Abstract
Myocardial fibrosis is a pathological feature of doxorubicin-induced chronic cardiotoxicity that severely affects the prognosis of oncology patients. However, the specific cellular and molecular mediators driving doxorubicin-induced cardiac fibrosis, and the relative impact of different cell populations on cardiac fibrosis, remain unclear.This study aimed to explore the mechanism of doxorubicin-induced cardiotoxicity and myocardial fibrosis and to find potential therapeutic targets. Single-cell RNA sequencing was used to analyze the transcriptome of non-cardiomyocytes from normal and doxorubicin-induced chronic cardiotoxicity in mouse model heart tissue.We established a mouse model of doxorubicin-induced cardiotoxicity with a well-defined fibrotic phenotype. Analysis of single-cell sequencing results showed that fibroblasts were the major origin of extracellular matrix in doxorubicin-induced myocardial fibrosis. Further resolution of fibroblast subclusters showed that resting fibroblasts were converted to matrifibrocytes and then to myofibroblasts to participate in the myocardial remodeling process in response to doxorubicin treatment. Ctsb expression was significantly upregulated in fibroblasts after doxorubicin-induced.This study provides a comprehensive map of the non-cardiomyocyte landscape at high resolution, reveals multiple cell populations contributing to pathological remodeling of the cardiac extracellular matrix, and identifies major cellular sources of myofibroblasts and dynamic gene-expression changes in fibroblast activation. Finally, we used this strategy to detect potential therapeutic targets and identified Ctsb as a specific target for fibroblasts in doxorubicin-induced myocardial fibrosis.

Abstract
The intracellular interactions of biomolecules can be maneuvered to redirect signaling, reprogram the cell cycle, or decrease infectivity using only a few dozen atoms. Such "molecular glues," which can drive both novel and known interactions between protein partners, represent an enticing therapeutic strategy. Here, we review the methods and approaches that have led to the identification of small-molecule molecular glues. We first classify current FDA-approved molecular glues to facilitate the selection of discovery methods. We then survey two broad discovery method strategies, where we highlight the importance of factors such as experimental conditions, software packages, and genetic tools for success. We hope that this curation of methodologies for directed discovery will inspire diverse research efforts targeting a multitude of human diseases.

Abstract
Cardio-oncology is a rapidly growing field in cardiology that focuses on the management of cardiovascular toxicities associated with cancer-directed therapies. Tumor hypoxia is a central driver of pathologic tumor growth, metastasis, and chemo-resistance. In addition, conditions that mimic hypoxia (pseudo-hypoxia) play a causal role in the pathogenesis of numerous types of cancer, including renal cell carcinoma. Therefore, therapies targeted at hypoxia signaling pathways have emerged over the past several years. Though efficacious, these therapies are associated with significant cardiovascular toxicities, ranging from hypertension to cardiomyopathy. This review focuses on oxygen metabolism in tumorigenesis, the role of targeting hypoxia signaling in cancer therapy, and the relevance of oxygen metabolism in cardio-oncology. This review will specifically focus on hypoxia signaling mediated by hypoxia-inducible factors and the prolyl hydroxylase oxygen-sensing enzymes, the cardiovascular effects of specific cancer targeted therapies mediated on VEGF and HIF signaling, hypoxic signaling in cardiovascular disease, and the role of oxygen in anthracycline cardiotoxicity. The implications of these therapies on myocardial biology and cardiac function are discussed, underlining the fine balance of hypoxia signaling in cardiac homeostasis. Understanding these cardiovascular toxicities will be important to optimize treatment for cancer patients while mitigating potentially severe cardiovascular side effects.

Abstract
The anticancer drug dasatinib (Sprycel) is a BCR-ABL1-targeted tyrosine kinase inhibitor used in treating chronic myelogenous leukemia that has been shown in clinical trials to display cardiovascular toxicities. While dasatinib potently inhibits BCR-ABL1, it is not a highly selective kinase inhibitor and may have off-target effects. A neonatal rat cardiac myocyte model was used to investigate potential mechanisms by which dasatinib damaged myocytes. The anthracycline cardioprotective drug dexrazoxane was shown to be ineffective in preventing dasatinib-induced myocyte damage. Dasatinib treatment increased doxorubicin accumulation in myocytes and doxorubicin-induced myocyte damage, likely through its ability to bind to one or more ABC-type efflux transporters. Dasatinib induced myocyte damage either after a brief treatment that mimicked the clinical situation, or more potently after continuous treatment. Dasatinib slightly induced apoptosis in myocytes as evidenced by increases in caspase-3/7 activity. Dasatinib treatment reduced pERK levels in myocytes most likely through inhibition of RAF, which dasatinib strongly inhibits. Thus, inhibition of the RAF/MEK/ERK pro-survival pathway in the heart may be, in part, a mechanism by which dasatinib induces cardiovascular toxicity.

