CAS :Produit contrôléRotigotine is a drug that is used to treat Parkinson's disease. It is a dopamine agonist that stimulates the release of dopamine in the brain. Rotigotine has been shown to be effective in controlling symptoms of Parkinson's disease, such as tremors and stiffness, and improving motor skills. This drug has also been shown to have a good tolerability profile, with few side effects reported. Rotigotine is rapidly absorbed from the gastrointestinal tract and metabolized by CYP2D6 into desalkyl rotigotine, which are pharmacologically inactive compounds. The mean terminal half-life for rotigotine is about 2 hours.

CAS :Produit contrôlé1,2,3,4-Tetrahydronaphthalen-2-amine hydrobromide (THNA) is an amine that inhibits the enzyme tyrosine hydroxylase. This inhibition leads to a decrease in the synthesis of dopamine and norepinephrine. THNA has been shown to have inhibitory properties on locomotor activity, acid complex formation, and aminotransferases. It also exhibits receptor binding and agonist binding site activity. One study found that THNA had no effect on rat striatal tissue. The drug has been shown to be effective in metabolic disorders such as obesity.
Formule :C10H13NDegré de pureté :Min. 95%Masse moléculaire :147.22 g/mol6-Hydroxy oxymorphone
CAS :Produit contrôléOxymorphone is a potent synthetic opioid analgesic with a short duration of action. It is a prodrug that has to be metabolized in the liver by cytochrome P450 enzymes for activation. The 6-hydroxy metabolite is more potent than oxymorphone itself and has been shown to have antinociceptive properties in mice. Oxymorphone is used in cancer patients as an oral dosage form, which may be administered with or without food. It has been shown that the albumin concentration influences the pharmacokinetics of oxymorphone and its metabolites. This drug also has immunomodulatory effects and can cause adverse events such as hypersensitivity reactions, nausea, vomiting, or constipation.Formule :C17H21NO4Degré de pureté :Min. 95%Masse moléculaire :303.35 g/molCholesterol Heptanoate
CAS :Produit contrôléCholesterol Heptanoate is a liquid crystal composition that is used to coat tablets. It is also used for the diagnosis of fatty acid metabolism and atherosclerotic lesion formation by measuring the fatty acid composition of body tissues. Cholesterol Heptanoate can be used to form polymeric matrices for use in drug delivery systems. These matrices are composed of ionizable, film-forming polymers with excipients that have phase transition temperatures near 37°C.
Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :498.82 g/mol(S)-3',5'-Bis(trifluoromethyl)-1-phenethanol
CAS :(S)-3',5'-Bis(trifluoromethyl)-1-phenethanol is a choline derivative that is used in the treatment of liver cancer. It has been shown to increase the permeability of cell membranes and to suppress the growth of tumor cells by inhibiting protein synthesis. (S)-3',5'-Bis(trifluoromethyl)-1-phenethanol can be used as a surfactant and a hydrophobic solvent for optimization of reaction parameters. This chemical also has been shown to be active against Gram-positive bacteria such as Staphylococcus aureus and Enterococcus faecalis, but not against Gram-negative bacteria such as Escherichia coli or Pseudomonas aeruginosa. The mechanism of this effect is mediated by chloride ions that act as bioreductive agents on cellular membranes, leading to increased permeability and cell death.
Formule :C10H8F6ODegré de pureté :Min. 95%Masse moléculaire :258.16 g/mol7b-Hydroxy cholesterol 3b-acetate
CAS :Produit contrôlé7b-Hydroxy cholesterol 3b-acetate is an allylic compound that is catalyzed by molybdenum, which eliminates the acetyl group at position 7 to form a double bond with the 3-position. The reaction temperature of 7b-hydroxy cholesterol 3b-acetate can be increased to high temperatures (i.e., >100°C) for the elimination process, and allylic acetates are obtained as products. The reaction starts with the addition of hexacarbonyl, which leads to a diene intermediate. This is then eliminated by adding acetamide in presence of high concentration of acetic acid and catalytic amounts of molybdenum. The low yield and efficiency, however, are major drawbacks of this process.Formule :C29H48O3Degré de pureté :Min. 95%Masse moléculaire :444.69 g/molN-[(3R)-1-(3,3-Dimethyl-2-oxobutyl)-2,3-dihydro-2-oxo-5-(2-pyridinyl)-1H-1,4-benzodiazepin-3-yl]-N'-[3-(methylamino)phenyl]urea
CAS :Produit contrôléN-[(3R)-1-(3,3-Dimethyl-2-oxobutyl)-2,3-dihydro-2-oxo-5-(2-pyridinyl)-1H-1,4-benzodiazepin-3-yl]-N'-[3-(methylamino)phenyl]urea (GZ4081) is a drug that inhibits gastrin secretion by blocking the G protein coupled receptor. It has been shown to be effective in treating cancer and also has an inhibitory effect on tissue samples. GZ4081 has been shown to have long term treatment effects as well as being effective for prognosis. The effective dose of GZ4081 is not yet known but it is believed to be at least 10 times lower than the doses used for other drugs in its class.Formule :C28H30N6O3Degré de pureté :Min. 95%Masse moléculaire :498.58 g/mol1-Hexyl-3-(1-naphthoyl)pyrrole

CAS :3-Methylglutaric acid is an organic compound that belongs to the group of alkanocarboxylic acids. It has been shown to reduce the formation of malonic acid, which can be toxic to the heart and cause congestive heart failure. 3-Methylglutaric acid also inhibits oxidation catalysts and increases the production of energy in cells by providing electrons. The kinetic data for 3-methylglutaric acid have been determined using a gas chromatography technique on a high-temperature conversion reactor at a pH of 7.0 with a concentration of 0.1 M potassium phosphate buffer (pH 7) and a temperature of 70°C. 3-Methylglutaric acid has been shown to inhibit monoclonal antibody cationic polymerization, which may be due to its reactive nature and its ability to donate hydrogen ions or electrons.
Formule :C6H10O4Degré de pureté :Min. 95%Masse moléculaire :146.14 g/mol2,6-Dibromo-3-nitropyridine
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/mol2-Dehydro-3-methoxy tibolone
