Synthesis and biological properties of derivatives of 3-methyl-5-aminoisothiazolo-4-carboxylic acid. 1976

Z Machón

The reaction of 3-methyl-5-aminoisothiazolo-4-carboxylic acid with the chlorides of chloroacetaic acid and chloropropionic acid gave 3-methyl-5-chloroacetyl- and 5-chloropropionylisothiazolo-4-carboxylic acids, which upon heating in anhydrous ethanol with aliphatic and aromatic amines gave the respective 5-aminoacetyl and amino-propionyl derivatives of these acids. Iodoacetyloaminoisothiazolo-4-carboxylic acid in reaction with ammonia was converted in 3-methylo-5-aminoacetylo-aminoisothiazolo-4-carboxylic acid, which upon heating in toluene with isocyanates and isothiocyanates gave the respective derivatives of urea and thiourea. Some of the synthesized compounds showed psychotropic and cytostatic activity.
