In Vitro

Isothiafludine inhibits HBV DNA replication, with an IC50 of 1.33 μM[1].
Isothiafludine (8 days) shows an IC50 (50% cytotoxicity) of 50.4 μM against HepG2.2.15 cells[1].
Isothiafludine (1.25-20 μM, 48 h) also inhibits the replication of 3TC/ETV-dual-resistant and ADV-resistant HBV mutants in virus transfected Huh7 cells[1].
Isothiafludine (10-20 μM, 8 days) decreases the levels of encapsidated HBV pgRNA in HepG2.2.15 cells[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
