DefinitionChEBI: A sulfone that is diphenylsulfone in which the hydrogen atom at the 4 position of each of the phenyl groups is substituted by an amino group. It is active against a wide range of bacteria, but is mainly employed for its actions against Mycobacteriu leprae, being used as part of multidrug regimens in the treatment of all forms of leprosy.
