摘要：
A new mononuclear zinc(II) complex Zn(niacin)2(H2O)4 (1) is synthesized. The interaction of 1 with calf thymus-DNA is investigated by UV-Vis and fluorescence spectrometry, and the apparent binding constant (Kapp) value is established as 4.6 × 105 M–1. It is found that the quenching mechanism between bovine serum albumin and 1 might be a static quenching procedure with one binding site. Further, the anticancer activity of the complex on three human tumor cells lines (HT29, HepG2, and MCF-7) is studied. The IC50 values of 1 on HT29, HepG2, and MCF-7 are 114.1 ± 8, 146.7 ± 14, and 319.2 ± 13 μM, respectively.
