Abstract

Therapeutically useful derivatives are prepared by condensing p-aminobenzenesulphonthiourea with a dibasic carboxylic acid anhydride. In examples: (1) p-aminobenzenesulphonthiourea is condensed with succinic anhydride in the presence of acetone to give p - succinylaminobenzenesulphonthiourea, and (2) p - aminobenzenesulphonthiourea is condensed with phthalic anhydride in the presence of acetone to give p-phthalylaminobenzenesulphonthiourea. The use of maleic anhydride also is referred to. Specification 589,730 is referred to. The Specification as open to inspection under Sect. 91 comprises also the condensation of p-aminobenzenesulphonthiourea with dibasic acids, esters and halides. This subject-matter does not appear in the Specification as accepted.
