  Small molecules with structural similarities to siderophores as novel antimicrobials against Mycobacterium tuberculosis and Yersinia pestis

  摘要：

  Drugs inhibiting the iron scarcity-induced, siderophore-mediated iron-scavenging systems of Mycobacterium tuberculosis (Mtb) and Yersinia pestis (Yp) may provide new therapeutic lines of defense. Compounds with structural similarities to siderophores were synthesized and evaluated as antimicrobials against Mtb and Yp under iron-limiting conditions, which mimic the iron scarcity these pathogens encounter and must adapt to in the host, and under standard iron-rich conditions for comparison. New antimicrobials were identified, some of which warrant exploration as initial leads against potentially novel targets and small-molecule tools to assist in the elucidation of targets specific to iron-scarcity adapted Mtb and Yp.

• Diarylalkanes as potent inhibitors of binuclear enzymes
  申请人：Jia Qi

  公开号：US20050267047A1

  公开（公告）日：2005-12-01

  The present invention implements a strategy that combines an enzyme inhibition assay with a chemical dereplication process to identify active plant extracts and the particular compounds—diarylalkanes and/or diarylalkanols within those extracts that specifically inhibit binuclear enzyme function. Included in the present invention are compositions of matter comprised of one or more of diarylalkanes and/or diarylalkanols, which inhibit the activity of binuclear enzymes, particularly tyrosinase and which prevent melanin overproduction. The present invention also provides a method for inhibiting the activity of a binuclear enzyme, particularly tyrosinase and a method for preventing and treating diseases and conditions related to binuclear enzyme function. The present invention further includes a method for preventing and treating melanin overproduction and diseases and conditions of the skin related thereto. The method for preventing and treating diseases and conditions related to binuclear enzyme function and melanin overproduction is comprised of administering to a host in need thereof an effective amount of a composition comprising one or more diarylalkanes and/or diarylalkanols synthesized and/or isolated from one or more plants together with a pharmaceutically acceptable carrier.
