hepatotoxic drugs

Tuberculosis (TB) is a challenging public health issue, particularly in poor and developing countries. Rifampicin (RIF) is one of the most common first-line anti-TB drugs but it is known for its adverse effects on the hepato-renal system. The present study investigated the efficacy of morin hydrate (MH) in protecting hepato-renal damage inflicted by RIF in rats. RIF (50 mg/kg), and a combination of RIF (50 mg/kg) and MH (50 mg/kg) were administered orally for 4 weeks in rats. Silymarin (50 mg/kg) was used as a positive control...

Fosfomycin is an antibiotic frequently used to treat uncomplicated urinary tract infections. It is normally well-tolerated, but there are some reports of clinically relevant liver injury. We present the case of a 73-year-old female who presented with paucisymptomatic hepatocellular acute liver injury six days after taking fosfomycin. After ruling out viral, ischemic, and autoimmune hepatitis, as well as Wilson disease and biliary disorders, she was diagnosed with drug-induced liver injury (DILI) related to fosfomycin...

Tuberculosis (TB) treatment requires a long therapeutic duration and induces adverse effects such as hepatotoxicity, causing discontinuation of treatment. Reduced adherence to TB medications elevates the risk of recurrence and the development of drug resistance. Additionally, severe cavitary TB with a high burden of Mycobacterium tuberculosis (Mtb) and inflammation-mediated tissue damage may need an extended treatment duration, resulting in a higher tendency of drug-induced toxicity. We previously reported that the administration of Lactobacillus sakei CVL-001 (L...

Doxorubicin (DOX) is widely used in cancer treatment but the dose-related toxicity of DOX on organs including the liver limit its use. Therefore, there is great interest in combining DOX with natural compounds with antioxidant properties to reduce toxicity and increase drug efficacy. Esculetin is a natural coumarin derivative with biological properties encompassing anti-inflammatory and antioxidant activities. In light of these properties, this study was meticulously crafted to investigate the potential of esculetin in preventing doxorubicin (DOX)-induced hepatotoxicity in Sprague-Dawley rats...

Due to the rise in temperature and sea level caused by climate change, the detection rate of aflatoxin B1 (AFB1) in food crops has increased dramatically, and the frequency and severity of aflatoxicosis in humans and animals are also increasing. AFB1 has strong hepatotoxicity, causing severe liver damage and even cancer. However, the mechanism of AFB1 hepatotoxicity remains unclear. By integrating network toxicology, molecular docking and in vivo experiments, this research was designed to explore the potential hepatotoxicity mechanisms of AFB1...

Acetaminophen (APAP) overdose is one of the most common causes of acute liver injury. The current standard-of-care treatment for APAP hepatotoxicity, N -acetyl- l -cysteine, is highly effective when administered early after overdose, but loses efficacy in later-presenting patients. As a result, there is interest in the identification of new treatments for APAP overdose patients. Natural products are a promising source of new treatments because many are purported to have hepatoprotective effects. In fact, a great deal of research has been done to identify natural products that can protect against APAP-induced liver injury...

BACKGROUND: In recent decades, there has been a substantial surge in the incidence of non-tuberculous Mycobacteria (NTM) infections. However, the diagnosis and management of NTM globally present significant challenges, particularly in cases involving Mycobacterium abscessus complex (MABC) infection where effective therapeutic options are limited. CASE PRESENTATION: We reported a 38-year-old female patient who was infected with MABC of skin due to "beauty needle" at a beauty salon, with mass on both cheeks, accompanied by redness, and pain, and some of them was ulcered and effused...

Alzheimer's disease (AD), is characterized by a progressive loss of cognitive abilities as well as behavioral symptoms including disorientation, trouble solving problems, personality and mood changes. Acetylcholinesterase (AChE) is a promising target for symptomatic improvement in AD due to its consistent and early cholinergic deficit. This research has investigated the potential compounds from Catunaregam spinosa as AChE inhibitors as a treatment option for AD, aiming to enhance cholinergic neurotransmission and alleviate cognitive decline...

Human liver organoids (HLOs) hold significant potential for recapitulating the architecture and function of liver tissues in vivo. However, conventional culture methods of HLOs, forming Matrigel domes in 6-/24-well plates, have technical limitations such as high cost and low throughput in organoid-based assays for predictive assessment of compounds in clinical and pharmacological lab settings. To address these issues, we have developed a unique microarray 3D bioprinting protocol of progenitor cells in biomimetic hydrogels on a pillar plate with sidewalls and slits, coupled with a clear bottom, 384-deep well plate for scale-up production of HLOs...

Diclofenac, a widely used non-steroidal anti-inflammatory drug, can cause liver damage via its metabolic activation by hepatic CYP450s and UGT2B7. Fasting can affect drug-induced liver injury by modulating the hepatic metabolism, but its influence on diclofenac hepatotoxicity is unknown. Thus, we investigated diclofenac-induced liver damage after fasting in mice, and the cellular events were examined. Male ICR mice fasted for 16 h showed the elevation of CYP3A11, but the decreases of UGT2B7, glutathione (GSH), and GSH S-transferase-μ/-π levels in the livers...

