Avermectin B1a aglycone is an aglycone form of the anthelmintic and insecticide avermectin B1a . It hyperpolarizes P. crassipes muscle fibers with a minimum active concentration (MAC) value of 0.1 μM. Avermectin B1a aglycone decreases survival of C. elegans (MAC = 0.1 μM). In vivo, avermectin B1a aglycone prevents seizures induced by pentylenetetrazole in mice (ED50 = 43.9 mg/kg) without inducing deficits in rotarod performance.
Avermectin B1a monosaccharide is a macrolide anthelmintic and monosaccharide form of avermectin B1a . It is lethal to C. elegans with a minimum active concentration (MAC) value of 0.1 μM. Avermectin B1a monosaccharide also stimulates conductance in isolated shore crab muscle.
2-epi-Abamectin, a degradation product of abamectin, exhibits toxicity towards the two-spotted spider mite in contact assays, possessing an LC50 value of 4 ppm. This indicates it is approximately 100-fold less potent than its precursor, abamectin.
Eprinomectin B1a, composing over 90% of the antiparasitic agent eprinomectin, is a primary component alongside eprinomectin B1b, which constitutes less than 10%. This compound is part of the avermectin family, used as insecticides and anthelmintics.
