Library of Cys-specific covalent electrophilic binders
3 200 compounds
Covalent chemical probes become an important tool in drug discovery within last few years. The impressive number of successful applications in protein drugability assessment, especially focusing on Cys residue, brought aspiration to discovery and synthesis of new covalent modifiers.
We used deep knowledge-based approach to design and synthesize our cysteine focused fragment library. Careful choice of covalent warheads based on their reactivity was performed by experienced chemists and reflected a small set of specific structural filters. Electrophilic fragments selected by structural filters were then analyzed to remove any molecules with trivial or unwanted structural features. The resulting set was refined with Ro3 criteria applied to “core structures” to yield 3 200 fragments able to form covalent bonds with cysteine residues.
Hits derived from this library can be easily followed with analogues from stock or either synthesis of new compounds through REAL Database technology.
