Abstract: Berberine is a natural product with a wide range of pharmacological effects. It has
antimicrobial, anti-cancer, anti-inflammatory, anti-hyperlipidemic, neuroprotective, and cholesterollowering
properties, among others. It has been used in traditional Chinese and Ayurvedic medicine
for 3000 years and is generally well-tolerated with few side effects. Its main drawback is low oral
bioavailability, which has hindered widespread clinical use. However, recent interest has surged
with the emergence of evidence that berberine is effective in treating cancer, diabetes, Alzheimer’s
disease, and cardiovascular disease via multiple mechanisms. It enhances insulin sensitivity and secretion
by pancreatic β-cells in Type 2 Diabetes Mellitus in addition to reducing pro-inflammatory
cytokines such as IL-6, IL-1β, TLR4 and TNF-α. These cytokines are elevated in Alzheimer’s disease,
cardiovascular disease, and diabetes. Reductions in pro-inflammatory cytokine levels are associated
with positive outcomes such as improved cognition, reduced cardiovascular events, and
improved glucose metabolism and insulin sensitivity. Berberine is a natural PCSK9 inhibitor, which
contributes to its hypolipidemic effects. It also increases low-density lipoprotein receptor
expression, reduces intestinal cholesterol absorption, and promotes cholesterol excretion from the
liver to the bile. This translates into a notable decrease in LDL cholesterol levels. High LDL
cholesterol levels are associated with increased cardiovascular disease risk. Novel synthetic berberine
derivatives are currently being developed that optimize LDL reduction, bioavailability, and other
pharmacokinetic properties.
