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。
