triazole-containing chemical series was shown to inhibit tubulin polymerization and cause cell cycle arrest in A431 cancer cells with EC(50) values in the single digit nanomolar range. Binding experiments demonstrated that representative active compounds of this class compete with colchicine for its binding site on tubulin. The syntheses and structure-activityrelationship studies for the triazole derivatives

rocaglate (flavagline) naturalproduct, aglaroxin C displays intriguing biological activity by inhibiting hepatitis C viral entry. To further elucidate structure-activity relationships and diversify the pyrimidinone scaffold, we report a concise synthesis of aglaroxin C utilizing a highly regioselective pyrimidinone condensation. We have prepared more than 40 aglaroxin C analogues utilizing various amidine
作为一种独特的 rocaglate (flavagline) 天然产物,aglaroxin C 通过抑制丙型肝炎病毒进入显示出有趣的生物活性。为了进一步阐明构效关系并使嘧啶酮支架多样化,我们报告了利用高度区域选择性嘧啶酮缩合的 aglaroxin C 的简明合成。我们已经利用各种脒缩合伙伴制备了 40 多种 aglaroxin C 类似物。通过对类似物的生物学评估,我们发现了两种先导化合物 CMLD012043 和 CMLD012044,它们显示出对丙型肝炎病毒进入抑制与翻译抑制的优先偏向。总体而言,该研究证明了化学合成能够产生具有靶向抑制偏向性和改善的治疗指数的天然产物变体。
Pot, atom and step economic synthesis: a diversity-oriented approach to construct 2-substituted pyrrolo[2,1-f][1,2,4]triazin-4(3H)-ones

A diversity-oriented approach to construct 2-heteroaryl-substituted pyrrolo[2,1-f][1,2,4]triazin-4(3H)-one derivatives via copper-promoted two-step one pot reactions from chromenone derivatives has been developed. Pot, atom and step economy (PASE) were combined in these sequential reactions, and at least six bonds were formed in one pot. A number of drug-like small molecules were prepared quickly and efficiently.
