Baimaside
Based on 3 publication(s) in Google Scholar
Baimaside (Quercetin 3-O-sophoroside) is a flavonoid cholinergic function modulator that binds to SARS-CoV-2-related targets. Baimaside regulates the expression of cholinergic system-related proteins and acetylcholine levels, improves scopolamine-induced learning and memory impairment, protects hippocampal neurons, inhibits pollen protein fluorescence, and protects pollen DNA. Its biosynthesis is regulated by multiple enzymes. Baimaside is completely absorbed in rats, undergoes phase Ⅱ metabolism and gut microbiota decomposition, and inhibits the invasion and proliferation of SARS-CoV-2 and its variants, making it suitable for research related to Alzheimer's disease and COVID-19.
