Abstract: Combination therapies of substituted quinolines and substituted diphenyl sulfones are disclosed. More specifically, compositions containing substituted quinolines and substituted diphenyl sulfones are disclosed. In addition, methods of using the compositions in the treatment of neurodegenerative disorders, including, inter alia, Alzheimer's dementia, HIV-1 associated dementia, and Creutzfeld-Jakob disease are also disclosed.

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.
