not following this labeling strategy. Adopting the principle of replacing phenyl rings by [Re(CO)3(Cp)] entities, potent histone deacetylase (HDAC)‐inhibiting Re analogs of suberoylanlilide hydroxamic acid (SAHA; N‐hydroxy‐N′‐phenyloctanediamide) were synthesized and characterized. Cytotoxic evaluation on different tumor cell lines revealed low IC50 values [μM] for these compounds, comparable to their
从不对称蒂勒酸衍生物开始,两种不同的成像探针 [99mTc(CO)3(CpR)](R=潜在靶向载体)在一锅中从一种底物同时产生。这扩展了先前引入的金属介导的 Retro-DielsAlder 与 HCp-R 二聚体反应的标记策略。我们证明化学活性官能团如异羟肟酸不遵循这种标记策略。采用[Re(CO)3(Cp)]实体取代苯环的原理,合成并表征了强效的组蛋白脱乙酰酶(HDAC)抑制性辛二酰苯胺异羟肟酸(SAHA;N-羟基-N'-苯基辛二酰胺)的Re类似物. 对不同肿瘤细胞系的细胞毒性评估显示,这些化合物的 IC50 值较低 [μM],与其纯有机同源物相当。
