Immunomodulators

Cyclo(Gly-L-Pro)
Catalog No: CFN96160

Cyclo(Gly-(L)-Pro) shows immunostimulatory properties. Cyclo(Gly-l-Pro) exhibits potent inhibition of TNF-α release with the IC50 values of 4.5 ug/mL, respectively, it also exhibits significant diminution of IL-1β and IL-6 mRNA-expression levels and NO production.
Soyasaponin Ab
Catalog No: CFN90773

Soyasaponin Ab may represent a viable candidate for effective vaccine adjuvant, TLR4 receptor dependent pathway may be involved in immune stimulatory effects of soyasaponin Ab. Soyasaponin Ab has anti-inflammatory effects, it can inhibit colon shortening, myeloperoxidase activity, the expression of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS), and activation of the transcription factor nuclear factor-κB (NF-κB); soyasaponin Ab (1, 2, 5, and 10 μM) can inhibit the production of NO (IC50 = 1.6 ± 0.1 uM) and prosta. Soyasaponin Aa and Ab can markedly inhibit adipocyte differentiation and expression of various adipogenic marker genes through the downregulation of the adipogenesis-related transcription factors PPARγ and C/EBPα in 3T3-L1 adipocytes. They also can prevent scopolamine-induced memory impairment in mice without the inhibition of acetylcholinesterase, exhibit memory-enhancing effects.
Platycoside E
Catalog No: CFN90786

Platycoside E can significantly promote the production of the sera ovalbumin (OVA)-specific IgG2a and IgG2b antibody in the OVA-immunized mice.
Purpureaside C
Catalog No: CFN93410

Purpureaside C has significant proinflammatory, antimicrobial and immunomodulating effects.
Platycodin D2
Catalog No: CFN93260

Platycodin D2 , a less hemolytic saponin, can improve specific cellular and humoral responses to hepatitis B surface antigen in mice, it could be safely used as adjuvant eliciting Th1 and Th2 immune responses. Polygalacin D2 has anti-cancer activity, it exhibits significant inhibition on the proliferation of five kinds of cultured human tumor cell lines.
