The first total synthesis for large-scale production and anticancer activity of novel aminophenylpyridinium-5-(hydroxybenzoyl)hydrazonomethyl-2-oxothiazol-3-ide (PBHT) (1) and its derivatives are reported. The chemical structure of PBHT was unambiguously determined by utilization of the two-dimensional nuclear Overhauser effect (NOE) technique. The anticancer activity against human colon adenocarcinoma (HCT15) cells of all synthesized compounds was approximately four-fold greater than that of 5-fluorouracil, with IC50 values ranging from 10.1 to 14.2 µM. The three structural determinants of hydroxybenzoyl, hydrazinylidene, and pyridinium oxothiazole in the synthesized compounds could be indispensable for exhibiting anticancer activity.
本研究首次报道了新型氨基苯基吡啶鎓-5-(羟基苯甲酰基)肼甲基-2-氧代噻唑-3-ide (PBHT)(1)及其衍生物的全合成大规模生产和抗癌活性。通过利用二维核欧豪瑟效应(NOE)技术,明确确定了 PBHT 的化学结构。所有合成化合物对人结肠腺癌(HCT15)细胞的抗癌活性约为 5-氟尿嘧啶的四倍,IC50 值为 10.1 至 14.2 µM。合成化合物中的羟基苯甲酰基、亚肼基和吡啶氧噻唑这三种结构决定因素可能是发挥抗癌活性不可或缺的因素。
