useful for neuroprotection and neurorescue, particularly for treatment of diabetes and neurodegenerative diseases. The amphiphilic corrole is preferably a 5,10,15-tris-aryl- or 5,10,15-tris-CF 3 -corrole, and said transition metal complex more preferably has the formula I defined in the specification. Also provided are propargyl-containing corroles carrying one or more radicals substituted by a propargylamino group or one or more nitrogen-containing heteroaryl radicals substituted by propargyl at the ring N atom.
