  Targeting Mycobacterium tuberculosis Biotin Protein Ligase (MtBPL) with Nucleoside-Based Bisubstrate Adenylation Inhibitors

  摘要：

  Mycobacterium tuberculosis (Mtb), responsible for second leading cause of mortality among infectious diseases worldwide. Mycobacterial biotin protein ligase (MtBPL) is an both latent and symptomatic tuberculosis (TB), remains the essential enzyme in Mtb and regulates lipid metabolism through the post-translational biotinylation of acyl coenzyme A carboxylases. We report the synthesis and evaluation of a systematic series of potent nucleoside-based inhibitors of MtBPL that contain modifications to the ribofuranosyl ring of the nucleoside. All compounds were characterized by isothermal titration calorimetry (ITC) and shown to bind potently with K(D)s <= 2 nM. Additionally, we obtained high-resolution cocrystal structures for a majority of the compounds. Despite fairly uniform biochemical potency, the whole-cell Mtb activity varied greatly with minimum inhibitory concentrations (MIC) ranging from 0.78 to >100 mu M. Cellular accumulation studies showed a nearly 10-fold enhancement in accumulation of a C-2'-alpha analogue over the corresponding C-2'-beta analogue, consistent with their differential whole-cell activity.

• Synthesis of 2'-substituted derivatives of neplanocin A (Nucleosides and nucleotides. XLIV).
  作者：KIYOFUMI FUKUKAWA、TOHRU UEDAO、TAKAO HIRANO

  DOI：10.1248/cpb.31.1582

  日期：——

  Neplanocin A (1) and N6-benzoylneplanocin A (2) were converted to the corresponding 3', 6'-O-(tetraisopropyldisiloxane-1, 3-diyl)-neplanocin A's (3, 4). The 2'-hydroxy group in 3 and 4 was triflated (5, 6). Nucleophilic displacement of 5 and 6 with a number of nucleophiles (I-, Br-, Cl-, N3-, AcO-, AcS-) in hexamethylphosphoric triamide afforded the corresponding 2' (R)-substituted derivatives in high yields. The 2' (S)-azido derivatives were obtained in a similar manner from arabinoneplanocin A prepared by this method. Adenosine was also converted to 2' (R)-substituted derivatives, including arabinofuranosyladenine, as well as 2' (S)-substituted adenosines. The physical properties of these 2'-substituted derivatives of neplanocin A and adenosine, including nuclear magnetic resonance and circular dichroism spectra, are presented.

  Neplanocin A（1）和 N6-苯甲酰基eplanocin A（2）被转化为相应的 3'，6'-O-（四异丙基二硅氧烷-1，3-二基）-eplanocin A（3，4）。3 和 4 中的 2'-羟基被三氟化（5，6）。在六甲基磷酸三酰胺中，用多种亲核剂（I-、Br-、Cl-、N3-、AcO-、AcS-）对 5 和 6 进行亲核置换，可以高产率得到相应的 2' (R)-取代衍生物。用这种方法制备的阿糖胞苷 A 也以类似的方式得到了 2' (S)-叠氮衍生物。腺苷也被转化为 2' (R)-取代的衍生物，包括阿拉伯呋喃糖基腺嘌呤，以及 2' (S)-取代的腺苷。文中介绍了这些 2'-取代的肾上腺素 A 和腺苷衍生物的物理性质，包括核磁共振和圆二色光谱。
