KHELLIN Chemical Properties,Usage,Production

Uses

vasodilator (coronary), photosensitizer

Uses

Khellin has been used as a reference standard for supercritical fluid extraction of khellin from Ammi visnaga L. fruits to understand the various medicinal effects of γ-Pyrones by reversed phase HPLC method.

Definition

ChEBI: Khellin is a furanochrome in which the basic tricyclic skeleton is substituted at positions 4 and 9 with methoxy groups and at position 7 with a methyl group. A major constituent of the plant Ammi visnaga it is a herbal folk medicine used for various illnesses, its main effect being as a vasodilator. It has a role as a vasodilator agent, a bronchodilator agent, an anti-asthmatic agent and a cardiovascular drug. It is an organic heterotricyclic compound, an oxacycle and a furanochromone. It is functionally related to a 5H-furo[3,2-g]chromen-5-one.

brand name

Ammivin (Marion Merrell Dow); Khelloyd (Hoechst-Roussel).

Synthesis Reference(s)

Journal of Medicinal Chemistry, 26, p. 1672, 1983 DOI: 10.1021/jm00366a002

General Description

Khellin, is reported to be an efficient drug for treating vitiligo when combined with ultraviolet A irradiation.

Purification Methods

Crystallise khellin from H2O, MeOH, pet ether or Et2O. The hydrochloride has m 98o(dec) (from EtOH/HCl). [Beilstein 19 II 236, 19 III/IV 2816, 19/6 V 320.]
