Small molecules that promote oligodendrocyte formation have been identified in "drug repurposing" screens to nominate candidate therapeutics for diseases in which myelin is lost, including multiple sclerosis. We recently reported that many such molecules enhance oligodendrocyte formation not by their canonical targets but by inhibiting a narrow range of enzymes in cholesterol biosynthesis. Here we identify enhancers of oligodendrocyte formation obtained by screening a structurally diverse library of 10,000 small molecules. Identification of the cellular targets of these validated hits revealed a majority inhibited the cholesterol biosynthesis enzymes CYP51, TM7SF2, or EBP. In addition, evaluation of analogs led to identification of CW3388, a potent EBP-inhibiting enhancer of oligodendrocyte formation poised for further optimization.

不同的化学支架通过抑制CYP51,TM7SF2或EBP增强少突胶质细胞的形成。

在“药物再利用”筛选中已鉴定出促进少突胶质细胞形成的小分子,以提名用于治疗髓磷脂丢失(包括多发性硬化)的疾病的候选疗法。我们最近报道,许多这样的分子不是通过其正常靶标而是通过抑制胆固醇生物合成中的一小部分酶来增强少突胶质细胞的形成。在这里,我们确定了通过筛选10,000个小分子的结构多样的文库而获得的少突胶质细胞形成的增强子。对这些经过验证的命中的细胞靶标的鉴定显示,大多数抑制了胆固醇的生物合成酶CYP51,TM7SF2或EBP。此外,对类似物的评估导致鉴定出CW3388,CW3388是一种有效的EBP抑制性少突胶质细胞形成增强剂,有望进一步优化。
