Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. 60-56-0, formula is C4H6N2S, Name is 1-Methyl-1H-imidazole-2(3H)-thione. Their solubility in alcohol is lower than that in water and decreases with increasing molecular weight of the alcohols . Category: imidazoles-derivatives.
Sun, Lijing;Wu, Liguo;An, Yaqin;Zhang, Minghua;Hou, Bingjie;Liu, Hongmei research published 《 The effects of levothyroxine combined with methimazole on the clinical efficacy of hyperthyroidism treatment.》, the research content is summarized as follows. To investigate the effects of levothyroxine combined with methimazole on the clinical efficacy of hyperthyroidism treatment. A total of 102 patients with hyperthyroidism admitted to our hospital from January 2018 to June 2020 were selected and randomly assigned into the combination group (levothyroxine combined with methimazole) and the control group (methimazole treatment alone). 3 months after treatment, the two groups were compared with regard to clinical efficacy, changes in ultrasound findings, the thyroid hormones, and serum indexes and the adverse reactions rate. The combination group (98.04%) outperformed the control group (86.27%) in total effective rate, and the overall efficacy garnered the similar result. After treatment, the combination group showed advantages in thyroid hormone level, serum index level, thyroid volume, superior thyroid artery diameter, and maximum blood flow rate when compared with those of the control group (P<0.05). As for the adverse reactions rate, the combination group was superior to the control group (3.92%vs15.69%) (P<0.05). Levothyroxine combined with methimazole promotes the clinical efficacy of hyperthyroidism treating, reduces thyroid volume and the diameter of superior thyroid artery, enhances the patient’s thyroid function and serum index, with higher safety profile.
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., Category: imidazoles-derivatives
