Hammoodi HZ, Al-Shawi NN. Neuroprotective effects of daidzein against ifosfamide-induced neurotoxicity in male rats: role of selected inflammatory and apoptotic markers. J Med Life 2023; 16:1628-1632. [PMID: 38406792 PMCID: PMC10893576 DOI: 10.25122/jml-2023-0082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Accepted: 05/13/2023] [Indexed: 02/27/2024] Open
Abstract
Ifosfamide (IFO), an alkylating chemotherapy agent, is known for its association with neurotoxicity and encephalopathy. This trial was designed to evaluate the protective action of daidzein (DZN) against IFO-induced neurotoxicity in male rats by determining the difference in certain inflammatory and apoptotic markers in the brain tissue of rats. Twenty-eight Wistar rats, weighing 120-150 g, were divided into four groups of seven rats: Group 1 (Control) received no treatment; Group 2 was orally administered DZN (100 mg/kg/day) for seven days; Group 3 received a single intraperitoneal (IP) dose of IFO (500 mg/kg); Group 4 received oral DZN (100 mg/kg/day) for one week prior to a single IP dose of IFO on the seventh day. Twenty-four hours post-treatment, serum and brain tissue samples were collected for analysis. The results indicated a significant increase in serum inflammatory markers (TNF-alpha, IL-6, and iNOS) and the anti-inflammatory marker (IL-10), along with elevated caspase-3 enzyme activity in the brain tissue of the IFO-treated group compared to the control group. Conversely, pre-treatment with DZN significantly reduced serum inflammatory markers and caspase-3 levels in tissue. The findings suggest that daidzein has anti-inflammatory and anti-apoptotic properties, potentially offering protection against IFO-induced neurotoxicity in rats.

Phenolic Acids and Prevention of Cognitive Decline: Polyphenols with a Neuroprotective Role in Cognitive Disorders and Alzheimer's Disease. Nutrients 2022.

Abstract
Cognitive impairment, also known as cognitive decline, can occur gradually or suddenly and can be temporary or more permanent. It represents an increasingly important public health problem and can depend on normal aging or be linked to different neurodegenerative disorders, including Alzheimer's disease (AD). It is now well-established that lifestyle factors including dietary patterns play an important role in healthy aging as well as in the prevention of cognitive decline in later life. Among the natural compounds, dietary polyphenols including phenolic acids have been recently the focus of major attention, with their supplementation being associated with better cognitive status and prevention of cognitive decline. Despite their therapeutic potential, human studies investigating the relation between phenolic acids intake and cognitive outcomes are rather scarce. In this review, we provide preclinical evidence that different dietary polyphenols such as rosmarinic acid, ellagic acid, and cinnamic aldehyde can exert neuroprotective and pro-cognitive activities through different molecular mechanisms including the modulation of pro-oxidant and antioxidant machinery as well as inflammatory status. Future and more numerous in vivo studies are needed to strengthen the promising results obtained at the preclinical level. Despite the excellent pharmacokinetic properties of phenolic acids, which are able to be accumulated in the brain at pharmacologically relevant levels, future studies should also identify which among the different metabolites produced as a consequence of phenolic acids' consumption may be responsible for the potential neuroprotective effects of this subgroup of polyphenols.

Abstract
Ifosfamide (IFO) is used for treating childhood solid tumors, but its use is limited by its adverse effects on kidneys. Morin may be used to prevent nephrotoxic and other side effects. We investigated the underlying mechanisms of the protective effects of morin on IFO induced nephrotoxicity. We used 35 male rats divided into five groups of seven: control group, morin group, IFO group, 100 mg/kg morin + IFO group and 200 mg/kg morin + IFO group. We measured kidney tissue oxidant, antioxidant and inflammatory parameters using ELISA, and apoptosis was evaluated using immunohistochemistry and real time PCR. Serum urea, creatinine and kidney injury molecule-1 (KIM-1) levels were increased by IFO treatment; elevated levels were decreased significantly by treatment with both 100 and 200 mg/kg morin. Morin treatment also decreased oxidative stress and lipid oxidation in IFO treated rats. The ameliorative effect of morin on inflammatory response was due to reduced levels of NF-κB and TNF-α. Morin also reduced NF-κB/p53 levels by increasing Bcl-2 expression in IFO treated kidneys. Morin may prevent IFO induced nephrotoxicity via the NF-κB/p53 and Bcl-2 signaling pathways.

