HLY78, a Lycorine (HY-N0288) derivative, is a potent activator of the Wnt/β-catenin signaling pathway. HLY78 targets the DIX domain of Axin and promotes the Axin-LRP6 (lipoprotein receptor-related protein 6) association, thus promoting LRP6 phosphorylation and Wnt signal transduction. HLY78 can be used for subarachnoid hemorrhage (SAH) research.