Inadvertent intrathecal administration of daunomycin resulting in fatality: Case report and therapeutic considerations. eNeurologicalSci 2020; 22:100297.

Abstract
Background Daunomycin is a chemotherapeutic agent of the anthracycline family that is administered intravenously, most commonly in combination therapy. The authors report the first known adult case of inadvertently administered daunomycin directly into the human central nervous system and the neurologic manifestations and therapeutic interventions that followed. Clinical description A 53-year-old male presenting to the hospital for his second cycle of consolidation therapy for acute promyelocytic leukemia t(15;17) was accidentally administered 93 mg of intrathecal (IT) daunomycin. Within several hours of injection, the patient subsequently developed bilateral lower extremity pain, ascending paresthesias, headache, and left cranial nerve (CN) III palsy. Immediately following these neurologic sequalae, a subarachnoid lumbar drain was placed at the L4-5 interspace for the initial irrigation and drainage of cerebrospinal fluid (CSF). By hospital day 2, the patient's mental status significantly declined requiring an external ventricular drain (EVD) for hydrocephalus. Despite therapeutic interventions, the patient developed an ascending radiculomyeloencephalopathy with deterioration in clinical status. Eighteen days after the inadvertent injection of IT daunomycin, the patient became comatose and lost all cranial nerve function. Conclusions Accidental IT injection of daunomycin is a neurosurgical emergency and warrants prompt intervention. Symptoms can mimic other medical conditions, making it imperative an accurate diagnosis is made so that appropriate therapies are implemented. At this time, therapies include rapid removal of the chemotherapeutic agent from the IT compartment by aspiration and irrigation; however, it is unclear if neuroprotective agents may provide added benefit. The inadvertent intrathecal injection of daunomycin is fatal. Accurate diagnosis is difficult as symptoms often mimic other conditions. Cerebral spinal fluid lavage and continuous drainage should be initiated. Neuroprotective agents may be considered for salvage therapy.

Antianemia Drug Roxadustat (FG-4592) Protects Against Doxorubicin-Induced Cardiotoxicity by Targeting Antiapoptotic and Antioxidative Pathways. Front Pharmacol 2020; 11:1191.

Abstract
Doxorubicin (DOX) is broadly used in treating various malignant tumors. However, its cardiotoxicity limits its clinical use. Roxadustat (FG-4592) is a new hypoxia-inducible factor prolyl hydroxylase (HIF-PHD) inhibitor and has been approved for treating anemia in chronic kidney diseases (CKD) patients. However, the role of FG-4592 in DOX-induced cardiotoxicity remains unknown. In this study, mouse cardiac function was evaluated by echocardiography, plasma LDH/CK-MB, and heart HE staining. Cell viability, apoptosis, oxidative stress, inflammation, and HIF-target genes were evaluated in mouse cardiac tissue and cardiac cells exposed to DOX with FG-4592 pretreatment. DOX-sensitive HepG2 and MCF-7 cell lines were used to evaluate FG-4592 effect on the anticancer activity of DOX. We found that FG-4592 alleviated DOX-induced cardiotoxicity shown by the protection against cardiac dysfunction, cardiac apoptosis, and oxidative stress without the effect on inflammatory response. FG-4592 alone did not change the cardiac function, cardiomyocyte morphology, oxidative stress, and inflammation in vivo. FG-4592 could protect cardiomyocytes against DOX-induced apoptosis and ROS production in line with the upregulation of HIF-1α and its target genes of Bcl-2 and SOD2. Importantly, FG-4592 displayed anticancer property in cancer cells treated with or without DOX. These findings highlighted the protective effect of FG-4592 on DOX-induced cardiotoxicity possibly through upregulating HIF-1α and its target genes antagonizing apoptosis and oxidative stress.

Tetrandrine Attenuated Doxorubicin-Induced Acute Cardiac Injury in Mice. BIOMED RESEARCH INTERNATIONAL 2020; 2020:2616024.

