Antimicrob Agents Chemother 2021 Feb 22. Epub 2021 Feb 22.

Department of Microbiology and Immunology, Albert Einstein College of Medicine, Bronx, New York, USA

acetylcysteine (NAC) is most commonly used for the treatment of acetaminophen overdose and acetaminophen-induced liver injury. In patients infected with , the causative agent of tuberculosis (TB), NAC is given to treat hepatotoxicity induced by TB drugs. We had previously shown that cysteine, a derivative of NAC, potentiated the activity of isoniazid, a first-line TB drug, by preventing the emergence of INH resistance and persistence in in vitro.

Transbuccal Delivery of Isoniazid: Ex Vivo Permeability and Drug-Surfactant Interaction Studies.

AAPS PharmSciTech 2020 Oct 20;21(8):289. Epub 2020 Oct 20.

Programa de Pós-Graduação em Farmácia, Universidade Federal de Santa Catarina, Campus Universitário, Trindade, Florianópolis, SC, 88040-900, Brazil.

The oral administration of isoniazid (INH) may lead to discontinuation of tuberculosis treatment due to drug-related hepatotoxicity events, and thus, the transbuccal delivery of this drug was investigated, for the first time, as an alternative administration route. Ex vivo permeability assays were performed in Franz-type diffusion chambers, applying INH alone and in combination with sodium dodecyl sulfate (SDS) and sodium taurocholate (ST). After confirming the formation of micelle structures by dynamic light scattering analysis, UV-visible spectroscopy and zeta potential analyses were used to investigate drug-micelle interactions.

A case series of three patients presenting with isoniazid induced toxicity and N-acetyl transferase 2 gene mutation: A management conundrum for programmatic therapy of tuberculosis in India.

Indian J Tuberc 2020 Jul 20;67(3):407-410. Epub 2020 Jan 20.

Department of Medicine, LTM Medical College & LTM General Hospital, Mumbai, India.

Isoniazid is an essential drug in the management of tuberculosis but there is a high degree of variation in the Indian population's capacity to acetylate or inactivate isoniazid to the inactive metabolite acetyl isoniazid, and they can be distinctly characterized phenotypically as being either slow or rapid inactivators (the concentration of the enzyme being higher in rapid inactivators). Several mutations in the N-acetyl transference 2 (NAT2) gene account for majority of the slow acetylator genotypes in the human population (NAT2*5A, NAT2*5B, and NAT2*6A). Such individuals are at a greater risk of drug-induced adverse reactions due to reduced drug elimination, compared to those possessing the wild type allele. Read More

Naphthoquinone-based hydrazone hybrids: synthesis and potent activity against cancer cell lines.

Med Chem 2020 Aug 17. Epub 2020 Aug 17.

Graduate College of Health and Biological Sciences, Federal University of San Francisco Valley, Petrolina, PE. Brazil.

Background: Natural naphthoquinones have shown diversified biological activities including antibacterial, antifungal, antimalarial, and cytotoxic activities. However, they are also compounds with acute cytotoxicity, immunotoxicity, carcinogenesis, and cardio- and hepatotoxicity, then the modification at their redox center is an interesting strategy to overcome such harmful activity.

Objective: In this study, four novel semisynthetic hydrazones, derived from the isomers α- and β-lapachones (α and β, respectively) and coupled with the drugs hydralazine (HDZ) and isoniazid (ACIL), were prepared, evaluated by electrochemical methods and assayed for anticancer activity. Read More

Evidence of drug-induced hepatotoxicity in the Maghrebian population.

Drug Chem Toxicol 2020 Jul 26:1-5. Epub 2020 Jul 26.

Faculty of Medicine and Pharmacy, Laboratory of Chemistry-Biochemistry, Environment, Nutrition, and Health, Hassan II University, Casablanca, Morocco.

Drug-induced hepatotoxicity is one of the most challenging hepatic diseases faced nowadays due to a large number of drugs currently used in clinical practice, the enormous dietary supplements which are potentially hepatotoxic, as well as the ability to appear with different clinical symptoms and the absence of specific markers. The current research survey was conducted to investigate drug-induced hepatotoxicity and demographic characteristics of patients with liver damage in the general Maghrebian population between 1992 and 2018. To achieve this goal a questionnaire was adopted to report details on the undesirable effects of drugs and demographic characteristics of affected patients. Read More

Department of Chemical Biology and Therapeutics, St. Jude Children's Research Hospital, Memphis, TN 38105, USA.

Tuberculosis is a global health threat that affects millions of people every year, and treatment-limiting toxicity remains a considerable source of treatment failure. Recent reports have characterized the nature of -mediated hepatotoxicity and the systemic toxicity of antitubercular drugs. The antitubercular drug isoniazid plays a role in such pathologic states as acute intermittent porphyria, anemia, hepatotoxicity, hypercoagulable states (deep vein thrombosis, pulmonary embolism, or ischemic stroke), pellagra (vitamin B deficiency), peripheral neuropathy, and vitamin B deficiency.
