Discovery of 1,2,3-triazole-based fibroblast growth factor receptor modulators

To avoid production of a phospholipidosis-inducing metabolite, we replaced the amide structure of SUN13837 (1) with a 1,2,3-triazole. The resulting 1,2,3-triazole analog of 1 (compound 2) displayed greater neuroprotective activity than 1. Structural modification of 2 yielded compound 10, which showed improved neuroprotective activity and negligible mechanism-based inactivation against CYP3A4. In addition, installation of a methyl group at the 5-position of 1,2,3-triazole of 10 significantly boosted the neuroprotective activity. These 1,2,3-triazole derivatives displayed reduced phospholipidosis risk, sufficient systemic exposure, and high central nervous system penetration, and therefore may be potentially useful agents for the treatment of neurodegenerative diseases.
