Application

2-Chloro-1-(6-methoxy-1,2,3,4-tetrahydroquinolin-1-yl)ethan-1-one is a cysteine-reactive small-molecule fragment for chemoproteomic and ligandability studies for both traditionally druggable proteins as well as "undruggable," or difficult-to-target, proteins. This fragment electrophile, or "scout" fragment, can be used alone in fragment-based covalent ligand discovery or incorporated into bifunctional tools such as electrophilic PROTAC® molecules for targeted protein degradation as demonstrated by the Cravatt Lab for E3 ligase discovery.

Targeted covalent inhibitors have become an integral part of a number of therapeutic protocols and are the subject of intense research. The mechanism of action of these compounds involves the formation of a covalent bond with protein nucleophiles, mostly cysteines.

Nucleophilic attack on carbon-based electrophiles is a central reactivity paradigm in chemistry and biology. The steric and electronic properties of the electrophile dictate its reactivity with different nucleophiles of interest, allowing the opportunity to fine-tune electrophiles for use as coupling

Small molecules are powerful tools for investigating protein function and can serve as leads for new therapeutics. Most human proteins, however, lack small-molecule ligands, and entire protein classes are considered 'undruggable'. Fragment-based ligand discovery can identify small-molecule probes for proteins

Proteomic Ligandability Assessment

Ligandability describes the propensity of a protein target to bind a small molecule with high affinity. It is a precursor to evaluating druggability, which requires more advanced translational pharmacological effects and drug-like properties in vivo.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
