Resiniferatoxin ([3H]resiniferatoxin) inhibits the production of Th1 cytokines, contributing to the defense against T. spiralis infection, and can be used in studies about the modulator of the immune response.

1. Telocinobufagin (Telobufotoxin) is the major endogenous digitalis-like factor. 2. Telocinobufagin significantly decreases the bacterial burdens in the spleen and prolongs the survival time of FIST-immunized mice challenged with live S. typhimurium. 3. Telocinobufagin has immunomodulatory activity, can enhance a Th1 immune response to control intracellular infections, could be developed as a novel immunotherapeutic agent to treat cancer and other immune-mediated diseases.

Ethyl Caffeate (ETHYL 3,4-DIHYDROXYCINNAMATE) suppressed the differentiation of naive CD4+ T cells into Th1 in vitro. Furthermore, Ethyl Caffeate intensely blocked the transcriptional expression in interferon-γ-related signaling, including IFN-γ, T-bet, STAT1, and STAT4.

Physalin H is an Hh signaling inhibitor blocks GLI1-DNA-complex formation, it also strong quinone reductase induction activity with IR (Induction ratio, QR induction activity) value of 3.74±0.02. Physalin H shows immunosuppressive effects on T cells both

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 e

QS-21, an immunostimulatory saponin, is a potent vaccine adjuvant that stimulates both Th2 humoral and Th1 cell-mediated immune responses by interacting with antigen presenting cells (APCs) and T cells. Furthermore, QS-21 activates the NLRP3 inflammasome, leading to the release of cytokines IL-1β and IL-18, dependent on caspase-1.
