1-(3,4-Methylenedioxyphenyl) 2-nitropropene
CAS :1-(3,4-Methylenedioxyphenyl) 2-nitropropene (1-MPNP) is a phosphatase inhibitor that is active against gram-negative bacteria by inhibiting enterotoxins and chlamydia. 1-MPNP inhibits the activity of tyrosine phosphatases, which are enzymes that play a major role in bacterial virulence. 1-MPNP competitively inhibits the activity of tyrosine phosphatases and prevents them from catalyzing the hydrolysis of polyphosphate substrates. This inhibition leads to an accumulation of polyphosphates in the bacterial cell membrane, which disrupts its permeability and leads to cell death.

Formule :C16H16O3Degré de pureté :Min. 95%Couleur et forme :PowderMasse moléculaire :256.3 g/mol2-Cyanocinnamic acid
CAS :2-Cyanocinnamic acid is a fatty acid that has been shown to inhibit the synthesis of proteins. It binds to cytochrome c oxidase, inhibiting mitochondrial respiration and electron transport, leading to decreased ATP production. 2-Cyanocinnamic acid is not easily transported out of mitochondria, which leads to its accumulation in the mitochondrial matrix. This accumulation causes synergistic inhibition with glutamate, leading to a decrease in ATP production and an increase in intracellular levels of reactive oxygen species (ROS). The use of 2-cyanoacrylic acid as a mitochondrial transport inhibitor has been proposed for the treatment of obesity and diabetes.
2-Cyanocinnamic acid also inhibits fatty acid uptake by binding to the protein translocase at the outer membrane of cells. This binding prevents monomers from entering the cell, where they are broken down by beta oxidation and converted into acetyl-CoA, which can be used for energy production or stored as triglycerFormule :C10H7NO2Degré de pureté :Min. 95%Masse moléculaire :173.17 g/molN-Acetylethylene Urea-d4

CAS :N-a-t-Boc-N-g-trityl-L-asparagine is a recombinant human protein that has been synthesized in E. coli. It is a peptide with 17β-estradiol at its C terminus, and it binds to the oestrogen receptor α (ERα) via hydrogen bonding interactions. The linker between the asparagine and estradiol is a Boc group that can be removed by protease activity, revealing the active form of 17β-estradiol. ERα ligates to N-a-t-Boc-N-g-trityl L asparagine with high affinity, and this interaction is reversible.
