  Minimum structural requirements for cell membrane leakage-mediated anti-MRSA activity of macrocyclic bis(bibenzyl)s

  摘要：

  Macrocyclic bis(bibenzyl)-type phenolic natural products, found exclusively in bryophytes, exhibit potent antibacterial activity towards methicillin-resistant Staphylococcus aureus (anti-MRSA activity). Here, in order to identify the minimum essential structure for cell membrane leakage-mediated anti-MRSA activity of these compounds, we synthesized acyclic fragment structures and evaluated their anti-MRSA activity. The activities of all of the acyclic fragments tested exhibited similar characteristics to those of the macrocycles, i.e., anti-MRSA bactericidal activity, an enhancing effect on influx and efflux of ethidium bromide (EtBr: fluorescent DNA-binder) in Staphylococcus aureus cells, and bactericidal activity towards a Staphylococcus aureus strain resistant to 2-phenoxyphenol (4). The latter result suggests that they have a different mechanism of action from 4, which is a FabI inhibitor previously proposed to be the minimum active fragment of riccardin-type macrocycles. Thus, cyclic structure is not a necessary condition for cell membrane leakage-mediated anti-MRSA activity of macrocyclic bis(bibenzyl)s. (C) 2016 Elsevier Ltd. All rights reserved.

  investigate the alpha-glucosidase-inhibitory activity of typical LXR ligands and the LXR-modulating activity of typical alpha-glucosidase inhibitors. Although there were some exceptions, co-existence of LXR-regulatory and alpha-glucosidase-inhibitory activities seemed to be rather general among the examined compounds. The LXR ligands were found to be non-competitive alpha-glucosidase inhibitors, suggesting that

  最初被报道为氧固醇激活的核受体的肝X受体（LXR）最近被发现将葡萄糖识别为生理配体。在此基础上，我们已经开发了基于源自沙利度胺的α-葡萄糖苷酶抑制剂的新型LXR拮抗剂。在这里，为了阐明α-葡萄糖苷酶抑制与LXR调节之间的关系，我们研究了典型的LXR配体的α-葡萄糖苷酶抑制活性和典型的α-葡萄糖苷酶抑制剂的LXR调节活性。尽管有一些例外，但在所研究的化合物中，LXR调节和α-葡萄糖苷酶抑制活性的共存似乎相当普遍。LXR配体被发现是非竞争性的α-葡萄糖苷酶抑制剂，这表明可能有可能分开这两种活性。为了检验这一想法，我们集中研究了蓖麻毒素C（一种自然存在的LXR配体），在这里我们发现它也是有效的α-葡萄糖苷酶抑制剂。riccardin C的结构发展提供了缺乏α-葡萄糖苷酶抑制活性的新型LXR拮抗剂19c和19f，以及LXRalpha选择性拮抗剂22。
