[Antifungal properties of N-aryl-substituted maleaminic acids, their imides and copper salts].

The influence of 39 compounds (N-aryl-maleiminic acids, N-aryl-maleinimid and Cu-N-arylmaleiminic acids) on the growth of Aspergillus niger, A. terreus and Penicillium cyclopium has been studied. Maleimides have been shown to have the more toxic effect on the fungi.
