Small molecule covalent inhibitors, or irreversible inhibitors, are a type of inhibitors that exert their biological functions by irreversibly binding to target through covalent bonds. Compared with non-covalent inhibitors, covalent inhibitors have obvious advantages in bioactivity, such that covalent warheads can target rare residues of a particular target protein, thus leading to the development of highly selective inhibitors and achieving a more complete and continued target occupancy in living systems. In recent years, the distinct strengths of covalent inhibitors in overcoming drug resistance had been recognized. However, toxicity can be a real challenge related to this class of therapeutics due to their potential for off-target reactivity and has led to these drugs being disfavored as a drug class. The drug design and optimization of covalent inhibitors has become a hot spot in drug discovery.

MCE covalent inhibitor library contains 3,023 small molecules including identified covalent inhibitors and other molecules having common covalent reactive groups as warheads, such as acrylamides, activated terminal acetylenes, sulfonyl fluorides/esters, cloracetamides, alkyl halides, epoxides, aziridines, disulfides, etc.

MCE Covalent inhibitor Library plus, with more powerful screening capability, further complement Covalent inhibitor Library (HY-L036) by adding some fragment compounds with covalent warheads.

For pre-dissolved solutions, 10 mM for compounds with the solubility not lower than 10 mM, 2 mM for compounds with solubility between 2 mM and 10 mM, and 3 mg/mL for compounds with unconfirmed molecular weight and solubility not lower than 3 mg/mL.

Product Details

Formulation:

A collection of 3,023 molecules supplied as pre-dissolved Solutions or Solid
Solution: 2,987 compounds supplied in 10 mM solution, 24 compounds supplied in 2 mM solution, 3 compounds supplied in 3 mg/mL 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.
