koumine Chemical Properties,Usage,Production

Description

The Chinese drug 'Kou-wen', said to be derived from Gelsemium elegans Benth., is stated to contain this alkaloid which forms rhombic prisms from Me2 CO. It has [α]23D - 265° (EtOH) and forms a crystalline hydrochloride, m.p. 255°C (dec.) and a hydrobromide, m.p. 269°C (dec.).

Chemical Properties

Soluble in acetone, chloroform, ether, benzene and other organic solvents, insoluble in water. Sourced from Gelsemium elegans (Gardn. et Champ.) Benth.

Occurrence

Koumine is an alkaloid isolated from Gelsemium elegans Benth.

Uses

Koumine is known to attenuate the lipopolysaccharide-stimulated inflammation in RAW264.7 macrophages.

in vivo

Koumine is less toxic, with the median lethal dose (LD50) of 300.0 mg/kg on Wistar rats. Koumine (0.6, 3, or 15 mg/kg/per, p.o.) exhibits antirheumatic properties in rats with adjuvant-induced arthritis (AIA) and collagen-induced arthritis (CIA)[2].
Koumine inhibits the increase in cytokines in joint tissue and TNF-α level in serum at 15 mg/kg, and suppresses the increase in the serum level of IL-1β at 3 and 15 mg/kg[2].
Koumine (0.28, 7 mg/kg, s.c.) significantly reduces neuropathic pain after nerve injury. Koumine suppresses the increased Iba-1 protein level[3].
