Long-chain alkyltriazoles as antitumor agents: synthesis, physicochemical properties, and biological and computational evaluation
摘要:
A series of novel long-chain alkyltriazoles were prepared from commercial diols in a rapid process with good yields. The compounds were evaluated in vitro for their anticancer potential against two human cancer cell lines: colon carcinoma (RKO) and uterine carcinoma (HeLa). The results of colorimetric MTT assays showed that six of fourteen compounds tested decreased cell viability in these cell lines. Compounds 5e and 6a were the most active against RKO cells, with IC50 values of 16.70 and 14.57 mu M, respectively. The same compounds, 5e and 6a, were the most active in HeLa cells as well, with IC50 values of 11.05 and 12.77 mu M, respectively. In addition, compound 5e was found to induce apoptosis in RKO cells, as assessed by TUNEL assay. The results suggest that compound 5e may be a promising prototype anticancer agent.
Leishmanicidal, antiproteolytic, and mutagenic evaluation of alkyltriazoles and alkylphosphocholines
摘要:
A series of 16 simple long-chain alkyltriazoles and two novel alkylphosphocholine derivatives containing an aside moiety were evaluated in vitro for their leishmanicidal activity against. Among the 18 compounds tested, the eight most active compounds against promastigote forms were selected for further evaluation against amastigote forms. These compounds were also evaluated for their cytotoxicity against murine macrophages and tested as inhibitors of cysteine protease rCPB2.8, an important target for development of antileishmanial drugs. The mutagenicity of some of these compounds was also evaluated in prokaryotic and eukaryotic cells to assess any genetic effects of the leishmanicidal candidates. The compound 4, an alkylphosphocholine derivative, was found to be the most potent against amastigote forms with an IC50 of 3.81 mu M, comparable to that of pentamidine (IC50 = 6.62 mu M) and amphotericin B (IC50 = 6.10 mu M), two established leishmanicidal drugs. Compound 4 also exhibited the best selectivity index (SI) values of the series, demonstrating low toxicity against macrophages and a cLogP value higher than 5. Among the alkyltriazoles,, compounds 13 and 14 were the most active against promastigote and amastigote forms. They were then evaluated for their mutagenicity in vitro; the mutagenicity index (MI) values were lower than 2, suggesting that these compounds are not mutagenic. (C) 2015 Elsevier Masson SAS.