Abstract
Oxidative damage is closely involved in the development of doxorubicin- (DOX-) induced cardiotoxicity. It has been reported that tetrandrine can prevent the development of cardiac hypertrophy by suppressing reactive oxygen species- (ROS-) dependent signaling pathways in mice. However, whether tetrandrine could attenuate DOX-related cardiotoxicity remains unclear. To explore the protective effect of tetrandrine, mice were orally given a dose of tetrandrine (50 mg/kg) for 4 days beginning one day before DOX injection. To induce acute cardiac injury, the mice were exposed to a single intraperitoneal injection of DOX (15 mg/kg). The data in our study showed that tetrandrine prevented DOX-related whole-body wasting and heart atrophy, decreased markers of cardiac injury, and improved cardiac function in mice. Moreover, tetrandrine supplementation protected the mice against oxidative damage and myocardial apoptotic death. Tetrandrine supplementation also reduced ROS production and improved cell viability after DOX exposure in vitro. We also found that tetrandrine supplementation increased nuclear factor (erythroid-derived 2)-like 2 (Nrf2) expression and activity in vivo and in vitro. The protection of tetrandrine supplementation was blocked by Nrf2 deficiency in mice. In conclusion, our study found that tetrandrine could improve cardiac function and prevent the development of DOX-related cardiac injury through activation of Nrf2.

Abstract
Doxorubicin (DOX) is a highly effective anticancer anthracycline drug, but its side effects at the level of the heart has limited its widespread clinical application. Melatonin is a documented potent antioxidant, nontoxic and cardioprotective agent, and it is involved in maintaining mitochondrial homeostasis and function. The present study established acute DOX-induced cardiotoxicity models in both H9c2 cells incubated with 1 μM DOX and C57BL/6 mice treated with DOX (20 mg/kg cumulative dose). Melatonin markedly alleviated the DOX-induced acute cardiac dysfunction and myocardial injury. Both in vivo and in vitro studies verified that melatonin inhibited DOX-induced mitochondrial dysfunction and morphological disorders, apoptosis, and oxidative stress via the activation of AMPK and upregulation of PGC1α with its downstream signaling (NRF1, TFAM and UCP2). These effects were reversed by the use of AMPK siRNA or PGC1α siRNA in H9c2 cells, and were also negated by the cotreatment with AMPK inhibitor Compound C in vivo. Moreover, PGC1α knockdown was without effect on the AMPK phosphorylation induced by melatonin in the DOX treated H9c2 cells. Therefore, AMPK/PGC1α pathway activation may represent a new mechanism for melatonin exerted protection against acute DOX cardiotoxicity through preservation of mitochondrial homeostasis and alleviation of oxidative stress and apoptosis.

Abstract
Bortezomib and carfilzomib are anticancer drugs that target the proteasome. However, these agents have been shown to exhibit some specific cardiac toxicities by as yet unknown mechanisms. Bortezomib and carfilzomib are also being used clinically in combination with doxorubicin, which is also cardiotoxic. A primary neonatal rat myocyte model was used to study these cardiotoxic mechanisms. Exposure to submicromolar concentrations of bortezomib and carfilzomib resulted in significant myocyte damage and induced apoptosis. Both bortezomib and carfilzomib inhibited the chymotrypsin-like proteasomal activity of myocyte lysate in the low nanomolar concentration range and exhibited time-dependent inhibition kinetics. The high sensitivity of myocytes, which were determined to contain high specific levels of chymotrypsin-like proteasomal activity, to the damaging effects of bortezomib and carfilzomib was likely due to the inhibition of proteasomal-dependent ongoing sarcomeric protein turnover. A brief preexposure of myocytes to non-toxic nanomolar concentrations of bortezomib or carfilzomib greatly increased doxorubicin-mediated damage, which suggests that the combination of doxorubicin with either bortezomib or carfilzomib may produce more than additive cardiotoxicity. The doxorubicin cardioprotective agent dexrazoxane partially protected myocytes from doxorubicin plus bortezomib or carfilzomib treatment, in spite of the fact that bortezomib and carfilzomib inhibited the dexrazoxane-induced decreases in topoisomerase IIβ protein levels in myocytes. These latter results suggest that the doxorubicin cardioprotective effects of dexrazoxane and the doxorubicin-mediated cardiotoxicity were not exclusively due to targeting of topoisomerase IIβ.

