Abstract: 1-[4-(4'-sulfanilyl)phenyl]urea and its various substituted derivatives can be used to decrease the infectiousness of and reduce the mortality associated with organisms of the genus Leishmania which are responsible for a group of conditions known as Leishmaniasis. This heretofore unrecognized use extends to the known derivatives of ureidodiaminodiphenyl sulfones and includes the novel aryl-ring hydroxylated series of sulfanilylphenylureas of the formula: ##STR1## wherein m and n can be the same or different and may each =0 or 1, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, and R.sup.6 are the same or different and are selected from the group consisting of hydrogen, hydroxyl, halo, C.sub.1 to C.sub.6 straight or branch chain alkyl, halo alkyl, polyhalo alkyl, alkoxy, cyano, amino, alkanoylamino, alkoxycarbonylamino, carboxy, alkoxycarbonyl, carbamoyl, acyl, R.sup.7, and R.sup.8 are the same or different and are selected from the group consisting of hydrogen, and C.sub.1 to C.sub.
Abstract: There are provided compounds of the formula ##STR1## wherein R.sup.1 is a substituted or unsubstituted divalent aliphatic group of 1 to 16 carbon atoms; wherein the substituents are mono or poly and are selected from the group consisting of lower alkyl, aryl and arlkyl, R.sup.3 is selected from the group consisting of same group of values as R.sup.5, R.sup.5 is selected from the group consisting of substituted and unsubstituted alkyl of 1-10 carbon atoms, aryl, cycloalkyl and heterocycloalkyl of 3-8 carbon atoms, wherein the substituents are mono or poly and are selected from the group consisting of lower alkyl, cycloalkyl of 3-8 carbon atoms, lower alkenyl, lower alkynyl, nitro, lower alkoxy, lower alkoxycarbonyl, phenyl loweralkyl, phenyl, mono and polyhalophenyl, phenoxy, mono and polyhalophenoxy, R.sup.6 and R.sup.7 may be the same or different and are hydrogen, alkanoyl or alkoxyalkanoyl, R.sup.7 may also have the same value as R.sup.
