Cat. No.: HY-N1440 Purity: 99.97%
Handling Instructions

Koumine is an alkaloid separated from Gelsemium elegans, shows potent anti-tumor activity. Koumine up-regulates the Bax/Bcl-2 ratio and caspase-3 expression in human breast cancer cells. Koumine has anxiolytic, antistress, antipsoriatic, and analgesic activities, protects against the development of arthritis in Rheumatoid arthritis (RA) animal models.

Description

Koumine is an alkaloid separated from Gelsemium elegans, shows potent anti-tumor activity. Koumine up-regulates the Bax/Bcl-2 ratio and caspase-3 expression in human breast cancer cells[1]. Koumine has anxiolytic, antistress, antipsoriatic, and analgesic activities[3], protects against the development of arthritis in Rheumatoid arthritis (RA) animal models[2].

In Vitro

Koumine (0.5, 1 and 2 mg/mL) dose- and time-dependently inhibits the proliferation of MCF-7 cells, with an IC50 of 124 µg/mL at 72 h. Koumine induces apoptosis, causes cell cycle arrest at G2/M phase[1].
Koumine (0.5, 1 and 2 mg/mL) up-regulates the Bax/Bcl-2 ratio and caspase-3 expression in a dose-dependent manner in MCF-7 Cells[1].
Koumine (25, 50, 100, and 200 μM) decreases the protein and mRNA levels of microglia M1 polarization factors in LPS-induced BV2 cells[3].

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].