BACKGROUND: Tuberculosis preventive treatment (TPT) is a key component of tuberculosis elimination. To improve completion and reduce the burden for people and health systems, short, safe, and effective TPT regimens are needed. We aimed to compare safety and treatment completion of various doses and durations of rifampicin in people who were recommended to receive TPT. METHODS: This partially blinded, parallel-arm, non-inferiority, randomised, controlled, phase 2b trial was done at seven university-affiliated clinics in Canada, Indonesia, and Viet Nam...

Vitamin A supplements are used by many people, and the number of newly registered dietary supplements is continuously increasing. The preparations fall under food law and are not subject to the strict controls of pharmaceuticals. Risk indications and maximum quantity recommendations, e.g., from the Bundesinstitut für Risikobewertung (BfR) and the U.S. Food and Drug Administration (FDA) are not binding, which means that overdoses and potentially serious health problems can easily occur. The hepatotoxicity and teratogenicity of vitamin A are well documented, and other negative effects of high doses of vitamin A are also being discussed...

OBJECTIVE: The purpose of this study is to comparatively analyze the anticancer properties of Tetrahydrocannabinol (THC), Cannabidiol (CBD), and Tetrahydrocannabivarin (THCV) using In silico tools. METHODS: Using SwissADME and pkCSM, the physicochemical and pharmacokinetics properties of the cannabinoids were evaluated. Protox-II was utilized for the assessment of their cytotoxicity. The chemical-biological interactions of the cannabinoids were also predicted using the Way2Drug Predictive Server which comprises Acute Rat Toxicity, Adver-Pred, CLC-Pred, and Pass Target Prediction...

Nialamide is a non-selective monoamine oxidase inhibitor that was widely used as an antidepressant. However, it has been prohibited for decades in the depressive medicine market due to the adverse hepatotoxic side effects. The re-use of drugs that have been withdrawn from the market represents a promising approach for the development of novel incrementally modified drugs and, in this context, ionizing radiation can serve as a powerful tool for producing new drug candidates. The present study exposed nialamide to γ radiation at 50 kGy to obtain the novel cyclized benzylamide, nialaminosin (compound 2), along with five known compounds, 3-amino- N -benzylpropanamide (compound 3), 3-methoxy- N -benzylpropanamide (compound 4), 3-hydroxy- N -benzylpropanamide (HBPA; compound 5), N -benzylpropanamide (compound 6) and isonicotinamide (compound 7)...

BACKGROUND: Management outcomes of drug-resistant (DR) osteoarticular tuberculosis (OATB) is dismal as in pre-ATT era (1905). The studies documenting treatment outcome of DR-OATB are scarce; hence, present retrospective analysis was conducted to evaluate outcome of consecutive cases of DR-OATB. METHODS: 45 consecutive patients of suspected DR-OATB were treated from 2010 onwards. Tissue samples were submitted for AFB smear, cytology/histology, liquid culture, CBNAAT/LPA besides gram's staining and aerobic/anaerobic culture...

An enhanced, sustainable, and efficient method for synthesizing tacrine, achieving a 98% yield, has been developed by replacing volatile organic compounds with more eco-friendly solvents such as deep eutectic solvent (DESs). The optimized protocol scales easily to 3 g of substrate without yield loss and extends successfully to tacrine derivatives with reduced hepatotoxicity. Particularly notable is the synthesis of novel triazole-based derivatives, yielding 90-95%, by integrating an in situ preparation of aryl azides in DESs with N -propargyl-substituted tacrine derivatives...

Understanding the final fate of nanomaterials (NMs) in the liver is crucial for their safer application. As a representative two-dimensional (2D) soft nanomaterial, graphene oxide (GO) has shown to have high potential for applications in the biomedical field, including in biosensing, drug delivery, tissue engineering, therapeutics, etc. GO has been shown to accumulate in the liver after entering the body, and thus, understanding the GO-liver interaction will facilitate the development of safer bio-applications...

Three-dimensional liver bioprinting is an emerging technology in the field of regenerative medicine that aids in the creation of functional tissue constructs that can be used as transplantable organ substitutes. During transplantation, the bioprinted donor liver must be protected from the oxidative stress environment created by various factors during the transplantation procedure, as well as from drug-induced damage from medications taken as part of the post-surgery medication regimen following the procedure...

Microcystin-LR (MC-LR) is a secondary metabolite produced by cyanobacteria, globally renowned for its potent hepatotoxicity. However, an increasing body of research suggests that it also exhibits pronounced neurotoxicity. PP2A is a fundamental intracellular phosphatase that plays a pivotal role in cell development and survival. Although extensive research has focused on the binding of MC-LR to the C subunit of PP2A, few studies have explored the key amino acid sites that can prevent the binding of MC-LR to PP2A-C...

Post-marketing hepatotoxicity findings are more common or occur much later. NSAIDs (non-steroidal anti-inflammatory drugs) like ibuprofen are consumed in large quantities around the world. NSAIDs have a low incidence of hepatotoxicity but their wide use makes them a major contributor to drug-induced liver injury. Hepatitis is linked to systemic oxidative stress which results in cellular necrosis and fibrosis, as well as tissue lipoprotein peroxidation and glutathione depletion. Given the lack of safe and effective anti-hepatitis drugs in medicine today, natural substances appear to be a promising and safe alternative...
