The mechanism of action for this drug is not well understood, but it may be due to its ability to bind with monoclonal antibodies and enter kidney cells by passive diffusion.</p>Formule :C5H9BrO2Degré de pureté :Min. 95%Couleur et forme :Clear LiquidMasse moléculaire :181.03 g/mol3’-Azido-3’-deoxyguanosine

CAS :<p>4-Bromo-2-chlorocinnamic acid is a useful chemical in the synthesis of organic compounds. It is an intermediate in the production of pharmaceuticals and other organic compounds. The compound has been used as a research chemical and as a building block for the production of complex chemicals. 4-Bromo-2-chlorocinnamic acid has also been used as a building block for the production of fine chemicals, such as dyes, perfumes, and pesticides.</p>Formule :C9H6BrClO2Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :261.5 g/molErythropoietin
CAS :<p>Erythropoietin is a glycoprotein hormone, which is primarily produced by interstitial fibroblasts in the kidney in response to hypoxia. Its main mode of action involves binding to erythropoietin receptors on the surface of erythroid progenitor cells in the bone marrow, thereby initiating a signaling cascade that results in the proliferation and differentiation of these progenitors into mature red blood cells.</p>Degré de pureté :(Capillary Zone Electrophoresis) Min. 98.0%Couleur et forme :Powder3-Ethoxycinnamic acid
CAS :<p>3-Ethoxycinnamic acid is a polyhydric alcohol that has been shown to inhibit the growth of various microorganisms. 3-Ethoxycinnamic acid inhibits the growth of microorganisms by binding to the alkenyl groups in the cell membrane, thereby preventing them from synthesizing their own fatty acids. The binding of 3-ethoxycinnamic acid to alkali metal ions also prevents their uptake into the cell, which leads to an accumulation of these ions outside the cell and eventually results in cell death. 3-Ethoxycinnamic acid is soluble in water and may be used as a stain or quaternary ammonium compound.</p>Formule :C11H12O3Degré de pureté :Min. 95%Couleur et forme :SolidMasse moléculaire :192.21 g/mol2'-Hydroxyacetophenone
CAS :<p>2'-Hydroxyacetophenone is a hydroxylated acetophenone derivative. It is used in the synthesis of coumarin derivatives, which are used as pharmaceuticals and natural compounds. 2'-Hydroxyacetophenone has been found to be cytotoxic against HL-60 cells, which is a line of leukemia cells in humans. It also has anti-cancer properties that may be due to its ability to inhibit water vapor and nitrogen gas release from cervical cancer cells. The structural analysis of 2'-hydroxyacetophenone has shown that it contains an intramolecular hydrogen bond with the proton on the oxygen atom. This bond is responsible for stabilizing the molecule's structure and maintaining its 3D geometry.</p>Formule :C8H8O2Degré de pureté :Min. 95%Couleur et forme :Clear LiquidMasse moléculaire :136.15 g/mol
