Rhynchophylline Chemical Properties,Uses,Production

Chemical Properties

Soluble in chloroform, acetone, ethanol, benzene, slightly soluble in ether and ethyl acetate, almost insoluble in petroleum ether. Derived from the hooked branches of Uncaria rhynchopylla (Miq.) Jacks.

Uses

Rhynchophylline is a novel erythropoietin-producing hepatocellular A4 (EphA4) inhibitor.

Definition

ChEBI: A natural product found in Uncaria macrophylla.

in vivo

Rhynchophylline (10 and 30 mg/kg, i.p., once daily for 4 days) protects rats from pMCAO surgery induced ischemic brain damage[2].
Rhynchophylline (100 μM, 2 μL, injected bilaterally in the hippocamp) shows neuroprotective effects against Aβ1-42-induced neurotoxicity in rats[5].
Rhynchophylline (50 mg/kg, p.o., daily, 3-4 weeks) inhibits EphA4 activation in the hippocampus of APP/PS1 mice[6].

Animal Model:Aβ1-42(1.6 μM, 2 μL) treated rats[5]
Dosage:100 μM, 2 μL
Administration:injected bilaterally in the hippocamp
Result:Rescued the soluble Aβ1-42-induced spatial learning and memory deficits.
Inhibited Aβ1-42-induced excessive activation of extrasynaptic NMDARs.
