Inducing oligodendrocyte progenitor cell (OPC) differentiation is a novel therapeutic strategy for the treatment of demyelinating diseases such as multiple sclerosis (MS). In the preceding article, we detailed the discovery of compound 1, a potent inducer of OPC differentiation possessing a characteristic spiroindoline structure. Also, we found that N-methylation and des-carbonyl compound 1 (4) led to a loss in potency. Herein, we describe our investigations of a conformation-based hypothesis for OPC differentiation activity based on the preferred conformation of the spiro core, and further structure–activity relationship (SAR) exploration led to the identification of 6-CF3 derivative 8, which was more potent compared to compound 1.
