How to use

In Vitro:

When cathepsin A (CatA) is incubated with PSI-7977 or PSI-7976 for 150 min, ~18-fold more PSI-352707 is formed when PSI-7977 is the substrate compared with PSI-7976. Moreover, the catalytic efficiency for PSI-7977 with CatA is ~30-fold higher than that for PSI-7976[1]. The genotype coverage of PSI-7977 by using GT 1b (Con1)-, 1a (H77)-, and 2a (JFH-1)-derived replicons and GT 1b chimeric replicons containing the NS5B region from the J6 GT 2a isolate and from GT 2b and GT 3a patient isolates is evaluated, PSI-7977 inhibits the replication of these replicons with similar EC50s (between 16 and 48 nM), and is especially active against the chimeric replicon containing the J6 NS5B (EC50=4.7 nM). PSI-7977 inhibits clone A (GT 1b) wild-type and S282T replicons with EC90 values of 0.42 and 7.8 μM, respectively[2]. In the clone A replicon assay, PSI-7977 produces anti-HCV activity with EC90 values 0.42 μM[3].
