Nephrotoxicity is the major limitation for the clinical use of cisplatin as an anti-tumoural drug. Intracellular effects of cisplatin cause tubular damage and tubular dysfunction with sodium, potassium, and magnesium wasting. Renoperotective strategies against cisplatin are classified on 8 targets: 1) Decrease of cisplatin uptake by renal cell, 2) Inhibition of cisplatin metabolism, 3) Blocking cell death pathways, 4) Cyclin-dependent kinase inhibitors, 5) Pharmacologic, molecular, and genetic blockade of p53, 6) Inhibition of specific Mitogen-activated protein kinase, 7) Antioxidants usage for renoprotection against cisplatin injury and inhibit of oxidative stress, 8) Suppress of inflammation. The oxidation reactions can produce free radicals, which start chain reactions and subsequently can cause a large number of diseases in humans. Antioxidant from natural products have attracted the physicians' attentions, nowadays. The natural product antioxidants detoxify reactive oxygen species (ROS) in kidneys, without affecting the anticancer efficacy of cisplatin. Hence, antioxidants have potential therapeutic applications.
肾毒性是顺铂作为抗肿瘤药物临床应用的主要限制因素。顺铂的细胞内作用会导致肾小管损伤和肾小管功能障碍,伴有钠、钾和镁的流失。针对顺铂的肾保护策略可分为8个靶点:1)减少肾细胞对顺铂的摄取;2)抑制顺铂代谢;3)阻断细胞死亡途径;4)细胞周期蛋白依赖性激酶抑制剂;5)对p53进行药理学、分子学和遗传学阻断;6)抑制特定的丝裂原活化蛋白激酶;7)使用抗氧化剂对顺铂损伤进行肾保护并抑制氧化应激;8)抑制炎症。氧化反应会产生自由基,自由基引发连锁反应,随后可导致人类患上大量疾病。如今,天然产物中的抗氧化剂已引起医生们的关注。天然产物抗氧化剂可清除肾脏中的活性氧(ROS),而不影响顺铂的抗癌疗效。因此,抗氧化剂具有潜在的治疗应用价值。
