(+/-)-Narwedine(Cas 1668-86-6) Usage

Uses

(+/-)-Narwedine is a natural product that has been studied for its potential therapeutic properties. It increases the amplitude and decreases the frequency of cardiac contractions and would therefore be of value in reducing blood loss during surgery. It also inhibits the action of narcotics and hypnotics, and increases the analgesic effect of morphine as well as the pharmacological effects of caffeine, carbazole, arecoline, and nicotine. There was another postulation that narwedine is the precursor for galanthamine production.

Anti-inflammatory and anti-infectious effects of (+/-)-narwedine, an active constituent from the bulbs of Narcissus tazetta var. chinensis

Liao, J. F., Jan, Y. M., Huang, S. Y., Wang, H. H., & Yu, L. L

, Planta medica, 69(11), 1029-1033.

The researchers evaluated the effects of (+/-)-narwedine on lipopolysaccharide (LPS)-induced nitric oxide (NO) production and tumor necrosis factor-alpha (TNF-alpha) release in macrophages in vitro, as well as its inhibitory effects on the growth of bacteria and fungi. They found that (+/-)-narwedine exhibited significant anti-inflammatory and anti-infectious effects, suggesting that it may have potential as a therapeutic agent for the treatment of inflammatory and infectious diseases.
