Discontinued product(+)-Cis-phenothrin
CAS:Cis-phenothrin is a carbamate insecticide that is used in agriculture, public health, and veterinary medicine. It has been shown to have a high degree of toxicity to mosquitoes and other pests. Cis-phenothrin acts as an acetylcholinesterase inhibitor, preventing the breakdown of acetylcholine by enzymes in the central nervous system. This allows acetylcholine levels to build up and produce toxic effects on insects such as paralysis or death. Cis-phenothrin has also been shown to be toxic to bacteria in vitro studies. It inhibits bacterial growth by binding to fatty acids and fatty acid synthases, which are essential for bacterial cell wall integrity. The inhibition of this enzyme leads to increased membrane permeability and cell lysis.
