1. Fraxinellone significantly reduced weight loss and diarrhea in mice and alleviated the macroscopic and microscopic signs of the disease. 2. Fraxinellone exhibited a variety of insecticidal activities including feeding-deterrent activity, inhibition of growth, and larvicidal activity. 3. Fraxinellone has effect in the midgut metabolism of Mythimna separata (M. separata), via protease (especially the weak alkaline trypsin-like enzyme), carboxylesterase and glutathione S-transferase.
Preskimmianine is the biogenetic precursor of skimmianine.It can significantly inhibit nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated BV2 cells.
Dasycarpol(9beta-Hydroxyfraxinellone) shows significant neuroprotective activity against glutamate-induced neurotoxicity in primary cultures of rat cortical cells at a concentration of 0.1 microM. Dasycarpol also shows moderate inhibitory activity on lung
