Description: Covalent inhibitors are small molecules that can bind specifically to target proteins through covalent bonds and inhibit their biological functions. Although for a long time, covalent targeting has been playing a subordinate role in drug discovery, with an increasing number of reports on successful clinical applications of such drugs, the potential of these agents is now being acknowledged. Currently, cysteine is the most common covalent amino acid residue in a variety of covalent drugs, and various warheads have been developed that can react with cysteine, providing the key building blocks for covalent drugs to form covalent bonds.

Currently, cysteine is the most common covalent amino acid residue in a variety of covalent drugs, and various warheads have been developed that can react with cysteine, providing the key building blocks for covalent drugs to form covalent bonds.
To meet the development needs of covalent inhibitors targeting cysteine, MCE has designed a unique collection of 4522 compounds with different covalent warheads that target cysteine. The MCE Cysteine Targeted Covalent Library is designed using the following covalent warheads: Acrylamides, Propiolic acid ester, Dimethylamine functionalized acrylamides, Chloroacetamides, Acrylonitrile, 2-Cyanoacrylamide, Aziridine, Haloacetamide, etc.
MCE Cysteine Targeted Covalent Library can be supplied as pre-dissolved Solutions or Solid. For pre-dissolved solutions in this library, there are 4497 compounds supplied in 10 mM solution and 5 compounds supplied in 2 mM solution.
For pre-dissolved solutions, 10 mM for compounds with the solubility not lower than 10 mM, and 2 mM for compounds with solubility between 2 mM and 10 mM.

Formulation: A collection of 4522 compounds with different covalent warheads that target cysteine supplied as pre-dissolved Solutions or Solid.Solution:4497 compounds supplied in 10 mM solution,5 compounds supplied in 2 mM solution.
Layout: 96-well storage tube or 96-well plate: 1st and 12th column are left empty.384-well plate: the first two columns and the last two columns are left empty.Compounds with different concentrations or dissolved in different solvents will be put on separate plates.This way of layout may increase the number of plates because there could be three solvents and three concentrations. If you have other requirements, please let us know.
Container: 96- or 384-well Plate with Peelable Foil Seal; 96-well Format Sample Storage Tube With Screw Cap and Optional 2D Barcode.
