5a-Pregnane-3a,20a-diol
CAS:Producto controlado5a-Pregnane-3a,20a-diol is a gamma-aminobutyric acid (GABA) analogue that is used in the treatment of women with variegated hyperpigmentation. It has inhibitory properties on mutant enzymes such as disulfate reductase and other enzymes involved in the synthesis of prostaglandins. The drug binds to the enzyme GABA transaminase and this binding prevents the formation of GABA from glutamate. 5a-Pregnane-3a,20a-diol also inhibits the synthesis of prostaglandin E2 by binding to cyclooxygenase 2, leading to decreased inflammation and pain. 5a-Pregnane-3a,20a-diol is metabolized by glucuronidation or sulfation and excreted into bile or urine. This drug can also be hydrolyzed by dehydrogenases or other enzymes such as esterases.Fórmula:C21H36O2Pureza:Min. 95%Peso molecular:320.51 g/molEstrone 3-valerate

CAS:Bromocresol purple sodium salt is a dye that emits light when it is irradiated with light of a particular wavelength. It has been used to detect amniotic fluid contamination in the laboratory and as an absorber in polymer films. Bromocresol purple sodium salt absorbs ultraviolet and visible light, which causes it to emit red light. The molecules of bromocresol purple sodium salt are long-chain triazoles, which absorb water vapor and emit infrared radiation. This property can be used to detect the presence of alkali metals. The luminescent property of bromocresol purple sodium salt can be enhanced by adding an alkali metal, such as potassium or lithium chloride, to the solution where it is dissolved.

CAS:Producto controladoDelta6-Testosterone is a natural steroid hormone that belongs to the group of steroid drugs. It is a potent androgen, or male sex hormone, which stimulates the development and maintenance of male sexual characteristics, including the growth of prostate gland and seminal vesicles. The effects of Delta6-testosterone are mediated by binding to and activating the Androgen Receptor (AR). The effects may also be increased when Delta6-testosterone binds to AR in combination with other hormones such as estradiol. Delta6-Testosterone is metabolized by the liver into testosterone through the cytochrome p450 enzyme system. This process begins with conversion of Delta6-testosterone into 6alpha-dihydrotestosterone (DHT) by 5a-reductase. DHT can then be converted into testosterone by 3beta-hydroxysteroid dehydrogenase/3alpha-hydroxysteroid dehydrogenase (3betaHSD) or 17beta hydFórmula:C19H26O2Pureza:Min. 95%Peso molecular:286.41 g/mol22α-Hydroxy cholesterol
CAS:Producto controlado22a-Hydroxycholesterol is a naturally occurring, oxygenated cholesterol metabolite. It binds to the transcriptional coactivator retinoid X receptor (RXR) and inhibits the activity of certain liver enzymes. 22a-Hydroxycholesterol has been shown to have toxic effects on mouse tumors and to inhibit the production of ATP in vitro. 22a-Hydoxycholesterol also inhibits the function of ATP binding cassette (ABC) transporter proteins, which are involved in cholesterol transport from cells. The long-term toxicity of 22a-hydroxycholesterol is not well understood, although it has been shown that this metabolite can induce autoimmune diseases in rats.Fórmula:C27H46O2Pureza:Min. 95%Peso molecular:402.65 g/molWhiskey lactone
CAS:Whiskey lactone is an organic compound that belongs to the class of lactones. This sample preparation technique employs a solution of sodium hydroxide that acts as an extractant. The hydroxide solution reacts with the acidic ph of the sample, which causes hydrolysis and esterification of the fatty acid chains in the sample. The reaction is accompanied by a color change from yellow to blue. Whiskey lactone has been shown to have high values for eugenol and chemical structures such as isovaleric acid and hydroxyl group.

CAS:Eltrombopag olamine is an orally active drug that belongs to the class of thiazolidinones. It has been used for the treatment of thrombocytopenia in patients with chronic liver disease and myelodysplastic syndrome. Eltrombopag olamine inhibits platelet aggregation by binding to glycoprotein IIb/IIIa receptors on the surface of platelets. The drug is a prodrug that is metabolized in vivo to its active form, eltrombopag. This conversion is catalysed by CYP3A4 and CYP2D6 enzymes and can be inhibited by drugs that inhibit these enzymes, such as trifluoroacetic acid and hydroxyl group-containing compounds. Eltrombopag olamine binds to erythrocytes, which may be due to its ability to form intramolecular hydrogen bonds with nitrogen atoms.

CAS:1-(2-Nitrophenyl)-1,2-ethanediol is a chemical that has been shown to inhibit the glutamate-induced increase in cytosolic Ca2+ concentration. It also prevents the loss of membrane integrity and protects against cell death by inhibiting apoptosis. 1-(2-Nitrophenyl)-1,2-ethanediol also inhibits amp-activated protein kinase activity and increases ATP production. These effects may be due to its ability to reduce intracellular Ca2+ levels and prevent Ca2+ overload in mitochondria. 1-(2-Nitrophenyl)-1,2-ethanediol has been shown to have a protective effect on isolated heart cells and ventricular myocytes from hypoxia/reoxygenation injury and is an effective model system for investigating biochemical properties of glutamate excitotoxicity.Fórmula:C8H9NO4Pureza:Min. 95%Forma y color:PowderPeso molecular:183.16 g/molGibberellic acid methyl ester
