PSI-7977 is a Nucleotide Inhibitor of Hepatitis C Virus [2]
Hepatitis C virus (HCV) is a disease of liver cirrhosis and development of cancer in liver (hepatocellular carcinoma).
Results from studies using GT 1a (H77)-, 1b (Con1)-, and 2a (JFH-1)-derived replicons and chimeric replicons with the NS5B region fromGT 2a (J6), 2b, and 3a clearly showed that PSI-7977 is a potent HCV inhibitor across NS5B proteins from different isolates. PSI-7977 inhibited the enzymatic activity of NS5B polymerase from GTs 1 to 4 with similar 50% inhibitory concentrations [1]. PSI-7977 is a potent HCV inhibitor with broad genotype coverage. Cross-resistance and selection studies showed that S282T is likely the amino acid change that will be selected by PSI-7977 across various genotypes and subtypes. JFH-1 is a highly unique strain capable of efficient replication and infection, and this particular isolate appeared to require additional amino acid changes together with S282T to reduce the activity of PSI-7977.

| Cell experiment: [1] | |
|
Cell lines |
Non-infected Huh7.5.1 cells and JFH-1-infected Huh7.5.1 cells |
|
Preparation method |
The solubility of this compound in DMSO is >183mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months. |
|
Reaction Conditions |
24 hours |
|
Applications |
PSI-7977 prevented PKR activation/ phosphory-lation in infected cells (5-6-fold decrease) and had no effect on the expression of inactive/non-phosphorylated PKR. It had no effect on the IFN-induced expression of non-phosphorylated and phosphorylated STAT1. |
| Animal experiment: [2] | |
|
Animal models |
TK-NOG mice with non-humanized (control) or humanized livers |
|
Dosage form |
Oral administration, 44 or 440 mg/kg/d, for 14 days |
|
Applications |
The average plasma ALT levels in mice with humanized livers in the 440- and 44-mg/kg/d treatment groups were below the upper limit of normal, and were not significantly different from those measured in vehicle-treated mice with humanized livers. The plasma lactate levels were also not elevated in or control mice or mice with humanized livers receiving either dose of PSI-7977. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
