Description: 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 Lead-like Covalent Screening Library offers a valuable resource of 500 lead-like compounds with commonly used covalent warheads. These warheads, such as acrylamide, activated terminal alkyne, acyloxymethyl ketone, and boronic acid, are capable of reacting with specific amino acid residues, including cysteine, lysine, serine, and histidine. The inclusion of these reactive warheads in the library allows researchers to explore the potential of covalent inhibition, a powerful approach in drug discovery.
Advantages:
- A unique collection of 500 compounds that show covalent binding with target proteins for high throughput screening (HTS) and high content screening (HCS).
- Careful choice of warheads: only experimentally confirmed reactivity, no over-reactive warheads, no alternative reactive functionalities.
- Chemical probes that show enhanced selectivity, potency and utility for biological studies.
- Compatible with “Lipinski’s Rule of Five”, with multiple characteristics such as calculated good solubility (-3.2 < logP < 5), oral bioavailability (RotB <= 10), drug transportability (PSA < 120), MW between 300 to 500, number of Hydrogen Bond Donor (HBD)≤5, number of Hydrogen Bond Acceptor (HBA)≤10.
- All compounds are available off the shelf.
- LCMS or NMR validated to ensure high purity and quality.
Formulation: This library contains 500 lead-like compounds with commonly covalent warheads, such as acrylamide, activated terminal alkyne, acyloxymethyl ketone, and boronic acid.
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.
