Propolis May Help Treat Allergies

Inhibitory Activity of Brazilian Green Propolis Components and their Derivatives on the Release of Cys-Leukotrienes
Bioorganic & Medicinal Chemistry, Article in Press

The effects of Brazilian green propolis ethanol extract on Cry j1-induced cys-leukotrienes and histamine release from peripheral leukocytes of patients with allergic rhinitis were investigated.

One of the key mechanisms for the anti-allergic properties of the extract was revealed to be the suppression of cys-LTs release. Furthermore, a series of propolis components and their phenethyl esters were synthesized and evaluated as inhibitors of cys-LTs release.

Artepillin C, baccharin and kaempferide were the major active components of the ethanol extract. The inhibitory activity of artepillin C phenethyl ester was comparable to that of existing LT synthesis inhibitors.
