It remains to be determined whether the parent compound, its oxidized form, or a specific metabolite is the primary mediator of the observed hepatotoxicity and iron chelation
Although novel therapeutic strategies and targeted therapies, including intraperitoneal administration, poly (ADP-ribose) polymerase (PARP) inhibitors, and anti-angiogenic agents, have been introduced, the five-year survival rate for patients with advanced ovarian cancer (OC) remains approximately 30%
Because this combination is not approved yet, healthcare providers will eventually closely monitor patients for gastrointestinal side effects, such as nausea, vomiting, or constipation, and adjust doses accordingly to maximize benefits while minimizing discomfort
The overall rate of GSH synthesis is controlled by several factors including: (i) availability of the substrate mainly L-cysteine (Anderson and Meister, 1983)
