  2⁢'-苯甲酰吡啶缩氨基硫脲（BpT）是一种有效的铁螯合剂，并显示出对肿瘤细胞具有强大的抗增殖活性。为了更深入地了解BpT螯合剂的构效关系，合成了10种新的含有N4-苯基取代基的BpT类似物。重要的是，先前未曾探索过在BpT骨架的该位置进行芳香族取代，这些研究代表了首次尝试调查其构效关系。这些化合物相对于临床使用的铁螯合剂去铁胺（DFO）显示了显著增强的抗增殖活性。此外，这些化合物在体外对癌细胞相对于正常细胞显示出可观的疗效指数。构效关系分析表明，供电子取代基如-CH3和-OCH3导致的抗增殖活性大于吸电子基团如-Br和-Cl。这些发现有助于阐明各种4-苯基取代基对BpT系列螯合剂生物活性的影响，并有助于未来开发具有改善抗肿瘤活性的缩氨基硫脲。

  2′-Benzoylpyridine thiosemicarbazones (BpT) are effective iron chelators and display potent anti-proliferative activity against tumour cells. In order to gain greater insight into the structure–activity relationships of the BpT chelators, ten new analogues containing phenyl substituents at the N4-position of the BpT structure were synthesised. Importantly, aromatic substitution at the latter position of the BpT scaffold has not been previously explored and these studies represent the first attempt to investigate their structure–activity relationships. These compounds demonstrated significantly enhanced anti-proliferative activity compared to the clinically used iron chelator, desferrioxamine (DFO). Furthermore, the compounds showed appreciable therapeutic indices against cancer cells over normal cells in vitro. Structure–activity analysis revealed that electron-donating substituents such as –CH3 and –OCH3 resulted in greater anti-proliferative activity than electron-withdrawing groups such as –Br and –Cl. These findings help to elucidate the effect of a variety of 4-phenyl substituents on the biological activity of BpT series of chelators and facilitate the future development of thiosemicarbazones with improved anti-tumour activity.
