What is Chelidonic acid?

The Uses of Chelidonic acid

Chelidonic acid is suitable for use a in homogeneous preparation of native dihydrodipicolinate synthase from pea. It may be used as endocyclic oxygen-containing ligand in the synthesis of aqua[bis(2-pyridylmethyl)amine][chelidonato(1.5-)]-copper(II) chelidonate(0.5-) monohydrate.

Definition

ChEBI: Chelidonic acid is a carbonyl compound and a member of pyrans.

General Description

Chelidonic acid (CA) is a γ-pyrone. It is reported as constituent of the rhizome of Chelidonium majus L. It has many pharmacological effects, such as mild analgesic and antimicrobial effects. Therapeutic potential of CA for the treatment of intestinal inflammation has been investigated. CA is reported as inhibitor of the rat brain glutamate decarboxylase. Biosynthesis of CA in cell suspension cultures of Leucojum aestivum has been studied.

Purification Methods

The acid crystallises from aqueous EtOH. Dry it first at 100o/2hours, then at 160o to constant weight to remove water of crystallisation. It decarboxylates at 220-230o in a vacuum. [Riegel & Zwilgmeyer Org Synth Coll Vol II 126 1943, Beilstein 18 H 490, 18/8 V 646.]
