2-Mercaptobenzothiazole

2-Mercaptobenzothiazole (CAS No.: 149-30-4) is an organosulfur compound widely used in biomedical research and drug development due to its diverse biological activities and complex interactions with cellular pathways. As an activator of the aryl hydrocarbon receptor (AhR), this compound affects transcriptional activity by altering the conformation of the AhR ligand-binding domain and regulates the expression of target genes such as CYP1A1 and CYP1B1. In thyroid hormone synthesis, 2-Mercaptobenzothiazole shows inhibitory activity against thyroid peroxidase, with a half-maximal inhibitory concentration in the low micromolar range, and causes significant histological changes such as follicular cell hypertrophy in Xenopus laevis tadpoles. In addition, this compound can also impede the norepinephrine synthesis pathway in cardiomyocytes, completely blocking the conversion of dopamine to norepinephrine. It also exacerbates chromosomal aberrations and sister chromatid exchanges in Chinese hamster ovary cells and increases carcinogenic potential in experimental rat models. Therefore, 2-Mercaptobenzothiazole serves as a crucial reference molecule in studies of cell signaling pathways, genotoxicity testing, and receptor-ligand interactions, ensuring its importance in drug screening and mechanistic research. Although specific application concentrations vary depending on experimental objectives and design, its adaptability across multiple research platforms remains significant.
