  New Antibacterial Agents Derived from the DNA Gyrase Inhibitor Cyclothialidine

  摘要：

  Cyclothialidine (1, Ro 09-1437) is a potent DNA gyrase inhibitor that was isolated from Streptomyces filipinensis NR0484 and is a member of a new family of natural products. It acts by competitively inhibiting the ATPase activity exerted by the B subunit of DNA gyrase but barely exhibits any growth inhibitory activity against intact bacterial cells, presumably due to insufficient permeation of the cytoplasmic membrane. To explore the antibacterial potential of 1, we developed a flexible synthetic route allowing for the systematic modification of its structure. From a first set of analogues, structure-activity relationships (SAR) were established for different substitution patterns, and the 14-hydroxylated, bicyclic core (X) of 1 seemed to be the structural prerequisite for DNA gyrase inhibitory activity. The variation of the lactone ring size, however, revealed that activity can be found among 11- to 16-membered lactones, and even seco-analogues were shown to maintain some enzyme inhibitory properties, thereby reducing the minimal structural requirements to a rather simple, hydroxylated benzyl sulfide (XI). On the basis of these "minimal structures" a modification program afforded a number of inhibitors that showed in vitro activity against Gram-positive bacteria. The best activities were displayed by 14-membered lactones, and representatives of this subclass exhibit excellent and broad in vitro antibacterial activity against Gram-positive pathogens, including Staphylococcus aureus, Streptococcus pyogenes, and Enterococcus faecalis, and overcome resistance against clinically used drugs. By improving the pharmacokinetic properties of the most active compounds (94, 97), in particular by lowering their lipophilic properties, we were able to identify congeners of cyclothialidine (1) that showed efficacy in vivo.

  prepared containing rhenium, as a surrogate metal for technetium-99m, with a cyclopentadienylrhenium tricarbonyl being situated at the terminus of the residue-3 side chain, yielding compounds the best of which had a 35 nM IC50. This represents a rare case of incorporating rhenium into a peptide structure where the metal complex is required for biological activity. These fluorine and rhenium derivatives demonstrate

  在努力创建针对生长激素促分泌素受体（GHSR）的成像探针的过程中，我们现在报告了通过修饰正辛酰基Ser-3侧链设计和合成含氟和rh的生长素释放肽类似物的过程。使用二氨基丙酸（Dpr）作为残基-3，设计了氟类似物，使氟原子位于脂族链的末端。制备了截短的ghrelin（1-5）和ghrelin（1-14）含氟类似物，其中最好的类似物具有用于GHSR的28 nM IC 50。还制备了Ghrelin（1-14）类似物，其中含有rh，作为m 99m的替代金属，三羰基环戊二烯基r位于残基3侧链的末端，产生的化合物中最好的是35 nM IC50。这代表了将rh掺入肽结构的罕见情况，其中金属配合物是生物活性所必需的。这些氟和rh衍生物表现出修饰ghrelin的Ser-3侧链的能力，以便为GHSR创建成像探针。
