Mercaptopurine

Mercaptopurine (6-MP) is the active thiopurine antimetabolite generated from azathioprine, incorporated into DNA/RNA synthesis pathways to block proliferation of malignant and immune cells, used for acute lymphoblastic leukaemia and inflammatory bowel disease. Simson Pharma's Mercaptopurine reference standard and impurities support QC across both oncology and immunology applications.

Simson Pharma Global Ltd. (UK) and Simson Pharma Global LLC (USA) supply high-quality Mercaptopurine Reference Standards, pharmacopoeial reference materials, and its related impurities to pharmaceutical manufacturers, CROs, analytical laboratories, universities, and regulatory organizations worldwide. To service the Europe and America market efficiently, Simson Pharma Limited has set up Simson Pharma Global Ltd. in United Kingdom and Simson Pharma Global LLC in USA respectively.
