Discontinued product4-chloropyridine-3-sulfonyl chloride
CAS:4-Chloropyridine-3-sulfonyl chloride is a thrombin inhibitor that has been discovered through the use of in vitro screening methods. It is a small molecule with lipophilic properties and oral bioavailability. This compound inhibits thrombin by binding to the active site of the enzyme, which prevents the formation of an enzyme-thrombin complex. The discovery was made using a pharmacophore-based approach and further modifications were made to improve its potency and increase its lipophilicity. This compound also exhibits an acceptable level of bioavailability in vivo, which may be due to its high solubility in water.Formula:C5H3Cl2NO2SPurity:Min. 95%Molecular weight:212.1 g/molRef: 3D-IBA26344

Discontinued productVinyltributyltin
CAS:Controlled ProductVinyltributyltin is a dibutyltin oxide (DBTO) enantiomer that has been shown to inhibit the HIV-1 protease. Vinyltributyltin has also been shown to reduce inflammation in bowel disease, as well as to have synergistic effects with other drugs in the treatment of cancer and inflammatory bowel disease. The mechanism of action of vinyltributyltin is not yet known, but it may be related to its ability to inhibit the quinazolone-dependent formation of reactive oxygen species. Vinyltributyltin also inhibits the NS3 protease, which is an enzyme involved in hepatitis C virus replication.

Discontinued productPiperyline
CAS:Piperyline is an alkanoic acid that has shown to be effective against skin cancer. It also has antimicrobial properties, which may be due to its ability to bind metal ions and form polymeric compounds. Piperyline inhibits microbial growth by inhibiting the synthesis of proteins and nucleic acids. The antimicrobial activity is related to its cationic polymerization with hydroxyl groups, which forms a structure that can inhibit microbial enzymes and disrupt microbial cell membranes. This compound also interacts with the skin's natural lipids, making it difficult for microorganisms to attach and grow on the skin. Piperyline is synthesized in organic chemistry laboratories as an amide precursor of other pharmaceuticals such as penicillin.
