Sažetak
The synthesis of novel 1, 1′-disubstituted ferrocene conjugates appended with N-1 and O-4 alkylated quinolone and quinoline was reported. The target compounds were synthesized employing a liquid-assisted grinding (LAG) mechanochemical method in copper-catalyzed azide-alkyne cycloaddition (CuAAC) to obtain ferrocene−quinoline/quinolone hybrids (5a–5d, 6a– 6d, 7a, 7b, 8a, and 8b) in higher yields and shorter reaction time compared to a conventional method, thus proving superiority of mechanochemistry versus conventional synthesis. Bis-quinoline and bis-quinolone ferrocene derivatives were evaluated for their antiproliferative effects on five selected tumor and two non-tumor cell lines. Bis-6- methylquinolone–ferrocene conjugate 8b showed the best antiproliferative effect on T-cell lymphoma (HuT78) cells (IC50 = 14.8 μM) and no cytotoxicity on both non-tumor MDCK1 and BJ cells. Results obtained after mitochondrial membrane potential (∆Ψm) measurement using flow cytometry showed that compound 8b caused accumulation of HuT78 cells in subG0/G1 phase, disturbance of mitochondrial membrane potential, and apoptosis. The structure of the quinolone and ferrocene hybrid 8b can be further optimized to obtain candidates with better inhibitory effects on HuT78 cells.
