生物活性
Ivermectin B1a 是 Avermectin B1a (HY-15308) 的衍生物，是 Ivermectin (HY-15310) 的主要成分。Ivermectin (MK-933) 是一种广谱抗寄生虫剂。Ivermectin 是应用于抗 SARS-CoV-2/COVID-19 的候选药物。体外研究
Ivermectin belongs to the macrocyclic lactone class of avermectins and consists of a mixture of two homologous compounds, ivermectin B1a (not less than 80%) and ivermectin B1b (not more than 20%). Ivermectin B1a, the major component of Ivermectin, is inactive at a concentration of 0.3 μg/ml, whereas in the case of the minor component, ivermectin B1b, the same concentration produces 100% mortality of snails.
