The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . 60-56-0, formula is C4H6N2S, Name is 1-Methyl-1H-imidazole-2(3H)-thione. In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with an increase of the alkyl chain length of the alcohols. HPLC of Formula: 60-56-0.
Iakovenko, Roman O.;Chrenko, Daniel;Kristek, Jozef;Desmedt, Eline;Zalesak, Frantisek;De Vleeschouwer, Freija;Pospisil, Jiri research published 《 Heteroaryl sulfonamide synthesis: Scope and limitations》, the research content is summarized as follows. Heteroaryl sulfonamides are important structural motifs in the medicinal and agrochem. industries. However, their synthesis often relies on the use of heteroaryl sulfonyl chlorides, which are unstable and toxic reagents. Herein, the authors report a protocol that allows direct oxidative coupling of heteroaryl thiols R1SH (R1 = pyrimidin-2-yl, pyridin-2-yl, 1,3-benzothiazol-2-yl, etc.) to primary amines R2NH2 (R2 = CH2Ph, CH(Me)CO2Me, CH(CO2Me)(CH2)2CO2Me, etc.) and Me (2S)-pyrrolidine-2-carboxylate, readily available and inexpensive commodity chems. The transformation proceeds under mild reaction conditions and yields the desired N-alkylated sulfonamides, e.g., I, in good yields. N-alkyl heteroaryl sulfonamides can be further transformed using a microwave-promoted Fukuyama-Mitsunobu reaction to give N,N-dialkyl heteroaryl sulfonamides. The developed protocols thus enable the preparation of previously difficult to prepare sulfonamides (toxic reagents, harsh conditions, and low yields) under mild conditions.
HPLC of Formula: 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., 60-56-0.
