Decitabine

Decitabine is a pyrimidine nucleoside analogue that is incorporated into DNA and inhibits DNA methyltransferase, inducing hypomethylation to reactivate silenced tumour-suppressor genes, used for myelodysplastic syndromes. Simson Pharma's Decitabine reference standard and impurities support the demanding stability-indicating QC this hypomethylating oncology agent requires.

Simson Pharma Global Ltd. (UK) and Simson Pharma Global LLC (USA) supply high-quality Decitabine 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.
