Saikogenin D 

Saikogenin D is isolated from?Bupleurum chinense, has anti-inflammatory effects. Saikogenin D activates epoxygenases that converts arachidonic acid to epoxyeicosanoids and dihydroxyeicosatrienoic acids, and the metabolites secondarily inhibit prostaglandin E2 (PGE2) production. Saikogenin D results in an elevation of [Ca²⁺]i due to Ca²⁺ release from intracellular stores^[1][2].

Saikogenin D (1-20 μM) inhibits PGE2 production induced by the Ca²⁺ ionophore A23187 in a concentration-dependent manner with an IC₅₀ value of 3 μM in C6 rat glioma cells^[1].
Saikogenin D (10-100 μM) elevates [Ca²⁺]i in a concentration-dependent manner with a EC₅₀ value of 35 μM in the presence or absence of extracellular Ca2+ in C6 rat glioma cells^[1].
