| Hazard Information | Back Directory | [Description]
The nemadectins are fermentation products of Streptomyces
cyaneogriseus noncyanogenus. Structurally, the
nemadectins lack a disaccharide group at C-13 but differ
from the milbemycins proper because they contain a
trisubstituted double bond at C-26 in their side chains. | [Uses]
Nemadectin is the dominant member of a class of milbemycins bearing unsaturated longer chain groups at the 25-position. Nemadectin shows pronounced nematocidal and insecticidal activity. Nemadectin is the starting material for moxidectin, a commercial anthelmintic. | [in vivo]
Nemadectin is highly effective at 0.6 mg/kg BW against natural infections of all major species of canine intestinal helminths, when administered as a single oral dose, either as a liquid or a tablet[1]. | [IC 50]
