  • Discovery of novel hybrids of diaryl-1,2,4-triazoles and caffeic acid as dual inhibitors of cyclooxygenase-2 and 5-lipoxygenase for cancer therapy

    Inflammation plays a key role in cancer initiation and propagation. Cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX), two important enzymes in inflammatory responses are up-regulated in various tumor types. Dual inhibition of COX-2 and 5-LOX constitutes a rational concept for the design of more efficacious anti-tumor agents with an improved safety profile. We have previously reported a series of diaryl-1,2,4-triazole derivatives as selective COX-2 inhibitors. Herein, we hybridized the diaryl-1,2,4triazoles with caffeic acid (CA) which was reported to display 5-LOX inhibitory and anti-tumor activities, affording a novel class of COX-2/5-LOX dual inhibitors as anti-tumor drug candidates. Most of these compounds exhibited potent COX-2/5-LOX inhibitory and antiproliferative activities in vitro. And the most potent compound 22b could significantly inhibit tumor growth in vivo. Furthermore, mechanistic investigation showed that the representative compound 15c blocked cell cycle in G2 phase and induced apoptosis in human non-small cell lung cancer A549 cells in a dose-dependent manner. Our preliminary investigation results would provide new clues for the cancer theatment with COX-2/5-LOX dual inhibitors. (C) 2015 Elsevier Masson SAS. All rights reserved.
  • Structure–activity studies of 4-phenyl-substituted 2′-benzoylpyridine thiosemicarbazones with potent and selective anti-tumour activity

    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.
