Effects of cyclophosphamide and a metabolite, acrolein, on Naegleria fowleri in vitro and in vivo. Neither cyclophosphamide nor serum from cyclophosphamide-treated mice inhibited N. fowleri in vitro. Biochem Pharmacol 1979; 28: 2045–9. Chloroacetaldehyde (CAA), acrolein, and phosphoramide mustard (PM) are cytotoxins, but acrolein and PM are the major toxins because of the abundance of their formation. (2013) Wang et al. Toxicological Sciences. A metabolic product of cyclophosphamide, acrolein, inhibited growth and enflagellation of N. fowleri. Small amounts of acrolein can be formed and can enter the air when trees, tobacco, other plants, gasoline, and oil are burned. Chemotherapy metabolite. AU - McDermott, Catherine. Cyclophosphamide in its parent form does not have direct cytotoxic effects. Cyclophosphamide (CP) is a chemotherapeutic drug with a wide range of applications ranging from treatment of many gynecological cancers to various autoimmune diseases. [21] Acrolein produced during cyclophosphamide treatment collects in the urinary bladder and if untreated can cause hemorrhagic cystitis. Cyclophosphamide appears to induce its own metabolism which results in an overall increase in clearance, increased formation of 4-hydroxyl metabolites, and shortened t1/2 values following repeated administration. Metabolism is complex; CY is administered as a prodrug that is oxidized within hepatocytes to the active metabolite 4-hydroxycyclophosphamide (HCY) by CYP2B6, 3A4, 2C9, and 2A6. Cyclophosphamide cystitis – identification of acrolein as the causative agent. Acrolein, a cyclophosphamide's metabolite induces body to produce superfluous ROS that cause tissues to undergo oxidative stress and/or apoptosis (15). In vitro and in vivo studies revealed that CP induced but did not activate (5-aminolaevulinic acid (ALA) synthase. Background: Cyclophosphamide (CP) is an anticancer alkylating group (nitrogen mustard) and a prodrug that will be metabolized to form its active metabolite, 4-hydroxycyclophosphamide (4-OHCP). Cyclophosphamide (CP), also known as cytophosphane among other names, is a medication used as chemotherapy and to suppress the immune system. Acrolein is a colorless or yellow liquid with a disagreeable odor. AU - Chess-Williams, Russ. Cyclophosphamide (CP) is a widely utilized chemotherapy drug. HCY (4-hydroxy-cyclophosphamide) is formed primarily in the liver but circulates in blood, entering cells as its tautomer aldocyclophosphamide (AldoCY). Damage to the bladder wall is due to contact with the acrolein metabolite of cyclophosphamide, which causes sloughing, thinning, and inflammation of the e~ithe1ium.l~ From the College of Pharmacy, University of Michigan, Ann Arbor, Michigan. Protection of cynarin, the major compound of CGS, against acrolein cytotoxicity in HepG2 cells was studied. The first step in this activation is hydroxylation to 4-hydroxycyclophosphamide; this metabolite breaks down to form two cytotoxic metabolites, phosphoramide mustard and acrolein. CHLOROACETALDEHYDE, AND NOT ACROLEIN, IS THE MORE URO-TOXIC METABOLITE OF CYCLOPHOSPHAMIDE AND ISOFOSFAMIDE IN VITRO. Cyclophosphamide must be metabolically activated to have maximal mutagenic or teratogenic activity. As chemotherapy it is used to treat lymphoma, multiple myeloma, leukemia, ovarian cancer, breast cancer, small cell lung cancer, neuroblastoma, and sarcoma. Exposure to acrolein also causes 2. In this study, Cichorium glandulosum seed (CGS) effectively mitigated CP-induced hepatotoxicity in mice. The various enzymes involved in its bioactivation can cause a wide range of CP expression and activity among patients and ultimately affect the metabolism, efficacy and toxicity of this drug. Acrolein injured starved cells and amoebae at 5 degrees C and growing N. fowleri. The cyclophosphamide metabolite, acrolein alters urothelial cell viability and reactive oxygen species production at relatively low concentrations (100nM), while the parent drug, at concentrations up to 100µM, does not. The aim of this study is to explore the mechanism by which acrolein (ACR), a metabolite of cyclophosphamide (CP), induces immature Sertoli cell cytoskeletal changes. XTT assays were performed to detect cell viability. Oncology Letters; International Journal of Oncology; Molecular and Clinical Oncology; Experimental and Therapeutic Medicine; International Journal of Molecular Sertoli cells obtained from rats were cultivated and treated with 50 and 100 μM ACR. Metabolism and binding of cyclophosphamide and its metabolite acrolein to rat hepatic microsomal cytochrome P-450. Some studies of cyclophosphamide (CP) and its metabolite acrolein in chick embryo liver were carried out in order to investigate the mechanism of the porphyrinogenic action of CP. of metabolism of cyclophosphamide, as well as the hydration status, urine output, frequency of urination, and concurrent exposure to other urotoxic drugs or genitourinary radiotherapy. Cyclophosphamide can be administered by oral or intravenous route. Cyclophosphamide (CY) is an alkylating agent used frequently for myeloablative conditioning therapy prior to SCT. Acrolein exposure resulted in several structural changes including induced F-actin microfilament aggregation, and marginalization and regionalization in Sertoli cells, which are important in spermatogenesis; such effects may underlie the testicular toxicity of the anticancer drug cyclophosphamide which is metabolized into acrolein (Liu et al., 2012). Objectives: To examine the effects of cyclophosphamide and its metabolite acrolein on procoagulant and anticoagulant pathways in both … 10. The phosphoramide metabolite forms cross-linkages within and between adjacent DNA strands at the guanine N-7 position. N2 - Cyclophosphamide and ifosfamide are commonly used anticancer agents. 3. Sertoli cells obtained from rats were cultivated and treated with 50 and 100 μM ACR. J Urol 1984; 132: 580–2. Summary. Acrolein at 40 microM was amoebicidal. Marinello AJ, Bansal SK, Paul B, Koser PL, Love J, Struck RF, Gurtoo HL. AU - Mills, Kylie. XTT assays were performed to … The mechanism may involve direct injury to the urothelium by acrolein, an active metabolite of cyclophosphamide. Background: Thrombosis is a common complication in cancer patients receiving chemotherapy regimens that include cyclophosphamide.However, the mechanisms by which these agents increase this risk are largely uncharacterized. drugs, or disease (Table 1). 2-Chloroacetaldehyde: a metabolite of cyclophosphamide in the rat. 11 Shaw IC, Graham MI, McLean AE. In previous studies, we suggested that for CY-induced cardiotoxicity, whereas acrolein is the key toxic metabolite, carboxyethylphosphoramide mustard (CEPM) is protective. CP and its metabolite, acrolein, could induce hepatotoxicity. 2. Y1 - 2012. It also burns easily. Hemorrhagic cystitis can develop Acrolein (ə-krōʹ-lē-ĭn, systematic name: propenal) is the simplest unsaturated aldehyde.It is a colourless liquid with a piercing, acrid smell.

The "acrolein … Acrolein is a urinary metabolite from cyclophosphamide and can induce hemorrhagic cystitis. Hypothesis / aims of study: Cyclophosphamide (CPO) and ifosfamide (IFO) are commonly used anticancer and immunosuppressive agents. The aim of this study is to explore the mechanism by which acrolein (ACR), a metabolite of cyclophosphamide (CP), induces immature Sertoli cell cytoskeletal changes. Analytical methods. Cyclophosphamide is a medication primarily used in the management and treatment of neoplasms, including multiple myeloma, ... Aldophosphamide is cleaved to the active alkylating agent phosphoramide mustard and acrolein. Hemorrhagic cystitis is a common complication in children receiving cyclophosphamide, a chemotherapeutic alkylating agent. Cyclophosphamide and ifosfamide treatment results in the production of acrolein. Acrolein is a urinary metabolite of cyclophosphamide and ifosfamide, which has been reported to be the causative agent of hemorrhagic cystitis induced by these compounds. As a sequela of CP exposure many women suffer from premature ovarian insufficiency and infertility.

It dissolves in water very easily and quickly changes to a vapor when heated. Cyclophosphamide (CPA) represents a widely used anti-cancer prodrug that is converted by liver cytochrome P450 (CYP) enzymes into the primary metabolite 4-hydroxycyclophosphamide (4-OH-CPA), followed by non-enzymatic generation of the bioactive metabolites phosphoramide mustard and acrolein. cyclophosphamide cystitis with 2-mercaptoethane sodium sulfonate: a histologic study. In vitro and in vivo studies revealed that CP induced but did The smell of burnt fat (as when cooking oil is heated to its smoke point) is caused by glycerol in the burning fat breaking down into acrolein. August 1988; Antimicrobial Agents and Chemotherapy 32(7):962-5; DOI: 10.1128/AAC.32.7.962. Cyt P450 metabolism produces 4-hydroxycyclophosphamide (an active metabolite) which spontaneously isomerizes to aldophosphamide (a second active metabolite). PY - 2012. CP is metabolized in the liver to give stable toxic compound acrolein. 10 Cox PJ. Cyclophosphamide undergoes activation to eventually form active metabolites, phosphoramide mustard and acrolein.
