Pureza:Min. 95%all-trans-13,14-Dihydro retinol
CAS:Retinol is a form of vitamin A that is used for the treatment of insulin resistance. It can be synthesized by the body from all-trans-retinol, which is found in many animal and plant sources. Retinol can also be obtained from supplements, although it is poorly absorbed by the body. Retinol has been shown to improve insulin sensitivity in a cell culture model system, as well as in wild-type mice with diabetes mellitus. This drug has been shown to have strong anti-inflammatory effects and may also be useful for the treatment of hepatic steatosis. Retinol binds competitively to cellular retinoic acid receptors, leading to transcriptional activation of target genes, such as those involved in fatty acid metabolism.Fórmula:C20H32OPureza:Min. 95 Area-%Forma y color:Clear Viscous LiquidPeso molecular:288.47 g/mol22α-Hydroxy cholesterol
CAS:Producto controlado22a-Hydroxycholesterol is a naturally occurring, oxygenated cholesterol metabolite.

CAS:Producto controladoTibolone is a synthetic hormone that is used in the treatment of menopausal symptoms and breast cancer. Tibolone has been shown to be an effective treatment for menopausal symptoms, such as hot flashes and vaginal dryness, by providing relief from these symptoms. Tibolone has also been shown to have anti-cancer effects. This drug may be useful for treating breast cancer because it can inhibit the growth of cancer cells by binding to estrogen receptors and blocking estrogen-induced cell proliferation. Tibolone also stimulates angiogenesis, which is the formation of new blood vessels in order to provide nutrients and oxygen to growing tissue. It has been shown that this drug inhibits the synthesis of hepg2 cells in vitro, which are involved in the production of angiogenic factors. Tibolone may also have clinical relevance as a chemopreventive agent against prostate cancer.BR> Tibolone has also been shown to stimulate sulphatase activity in vitro, which may contribute to

Fórmula:C36H39FN2O5Pureza:Min. 95%Peso molecular:598.7 g/mol4'-Hydroxy atomoxetine
CAS:4'-Hydroxyatomoxetine is a metabolite of atomoxetine, which is a drug that is used to treat attention deficit hyperactivity disorder and narcolepsy. 4'-Hydroxyatomoxetine has been shown to have pharmacological properties similar to those of atomoxetine. However, it does not bind to the κ-opioid receptors, unlike its parent drug. The analytical method for this metabolite has been developed using liquid chromatography with tandem mass spectrometry. The major limitation with the analytical method is that it can be affected by matrix effects and hepatic impairment. This metabolite is glucuronidated and then conjugated with trifluoroacetic acid (TFA) before excretion in urine or bile. It also binds to kappa-opioid receptors, but at a lower affinity than its parent compound.Fórmula:C17H21NO2Pureza:Min. 95%Forma y color:PowderPeso molecular:271.35 g/mol9-cisRetinol
CAS:9-cisRetinol is a form of vitamin A that plays an important role in the synthesis of lipids and proteins.
