Cholesterol propionate
CAS:Producto controladoCholesterol Propionate is a monolayer film-forming polymer that forms a polymeric matrix when combined with water. The thermal expansion of this material is dependent on the concentration of cholesterol propionate and can be used as a target tissue for multi-walled carbon nanotubes (MWCNTs). In addition, Cholesterol Propionate has been shown to have light emission properties due to its hydroxyl group and fatty acid content. The phase transition temperature of the material is dependent on the concentration of benzoate in the formulation. When it reaches the phase transition temperature, cholesteryl benzoate undergoes a phase change from crystalline to liquid at room temperature. This property can be used to activate MWCNTs within Cholesterol Propionate films, which then emit light.
Fórmula:C30H50O2Pureza:Min. 95%Peso molecular:442.7 g/mol22β-Hydroxy cholesterol
CAS:Producto controlado22-Hydroxycholesterol is a product of cholesterol synthesis, which is formed by the side-chain cleavage of cholesterol. This compound has been shown to inhibit cholesterol acyltransferase and to be cytotoxic in vitro. 22-Hydroxycholesterol has also been shown to have an inhibitory effect on protein synthesis and on the activity of forskolin, an activator of adenylate cyclase that is involved in the regulation of cellular levels of cAMP. The antioxidant properties of 22-hydoxycholesterol may be due to its chemical structure, which includes a hydroxyl group. This compound also shows an insulin-sensitizing effect in mice fed a high fat diet.Fórmula:C27H46O2Pureza:Min. 95%Peso molecular:402.65 g/molDelta9,11-Dehydro-17b-estradiol 17-valerate

CAS:2,6-Dichloro-5-nitropyrimidin-4-amine is a chlorinating agent that reacts with aliphatic and aromatic amines to form substituted pyrimidines. The substitution pattern of the product depends on the regioselectivity of the reaction. 2,6-Dichloro-5-nitropyrimidin-4-amine is one of the few chlorinating agents that react with propylamine. Substitution at position 2 of the purine ring has been found to be more selective than substitution at position 6. The 2,6-dichloropyrimidine can also be used as a nitro group source in chemical synthesis or as an intermediate in production of other compounds.

CAS:All-trans-retinol is a form of vitamin A that is found in many animal tissues and some plant oils. It acts as a hormone, binding to the retinoic acid receptors (RARs) in the nucleus and activating gene transcription. All-trans-retinol has been shown to be effective against hyperproliferative diseases such as cancer, both by inducing apoptosis and by inhibiting cell growth. All-trans-retinol may also have therapeutic potential for other diseases, such as intestinal cancers and prostatic hypertrophy. This compound has been shown to induce messenger RNA (mRNA) production in cells that express RARs.
Fórmula:C20H30OPureza:Min. 95%Peso molecular:286.45 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/molThymosin beta10 (human, rat)

CAS:Producto controlado(-)-cis-Pentazocine is a kappa-opioid receptor agonist that has been used for the treatment of pain, cough, and diarrhea. It is also used to treat withdrawal symptoms in those who are addicted to other narcotic drugs. The drug binds to the κ-opioid receptors and activates G protein coupled receptors. When this occurs, it inhibits the release of neurotransmitters from nerve cells in the brain, which reduces pain and causes sedation. Pentazocine can cause side effects such as dizziness, constipation, nausea, vomiting, headache, blurred vision, anxiety and depression. These side effects are more common with high doses or when pentazocine is taken with other drugs that have similar effects.
