Identifying Cellular Stress-Related mRNA Changes Induced by Novel Xanthone Derivatives in Ovarian Cancer Cells In Vitro

<b>Background:</b> Ovarian cancer is a major challenge in oncology due to high mortality rates, especially in advanced stages, despite current therapeutic approaches relying on chemotherapy and surgery. The search for novel therapeutic strategies is driven by the need for more effective treatments. This study focuses on novel xanthone derivatives modified with a morpholine ring, aiming to improve anticancer efficacy. <b>Methods:</b> In silico studies were conducted using ProTox III and SwissADME databases to assess the toxicity and ADME properties of the synthesized compounds. Molecular changes in cellular stress-related genes were investigated through qPCR in two ovarian cancer cell lines (TOV-21G and SKOV-3) following treatment with the compounds. <b>Results:</b> In silico analyses predicted high gastrointestinal absorption and blood-brain barrier permeability for the derivatives. Compounds exhibited varying toxicity and metabolic profiles. qPCR revealed significant alterations in genes related to antioxidant enzymes, molecular chaperones, and xenobiotic metabolism, indicating potential mechanisms of action and cellular responses to the compounds. <b>Conclusions:</b> The study demonstrates the potential of novel xanthone derivatives as promising candidates for ovarian cancer therapy, with implications for enhancing therapeutic efficacy and addressing drug resistance. Further research is warranted to elucidate the precise mechanisms underlying the observed effects and to develop tailored treatment strategies leveraging these agents.