Abstract
Extravasation injuries are common emergencies in clinical practice. If they are not recognized and treated promptly, they can lead to deleterious functional and cosmetic outcomes. There is a vast range of agents involved in these injuries and marked paucity of evidence to support their specific management. Following an extensive literature review, we outline management principles for clinicians involved in the care of patients with extravasation injuries. Key parameters in deciding appropriate management plans include the volume/toxicity of the agent, the necrosis interval of the injury, patient-related factors, as well as the facilities and expertise available in the setting of individual cases of extravasation.

Abstract
Extravasation of cytotoxic agents is a true medical emergency. Dexrazoxane is the only licensed drug for the treatment of anthracycline extravasations. Dexrazoxane proved to be effective and moderately well tolerated. However, alternative approaches for the management of anthracycline extravasations are available such as topical DMSO and cooling. There appears to be general agreement about dexrazoxane usefulness when extravasations involve large volumes of anthracycline and/or central venous access device. Nevertheless, the non-invasive combination of DMSO and cooling is the most commonly described therapy, particularly in small anthracycline extravasations. Further research is still needed to establish unequivocal situations where dexrazoxane must be initiated.

Abstract
Extravasation is recognised as a major complication of administering intravenous chemotherapy treatment. Of the agents involved in extravasation, anthracyclines are associated with the greatest risk to patients because they are vesicant agents, having the potential to cause blistering and ulceration. If not identified and left untreated, anthracycline extravasation can lead to more serious complications such as tissue necrosis and functional impairment. Dexrazoxane (Savene(®) ) is the only licensed antidote for the treatment of anthracycline extravasation and clinical evidence has shown Savene(®) to be highly effective for preventing the need for surgery following anthracycline extravasation, allowing full recovery in the majority of patients. To date, there have been eight published studies reporting a total of 102 cases of Savene(®) use. Here, we review the published data on the efficacy of Savene(®) and present an analysis of 12 UK case studies. All UK oncology centres where Savene(®) has been used to manage anthracycline extravasation were contacted by SpePharm UK, who requested case studies for this publication. All of the cases received, including two from our own experience of using Savene(®) have been included in the analysis.

Abstract
The cumulative cardiac toxicity of the anthracycline antibiotics and their propensity to produce severe tissue injury following extravasation from a peripheral vein during intravenous administration remain significant problems in clinical oncologic practice. Understanding of the free radical metabolism of these drugs and their interactions with iron proteins led to the development of dexrazoxane, an analogue of EDTA with intrinsic antineoplastic activity as well as strong iron binding properties, as both a prospective cardioprotective therapy for patients receiving anthracyclines and as an effective treatment for anthracycline extravasations. In this review, the molecular mechanisms by which the anthracyclines generate reactive oxygen species and interact with intracellular iron are examined to understand the cardioprotective mechanism of action of dexrazoxane and its ability to protect the subcutaneous tissues from anthracycline-induced tissue necrosis.

Abstract
OBJECTIVE To present current developments in the specific management of extravasations of antineoplastic agents after the extravasation. METHOD We conducted a search in PubMed, Medline and IDIS-Iowa to identify papers written in English or Spanish that described new specific measures for the management of extravasations. We also reviewed the references given in these papers and recent tertiary sources related to oncology or cytostatic agents. The search covered the period between 1997 and 2010. RESULTS There are only specific measures for the treatment of extravasations of 22 cytostatic agents. These measures are presented for each cytostatic agent, according their drug group. CONCLUSIONS Although currently there is no general consensus on the specific management of antineoplastic agents after extravasation, this review outlines the information collected and published so far, so that it may be of use to any national health centre where cytostatic drugs are prescribed, handled or administered.

Abstract
OBJECTIVE To present a clinical update on the prevention, detection, and evidence-based management of vesicant chemotherapy extravasations. DATA SOURCES Journal articles, published and unpublished case reports, personal experience. CONCLUSION In the 4 years that have elapsed since the publication of the original article, much more is known about vesicant chemotherapy extravasation, and effective evidence-based treatments now are available. The antidotes sodium thiosulfate for mechlorethamine extravasations and hyaluronidase for plant alkaloid extravasations are recommended by the manufacturers of these vesicants and cited in nursing guidelines. The anthracycline extravasation treatment dexrazoxane for injection, the first and only extravasation treatment with proven effectiveness, is now available as Totect (dexrazoxane; TopoTarget USA, Rockaway, NJ, USA) in the US and Savene (SpePharm, Amsterdam, The Netherlands) in Europe. IMPLICATIONS FOR NURSING PRACTICE Nurses who administer vesicant chemotherapy agents need to be aware of the most current evidence (or lack of evidence) for various types of extravasation treatment. Well-informed nurses are patient advocates and instrumental in detecting, managing, and documenting extravasations. Most importantly, nurses play a key role in preventing vesicant chemotherapy extravasations.

