antithyroid

Methylthiouracil (NSC-193526) 是一种抗甲状腺剂。它抑制TNF-α和IL-6的产生以及NF-κB 和ERK1 2的活化。

2-Thiouracil (Deracil) 是神经型一氧化氮合酶 (nNOS) 的选择性抑制剂(Ki:20 μM)，是一种抗甲状腺化合物，可用作高度特异性的黑色素瘤探测物。

Methimazole (Thiamazole) 是抗甲状腺化合物，具有显著的肝毒性，常用于研究甲亢。

Progoitrin 是一种硫代葡萄糖苷，与受感染作物中占主导地位。它对甲状腺活性具有抑制作用。

Carbimazole (Athyromazole) 是咪唑类甲状腺拮抗试剂，在体内快速转化为 MMI 而发挥作用，在体外可转化为甲咪唑，可用于 Graves 病的研究。

1-Methyl-2-(Methylthio)iMidazole 是 Methimazole 的杂质，Methimazole 是一种硫脲类抗甲状腺药物。

Methimazole D3, a deuterium-labeled version of Methimazole, serves as an antithyroid medication for treating hyperthyroidism in both humans and animals.

DL-Goitrin 也称为 (R,S)-Goitrin，由 epigoitrin (R-Goitrin) 和告依春 (S-Goitrin) 两种异构体组成，是板蓝根的成分。

The leguminous shrub,Leucaena leucocephala(Leucaena) is wide‐spread in tropical and subtropical agricultural systems and provides a ready source of protein for livestock. However, the presence of mimosine, a non‐protein, amino acid comprising about 12% of the dry matter in growing tips ofLeucaena, is toxic to animals. Mimosine is degraded rapidly in the rumen to produce 3,4‐dihydroxypyridine (3,4‐DHP) and 2,3‐dihydroxypyridine (2,3‐DHP), both of which remain toxic to animals[1]. 3,4-DHP, as a derivative of the plant amino acid mimosine, is goitrogenic in cattle, sheep, and mice. In contrast to established antithyroid compounds, such as methimazole (MMI) and propylthiouracil (PTU), 3,4-DHP has no SH-group. 3,4-DHP with various concentrations inhibited incorporation of125I into protein in human thyroid slices. It also suppressed the activation of lymphocytes by PHA (phytohaemagglutinin) and PWM (pokeweed mitogen). Suppression with 3,4-DHP was seen at 100 and 1000 μmol L (P< 0.001 vs both PHA and PWM). Those, together with a very low murine bone marrow toxicity, probably related to the absence of an SH-group, make 3,4-DHP a potential antithyroid drug[2].
