COA 产品使用指南

2-Mercaptobenzothiazole 是芳烃受体 (AhR) 的激活剂,甲状腺激素合成的抑制剂,多巴胺 β-羟基羟化酶的抑制剂。2-Mercaptobenzothiazole 通过改变 AhR 配体结合域 (LBD) 的构象,激活 AhR 转录并上调靶基因 CYP1A1 和 CYP1B1 的 mRNA 和蛋白表达,从而促进膀胱癌细胞 (BC) 的 侵袭。 2-Mercaptobenzothiazole 抑制甲状腺过氧化物酶 (TPO) 的 IC50 为 11.5 μM,在非洲爪蟾幼虫中抑制甲状腺激素合成引起甲状腺滤泡细胞肥大等组织学反应,延缓发育变质。 2-Mercaptobenzothiazole 还增加了中国仓鼠卵巢 (CHO) 细胞中的染色体畸变和姐妹染色单体交换 (SCE) 频率,提高了 F344/N 大鼠的致癌活性。 2-Mercaptobenzothiazole 有效抑制小鼠体内去甲肾上腺素合成并完全阻断外源性多巴胺在大鼠心肌中向去甲肾上腺素的转化。

生物活性

2-Mercaptobenzothiazole is an activator of the aryl hydrocarbon receptor (AhR)[1], inhibiting thyroid hormone synthesis and dopamine beta-hydroxylase activity[2][4]. 2-Mercaptobenzothiazole promotes bladder cancer cell invasion by altering the conformation of the AhR ligand binding domain (LBD), activating AhR transcription, and upregulating the mRNA and protein expression of target genes CYP1A1 and CYP1B1[1]. 2-Mercaptobenzothiazole inhibits thyroid peroxidase (TPO) with an IC50 value of 11.5 μM, induces histological changes such as follicular cell hypertrophy in Xenopus laevis tadpoles, delaying metamorphosis[2]. 2-Mercaptobenzothiazole increases chromosomal aberrations and sister chromatid exchanges (SCEs) in Chinese hamster ovary (CHO) cells, and enhances carcinogenicity in F344/N rats[3]. 2-Mercaptobenzothiazole inhibits norepinephrine synthesis in mice and completely blocks the conversion of exogenous dopamine to norepinephrine in rat cardiomyocytes[4].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