Abstract
INTRODUCTION Oxidative stress (caused by excess iron) can result in tissue damage, organ failure and finally death, unless treated by iron chelators. The causative factor in the etiology of a variety of disease states is the presence of iron-generated reactive oxygen species (ROS), which can result in cell damage or which can affect the signaling pathways involved in cell necrosis-apoptosis or organ fibrosis, cancer, neurodegeneration and cardiovascular, hepatic or renal dysfunctions. Iron chelators can reduce oxidative stress by the removal of iron from target tissues. Equally as important, removal of iron from the active site of enzymes that play key roles in various diseases can be of considerable benefit to the patients. AREAS COVERED This review focuses on iron chelators used as therapeutic agents. The importance of iron in oxidative damage is discussed, along with the three clinically approved iron chelators. EXPERT OPINION A number of iron chelators are used as approved therapeutic agents in the treatment of thalassemia major, asthma, fungal infections and cancer. However, as our knowledge about the biochemistry of iron and its role in etiologies of seemingly unrelated diseases increases, new applications of the approved iron chelators, as well as the development of new iron chelators, present challenging opportunities in the areas of drug discovery and development.

Abstract
Renal vascular access is pivotal in the care of the haemodialysis patient; however, it remains a significant challenge to maintain vascular access in the dialysis population. There are a number of renal vascular accesses in use: arteriovenous fistula, arteriovenous graft, and central venous catheter, with the arteriovenous fistula being the ideal choice. Poor vascular access can lead to serious consequences for patients, resulting in morbidity and even mortality. There are also significant cost implications for healthcare providers in terms of hospital admissions, and other associated costs for patients who are admitted late for vascular access referral or as a result of associated complications of vascular access. The nurse and other members of the healthcare team are fundamental in the management of a patient's renal vascular access.

Successful dexrazoxane treatment of a potentially severe extravasation of concentrated doxorubicin. Anticancer Drugs 2010; 21:790-4.

Abstract
Dexrazoxane is now authorized for the treatment of anthracycline extravasations. Several clinical cases of doxorubicin extravasation treated with dexrazoxane have been reported to date, but detailed cases have not been published. We report a case of a successful dexrazoxane treatment for a potentially severe extravasation of concentrated doxorubicin. We also describe objective outcome of this treatment, drug tolerance to dexrazoxane and long follow-up. A 29-year-old man diagnosed with Hodgkin's lymphoma was prescribed a regimen including 90 mg of doxorubicin in a 50 ml infusion using a reduced occlusion infusion pump. After this infusion, the patient complained of pain around the site of injection and presented a 10x6-cm swollen area with erythema and inflammation. A significant portion of doxorubicin was extravasated. Dexrazoxane was prescribed as an antidote. Side effects of dexrazoxane were restricted to reversible hematological toxicity, nausea, and vomiting. The next day, the inflammation of the extravasation area was reduced. On day 7, a painless mild induration in the extravasated area was the only remaining sign of the extravasation. On day 40, an arm nuclear magnetic resonance image showed no focal injuries. At 6-month follow-up, the patient has no sequelae. The two risk factors that could have increased the severity of the extravasation are the use of an infusion pump and the high drug concentration. Dexrazoxane proved to be effective and moderately well tolerated. A dexrazoxane stock in oncological facilities could help to promptly handle emergencies like this. Anthracyclines can be administered using reduced occlusion infusion pumps, but it seems preferable to always administer a free-running infusion to minimize accidents like this one.

Abstract
The application of anthracyclines in anticancer therapy may result in accidental extravasation injury and can be a serious complication of their use. Tissue necrosis with skin ulceration is a possible outcome in the inadvertent extravasation of anthracyclines during intravenous administration. Until recently, there has been no effective treatment against the devastating effect of extravasated anthracycline. Preclinical and clinical studies are leading to the clinical implementation of dexrazoxane as the first and only proven antidote in anthracycline extravasation. In two multicenter studies dexrazoxane has proven to be highly effective in preventing skin necrosis and ulceration. This review focuses on the development and management of dexrazoxane in anthracycline extravasation injuries.

