CAS :<p>N-(6-Phenylhexyl)-5-chloro-1-naphthalenesulfonamide is a dibutyryl camp analog that has been shown to inhibit the L-type calcium channel in a dose-dependent manner. It has an effect on both spermatozoa and glioma cells, with its most significant effect being inhibition of the intracellular calcium ion. This drug inhibits the growth rate of these cells, which may be due to its ability to activate adrenergic receptors and cause increased intracellular calcium ion levels. N-(6-Phenylhexyl)-5-chloro-1-naphthalenesulfonamide also slows the cycle of the cell, which may be due to a kinetic effect.</p>Formule :C22H24ClNO2SDegré de pureté :Min. 95%Masse moléculaire :401.95 g/molδ-Hexalactone
CAS :<p>Delta hexalactone is a fatty acid that has been shown to have antagonistic properties against bacterial growth. It has been tested for its antibacterial activity and shown to be active against human pathogens, including mycobacterium. Delta hexalactone is also used as an analytical method in order to detect the presence of glycol ethers.</p>Formule :C6H10O2Degré de pureté :Min. 95%Couleur et forme :Clear LiquidMasse moléculaire :114.14 g/mol3,4'-Dihexyl-2,2'-bithiophene

CAS :2,6-Dibromo-3-nitropyridine is a chemical compound that has been shown to inhibit serine protease activity. The compound was shown to be an inhibitor of the enzyme trypsin, and showed some activity against a number of other proteases. 2,6-Dibromo-3-nitropyridine has also been shown to inhibit nucleophilic alkylation of DNA bases by 2,6-dichloroquinoxaline. 2,6-Dibromo-3-nitropyridine is a targeted inhibitor that binds to the active site of the enzyme and prevents the formation of an enzyme-substrate complex. This inhibition leads to a decrease in the production of proteins essential for cell division.Formule :C5H2Br2N2O2Degré de pureté :Min. 95%Masse moléculaire :281.89 g/mol(-)-B-Chlorodiisopinocampheylborane, 60% in Hexane, ca. 1.7mol/L
CAS :(-)-B-Chlorodiisopinocampheylborane is a carbonyl group that can be used for asymmetric synthesis. It was synthesized from the reaction of chlorodiisopinocampheylborane with butyllithium and allyl bromide, followed by aqueous workup. The enantiomers were separated through thin layer chromatography on silica gel plates with hexane as the eluent. The resolution of racemic latanoprost lactol was achieved in the same manner. (-)-B-Chlorodiisopinocampheylborane is also a diketone that can be prepared from para-chloroacetophenone and sodium hydroxide in ethanol. This diketone undergoes an intramolecular cyclization to produce noradrenaline (norepinephrine) and hydrochloric acid, which can then be converted into dioxolanes or other products.Formule :C20H34BClDegré de pureté :Min. 95%Couleur et forme :Clear LiquidMasse moléculaire :320.75 g/mol
