|Saikosaponin b2 is a naturally occurring terpenoid that efficiently inhibits hepatitis C virus entry.[Pubmed: 25450204]|
|A vaccine against hepatitis C virus (HCV) is unavailable and cost-effective antivirals that prevent HCV infection and re-infection, such as in the transplant setting, do not exist. In a search for novel and economical prophylactic agents, we examined the antiviral activity of saikosaponins (SSa, SSb2, SSc, and SSd) from Bupleurum kaoi root (BK) as entry inhibitors against HCV infection.
METHODS AND RESULTS:
Infectious HCV culture systems were used to examine the effect of saikosaponins on the complete virus life cycle (entry, RNA replication/translation, and particle production). Antiviral activity against various HCV genotypes, clinical isolates, and infection of primary human hepatocytes were also evaluated.
BK and the saikosaponins potently inhibited HCV infection at non-cytotoxic concentrations. These natural agents targeted early steps of the viral life cycle, while leaving replication/translation, egress, and spread relatively unaffected. In particular, we identified Saikosaponin B2(SSb2) as an efficient inhibitor of early HCV entry, including neutralization of virus particles, preventing viral attachment, and inhibiting viral entry/fusion. Binding analysis, using soluble viral glycoproteins, demonstrated that SSb2 acted on HCV E2. Moreover, SSb2 inhibited infection by several genotypic strains and prevented binding of serum-derived HCV onto hepatoma cells. Finally, treatment with the compound blocked HCV infection of primary human hepatocytes.
Due to its potency, SSb2 may be of value for development as an antagonist of HCV entry and could be explored as prophylactic treatment during the course of liver transplantation.

||DMSO, Pyridine, Methanol, Ethanol, etc.
||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

|Saikosaponin b2-induced apoptosis of cultured B16 melanoma cell line through down-regulation of PKC activity.[Pubmed: 8605013]|
|Saikosaponin B2 (SSb2)was found to inhibit the proliferation of B16 melanoma cells.
METHODS AND RESULTS:
To explore this mechanism, we employed flow cytometry to determine the distribution of DNA content. The cell cycle of B16 melanoma cells was accumulated in the G1 phase followed by induction of apoptosis. This suggests that SSb2-induced proliferation inhibition is caused by G1 phase accumulation and that apoptosis induction is G1-phase-accumulation dependent. Phorbol 12-myristate 13-acetate (PMA), a protein kinase C (PKC) activator, did not interfere with the proliferation and did not induce apoptosis of B16 melanoma cells by itself. However, PMA significantly abolished these effects of SSb2 in including proliferation inhibition and apoptosis induction.
Down-regulation of the PKC activity may be involved in the effect of SSb2.