Abstract
Anthracycline antibiotics are among the most effective and commonly used anticancer drugs. Unfortunately, their clinical use is restricted by dose-dependent toxicity. Doxorubicin is an anthracycline antibiotic and cytotoxic (antineoplastic) agent. It is commonly used against ovarian, breast, lung, uterine and cervical cancers, Hodgkin's disease, soft tissue and primary bone sarcomas, as well against in several other cancer types. It has been shown that free radicals are involved in doxorubicin-induced toxicity. Doxorubicin causes the generation of free radicals and the induction of oxidative stress, associated with cellular injury. This review illustrates recent applications of different natural products, drugs, drug delivery systems, and approaches for protection against doxorubicin-induced toxicity (2006-present).

Abstract
The anticancer tyrosine kinase inhibitor sunitinib has been shown recently to be cardiotoxic. Using a neonatal rat myocyte model, we investigated various mechanisms that might be responsible for its cardiotoxicity. Sunitinib potently inhibited the enzyme activity of both AMP-activated protein kinase (AMPK) and the ribosomal S6 kinase RSK1 at therapeutically relevant concentrations. Heart tissue with its high energy needs might be particularly sensitive to inhibition of AMPK because of its role as an energy sensor regulating ATP levels. As measured by lactate dehydrogenase release, sunitinib treatment of myocytes caused dose-dependent damage at therapeutic levels. Sunitinib treatment also caused a dose-dependent reduction in myocyte protein levels of the phosphorylated alpha and beta isoforms of the AMPK phosphorylation target acetyl-Coenzyme A carboxylase. However, myocytes were not protected from sunitinib treatment by pretreating them with the AMPK-activating antidiabetic drug metformin. Sunitinib treatment of myocytes also did not affect cellular ATP levels. Together, these last two results do not suggest a major role for inhibition of AMPK in sunitinib-induced myocyte damage. Dexrazoxane, which is a clinically approved doxorubicin cardioprotective agent, also did not protect myocytes from damage, which suggests that sunitinib did not induce oxidative damage. In conclusion, even though sunitinib potently inhibits AMPK and RSK1, given the extreme lack of kinase selectivity that sunitinib exhibits, it is likely that inhibition of other kinases or combinations of kinases are responsible for the cardiotoxic effects of sunitinib.

Abstract
Dexrazoxane (ICRF-187) is clinically used as a doxorubicin cardioprotective agent and to prevent anthracycline extravasation injury. It may act by preventing iron-based oxygen free radical damage through the iron-chelating ability of its metabolite N,N'-[(1S)-1-methyl-1,2-ethanediyl]bis[(N-(2-amino-2-oxoethyl)]glycine (ADR-925). Dexrazoxane undergoes an initial metabolism to its two one-ring open intermediates [N-(2-amino-2-oxoethyl)-N-[(1S)-2-(3,5-dioxo-1-piperazinyl)-1-methylethyl]glycine (B) and N-(2-amino-2-oxoethyl)-N-[(2S)-2-(3,5-dioxo-1-piperazinyl)propyl]glycine (C)] and is then further metabolized to its presumably active metal-chelating form ADR-925. We previously showed that the first ring opening reaction is catalyzed by dihydropyrimidinase and the second by dihydroorotase (DHOase), but not vice versa. To determine whether DHOase was important in the metabolism of dexrazoxane, its metabolism and that of B and C to ADR-925 were measured in rats that were pretreated with the DHOase inhibitor 5-aminoorotic acid. In rats pretreated with 5-aminoorotic acid the area-under-the-curve concentration of ADR-925 was reduced 5.3-fold. In rats treated with a mixture of B and C, the maximum concentration of ADR-925 in the plasma was significantly decreased in rats pretreated with 5-aminoorotic acid, which indicates that DHOase directly metabolized B and C. Both heart and liver tissue levels of ADR-925 in rats were also greatly reduced by pretreatment with 5-aminoorotic acid. Together these results indicate that the metabolism of dexrazoxane and of B and C is mediated by DHOase. These results provide a mechanistic basis for the antioxidant cardioprotective activity of dexrazoxane.
