Selected 5-amino-1-aryl-1H-1,2,3-triazole scaffolds as promising antiproliferative agents

Development of new effective drugs with low side effects and definite chemical characteristics needs identification of bioactive scaffolds for further structural optimization. New synthesized derivatives of 4-hetaryl-5-amino-1-aryl-1H-1,2,3-triazoles and 3H-[1,2,3]triazolo[4,5-b]pyridines were tested for anticancer activity using 60 human tumor cell lines within 9 cancer types. The selective influence of (5-amino-1H1,2,3-triazol-4-yl)quinazolin-4(3H)-ones: 2-(5-amino-1-(4-chlorophenyl)-1H-1,2,3-triazol-4-yl)quinazolin4(3H)-one and 2-(5-amino-1-phenyl-1H-1,2,3-triazol-4-yl)-6-bromoquinazolin-4(3H)-one on ovarian cancer OVCAR-4 cells with growth percentage (GP) = -4.08 and 6.63%, respectively, was found. The derivative 5,7-diamino-3-(3-(trifluoromethyl)phenyl)-3H-[1,2,3]triazolo[4,5-b]pyridine-6-carbonitrile possessed high activity towards lung cancer EKVX cells (GP = 29.14%). The compounds were shown to be less toxic than doxorubicin towards non-tumor human embryonic kidney cells of HEK293 line. Thus, the results of our study confirm the anticancer potential of compounds based on 5-amino-1-aryl-1H-1,2,3-triazoles scaffolds and their fused polycyclic derivatives.
