  Function-Oriented Synthesis of Simplified Caprazamycins: Discovery of Oxazolidine-Containing Uridine Derivatives as Antibacterial Agents against Drug-Resistant Bacteria

  摘要：

  The rational simplification of the caprazamycin (CPZ) class of nucleoside natural products was carried out to address their molecular complexity. First, analogues 6-8, where the diazepanone ring of the CPZ was removed and a lipophilic side chain was attached to either the C-7' or N(6') atom, were used to investigate the conformation activity relationship. On the basis of this relationship, we designed the oxazolidine-containing uridine derivatives 18-21 by restricting the conformation of 6-8. As a result, the 'Bu ester derivatives 20 were found to be the most active against a range of bacterial strains containing VRE with a potency similar to that of the parent CPZs. This study provides a novel strategy for the development of a new type of antibacterial agent effective against drug-resistant bacteria.

  Muraymycin生物合成过程中的自抗性：具有相同修饰位点和不同时间顺序的互补核苷酸转移酶和磷酸转移酶。

  摘要：

  莫来霉素是来自链霉菌属（Streptomyces spp）的抗菌天然产物。抑制涉及细胞壁生物合成的转位酶I（MraY）。在结构上，穆雷霉素由5'-C-甘氨酰尿苷（GlyU）附加在5“-氨基-5”-脱氧核糖（ADR）上形成的二糖核心，该核心存在于MraY的几种肽基核苷抑制剂中。对于穆雷霉素，GlyU-ADR二糖进一步用氨基丙基连接的肽修饰以产生最简单的结构，标注为穆雷霉素D系列。在穆雷霉素生物合成基因簇中编码的两种酶，Mur29和Mur28，在体外功能上分别为Mg·ATP依赖性核苷酸转移酶和Mg·ATP依赖性磷酸转移酶，均修饰了二糖的3″ -OH。生化特征表明，两种酶都可以利用几种核苷酸供体作为共底物，而受体底物穆来霉素也起抑制剂的作用。单底物动力学分析表明，Mur28优先磷酸化合成的GlyU-ADR二糖（一种假定的穆雷霉素的生物合成前体），而Mur29优先腺苷酸化D系列的穆雷霉素。与相应的

  drugs with different mechanisms of action is urgently needed to address antimicrobial resistance. MraY is an essential membrane enzyme required for bacterial cell wall synthesis. Sphaerimicins are naturally occurring macrocyclic nucleoside inhibitors of MraY and are considered a promising target in antibacterial discovery. However, developing sphaerimicins as antibacterials has been challenging due to

  迫切需要开发具有不同作用机制的新型抗菌药物来解决抗菌素耐药性问题。 MraY 是细菌细胞壁合成所需的必需膜酶。 Sphaerimicins 是天然存在的 MraY 大环核苷抑制剂，被认为是抗菌发现中一个有前途的靶点。然而，由于其复杂的大环结构，开发球形霉素作为抗菌药物一直具有挑战性。在这项研究中，我们通过两个关键反应构建了其特征性的大环骨架。然后确定了与 MraY 结合的 sphaerimicin 类似物的结构，我们使用结构引导的方法来设计简化的 sphaerimicin 类似物。这些类似物保留了针对MraY的效力，并对革兰氏阳性菌（包括临床分离的金黄色葡萄球菌和屎肠球菌耐药菌株）表现出有效的抗菌活性。我们的研究结合了合成化学、结构生物学和微生物学，为开发MraY抑制剂作为针对耐药细菌的抗菌药物提供了平台。

  Synthesis of palmitoyl caprazol 7, which possesses a simple fatty acyl side chain at the 3"'-position of the diazepanone moiety, was carried out and their antibacterial activity was evaluated. The key elements of our approach include the improved synthesis of the key 5'-p-0-aminoribosyl-glycyluridine derivative, installation of the palmitoyl side chain to the cyclization precursor, and the construction of the diazepanone by an intramolecular reductive amination. The second generation synthesis of (+)-caprazol was also established. Palmitoyl caprazol 7 exhibited antibacterial activity against Mycobacterium smegmatis ATCC607 (MIC = 6.25 mu g/mL) with potency similar to that of the caprazamycins (CPZs). Palmitoyl caprazol 7 and N-6'-desmethyl palmitoyl caprazol 28 also exhibited antibacterial activity against drug-resistant bacteria including methyciline-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE) strains (MIC = 3.13-12.5 mu g/mL).
