of pathogenic bacteria with MICs as low as 3.1 μM. A structureactivityrelationshipstudy identified the key structural components necessary for inhibition of both bacterial growth and transcription. Correlation of in vitro transcription inhibition activity with in vivo mechanism of action was established using fluorescence microscopy and resistance passaging using Gram-positive bacteria showed no

Some 2-(7-indolyl)pyrroles have been synthesised from the 4,6-dimethoxyindoles 4, 19 and 20 using the modified Vilsmeier reaction. The indolylpyrrole 8 was formed by dehydrogenation of the 2-(7-indolyl)pyrroline 7, which was obtained from indole 4, methyl pyrrolidin-2-one-5-carboxylate and bromopyrrolidin-2-one 11 and phosphoryl chloride to give the 3-chloro-2-(7-indolyl)pyrrolines 12, 29 and 30, which undergo subsequent dehydrohalogenation to give the indolylpyrroles 13, 33 and 34.

mechanism of antibacterialactivity. Several classes of structurally related bis-indole inhibitors of bacterial transcription initiation complex formation were synthesized and their antimicrobialactivities were evaluated. Condensation of indole-7- and indole-2-carbohydrazides with 7- and 2-trichloroacetylindoles or indole-7- and indole-2-glyoxyloyl chlorides resulted in the successful synthesis of 7,7′-
