Exploring the therapeutic potential of steroidal alkaloids in managing Alzheimer’s disease

Steroidal alkaloids are secondary metabolites that are often found in plants, fungi and sponges. These compounds are considered as a source of bioactive compounds for the treatment of chronic diseases, such as neurological disorder like Alzheimer’s disease (AD). Some examples of alkaloid derivatives currently used to treat AD symptoms include galantamine, huperzine A, and other alkaloids. AD is a multifactorial disease caused by multiple factors such as inflammation, oxidative stress, and protein aggregation. Based on the various important neuroprotective activities and different pharmacological effects of steroidal alkaloids with polypharmacological modulatory effects, they can lead to the development of new drugs for the treatment of AD. There are limited studies on the involvement of steroidal alkaloids in AD. Therefore, the mechanisms and neuroprotective abilities of these compounds are still poorly understood. The purpose of this review article is to provide an overview of the mechanism, toxicity and neuroprotective benefits of steroidal alkaloids and to discuss future possibilities to improve the application of steroidal alkaloids as anti-AD agents. The therapeutic value and limitations of the steroidal alkaloid are investigated to provide new perspectives for future clinical development studies.
