Cysteine Covalent Library
The theoretical basis of FBDD is to select favorable fragment combinations or extensions to obtain new drug molecules, with a higher probability of obtaining highly active drug candidates. Compared with the screening of millions of macromolecules, thousands of fragment molecules can be combined to form millions of drug structures, which are easier to collect and manage. In addition, fragments have smaller molecular weights, relatively higher solubility, and easier structural optimization. The potential of over-the-counter medicine is higher. In recent years, covalent chemical probes have become an important tool for drug discovery. A large number of successful applications in the evaluation of protein druggability, especially the successful application of Cys residues, bring hope for the discovery and synthesis of new covalently modified compounds. To this end, we designed a cysteine-specific covalent library. The electrophilic "warhead" of the fragments is acrylamide or chloroacetamide (25% and 75% of the library, respectively). These functional groups were chosen to construct the library because they are in the "best position" for reactivity and show selectivity in chemical proteomics screening. Uses: Scientific use.

Cysteine, S-Nitrosylated (SNO-Cys) (BSA)
Nitric oxide (NO), generated by cell type-specific NO- synthase (NOS) isoforms, is a freely diffusible intercellular messenger that functions in target cells in NOS-dependent signaling. S-nitrosylation of cysteine thiols in proteins by the highly labile NO radical has been identified as an important effector of NO-related bioactivity both in NOS- containing cells and intercellular signaling. Most cells contain low levels of nitrosylated proteins that are thought to be regulated by S-nitrosylation and denitrosylation. S-nitrosylation of proteins serves as a ubiquitous post- translational modification that dynamically regulates a broad functional spectrum of proteins. The majority of these proteins are regulated by S-nitrosylation on a single critical cysteine residue within an acidic/basic or hydrophobic structural motif that may also be subject to oxygen- or glutathione-dependent modification.
