pyrazofurin

Pyrazofurin is a pyrimidine nucleoside analogue that potently inhibits cell proliferation and DNA synthesis by targeting UMP synthase, while also acting as a highly sensitive orotate-phosphoribosyltransferase inhibitor with IC50 values ranging from 0.06 to 0.37 μM in Hep-2, HNSCC-14B, and HNSCC-14C cell lines, supporting the use of Pyrazofurin as a mechanistic probe for nucleotide biosynthesis inhibition and antiproliferative research.
