Fiacitabine
Based on 1 Customer Validation
Fiacitabine (NSC 382097; FIAC; FOAC) is a potent and highly selective anti-herpesvirus agent. Fiacitabine acts as an inhibitor of HSV DNA polymerase, with a Ki of 0.26 μM for HSV-1 and 0.42 μM for HSV-2, respectively. Fiacitabine can be efficiently phosphorylated by thymidine kinase encoded by the virus itself to generate FIACTP, an active triphosphate metabolite. Fiacitabine is applicable to research related to herpesvirus infections.

FIACTP potently and competitively inhibits purified HSV-1 DNA polymerase (Ki = 0.26 μM), HSV-2 DNA polymerase (Ki = 0.42 μM), human leukemic leukocyte DNA polymerase α (Ki = 2.7 μM), human leukemic leukocyte DNA polymerase β (Ki = 7.9 μM), and EBV DNA polymerase (Ki = 32.2 μM) relative to dCTP, with HSV-1 DNA polymerase being the most sensitive target[1].
FIAC (2.5 μg/mL-12.5 μg/mL; 24 h) preferentially inhibits viral DNA synthesis rather than cellular DNA synthesis in HSV-1-infected Vero cells[1].
Fiacitabine (18-20 h) potently inhibits the replication of wild-type HSV-1 strains Patton, HFEM, MacIntyre, 2931 and wild-type HSV-2 strains 333, G in Vero cells[2].
Fiacitabine (78 μM; 18-20 h) inhibits the replication of thymidine kinase-negative mutant HSV-1 in Vero cells. The 90% effective dose at 18-20 h post-treatment is 78 μM, and this mutant strain is approximately 8000-fold less sensitive to it than wild-type HSV-1[2].
Fiacitabine (0.1-100 μM; 4 days) exhibits only extremely low cytotoxicity in uninfected Vero, WI-38 and NC-37 cells, with IC50 values of 5 μM, 4 μM and 10 μM respectively after 4 days of treatment[2].
Fiacitabine inhibits plaque formation of the HZV Ellen strain in WI-38 cells, with an IC50 of 0.01 μM[2].
