Organic iodides are organic compounds containing a carbon-iodine (C-I) bond. 144-48-9, formula is C2H4INO, Name is 2-Iodoacetamide.The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Application In Synthesis of 144-48-9.
Zsido, Balazs Zoltan;Borzsei, Rita;Pinter, Erika;Hetenyi, Csaba research published 《 Prerequisite Binding Modes Determine the Dynamics of Action of Covalent Agonists of Ion Channel TRPA1》, the research content is summarized as follows. Transient receptor potential ankyrin 1 (TRPA1) is a transmembrane protein channeling the influx of calcium ions. As a polymodal nocisensor, TRPA1 can be activated by thermal, mech. stimuli and a wide range of chem. damaging mols. including small volatile environmental toxicants and endogenous algogenic lipids. After activation by such compounds, the ion channel opens up, its central pore widens allowing calcium influx into the cytosol inducing signal transduction pathways. Afterwards, the calcium influx desensitizes irritant evoked responses and results in an inactive state of the ion channel. Recent exptl. determination of structures of apo and holo forms of TRPA1 opened the way towards the design of new agonists, which can activate the ion channel. The present study is aimed at the elucidation of binding dynamics of agonists using exptl. structures of TRPA1-agonist complexes at the at. level applying mol. docking and dynamics methods accounting for covalent and non-covalent interactions. Following a test of docking methods focused on the final, holo structures, prerequisite binding modes were detected involving the apo forms. It was shown how reversible interactions with prerequisite binding sites contribute to structural changes of TRPA1 leading to covalent bonding of agonists. The proposed dynamics of action allowed a mechanism-based forecast of new, druggable binding sites of potent agonists.
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.
