Cytoprotective organoselenium compounds for oligodendrocytes

Arabian Journal of Chemistry, 2021
Abstract Herein we report the synthesis of peptide-like and tetrazole-based organoselenium compounds via Ugi and Ugi-azide reactions, respectively. The organoselenium compounds' intrinsic cytoprotective and antioxidant capacities were evaluated in 158 N and 158JP murine oligodendrocytes.
