Many currently available antifungal and antibacterial agents have undesirable toxic effects, and a wide spread use of these drugs has lead to rapid development of drug resistant strains which are the leading cause for treatment failure in both clinical and agricultural applications. The present article provides a synopsis of recent progress in investigations of new classes of antifungal compounds: disubstituted aliphatic and aromatic thioureas, triazole and thiazine compounds which act as ligands for transition metals. Antifungal effects of these compounds and selected metallic complexes versus representative plant pathogenic fungi are reviewed.
