NON-MERCURIAL DIURETICS

摘要

Novel, nontoxic, nonmercurial diuretic compounds are disclosed, which are potassium derivatives of 2-phenyl-6-sulphamyl-7-chloro-1,2,3,4-tetrahydro-4-quinazolinone. The monopotassium derivative is obtained by replacing either hydrogen of the sulphamyl group of the starting quinazolinone by a potassium atom, whereas the dipotassium derivative is obtained by replacing either hydrogen of the sulphamyl group of the starting quinazolinone and also the hydrogen atom lying in the 3-position of the tetrahydro-quinazolinone ring of same starting quinazolinone by a potassium atom each.
