Özet

New bis-thiazole derivatives (1-10) were synthesized via the ring closure of 1,1'-(3,3'-dimethoxybipheny1-4,4'-diyl)bis(thiourea) with phenacyl bromides and evaluated for their cytotoxic effects on A549 human lung adenocarcinoma, C6 rat glioma, 5RP7 H-ras oncogene transformed rat embryonic fibroblast and NIH/3T3 mouse embryonic fibroblast cell lines using MIT assay. DNA synthesis inhibitory effects of these compounds were investigated. Each derivative was also evaluated for its ability to inhibit AChE and BuChE using a modification of Ellman's spectrophotometric method. Among these compounds, 3,3'-dimethoxy-N-4,N-4'-bis(4-(4-bromophenyl)thiazol-2-yl)-[1,1'-biphenyl]-4,4'-diamine (5) can be identified as the most promising anticancer agent due to its notable inhibitory effects on A549 and C6 cell lines and low toxicity to NIH/3T3 cell lines. Compound 5 exhibited anticancer activity against A549 and C6 cell lines with IC50 values of 37.3 +/- 6.8 mu g/mL and 11.3 +/- 1.2 mu g/mL, whereas mitoxantrone showed anticancer activity against A549 and C6 cell lines with IC50 values of 15.7 +/- 4.0 mu g/mL and 11.0 +/- 1.7 mu g/mL, respectively. Furthermore, compound 5 showed DNA synthesis inhibitory activity against A549 cell line. (C) 2015 Elsevier Masson SAS. All rights reserved.
