BIO-Acetoxime is a potent and selective GSK-3a/b inhibitor that reduces invasiveness of gliomas and extends animal survival in intracranial glioma models. Also, BIO-Acetoxime induces Wnt signaling and inhibits CD8+ T cell effector differentiation. BIO-acetoxime is a synthetic derivative of a compound from the Mediterranean mollusk Hexaplex trunculus. BIO-Acetoxime protects cells from varicella infection. BIO-acetoxime may suppress viral gene expression and protect oral epithelial cells from HSV-1 infection.
