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.
