Novel organobismuth(III) complex of 5H-dibenzo[c,f][1,5]oxabismocin-12(7H)-yl nitrate (C2) was synthesized and characterized by spectral and elemental analysis. It was compared with other five C,E,C-chelating (E = N, O, S) organobismuth(III) complexes against human adenocarcinoma alveolar basal epithelial cells (A549), human liver cancer cell line (SMCC7721), human gastric cancer cell line (SGC-7901), human colon adenocarcinoma cell line (SW480) and healthy human bronchial cell line (16HBE14o-) in vitro. It was found that C2 exhibited the best anticancer activity. Further mechanistic investiga...
