Description and Uses

(1R,9S)-(–)-β-Hydrastine is an enantiomer of the alkaloid hydrastine that inhibits dopamine biosynthesis (IC₅₀ = 20.7 μM in PC12 cells) by inhibiting tyrosine hydroxylase activity. It inhibits dopamine release with an IC₅₀ value of 66.5 μM in the presence of high extracellular K⁺ levels. It also inhibits L-type and caffeine-activated store-operated Ca²⁺ channels and prevents Ca²⁺ leakage from intracellular stores.

(-)-β-Hydrastine is an inhibitor of Dopamine biosynthesis.
