[A substance with antibacterial and antifungal activity. V. Synthesis and microbiological activity of new derivatives of 1,5-diarylpyrrole].

The synthesis and antifungal activities of new 1,5-diarylpyrrole derivatives are reported. The N-methylpiperazinyl substituent must be regarded as fundamental to activity. Furthermore the presence of substituents on the para position of the two phenyl rings and the presence of halogen atoms can be considered strengthening factors to microbiological activity. The results obtained are discussed on the basis of structure-activity relationship.
