  Synthesis and Antimycobacterial Activity of 2,1′-Dihydropyridomycins

  摘要：

  Dihydropyridomycins 2 and 3, which lack the characteristic enol ester moiety of the potent antimycobacterial natural product pyridomycin (1), have been prepared from L-Thr, R- and S-hydroxy isovaleric acid, and 3-pyridinecarboxaldehyde. The 2R isomer 2 shows only 4-fold lower anti-Mtb activity than 1, indicating that the enol ester moiety in the natural product is not critical for its biological activity. This finding establishes 2 as a potent and more practical lead for anti-TB drug discovery.

  A series of derivatives of the antimycobacterial natural product pyridomycin have been prepared with the C2 side chain attached to the macrocyclic core structure by a C-C single bond, in place of the synthetically more demanding enol ester double bond found in the natural product. Hydrophobic C2 substituents of sufficient size generally provide for potent anti-Mtb activity of these dihydropyridomycins

  已经制备了一系列抗分枝杆菌天然产物吡咯霉素的衍生物，其中C2侧链通过CC单键连接到大环核心结构上，代替了天然产物中合成上要求更高的烯醇酯双键。足够大小的疏水性C2取代基通常为这些二氢吡啶霉素提供强大的抗Mtb活性（最小抑制浓度（MIC）约为2.5μM），因此一些类似物接近天然吡咯霉素的活性。令人惊奇地，与吡啶霉素相反，这些化合物中的一些对结核分枝杆菌（Mtb）中InhA的过表达不敏感。
