In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate. 144-48-9, formula is C2H4INO, Name is 2-Iodoacetamide. Worldwide, iodine deficiency affects two billion people and is the leading preventable cause of intellectual disability. Application In Synthesis of 144-48-9.
Diemer, Vincent;Ollivier, Nathalie;Leclercq, Berenice;Drobecq, Herve;Vicogne, Jerome;Agouridas, Vangelis;Melnyk, Oleg research published 《 A cysteine selenosulfide redox switch for protein chemical synthesis》, the research content is summarized as follows. The control of cysteine reactivity is of paramount importance for the synthesis of proteins using the native chem. ligation (NCL) reaction. We report that this goal can be achieved in a traceless manner during ligation by appending a simple N-selenoethyl group to cysteine. While in synthetic organic chem. the cleavage of carbon-nitrogen bonds is notoriously difficult, we describe that N-selenoethyl cysteine (SetCys) loses its selenoethyl arm in water under mild conditions upon reduction of its selenosulfide bond. Detailed mechanistic investigations show that the cleavage of the selenoethyl arm proceeds through an anionic mechanism with assistance of the cysteine thiol group. The implementation of the SetCys unit in a process enabling the modular and straightforward assembly of linear or backbone cyclized polypeptides is illustrated by the synthesis of biol. active cyclic hepatocyte growth factor variants.
Application In Synthesis of 144-48-9, 2-Iodoacetamide is a synthetic retinoid that binds to the DNA of cells, altering transcription. It also has been found to be effective in treating bowel disease and has been shown to have dna binding activity. The compound was synthesized by attaching iodine molecules to acetamide. 2-Iodoacetamide targets the protein thiols on the surface of cells, which are responsible for oxidation and damage due to reactive oxygen species (ROS). This compound is metabolized by alcohol dehydrogenase and can be used as a biological sample or natural compound is a compound used as an electrophile for covalent modification of nucleophilic residues on proteins (cysteine, methionine, histidine). When modifying the active-site residues of cysteine proteases, α-Iodoacetamide acts as an irreversible inhibitor of these enzymes.
2-Iodoacetamide used in peptide mapping because it covalently binds with thiols in cysteine residues, thereby preventing disulfide bond formation. By virtue of reaction with cysteine, it is an irreversible inhibitor of enzymes with cysteine at the active site. Also reacts with histidine residues though much more slowly, and this activity is responsible for inhibition of ribonuclease.
An alkylating sulfhydryl reagent. Its actions are similar to those of iodoacetate., 144-48-9.
