title: Pyrrolnitrin analogues. XI--Synthesis and microbiological activity of new 1,4- and 1,5-diarylpyrroles.
abstract: The synthesis and microbiological activities of new 1,4- and 1,5-diarylpyrroles is reported. Antimicrobial data in comparison with fungal antibiotic pyrrolnitrin confirm an interesting antimicotic activity of 1,4-diarylpyrroles. On the contrary 1,5-diarylpyrroles show antibacterial activity and an unexpected antimicotic activity. The position of the 4-nitrophenyl group at C4 or C5 of the pyrrole ring influences antibacterial activity.
