Abstract

BACKGROUND:

Xanthohumol has been reported to have cytoprotection through activation of Nrf2-ARE signaling pathway and; it has capability of scavenging free radicals, suggesting its potential for the prevention of neurodegeneration. However, the bio-incompatibility and blood-brain barrier impermeability of xanthohumol hindered its in vivo efficacy potential for treating Alzheimer's disease (AD).

OBJECTIVE:

We designed and prepared a series of xanthohumol derivatives to enhance the desirable physical, biological and pharmacological properties in particular the blood-brain barrier permeability for intervention of AD.

METHOD:

We designed and synthesized a novel series of 9 xanthohumol derivatives. Their inhibitory effect on amyloid-β (1-42), A β 1-42 , oligomerization and fibrillation as well as neuroprotection against amyloid- β induced toxicities, were explored.

RESULTS:

Among the 9 xanthohumol derivatives, some of them exhibited a moderate to high inhibitory effect on Aβ 1-42 oligomerization and fibrillation. They were biocompatible and neuroprotective to the SH-SY5Y cells by reducing the ROS generation and calcium uploading that were induced by the amyloid- β. Importantly, two of the derivatives were found to be blood-brain barrier permeable showing promising potential for AD treatment.

CONCLUSION:

Two derivatives have been identified to be biocompatible, non-toxic, neuroprotective against A β -induced toxicities and blood-brain barrier permeable highlighting their promising potential as AD drug candidates for future clinical use.
