‘Click’ derived 1, 2, 3-triazolium salts as potential anticancer drugs
Modern synthetic chemistry is powered by new synthetic protocols that allow the rapid generation of compound scaffolds. Copper-catalysed azide–alkyne cycloaddition reaction, also referred to as the ‘Click’ reaction, producing 1, 4-disubstituted-1, 2, 3-triazoles (‘Click’ triazoles) is one of that kind. 1-(2-Picolyl)-, 4-(2-picolyl)-, 1-(2-pyridyl)-, and 4-(2-pyridyl)-3-methyl-1, 2, 3-triazolium salts have been synthesized and tested for their anticancer activity on human cervical carcinoma HeLa cells. In general, the analogues that are functionalized at the triazole ring with strongly electron donating substituent were more potent in comparison to those with the electron neutral or electron accepting groups. The most active compound was 4-(4-methoxyphenyl)-3-methyl-1-(2-picolyl)-1H-1, 2, 3-triazolium hexafluorophosphate(V) (AB144), with very high cytotoxicity. Its anticancer activity was cell type dependent, being most cytotoxic against large-cell lung carcinoma H460 cells. It is of outmost importance that AB144 was significantly more cytotoxic against tumor cells than to normal cells, with very low therapeutic index (0.0658) for H460 cells. Additionally, this compound was similarly cytotoxic against parent laryngeal carcinoma HEp-2 cells and their carboplatin and cisplatin resistant 7T subline what is, having in mind the importance of inhibitory effect of drug resistance on the success of cancer treatment, of great importance. On the basis of the structural features of triazolium salts it was anticipated that DNA would be the primary target. The fact that no influence of AB144 on thermal stability of calf thymus DNA could be observed, however, discarded this possibility. Compound AB144 arrests tumor cells in the G1 phase of the cell cycle, and induces apoptosis. While our data suggest that the triazolium salt AB144 is an anticancer molecule which preferentially target malignant cells, it holds a promise as simple to make, low molecular mass, non-metalic potential anti-cancer agents.
