Imidazole is a five-membered heterocyclic moiety that possesses three carbon, two nitrogen, four hydrogen atoms, and two double bonds. 60-56-0, formula is C4H6N2S, Name is 1-Methyl-1H-imidazole-2(3H)-thione. It is also known as 1, 3-diazole. It contains two nitrogen atoms, in which one nitrogen bear a hydrogen atom, and the other is called pyrrole type nitrogen. Application of C4H6N2S.
Deshayes, Samuel;Dolladille, Charles;Dumont, Anael;Martin Silva, Nicolas;Chretien, Basile;De Boysson, Hubert;Alexandre, Joachim;Aouba, Achille research published 《 A Worldwide Pharmacoepidemiologic Update on Drug-Induced Antineutrophil Cytoplasmic Antibody-Associated Vasculitis in the Era of Targeted Therapies》, the research content is summarized as follows. The literature supporting the role of a specific drug in the onset of drug-induced antineutrophil cytoplasmic antibody-associated vasculitis (AAV) mainly relies on case reports or short series and implicates old treatments. The advent of new treatments may have modified the epidemiol. of these adverse drug reactions. This study was undertaken to update the list of drugs associated with AAV by using a pharmacovigilance-based data mining approach. We collected data on adverse drug reactions reported using the Medical Dictionary for Regulatory Activities preferred term anti-neutrophil cytoplasmic antibody pos. vasculitis up to Nov. 2020 from the World Health Organization pharmacovigilance database (VigiBase). For each retrieved drug, a case-noncase anal. was performed, and disproportionate reporting was calculated by using the information component (IC). A pos. IC025 value, which is the lower end of the 95% credibility interval, was considered significant. A total of 483 deduplicated individual case safety reports of drug-induced AAV involving 15 drugs with an IC025 >0 were retrieved. Of the individuals with drug-induced AAV for whom data on sex were available (n = 371), 264 (71.2%) were women. The median age at onset of drug-induced AAV was 62 years (quartile 1 [Q1]-Q3 45-72 years), and the median time from the introduction of the suspected drug to the onset of drug-induced AAV was 9 mo (Q1-Q3 1-36 mo). Drug-induced AAV was considered serious in 472 (98.1%), and was fatal in 43 (8.9%), of 481 cases. The drugs associated with the highest disproportionate reporting were hydralazine, propylthiouracil, thiamazole, sofosbuvir, minocycline, carbimazole, mirabegron, and nintedanib. Our findings strengthen the evidence of an association of AAV with previously suspected drugs, but also identify 3 new drugs that may cause drug-induced AAV. Particular attention should be given to these drugs by prescribers and in exptl. studies.
60-56-0, Methimazole is an antithyroid compound found to have antioxidant properties. Methimazole inhibits activation of the IFN-g-induced Janus kinase (JAK)/STAT signaling pathway in FRTL-5 thyroid cells, which may account for its immunodolulatory effects. Additionally, methimazole is an inhibitor of thyroperoxidase.
Methimazole is a thiourea antithyroid agent that prevents iodine organification, thus inhibiting the synthesis of thyroxine. Antihyperthyroid.
Methimazole is an inhibitor of thyroid hormone synthesis. It is a substrate for thyroid peroxidase that traps oxidized iodide, preventing its use by thyroglobulin for thyroid hormone synthesis. Methimazole (0.4 mg/kg) inhibits the absorption of radiolabeled iodide by the thyroid gland in rats by 80.9%.3 It reduces the incidence of lymphocytic thyroiditis in the insulin-dependent type 1 diabetic BB/W rat. Methimazole has been used to induce hypothyroidism in mice. Formulations containing methimazole have been used in the treatment of hyperthyroidism.
Methimazole is a thyreostatic compound, and an antihormone, which is widely used in medicine for the treatment of hyperthyroidism.
Methimazole is a thioamide inhibitor of the enzyme thyroid peroxidase (TPO), with antithyroid activity. Upon administration, methimazole inhibits the metabolism of iodide and the iodination of tyrosine residues in the thyroid hormone precursor thyroglobulin by TPO; this prevents the synthesis of the thyroid hormones triiodothyronine (T3) and thyroxine (T4).
Methimazole is an antithyroid medication which is now considered the first line agent for medical therapy of hyperthyroidism and Graves disease. Methimazole has been linked to serum aminotransferase elevations during therapy as well as to a clinically apparent, idiosyncratic liver injury that is typically cholestatic and self-limited in course.
Methimazole, also known as tapazole or danantizol, belongs to the class of organic compounds known as imidazolethiones. These are aromatic compounds containing an imidazole ring which bears a thioketone group. Methimazole is a drug which is used for the treatment of hyperthyroidism, goiter, graves disease and psoriasis. Methimazole is soluble (in water) and a very weakly acidic compound (based on its pKa). Methimazole has been detected in multiple biofluids, such as urine and blood. Methimazole can be converted into methimazole S-oxide., Application of C4H6N2S
