Yangambin 

Yangambin, a furofuran lignan, is already isolated from plants such as member of the Annonaceae family, including species of the genus Rollinia: R. pickeli, R. exalbidaand R. mucosa, as well from the Magnolia biondii. Yangambin, a selective PAF receptor antagonist, inhibits Ca²⁺ influx through voltage-gated Ca²⁺ channels, leading to the reduction in [Ca²⁺]i in vascular smooth muscle cells and consequent peripheral vasodilation^[1]. Yangambin exhibits the antiallergic activity against β-hexosaminidase release with an IC₅₀ of 33.8 μM and for anti-inflammatory activity with an IC₅₀ of 37.4 μM^[2].
