A series of myxopyronin B analogs has been prepared via a convergent synthetic route and were tested for in vitro inhibitory activity against DNA-dependent RNA polymerase and antibacterial activity against E. coli and S. aureus. The parent lead compound proved to be very sensitive to even small changes. Only the achiral desmethyl myxopyronin B (1a) provided enhanced potency. (C) 2004 Elsevier Ltd. All rights reserved.
