Liao, Sha-Sha;Liu, Wei;Cao, Jing;Zhao, Zhi-Jun research published 《 Territory aggression and energy budget in food-restricted striped hamsters》, the research content is summarized as follows. Food resource availability is one of the most important factors affecting interindividual competition in a variety of animal species. However, the energy budget and territory aggression strategy of small mammals during periods of food restriction remain uncertain. In this study, metabolic rate, body temperature, territory aggression behavior, and fat deposit were measured in male striped hamster (Cricetulus barabensis) restricted by 20% of ad libitum food intake with or without supplementary methimazole. Serum thyroid hormone (tri-iodothyronine, T3 and thyroxine, T4), and cytochrome c oxidase (COX) activity in liver, brown adipose tissue, and skeletal muscle, were also measured. Attack latency, total attack times and duration, and the interval duration between attacks of resident hamsters were not significantly changed during food restriction, which was not significantly affected by supplementary methimazole. Metabolic rate and body temperature was significantly increased in food-restricted hamsters following introduction of an intruder, which was not completely blocked by supplementary methimazole. Serum T3 and T4 levels and BAT COX activity were not significantly changed following aggression, and were significantly decreased by supplementary methimazole. These findings suggest that striped hamsters increase energy expenditure for territory aggression during food restriction, and consequently lead to excessive energy depletion. Territory aggression behavior may decrease the capacity to cope with food shortage, which may be independent of thyroid hormone.
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., Safety of 1-Methyl-1H-imidazole-2(3H)-thione
