1. Linarin (Acacetin-7-O-rutinoside) (acacetin-7-O-β-d-rutinoside) shows selective dose dependent inhibitory effect on acetylcholinesterase. 2. Linarin alleviates GalN/LPS-induced liver injury by suppressing TNF-α-mediated apoptotic pathways. 3. Linarin prevents A beta-induced neurotoxicity through the activation of PI3K/Akt, which subsequently inhibits GSK-3b and up-regulates Bcl-2. 4. The piperine significantly enhanced the oral absorption of Linarin in rats by inhibiting P-glycoprotein mediated cellular efflux during the intestinal absorption and likely simultaneously by inhibiting the metabolism of Linarin.

Uncarinic acid E has anti-cancer activity, it induces apoptosis in HepG2 cells via accumulation of p53, alters the Bax/Bcl-2 ratio, and activates caspases, resulting in cytochrome c release from the mitochondria. A mixture of uncarinic acid E and 27-O-p-(

1. Corynoxeine is a potent ERK1/2 inhibitor of key PDGF-BB-induced VSMC proliferation and may be useful in the prevention and treatment of vascular diseases and restenosis after angioplasty.

1. Rhynchophylline (Mitrinermine) can protect against ischemic damage, probably via regulating the Akt/mTOR pathway. 2. Rhynchophylline can protect against glutamate-induced neuronal death, can inhibit MA impairment in cultured neurons in vitro. 3. Rhynchophylline and isorhynchophylline have a non-competitive antagonistic effect on the NMDA-type ionotropic glutamate receptors, suggest that these alkaloids exert their protective action against ischemia-induced neuronal damage by preventing NMDA, muscarinic M1, and 5-HT2 receptors-mediated neurotoxicity during ischemia.
