In silico and in vitro evaluation of oxypeucedanin-induced anticancer activity: Mitotoxicity?

Aim: This study aims to evaluate the alterations in Oxypeucedanin (OXY)-mediated anticancer activity in different media. Second aim is to predict the affinity of OXY to electron transfer chain (ETC) complexes. Materials and Methods: MTT and LDH leakage assays were performed with OXY. Molecular docking studies were also conducted to predict the affinity of OXY to ETC complexes. Results: 250 µM OXY reduced viability in glucose media. ?50 µM OXY decreased viability in galactose media. ?50 µM OXY increased membrane disruption in galactose media. Molecular docking studies also showed that OXY might possess the capacity to bind to the inhibition sites of Complex I and IV. Conclusion: Galactose-conditioned media exacerbated the OXY-mediated cytotoxicity. Preliminary results suggested that mitotoxicity might take part in anticancer activity. Furthermore, OXY might cause ETC dysfunctions due to selective inhibition of Complex I and IV.
