    摘要: The present invention relates to a series of new compounds, their salts and esters and to methods for the preparation of the compounds having the general formula:

    IN WHICH R1 represents a straight or branched C1-C6 alkyl, alkenyl or alkynyl radical, or a C1-C3 alkyl radical substituted with phenyl, halophenyl, trifluoromethylphenyl, (lower alkoxy)phenyl, or with a 5-membered or 6-membered heterocyclic ring containing not more than two heteroatoms selected from the group consisting of oxygen, sulphur and nitrogen; R2 stands for a phenyl radical, optionally being substituted with halogen, lower alkyl, hydroxy, or lower alkoxy; X stands for oxygen, sulphur or C O; Y stands for oxygen, sulphur or a methylene radical. The compounds of the invention which are valuable in the human and veterinary practice, possess an outstanding diuretic and saluretic activity.

    摘要: A process of in situ forming a dye discharge reagent on at least a portion of surface of a dyed substrate, effected by applying two or more compositions comprising reactants on the substrate, such that the reactants undergo a chemical reaction on the substrate to form the reagent is provided herein, as well as a method for dye discharging a dyed substrate using the process of in situ forming a dye discharge reagent, and a dye discharge composition comprising said dye discharge reagent. In some embodiments of the invention, the reactants are thiourea and a peroxide, and the dye discharge reagent is formamidine sulfinic acid (FSA).
