CAS:Piperazine-1-sulfonamide is a protein inhibitor that belongs to the group of regulatory agents. It is used to regulate the growth of various types of cells, including immune cells and smooth muscle cells. Piperazine-1-sulfonamide has been shown to inhibit chemokine receptor activity in inflammatory bowel disease, which may be due to its ability to inhibit CXCR4 and CCR5 receptors. This drug also inhibits dpp-iv, an enzyme involved in protein degradation. The pharmacokinetic properties of this agent are not well studied, but it does show toxicity studies in rats at higher doses. Piperazine-1-sulfonamide can cause congestive heart failure and liver damage at high doses, so it should not be used for prolonged periods of time.

Discontinued product3-Iododibenzofuran
CAS:3-Iododibenzofuran is a fluorescent compound that has been used as a probe for the study of neutral endopeptidase activity. The compound is characterized by a high degree of thermal stability and an inhibitory potency at pH 7.0 that is approximately 3 orders of magnitude greater than that of the active site inhibitor, anthracene. 3-Iododibenzofuran can be synthesized using chemoenzymatic methods, with efficiencies and profiles that are similar to those obtained in the conventional method. This probe can also be used to investigate the functional role of proteins in living cells or tissues.
3-Iodobenzofuran has been shown to have pressor effects in rats and can cause tetrazole (a type of explosive) to detonate when heated, which makes it unsuitable for use in devices such as explosives or pyrotechnics.Formula:C12H7IOPurity:Min. 95%Molecular weight:294.09 g/molRef: 3D-FAA89629

Discontinued product2-Chloro-6-(chloromethyl)pyridine
CAS:2-Chloro-6-(chloromethyl)pyridine (2C6CP) is a chloride precursor that can be used for the synthesis of metal chlorides, such as copper chlorides. 2C6CP is synthesized by reacting thionyl chloride with the substituted pyridine under anhydrous conditions at -78°C. The resultant 2C6CP is then hydrolyzed to produce the desired chloride.
2C6CP has been shown to act as a ligand in coordination chemistry. It was first synthesized by reacting 3-chloropyridine with thionyl chloride and then hydrolyzing it to 2-chloropyridine. This method was later modified to use 4-chlorobenzoyl chloride instead of 3-chloropyridine, producing 2,4-dichloropyridine.Formula:C6H5Cl2NPurity:Min. 95%Molecular weight:162.02 g/molRef: 3D-DDA84688

CAS:3-Chlorophenylurea is a quinazolinone that inhibits the growth of candida glabrata. This compound has been shown to inhibit efflux pumps, which are proteins that pump out drugs from the cell. 3-Chlorophenylurea has been shown to inhibit the efflux of fluconazole, a drug used to treat fungal infections, and thiourea, a compound that is known for its cytotoxicity. The inhibition of these two compounds suggests that 3-chlorophenylurea could be an efflux pump inhibitor.
Formula:C7H7ClN2OPurity:Min. 95%Molecular weight:170.6 g/mol2,5-Dihydroxyterephthalaldehyde
CAS:2,5-Dihydroxyterephthalaldehyde (2,5-DTPA) is a sugar alcohol that is used in the production of polyester. It can be synthesized by electrochemical methods and is produced as an intermediate in the synthesis of 2,5-dihydroxypentane-1,5-diyldimethanol. The optical properties and chemical stability of 2,5-DTPA are determined by its protonation state. The protonation state depends on the pH of the solution or solvent. 2,5-DTPA has two isomers: one with an intramolecular hydrogen bond and one without. 2,5-DTPA also exists as an enol form at high pH values and as a keto form at low pH values. This compound has been shown to have liver protective effects against cell death induced by oxidative stress in animal models.

Discontinued product5-Fluoro-2-nitrobenzoyl chloride
CAS:5-Fluoro-2-nitrobenzoyl chloride is a conformationally locked macrocyclic compound that has been synthesized by solid phase synthesis. It is found in two conformational states and can be made to switch between these two states by applying a force to the molecule. This conformation can be controlled by changing the side chain of 5-fluoro-2-nitrobenzoyl chloride, which can be done experimentally. The conformational behavior of this macrocycle was studied using molecular dynamics simulations and it was found that there are four possible conformations for the molecule. The conformations with different side chains were found to have different energies, which could be used as a measure of their relative stability.

CAS:Controlled Product2-Bromo-3,3,3-trifluoro-1-propene is a chemical compound that has been synthesized in an asymmetric reaction. The reactant is bromopropane and the product is 2,2,2-trifluoropropene. The methylene group on the propene molecule is activated by the nucleophilic attack of a fluoride ion from hydrogen fluoride to form a cavity with a highly strained bond. The kinetic study of this reaction revealed that the activation energy for the reaction is 42 kJ/mol. Palladium-catalyzed coupling reactions are catalyzed by palladium and require nonpolar solvents such as toluene or dichloromethane. This type of reaction has been shown to be exothermic with an isolated yield of 1%.

CAS:3-Hydroxy-5-methylpyridine (3HMP) is a chemical substance that has been classified as an amine. It is a product of the metabolism of purines, which are nitrogenous bases found in DNA and RNA. 3HMP is produced by aerogenic bacteria (such as Enterobacter), and can be used to estimate the number of these bacteria present in water samples. 3HMP has been shown to have antiviral properties against influenza virus, and can be used as a biomarker for the presence of other viruses in animals. 3HMP also has mineralization properties, which have been studied extensively, particularly with regards to pancreatic disease.

CAS:4,5-Dihydroxy-2,3-pentanedione is a carbonyl compound that is the product of the oxidation of ascorbic acid. It is used in wastewater treatment and has antimicrobial properties against infectious diseases. This compound has been shown to inhibit protein synthesis by binding to the ribosome and preventing the formation of peptide bonds between amino acids. 4,5-Dihydroxy-2,3-pentanedione has also been shown to bind to plasma proteins, which may be due to its acyl chain structure. 4,5-Dihydroxy-2,3-pentanedione can be synthesized in a catalytic mechanism that involves dehydroascorbic acid and molecular oxygen.

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.
