Synthesis and antibacterial activity of 1-(arylamino)-1H-pyrroles and 4-(1H-pyrrol-1-ylimino)-2,5-cyclohexadienes.

: The syntheses of 1-(arylamino)-1H-pyrroles and 4-(1H-pyrrol-1-ylimino)-2-5-cyclohexadienes are described. Several of these compounds express in vitro antibacterial activity or can be metabolized to show in vitro antibacterial activity, and a few examples have shown efficacy against tuberculosis in mice. One compound, N,N'-(2,5-cyclohexadiene-1,4-diylidene)bis-1H-pyrrol-1-amine, is completely effective at 6.25 mg/kg against Mycobacterium tuberculosis H37Rv.
