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]. |

H2O/DMSO
DMSO
| |||||||||||||||||||||||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
