  Synthesis of hydroxypyrone- and hydroxythiopyrone-based matrix metalloproteinase inhibitors: Developing a structure–activity relationship

  摘要：

  The zinc(II)-dependent matrix metalloproteinases (MMPs) are associated with a variety of diseases. Development of inhibitors to modulate MMP activity has been an active area of investigation for therapeutic development. Hydroxypyrones and hydroxythiopyrones are alternative zinc-binding groups (ZBGs) that, when combined with peptidomimetic backbones, comprise a novel class of MMP inhibitors (MMPi). In this report, a series of hydroxypyrone- and hydroxythiopyrone-based MMPi with aryl backbones at the 2-, 5-, and 6- positions of the hydroxypyrone ring have been synthesized. Synthetic routes for developing inhibitors with substituents at two of these positions (so-called double-handed inhibitors) are also explored. The MMP inhibition profiles and structure-activity relationship of synthesized hydroxypyrones and hydroxythiopyrones have been analyzed. The results here show that the ZBG, the position of the backbone on the ZBG, and the nature of the linker between the ZBG and backbone are critical for MMPi activities. (C) 2009 Elsevier Ltd.

  基于片段的流感核酸内切酶抑制剂的鉴定

  摘要：

  流感病毒每年造成数百万例严重疾病。疫苗效力的逐年变化，加上新出现的耐药性，有必要开发用于治疗流感感染的新药。一种有吸引力的靶标是RNA依赖性RNA聚合酶PA亚基。本文中，我们报道了从金属结合药效团（MBP）库筛选中鉴定出的先导化合物衍生的流感PA核酸内切酶抑制剂的发展。发现焦果烯酸及其衍生物是核酸内切酶的有效抑制剂。在建模和先前报道的结构数据的指导下，从MBP命中中精心制作了分子的几个子库。建立了结构与活动的关系，使用片段增长和片段合并策略设计和合成了更有效的分子。这种方法最终导致了带有IC的铅化合物的开发50值为14 nM，显示MDCK细胞中针对H1N1流感病毒的EC 50值为2.1μM。

  The influenza virus is responsible for millions of cases of severe illness annually. Yearly variance in the effectiveness of vaccination, coupled with emerging drug resistance, necessitates the development of new drugs to treat influenza infections. One attractive target is the RNA-dependent RNA polymerase PA subunit. Herein we report the development of inhibitors of influenza PA endonuclease derived
