CAS 5790-69-2: 2-Amino-5-chlorobenzenesulfonamide

2-Amino-5-chlorobenzenesulphonamide

2-Amino-5-chlorobenzenesulfonamide is a synthetic chemical that is used in the manufacture of amides and diazoxide. It is also found naturally in humans as a metabolite of the amino acid histidine. 2-Amino-5-chlorobenzenesulfonamide has been shown to be a potent receptor for the modulation of acetylcholine release by binding to muscarinic receptors, including M1 and M2 subtypes, and inhibiting the enzyme hydrolysis of acetylcholine. This chemical has been shown to be chemically stable at pH 5 or higher, and it has been found to be resistant to hydrolysis by enzymes such as esterases, glucuronidases, glutathione reductase, and cytochrome P450. 2-Amino-5-chlorobenzenesulfonamide is also an enantiomer that can bind to collagen in the human

Applications 2-Amino-5-chlorobenzenesulfonamide is a metabolite of IDRA-21 (I232500), which inhibits AMPA receptor desensitization and enhances cognition by a related mechanism. IDRA-21 is more able to cross the blood-brain barrier than Cyclothiazide (C988960). References Cannazza, G., et. al.: Bioorg. Med. Chem. Lett., 19, 1254 (2009); Zivkovic, et al.: J. Pharmacol. Exp.
