Li, Yi-Feng;Wang, Yu-Qing;Zheng, Yi;Shi, Xue;Wang, Chong;Cheng, Yu-Lan;Zhu, Xin;Yang, Jin-Long;Liang, Xiao research published 《 Larval metamorphosis is inhibited by methimazole and propylthiouracil that reveals possible hormonal action in the mussel Mytilus coruscus》, the research content is summarized as follows. Larval metamorphosis in bivalves is a key event for the larva-to-juvenile transformation. Previously we have identified a thyroid hormone receptor (TR) gene that is crucial for larvae to acquire “competence” for the metamorphic transition in the mussel Mytilus courscus (Mc). The mechanisms of thyroid signaling in bivalves are still largely unknown. In the present study, we molecularly characterized the full-length of two iodothyronine deiodinase genes (McDx and McDy). Phylogenetic anal. revealed that deiodinases of molluscs (McDy, CgDx and CgDy) and vertebrates (D2 and D3) shared a node representing an immediate common ancestor, which resembled vertebrates D1 and might suggest that McDy acquired specialized function from vertebrates D1. Anti-thyroid compounds, methimazole (MMI) and propylthiouracil (PTU), were used to investigate their effects on larval metamorphosis and juvenile development in M. coruscus. Both MMI and PTU significantly reduced larval metamorphosis in response to the metamorphosis inducer epinephrine. MMI led to shell growth retardation in a concentration-dependent manner in juveniles of M. coruscus after 4 wk of exposure, whereas PTU had no effect on juvenile growth. It is hypothesized that exposure to MMI and PTU reduced the ability of pediveliger larvae for the metamorphic transition to respond to the inducer. The effect of MMI and PTU on larval metamorphosis and development is most likely through a hormonal signal in the mussel M. coruscus, with the implications for exploring the origins and evolution of metamorphosis.
COA of Formula: C4H6N2S, 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.
