N-Bis(2-hydroxypropyl)nitrosamine BiologicalActivity

Description	N-Bis(2-hydroxypropyl)nitrosamine is an agent with carcinogenic activity.
Related Catalog	Signaling Pathways >>Others >>OthersResearch Areas >>Cancer
In Vitro	N-Bis(2-hydroxypropyl)nitrosamine is an agent with carcinogenic activity[1].
In Vivo	N-Bis(2-hydroxypropyl)nitrosamine causes the tumors to develop in the lung, liver, and thyroid of rats at a dose of 100 ppm, in the lung, liver thyroid, esophagus, kidney, and urinary bladder of rats at a dose of 500 ppm, and in the lung, liver thyroid, esophagus, kidney, and urinary bladder of rats at both doses[1]. Bisphenol A (BPA) enhances the susceptibility to thyroid carcinoma stimulated by N-Bis(2-hydroxypropyl)nitrosamine (DHPN; 2800 mg/kg) in rats[2].
