2%DMSO 30%PEG300 2%Tween80 66%ddH2O
3.0mg/ml Taking the 1 mL working solution as an example, add 20 μL of 150 mg/ml clarified DMSO stock solution to 300 μL of PEG300, mix evenly to clarify it; add 20 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 660 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Triptolide is a diterpene triepoxide, immunosuppresive agent extracted from the Chinese herb Tripterygium wilfordii. It functions as a NF-κB inhibitor with dual actions by disruption of p65/CBP interaction and by reduction of p65 protein. Triptolide (PG490) abrogates the transactivation function of heat shock transcription factor 1 (HSF1). Triptolide inhibits MDM2 and induces apoptosis through a p53-independent pathway.
Targets
NF-κB [1] HSF1 [1] MDM2 [1]
In vitro Triptolide is a diterpene triepoxide with potent immunosuppressive and antiinflammatory properties. Triptolide is shown to inhibit the expression of IL-2 in activated T cells at the level of purine-box/nuclear factor and NF-κB mediated transcription activation. [1] Triptolide inhibits the proliferation and colony formation of tumor cells at extremely low concentrations (2–10 ng/mL). Triptolide has an inhibitory activity on breast, stomach and leukemia cell line HL-60 cells. Triptolide induces apoptosis in tumor cells by blocking NF-κB activation and sensitizing tumor cells for TNF-&alpha induced programmed cell death. [2]
In vivo Triptolide synergizes with cyclosporin A in promoting graft survival in animal models and in suppression of graft versus host disease in allogeneic bone marrow transplants. In addition, it induces apoptosis in tumor cells and potentiates tumor necrosis factor (TNF-α) induction of apoptosis in part through the suppression of c-IAP2 and c-IAP1 induction. [1] [3] Triptolide treatment for 2–3 weeks inhibits the growth of xenografts formed by four different tumor cell lines (B16 melanoma, MDA-435 breast cancer, TSU bladder cancer, and MGC80-3 gastric carcinoma), indicating that TPL has a broad spectrum of activity against tumors that contain both wild-type and mutant forms of p53. In addition, Triptolide inhibits experimental metastasis of B16F10 cells to the lungs and spleens of mice. [2] Triptolide has in vitro and in vivo activities against mouse models of polycystic kidney disease. [4] LD50: Mice 0.83mg/kg (i.v.). [5]
