| 产品描述 | (+)-Praeruptorin A is a coumarin derivative originally isolated from P. praeruptorum. It prevents LPS-induced increases in IL-1β and TNF-α in a concentration-dependent manner when used at concentrations ranging from 6.25 to 100 µM and IL-6 at concentrations ranging from 25 to 100 µM. It inhibits potassium chloride-induced contraction of isolated rabbit trachea by 50 and 100% when used at concentrations of 4.8 and 30 µM, respectively. Topical administration of (+)-praeruptorin A (0.3 µmol/cm2) reduces edema by 22% in a croton oil mouse model of inflammation. |
