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.

| In vitro | In head and neck cancer cell lines, specifically HEP-2, UMSCC-14B, and UMSCC-14C, Pyrazofurin exhibited potent antiproliferative activity with IC50 values ranging from 0.06 to 0.37 μM[2]. In Vero cells, Pyrazofurin displayed broad-spectrum antiviral activity against Parainfluenza 3, Measles, Vaccinia, and Herpes Simplex Virus type 2 (HSV-2) with ED50 values ranging from 2.8 to 20 μM following a 72-hour incubation [3]. |
