Covalent Fragment Libraries

Recent years witnessed significant growth in the number of drug candidates with covalent mechanism of action progressing through clinical trials or being approved; moreover, about 30% of the marketed drugs are covalent binders. Following this trend, we have designed series of Covalent Fragment Libraries by combining the reactive electrophilic/nucleophilic moieties capable of covalent bond formation and lead-like cores. Careful choice of “warheads” provided the right balance between reactivity and selectivity to be most convenient for wide range of bioassays.

Specially synthesized sets for covalent FBDD projects classified by “warheads”:
