Antibody conjugates of N2'-Deacetyl-N2'-(3-mercapto-1-oxopropyl)-maytansine and the murine monoclonal antibody TA. 1, using linkers containing either a disulfide bond or a thioether bond, have been synthesised. These antibody conjugates bind to the HER-2/new oncogene protein that is expressed on human breast tumor cells.Formule :C35H48ClN3O10SDegré de pureté :Min. 95%Couleur et forme :White Off-White Yellow PowderMasse moléculaire :738.29 g/mol7-Amino-4-methylcoumarin

CAS :<p>Alpha-methylhydrocinnamic acid (AMHA) is a synthetic enantiomer of 2-phenylbutyric acid, which has been shown to inhibit the growth of k562 cells. It is also a substrate for fatty acid synthase and may play an important role in fatty acid metabolism. AMHA has been shown to inhibit the production of reactive oxygen species by phagocytic cells exposed to ionizing radiation, which may be due to its ability to scavenge hydroxyl radicals. The effect of AMHA on hematopoietic cells, including neutrophils and bone marrow cells, has not yet been determined.</p>Formule :C10H12O2Degré de pureté :Min. 95%Couleur et forme :White Clear LiquidMasse moléculaire :164.2 g/mol4-Iodo-2-methoxybenzoic acid methyl ester
CAS :<p>4-Iodo-2-methoxybenzoic acid methyl ester is a high quality chemical that can be used as a versatile building block in chemical synthesis. It is a complex compound that has been shown to be an effective reagent for research, which can be used in the synthesis of new complex compounds. 4-Iodo-2-methoxybenzoic acid methyl ester is also useful as an intermediate or reaction component in organic syntheses. This chemical is available for purchase at a CAS number of 148490-97-5.</p>Formule :C9H9IO3Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :292.07 g/molO-Cresolphthalein
CAS :<p>O-Cresolphthalein is a gadolinium chelate that is used as a contrast agent for magnetic resonance imaging (MRI) of the brain, spine, and joints. The gadolinium ion is bound to the cresol molecule, which has an attached hydroxyl group. This complex attaches to the phosphorous pentoxide and creates a precipitate of metal hydroxides in the presence of water and sodium carbonate. O-Cresolphthalein is also used in clinical pathology to measure glomerular filtration rate (GFR), which is important for diagnosing renal disease. MRI scans are used to diagnose osteogenic genes that are associated with bone diseases such as osteoporosis.</p>Formule :C22H18O4Degré de pureté :Min. 95 Area-%Couleur et forme :PowderMasse moléculaire :346.38 g/molAtorvastatin ethyl ester
CAS :<p>Atorvastatin ethyl ester is a prodrug of atorvastatin that is used for the treatment of hypercholesterolemia. It inhibits HMG-CoA reductase, which reduces cholesterol production in the liver. The permeation rate of atorvastatin ethyl ester is increased by coadministration with c1-c10 fatty acids, which can be achieved by taking it with food. Atorvastatin ethyl ester has been shown to have antithrombotic and anti-inflammatory effects, which are due to its inhibition of the synthesis of thromboxane A2 and prostaglandin E2. Atorvastatin also inhibits protein synthesis in some cells, such as hepatocytes and neutrophils, but not in others such as fibroblasts or platelets. This may be related to the expression of an enzyme called cytosolic phospholipase A2 (cPLA2).</p>Formule :C35H39FN2O5Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :586.69 g/molAlbopilosin A

CAS :<p>22-Fluorovitamin D3 is a synthetic analog of vitamin D3, which is derived from chemical synthesis involving fluorination at the C-22 position. This modification results in a compound that mimics the structure and activity of naturally occurring vitamin D3 but with altered pharmacokinetics and metabolic stability. The fluorine atom, due to its size and electronegativity, influences the binding affinity and activity of the compound at vitamin D receptors.</p>Formule :C27H43FODegré de pureté :Min. 95%Masse moléculaire :402.63 g/mol5-Methyl-2-nitrophenol
CAS :<p>5-Methyl-2-nitrophenol is a phytotoxic chemical that is used as a synthetic intermediate in organic chemistry. It has been shown to have a high bioconcentration factor and can be found in wastewater. The major use of 5-methyl-2-nitrophenol is the synthesis of 2,4,6-trinitrophenylhydrazine (TNP) which is used as an analytical reagent for the determination of nitrates. The reaction mechanism of 5-methyl-2-nitrophenol involves intramolecular hydrogen transfer from the methylene group to the nitro group and subsequent elimination of HCl.
