    Myxopyronin B analogs as inhibitors of RNA polymerase, synthesis and biological evaluation
    摘要:
    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.

  • The Total Synthesis of Corallopyronin A and Myxopyronin B
    作者:Andreas Rentsch、Markus Kalesse
    DOI:10.1002/anie.201206560
    日期:2012.11.5
    Leading the way: The synthesis of natural products with new biological targets is one of the driving forces for the development of new antibiotics. The synthesis of the two secondary metabolites corallopyronin and myxopyronin (see picture) have been achieved, which are prominent leads for the inhibition of bacterial RNA polymerase.
    引领潮流:合成具有新生物靶标的天然产物是开发新抗生素的驱动力之一。已经实现了两种次生代谢产物珊瑚红素和粘氧嘧啶的合成(见图),这是抑制细菌RNA聚合酶的重要线索。
