مقدمه : داروی oxaliplatin داروی ضدسرطانی است که نتایج امیدوارکننده‌ای در درمان سرطان پستان نشان داده است. با این وجود، کارکرد بالینی آن توسط عوارض جانبی محدود کننده دوز و فعالیت ضدتومور کم به خاطر تجمع کم آن در بافت تومور تحت تأثیر قرار گرفته است. بنابراین نیاز مبرمی برای گسترش سیستم دارورسانی هدفمندی برای این دارو احساس می‌شود. در این مطالعه روش‌های جدیدی برای ساخت نانوذرات هدفمند غیرفعال حا...
Background & objectives: Oxaliplatin is a third-generation of platinum drug which is the main therapeutic agent for the treatment of colorectal cancer. Oxaliplatin not only inhibits DNA replication but also transcription and also induces apoptosis or necrosis in cancer cells and rapidly dividing cell lines. Although it is widely used clinically, there is no enough information regarding its ef...
Oxaliplatin is widely used to treat colorectal cancer, as both adjuvant therapy for resected disease and palliative treatment of metastatic disease. However, a significant number of patients experience serious side effects, including prolonged neurotoxicity, from oxaliplatin treatment creating an urgent need for biomarkers of oxaliplatin response or resistance to direct therapy to those most li...
Chemotherapeutic regimens for the treatment of colorectal cancer generally include oxaliplatin, although inherent and acquired resistance is common. One potential mediator of oxaliplatin sensitivity is the nonreceptor protein tyrosine kinase, Src, the activity of which correlates with disease stage and patient survival. Therefore, we investigated the effects of Src inhibition using the tyrosine...

BACKGROUND Mass spectrometric (MS) detection of intact hemoglobin (Hb) adducts presents considerable analytical challenges because of the noncovalent association of the 4 subunits of Hb, and MS characterization of the interaction of intact Hb with platinum drugs has not been reported. We developed a technique for detecting intact Hb and its drug adduct and studied the interactions between intac...
Oxaliplatin is widely regarded as being active in cisplatin-resistant cancer. We undertook a systematic review of the literature to identify, describe and critique the clinical and pre-clinical evidence for the use of oxaliplatin in patients with "cisplatin-resistant" cancer. We identified 25 pre-clinical cell models of platinum resistance and 24 clinical trials reporting oxaliplatin based salv...
BACKGROUND Patients with colorectal cancer treated with oxaliplatin are at risk of hypersensitivity reactions, with the incidence estimated to be 12%-20%. Coinfusion of dexamethasone and oxaliplatin could potentially reduce the incidence of these reactions, but oxaliplatin is reported to be incompatible with alkaline compounds in solution. However, in a previous retrospective study we found tha...
BACKGROUND The majority of patients receiving the platinum-based chemotherapy drug oxaliplatin develop peripheral neurotoxicity. Because this neurotoxicity involves ROS production, we investigated the efficacy of mangafodipir, a molecule that has antioxidant properties and is approved for use as an MRI contrast enhancer. METHODS The effects of mangafodipir were examined in mice following trea...
Oxaliplatin is a thirdgeneration platinum antineoplastic agent. The 2aminocyclohexaneplatinum DNA that oxaliplatin forms is more hydrophobic than that formed by cisplatin and carboplatin. 1 The renal toxicity of oxaliplatin is milder than cisplatin, while its bone marrow suppression action is weaker than carboplatin. Nervous system toxicity is the main doselimiting side effect for oxalipla...