Abstract
Propolis, a product of the honey bee, has been used in traditional medicine for many years. A hydrophobic bioactive polyphenolic ester, caffeic acid phenethyl ester (CAPE), is one of the most extensively investigated active components of propolis. Several studies have indicated that CAPE has a broad spectrum of pharmacological activities as anti-oxidant, anti-inflammatory, anti-viral, anti-fungal, anti-proliferative, and anti-neoplastic properties. This review largely describes CAPE neuroprotective effects in many different conditions and summarizes its molecular mechanisms of action. CAPE was found to have a neuroprotective effect on different neurodegenerative disorders. At the basis of these effects, CAPE has the ability to protect neurons from several underlying causes of various human neurologic diseases, such as oxidative stress, apoptosis dysregulation, and brain inflammation. CAPE can also protect the nervous system from some diseases which negatively affect it, such as diabetes, septic shock, and hepatic encephalopathy, while numerous studies have demonstrated the neuroprotective effects of CAPE against adverse reactions induced by different neurotoxic substances. The potential role of CAPE in protecting the central nervous system (CNS) from secondary injury following various CNS ischemic conditions and CAPE anti-cancer activity in CNS is also reviewed. The structure–activity relationship of CAPE synthetic derivatives is discussed as well.

Abstract
Morin is a flavonoid and broadly found in white berry and cranberry branch. Ifosfamide (IFOS) is known as an anticancer and cytotoxic drug especially on the liver. This study aimed to explore the potential protective effects of Morin against IFOS-induced liver toxicity in rats. The model group of rats received a single injection of IFOS (500 mg/kg; i.p.) at day 2, whereas the protective groups of rats were given two different doses of Morin (100 and 200 mg/kg; given by gavage) at days 1 and 2. All animals were then culled 24 h post-IFOS injection. We observed that IFOS caused liver injury, oxidative stress, inflammation, DNA damage, and apoptosis. However, Morin decreased the levels of aspartate aminotransferase (AST), alkaline phosphatase (ALP), alanine aminotransferase (ALT) (p < 0.05). While Morin contributed to the recovery of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione (GSH) levels, Morin decreased the levels of malondialdehyde (MDA) induced by IFOS in the liver (p < 0.05). Besides, the levels of nuclear factor kappa B (NF-κB), tumor necrosis factor-α (TNF-α), and P53 measured by ELISA test were reduced via Morin administration (p < 0.05). Lastly, the mRNA transcript levels of Bax, Apaf-1, Bcl-2, Bcl-xL, and inducible nitric oxide synthase (iNOS) determined by RT-PCR were down-regulated in the Morin groups (p < 0.05). These results indicate that Morin plays a protective role by reducing oxidative stress, inflammation, and apoptosis in the IFOS-induced liver injury in rats.

Abstract
This review summarizes the adverse effects on the central and/or peripheral nervous systems that may occur in response to antineoplastic drugs. In particular, we describe the neurotoxic side effects of the most commonly used drugs, such as platinum compounds, doxorubicin, ifosfamide, 5-fluorouracil, vinca alkaloids, taxanes, methotrexate, bortezomib and thalidomide. Neurotoxicity may result from direct action of compounds on the nervous system or from metabolic alterations produced indirectly by these drugs, and either the central nervous system or the peripheral nervous system, or both, may be affected. The incidence and severity of neurotoxicity are principally related to the dose, to the duration of treatment, and to the dose intensity, though other factors, such as age, concurrent pathologies, and genetic predisposition may enhance the occurrence of side effects. To avoid or reduce the onset and severity of these neurotoxic effects, the use of neuroprotective compounds and/or strategies may be helpful, thereby enhancing the therapeutic effectiveness of antineoplastic drug.

