Synthesis and Anticancer Activities of Water Soluble Schiff Base Metal Complexes

In this study, we synthesized the water-soluble Schiff Base containing S, O, N heteroatoms by the condensation reaction from 4-amino-3-hydroxynaphthalene-1-sulfonic acid and 2-hydroxy-3-methoxybenzaldehyde. In addition, Cu (II), Zn (II) and Ni (II) complexes of the ligand were synthesized and characterized by elemental analysis, magnetic susceptibility and spectroscopic techniques such as FT-IR, 1 H-NMR and 13 C-NMR. The anticancer activities of ligand and it’s three metal complexes on A549 lung cancer cell lines were evaluated. Cell viability experiments revealed that Ligand (L) and nickel (II) complex (L-Ni) did not able to inhibit A549 cell proliferation while L-Cu and L-Zn had 12 and 80 µ M of IC 50 values respectively. These last two complexes also induced apoptosis and suppressed cell migration on A549 cells. 2-hidroksi-3-metoksibenzaldehitten kondensasyon reaksiyonu ile S, O, N hetero atomları içeren suda çözünebilir bir Schiff Bazı elde edildi. Ek olarak, ligandın Cu (II), Zn (II) ve Ni (II) kompleksleri sentezlendi ve elementel analiz, manyetik duyarlılık ve FT-IR, 1 H-NMR ve 13 C-NMR gibi spektroskopik tekniklerle karakterize edildi. Ligandın ve üç metal kompleksinin A549 akciğer kanseri hücre hattında antikanser aktiviteleri değerlendirildi. L-Cu ve L-Zn olarak etiketlenmiş Bakır (II) ve Çinko (II) komplekslerinin IC 50 değerleri sırasıyla 12 ve 80 µ M olarak bulundu. L-Cu ve L-Zn komplekslerinin A549 hücrelerinde apoptozu indüklediği ve hücre göçünü inhibe ettiği görüldü. Ligand (L) ve Nikel (II) bileşiklerinin (L-Ni) A549 hücre proliferasyonu üzerinde herhangi bir etki göstermediği belirlendi.
