Saikosaponin I shows strong inhibition activity against influenza virus WSN33.

Resveratrol, a natural polyphenol that possesses anti-oxidant, anti-inflammatory, cardioprotective, blood-sugar-lowering, antiaging, and anti-cancer properties. It has a wide spectrum of targets including cyclooxygenases(i.e. COX, IC50=1.1 μM), lipooxygenases（LOX, IC50=2.7 μM, kinases, sirtuins, c-IAP1, c-IAP2, livin and XIAP. Resveratrol regulates gene transcription via activation of the stimulus-regulated protein kinases Raf and ERK and the stimulus-responsive transcription factors TCF and Egr-1.

Allocryptopine is an aromatic ether, an organic heterotetracyclic compound, a dibenzazecine alkaloid, a cyclic ketone, a tertiary amino compound and a cyclic acetal. Allocryptopine has certain effects on anti-injury for hepatocyte, ameliorating liver function, and prohibiting hepatic fibrosis; it increases mRNA levels of cytochromes P450 1A in human hepatocytes and HepG2 cells independently of AhR. Allocryptopine induces a relaxing effect on the ileum by inhibiting phosphodiesterase enzyme, and thus elevating cellular cAMP and its contractile effect on the urinary bladder by affecting alpha-adrenergic receptors in this tissue, it can block human ether-a-go-go related gene (hERG) potassium channels expressed in HEK293 cells. Allocryptopine is a derivative of berberine extracted from Macleaya cordata. Allocryptopine has anti arrhythmic effects and can effectively block hERG currents.
