| | Avermectin B1b Usage And Synthesis |
| Uses | Avermectin B1b is the minor component (<20%) of a commercially available anthelmintic used to control parasitic nematodes in livestock. Avermectin B1b contains a isopropyl residue in the 25-position. In vitro and in vivo studies have shown this analogue to be active, but less potent than the B1a analogue | | Definition | ChEBI: Avermectin B1b is an avermectin. | | Brand name | (Merck)Avomec [Veterinary] (Merial); Bovitin

(Merck). | | Biological Activity | avermectin b1 is a mixture of avermectins containing >80% avermectin b1a and <20% avermectin b1b. b1a and b1b have very similar biological and toxicological properties. | | in vitro | the avermectins are insecticidal and antihelmintic compounds derived from various laboratory broths fermented by the soil bacterium. avermectin b1 is a natural fermentation product of this bacterium. | | in vivo | avermectin b1 therapy resulted in significant decreases in mean strongyle egg after treatment. all horses given ivermectin or avermectin b1 had zero strongyle egg counts 14 and 28 d after treatment. the oral administration of avermectin b1 appeared to be highly efficacious against intestinal strongyles and onchocera microfilaria [1]. | | references | [1] mogg td, pollitt cc, willmore jp, thompson h. efficacy of avermectin b1 given orally against equine intestinal strongyles and onchocera microfilaria. aust vet j. 1990;67(11):399-401. |
