Abstrakt: Herein, we report the synthesis of fluorescent 1,4-dihydropyridine-linked bis-triazoles (2a-2n) through Hantzsch synthesis by the condensation of o/m-chloro-substituted benzaldehyde, ethyl 3-oxo-4(prop-2-yn-1-yloxy)butanoate, and ammonium acetate in the presence of Ba(NO3)2 as a catalyst followed by the click reaction of resultant Hantzsch product (1) with various aromatic as well as aliphatic azides. All the synthesized compounds were well characterized by 1H-NMR, 13C-NMR, FTIR, and HRMS spectral techniques. Antibreast cancer evaluation of all the synthesized derivatives revealed that the compounds 2f (IC50 = 7 ± 0.02 µM) and 2g (IC50 = 5 ± 0.03 µM) showed better anticancer activity (lower IC50) than the standard drug tamoxifen (IC50 = 11.2 ± 0.01 µM) against breast carcinoma (MDA-MB-231) cell line. The synthesized compounds were also screened against normal human embryonic kidney (HEK-293) cell line and found to be nontoxic. The fluorescent nature and cytotoxicity assay of these newly synthesized hybrids recommend their utility in tumor cell imaging. [ABSTRACT FROM AUTHOR]
