Celastrol (Tripterine;Tripterin) is a proteasome inhibitor which potently and preferentially inhibits the chymotrypsin-like activity of a purified 20S proteasome with IC₅₀ of 2.5 μM. In addition, Celastrol is also an antibiotic with potent antimicrobial activity against standard and clinical methicillin-resistant Staphylococcus aureus (MRSA) strains, inducing oxidative stress and inhibiting DNA synthesis by binding to P5CDH.

Demethylzeylasteral is an orally active triterpenoid compound isolated from Tripterygium wilfordii, which has functions such as anti-inflammatory, anti-tumor, anti fertility, estrogen metabolism regulation, immune suppression, and immune system regulation ^[1][2].

Triptonide (NSC 165677) is a natural product identified in Tripterygium wilfordii Hook F.. Triptonide is a Wnt signaling inhibitor with an IC₅₀ of appropriately 0.3 nM. Triptonide has immunosuppression, anti-inflammatory, anti-fertility, neuroprotective and anti-lymphoma effects.

Pristimerin is a potent and reversible monoacylglycerol lipase (MGL) inhibitor with an IC₅₀ of 93 nM.

(20α)-29-Hydroxy-3-oxo-olean-12-en-28-oic acid (Compound 4) is a triterpenoid. (20α)-29-Hydroxy-3-oxo-olean-12-en-28-oic acid can be isolated from T. wilfordii.

Triptohypol E is a triterpenoid compound and nitric oxide production inhibitor that can be isolated from the leaves of Rhododendron dauricum L. Triptohypol E inhibits nitric oxide production in LPS-stimulated macrophages in a dose-dependent manner.

Tripterygiumine H (Compound 8) is an alkaloid found in the dried roots of Tripterygium wilfordii.

Wilforlide A is a bioactive triterpene isolated from Tripterygium wilfordii Hook f. Wilforlide A has anti-inflammatory and immune suppressive effects.

Triptohypol C, a Tripterin (HY-13067) derivative, is a potent Nur77-targeting anti-inflammatory agent with an K_d value of 0.87 μM. Triptohypol C inhibits inflammatory response by promoting the interactions of Nur77 with TRAF2 and p62/SQSTM1.

Celastrol (Standard) is the analytical standard of Celastrol. This product is intended for research and analytical applications. Celastrol (Tripterine;Tripterin) is a proteasome inhibitor which potently and preferentially inhibits the chymotrypsin-like activity of a purified 20S proteasome with IC₅₀ of 2.5 μM.

Triptophenolide (Hypolide) is a colorless crystal isolated from the ethyl acetate extract of Tripterygium wilfordii. Triptophenolide is an orally active pan‑antagonist of the androgen receptor (AR) with an IC₅₀ of 467 nM against human wild‑type AR. Triptophenolide reduces AR expression, inhibits AR nuclear translocation, downregulates prostate‑specific antigen mRNA levels, and suppresses the growth of AR‑positive prostate cancer cells. Triptophenolide shows anti-tumor effects against breast cancer by inhibiting cell proliferation and migration, inducing G1-phase arrest and apoptosis, repressing xenograft tumor growth. Triptophenolide inhibits pyroptosis, alleviates tissue inflammation, and ameliorates synovial injury. Triptophenolide can be used for the study of prostate cancer, rheumatoid arthritis and breast cancer.

7-Hydroxychromone is a Src kinase inhibitor with an IC₅₀ of <300 μM.

Wilforine is an orally active JAK-STAT pathway inhibitor with immunomodulatory effects and the ability to inhibit osteoclast fusion. Wilforine disrupts lipid raft integrity, reprograms cholesterol and glycosphingolipid metabolic pathways, regulates NF-κB and the complement system, and modulates the expression of various interleukins. Wilforine also inhibits the Wnt11/β-catenin signaling pathway and suppresses the proliferation of fibroblast-like synoviocytes. Wilforine can serve as a quality and pharmacokinetic marker for Tripterygium glycoside tablets, and can be applied to research on related diseases such as rheumatoid arthritis, inflammatory osteolysis, and SAPHO syndrome.

Triptonoterpene is a natural product that can be isolated from the roots of Tripterygium wilfordii Hook. f..

Wilforgine is a bioactive sesquiterpene alkaloid in Tripterygium wilfordii Hook. F. Wilforgine can induce microstructural and ultrastructural changes in the muscles of Mythimna separata larvae, and the sites of action are proposed to be calcium receptors or channels in the muscular system.
