A series of bis-phenoxyacetic acids 2 were prepared starting from corresponding unsubstituted/substituted 1,4-quinols 1. The fusion of bis-phenoxyacetic acids 2 with thiocarbohydrazide gave the corresponding bis-[4-amino-5-mercapto-1,2,4-triazol-3-yl-methyleneoxy]phenylenes (3) in a one pot reaction. The reaction of bis-triazoles 3 with various reagents afforded N-bridged heterocycles 4-6 in good yields. The newly synthesised compounds were screened for their anticancer activity against a panel of 60 cell lines derived from seven cancer types namely, lung, colon, melanoma, renal, ovarian, CNS and leukemia. Some of the tested compounds showed promising anticancer properties.
