  • rac-Keto labetalol

    CAS:

    Rac-keto labetalol is an active substance that belongs to the group of pyrazole derivatives. It is a racemic mixture of two enantiomers, (+)-labetalol and (-)-labetalol. Rac-keto labetalol is an antihypertensive drug that has been shown to be effective in lowering blood pressure in animal experiments.

  • [5-L-Aspartic Acid]-desmopressin


    Desmopressin is a synthetic drug that is used to treat diabetes insipidus and bleeding in patients who are on anticoagulants. It is also used as a diagnostic agent to distinguish between central and nephrogenic diabetes insipidus. Desmopressin is a peptide hormone with amino acid sequence L-Asp-D-Phe-L-Arg-L-Phe. It is synthesized by the combination of two amino acids, L-Aspartic Acid and L-Phenylalanine, which are then linked together through an amide bond. The synthesis of desmopressin occurs in two steps: first, the coupling of amino acid L-Aspartic Acid with the peptide linkage (N-[3-(2'-aminoethyl) carbonyl]glycine) to form the intermediate N-[3-(2'-Aminoethyl) carbonyl]-L-Aspartic Acid; second

  • (+)-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.
