This study is dedicated to the development of multimodal anticancer agents. We have obtained ruthenium complexes conjugated with the steroid-type antitumor drug abiraterone acetate in order to take advantage of the dual antitumor properties of both ruthenium and abiraterone. The compounds exhibit good antiproliferative activity against cancer cells, with selectivity over primary fibroblasts. Real-time cell analysis revealed that compound dichlorido(η6-p-cymene)(abiraterone acetate)ruthenium(II) had pronounced antiproliferation activity compared to abiraterone acetate. Flow cytometric studies on the mechanism of cell death have revealed that the most active compound induces apoptosis more effectively than abiraterone acetate. Our findings demonstrate the potential of this novel dual-action compound as promising candidates for further development as anticancer agents.