Abstract
Ifosfamide (IFA), a commonly used chemotherapeutic drug, has been frequently associated with encephalopathy and central nervous system toxicity. The present study aims to investigate whether morin could protect against acute IFA-induced neurotoxicity. Morin was administered to male rats once daily for 2 consecutive days at doses of 100 and 200 mg/kg body weight (BW) orally. IFA (500 mg/kg BW; i.p.) was administered on second day. The results showed that morin markedly inhibited the production of acetylcholinesterase (AChE), butrylcholinesterase (BChE), carbonic anhydrase (CA), glial fibrillary acidic protein (GFAP), brain-derived neurotrophic factor (BDNF) and nuclear factor erythroid 2-related factor 2 (Nrf-2) induced by IFA. Morin ameliorated IFA-induced lipid peroxidation, glutathione (GSH) depletion, and decrease antioxidant enzyme activities, catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx). Histopathological changes and immunohistochemical expressions of c-Jun N-terminal kinase (JNK) and c-Fos in the IFA-induced brain tissues were decreased after administration of morin. Furthermore, morin was able to down regulate the levels of inflammatory and apoptotic markers such as nuclear factor kappa B (NF-κB), neuronal nitric oxide synthase (nNOS), tumor necrosis factor-α (TNF-α), p53, cysteine aspartate specific protease-3 (caspase-3) and B-cell lymphoma-2 (Bcl-2). Taken together, our results demonstrated that morin elicited a typical chemoprotective effect on IFA-induced acute neurotoxicity.

Abstract
Ifosfamide is an alkylating chemotherapeutic agent that exhibits activity against a wide range of tumors. Exposure to such agent just prior to mating (preconception period) may have adverse effects on developing embryos. I investigated the rate of apoptosis and the histological changes in both placenta and developing fetal tissues after exposure to ifosfamide of young female rats before mating. I clarified the roles of the drug and the placenta in causing fetal developmental toxicity. Rats were divided into four groups: (1) untreated controls, (2) rats administered saline, (3 and 4) rats administered 25 mg/kg and 50 mg/kg ifosfamide, respectively. After treatment of females with ifosfamide, the treated females were allowed to mate with normal untreated males. All pregnant animals were sacrificed on day 18 of gestation. Treatment with high doses of ifosfamide caused small placentas, fewer viable fetuses, greater post-implantation losses and more resorbed fetuses. Reduced progesterone and increased prolactin levels also were found. Immunohistochemical staining, the TUNEL technique and histological studies showed increased apoptotic cells and many histological changes in the placenta, and in fetal brain, liver and kidney tissues. Ifosfamide treatment increased apoptosis and caused hypoplasia of placental basal and labyrinth zones, which resulted in pathological changes in developing fetal tissue.

Abstract
The present study was conducted to investigate whether caffeic acid phenethyl ester (CAPE), an active component of propolis extract, has a protective effect on amphotericin B induced nephrotoxicity in rat models. Male Wistar-Albino rats were randomly divided into four groups: (I) control group (n = 10), (II) CAPE group (n = 9) which received 10 μmol/kg CAPE intraperitoneally (i.p.), (III) amphotericin B group (n = 7) which received one dose of 50 mg/kg amphotericin B, and (IV) amphotericin B plus CAPE group (n = 7) which received 10 μmol/kg CAPE i.p. and one dose of 50 mg/kg amphotericin B. The left kidney was evaluated histopathologically for nephrotoxicity. Levels of malondialdehyde (MDA), nitric oxide (NO), enzyme activities including catalase (CAT), and superoxide dismutase (SOD) were measured in the right kidney. Histopathological damage was prominent in the amphotericin B group compared to controls, and the severity of damage was lowered by CAPE administration. The activity of SOD, MDA, and NO levels increased and catalase activity decreased in the amphotericin B group compared to the control group (P = 0.0001, P = 0.003, P = 0.0001, and P = 0.0001, resp.). Amphotericin B plus CAPE treatment caused a significant decrease in MDA, NO levels, and SOD activity (P = 0.04, P = 0.02, and P = 0.0001, resp.) and caused an increase in CAT activity compared with amphotericin B treatment alone (P = 0.005). CAPE treatment seems to be an effective adjuvant agent for the prevention of amphotericin B nephrotoxicity in rat models.
