Abstract
In this work, we present a recently developed ruthenium complex that shows anticancer activity in gallbladder cancer cells. After the synthesis of the new ruthenium complexes, the antiproliferative, cytotoxicity, and apoptosis activities were evaluated in vitro by the triple assay ApoTox-Glo. Then, the transcription levels of genes related to apoptosis were evaluated by real-time PCR (q-PCR). The ruthenium complex, called Ru-UCN3, inhibits the proliferation of gallbladder cancer cells G-415 by means of apoptosis, which was demonstrated by the overexpression of the pro-apoptotic genes Puma, Diablo, and Caspasa-9 together with the repression of the anti-apoptotic genes Bcl-xL and Bcl-2. In addition, we found strong caspase 3/7 activity in the cells at 24h of the Ru-UCN3 exposure, which was evaluated by the triple ApoTox-Glo assay. The new ruthenium complexes evaluated had an inhibitory effect on G-415 cells. We think that Ru-UCN3 could be a promising anticancer agent, which should be explored with more in vitro and in vivo assays and probably with the chemical modulation of this molecule.
