The product can also be obtained from 2,4,6-trinitrophenol and NBS. 3-BNP has shown chemoselectivity for chlorides relative to iodides or fluorides. The yields are higher when it is used in coupling reactions and permutations with lithium or magnesium.Formule :C6H4BrNO3Degré de pureté :Min. 95%Masse moléculaire :218 g/mol20a-Hydroxy cholesterol
CAS :Produit contrôlé<p>20a-Hydroxy cholesterol is a model system for studying the effects of hydroxylation on fatty acid metabolism. The addition of one hydroxyl group to the 20 carbon position in cholesterol leads to an analog, 20a-hydroxycholesterol. This compound has been shown to inhibit the enzyme activities of 3-hydroxyacyl coenzyme A dehydrogenase and acyl coenzyme A:cholesterol acyltransferase. The inhibition of these enzymes leads to decreased production of both prostaglandin E2 and leukotriene B4, which are pro-inflammatory mediators. 20a-Hydroxycholesterol has also been found to be effective in treating skin cancer and adrenocortical carcinoma by inhibiting lipid synthesis, thereby reducing cell proliferation rates.</p>Formule :C27H46O2Degré de pureté :Min. 95%Masse moléculaire :402.65 g/mol12-Amino-1-dodecanoic acid methyl ester hydrochloride salt
CAS :<p>12-Amino-1-dodecanoic acid methyl ester hydrochloride salt (12ADM) has been shown to have immunomodulatory properties. It has a nanomolar range of activity, which is the optimal for an immunosuppressant. 12ADM inhibits the transcriptional activity of human immunodeficiency virus type 1 (HIV-1) and HIV-2, as well as other retroviruses, through interactions with specific RNA sequences in the viral genome. The amide group in this compound is essential for its antiviral activity, and it also interacts with betulinic acid to enhance its cytotoxicity.</p>Formule :C13H28ClNO2Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :265.82 g/mol20-Epipregnantriol
CAS :Produit contrôlé20-Epipregnantriol is a natural metabolite of pregnancy, which is a mixture of 20-hydroxyprogesterone, 17-hydroxyprogesterone, and pregnanediol. This hormone has been shown to be produced in the testes and ovaries. It stimulates the production of estrogen by the ovaries and may have an effect on inhibiting testosterone production in the testes. 20-Epipregnantriol has been used as an analytical control in studies on steroidogenesis.Formule :C21H36O3Degré de pureté :Min. 95%Masse moléculaire :336.51 g/mol20-Dehydro cholesterol 3-acetate
