Cat. No.	Product Name	Effect	Purity

HY-B0240

Disulfiram	Inhibitor	99.77%
Disulfiram (Tetraethylthiuram disulfide) is a specific inhibitor of aldehyde-dehydrogenase (ALDH1), used for the treatment of chronic alcoholism by producing an acute sensitivity to alcohol. Disulfiram inhibits gasdermin D (GSDMD) pore formation in liposomes and inflammasome-mediated pyroptosis and IL-1β secretion in human and mouse cells. Disulfiram, a copper ion carrier, with Cu²⁺ increases intracellular ROS levels and induces cuproptosis.

HY-Y0070

Cyanamide	Inhibitor
Cyanamide is a cell division and plant growth inhibitor, as well as an allelochemical derived from Vicia villosa. Cyanamide inhibits root growth and biomass accumulation in a dose-dependent manner by disrupting the formation of mitotic spindles and phragmoplast complexes, reducing the number of mitotic cells and blocking the cell cycle. The effects of Cyanamide are partially reversible after removal from low-concentration environments. Cyanamide is also a specific inhibitor of aldehyde dehydrogenase (ALDH). Although Cyanamide has no direct effect on tumor growth, it can significantly enhance the anti-tumor efficacy of Cyclophosphamide (HY-17420) at non-toxic doses by inhibiting the inactivation of Cyclophosphamide. Cyanamide enables Cyclophosphamide to exert equivalent therapeutic effects at lower doses, effectively inhibiting the growth of primary and metastatic tumors and prolonging the lifespan of tumor-bearing mice. Cyanamide is commonly used in studies related to ha-1 hepatoma and rls lymphosarcoma.
