V (Tb45) 和 U (Tb46) 和 pretubulysin D (PTb-D43) 等天然微管溶素的改进、简化的全合成,以及它们在合成设计的微管溶素类似物(Tb44、PTb-D42、PTb-D47-PTb)中的应用-D49 和 Tb50-Tb120),进行了描述。合成化合物对某些癌细胞系的细胞毒性评估揭示了许多具有特殊效力的新型类似物[例如,Tb111:IC50 = 40 pM 对 MES SA(子宫肉瘤)细胞系;针对 HEK 293T(人胚胎肾癌)细胞系的 IC50 = 6 pM;和 IC50 = 1.54 nM,对 MES SA DX(具有明显多重耐药性的 MES SA)细胞系]。这些研究产生了一组有价值的构效关系,为进一步的分子设计、合成和生物学评价研究提供指导。

A concise route to the 3-hydroxypyridine core of thiopeptideantibiotics such as nocathiacin is described. Key phases of the sequence involve a modified Hantzsch pyridine construction and a chemoselective Peng deprotection of a phenolic MOM ether.
