One of the widely used anticancer drugs for the treatment of various neoplasms is cyclophosphamide (CYP). The inactive prodrug CYP is metabolized by cytochrome P450 enzyme into active metabolites, phosphoramide mustard and acrolein. The accumulation of acrolein metabolite inside the urothelium results in hemorrhagic cystitis (HC) which is a urotoxic adverse effect associated with the use of CYP. To counteract the occurrence of HC induced by CYP, Mesna is usually used, with allergic reactions reported in some cases. Therefore, several natural products have drawn much attention as alternative safe therapies to reduce the urotoxicity produced from the use of CYP. This review will focus on certain uroprotective mechanisms related to some medicinal plants that are used to ameliorate the CYP-induced urotoxicity in experimental models. The mechanisms involving oxidative stress, inflammation, immune system, apoptosis, DNA fragmentation, uroplakins, purinergic signaling and muscarinic receptors, and CytoP450 metabolism are discussed.
