streamlined total syntheses of natural tubulysins such as V (Tb45) and U (Tb46) and pretubulysin D (PTb-D43), and their application to the synthesis of designedtubulysinanalogues (Tb44, PTb-D42, PTb-D47-PTb-D49, and Tb50-Tb120), are described. Cytotoxicity evaluation of the synthesized compounds against certain cancer cell lines revealed a number of novel analogues with exceptional potencies [e.g., Tb111:
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 MESSA(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 MESSA DX(具有明显多重耐药性的 MESSA)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。
