Abstract:

Two new dammarane triterpenes 3beta-acetyl-20S,24R-dammarane-25-ene-24-hydroperoxy-20-ol (1), 20S,24R-dammarane-25-ene-24-hydroperoxy-3beta,20-diol (2), as well as three known dammarane triterpenes, 3beta-acetyl-20S,25-epoxydammarane-24alpha-ol (3), 20S,25-epoxydammarane-3beta,24alpha-diol (4), 20S-dammarane-23-ene-3beta,20,25-triol (5) were isolated from the fruits of Ligustrum lucidum. Compounds 3-5 were isolated from the fruits of L. lucidum for the first time. Their structures were elucidated by spectroscopic methods.

Antiasthma Drugs: Leukotriene Modifiers

Antiasthma Drugs: Leukotriene Modifiers

Leukotriene modifiers, or cysteinyl leukotriene receptor antagonists, are medications used to manage chronic asthma. These agents target specific inflammatory mediators produced during arachidonic acid metabolism, an essential process in generating inflammation in the body.
Leukotriene modifiers work through two distinct mechanisms:
