Baicalein for Parkinson's Disease

Also known as: 5,6,7-Trihydroxyflavone, Scutellaria baicalensis extract

Baicalein directly inhibits α-synuclein aggregation — the central pathological protein in Parkinson's disease.

Mechanism of Action

Baicalein binds α-synuclein monomers and prevents their assembly into toxic oligomers and fibrils. It inhibits 12/15-lipoxygenase (reducing neuroinflammation), activates Nrf2, and protects dopaminergic neurons through multi-target neuroprotection.

General mechanism: Flavone from Scutellaria. 12/15-LOX inhibitor, α-synuclein aggregation inhibitor, ferroptosis modulator, Nrf2 activator.

Current Evidence

Extensive preclinical evidence for α-synuclein inhibition. Direct binding confirmed by NMR studies. Dopaminergic neuroprotection in MPTP and rotenone models. No PD clinical trials.

Clinical Status: Preclinical. Strong mechanistic rationale for PD.

Safety Profile

Safe. Traditional medicine use. GI effects possible. May interact with iron metabolism at high doses.
