Salidroside is a bioactive phenolic glycoside compound isolated from Rhodiola rosea and is a prolyl endopeptidase inhibitor. Salidroside can alleviate cachexia symptoms in a tumor cachexia mouse model by activating mTOR signaling and protect dopaminergic neurons by enhancing PINK1/Parkin-mediated mitochondrial autophagy. Salidroside can also inhibit the growth of cancer cells by regulating the CDK4-cyclin D1 pathway to block the G1 phase and/or regulating the Cdc2-cyclin B1 pathway to block the G2 phase.

Citric acid trilithium salt tetrahydrate (Lithium citrate tribasic tetrahydrate) , the active component of Lithium, is a medicine used in the therapy of psychiatric disease. It has shown the effects of signaling pathways and metabolic in the brain based on the particular disease and clinical condition model. According to the reports, Citric acid trilithium salt tetrahydrate was used as a mood stabilizer when treating bipolar mood disorders (BD) and lower the risk of self-harm in BD patient. In addition,Citric acid trilithium salt tetrahydrate has been the choice drug in the therapy of acute manic episodes.Citric acid trilithium salt tetrahydrate also could dissolve uric acid crystals in urine achieved from patients with gout. Besides,Citric acid trilithium salt tetrahydrate have some dose-dependent side-effects. The the main side-effects of Lithium Citrate is the tendency to inhibit the prostatic acid phosphatase enzyme (PAP), which result in the accumulation of PAP.

Glucosamine (Chitosamine) is a natural product. Glucosamine is used as a dietary supplement. Glucosamine has pharmacological effects on cartilage and chondrocytes in osteoarthritis when used externally. Glucosamine regulates sugar metabolism. Glucosamine reduces the activity of glucoskinase in pancreatic islet homogenate.

Hydroxycitric acid tripotassium hydrate (Potassium citrate monohydrate) is the major active ingredient of Garcinia cambogia and a derivative of citric acid, which effectively inhibits stone formation and HIF, and has antioxidation, anti-inflammation, and anti-tumor effects. It also competitively inhibits ATP citrate lyase, offering weight loss benefits.

Chloramphenicol (Chloromycetin) is a broad-spectrum antibiotic that inhibits the biosynthesis of bacterial proteins. Chloramphenicol acts primarily on the 50S subunit of the bacterial 70S ribosome and is active against peptidyltransferases, inhibiting the formation of peptide bonds.

Baicalin (Baicalein 7-O-β-D-glucuronide) is a prolyl endopeptidase inhibitor isolated from scutellaria baicalensis, with antioxidant, anti-tumor, anti-HIV properties.

Glucosamine sulfate (D-Glucosaminesulfate) was extracted from synthetic product;Store the product in sealed, cool and dry condition.

Chlorogenic acid is a natural phenol found in honeysuckle. Chlorogenic acid has a wide range of biological activities including anti-inflammatory, antioxidant, antitumor, antimicrobial, and neuroprotective.

Baicalein (5,6,7-Trihydroxyflavone) is a xanthine oxidase inhibitor.

Glucosamine hydrochloride (Chitosamine hydrochloride) is commonly used as a treatment for osteoarthritis, although its acceptance as a medical therapy varies.

Fumaric acid (2-Butenedioic acid) attenuates the eotaxin-1 expression in TNF-α-stimulated fibroblasts by suppressing p38 MAPK-dependent NF-κB signaling. Fumaric acid has recently been identified as an oncometabolite or an endogenous, cancer-causing metabolite. High levels of this organic acid can be found in tumors or biofluids surrounding tumors. Its oncogenic action appears due to its ability to inhibit prolyl hydroxylase-containing enzymes.

Juglone (Regianin) is a natural naphthoquinone found in the black walnut (J. nigra) and other plants in the Juglandaceae family. Juglone also irreversibly inhibits peptidyl-prolyl cis/trans isomerases of the parvulin family, including human Pin1, yeast Ess1/Ptf1, and E. coli parvulin (Ki = 55.9 nM). Juglone also blocks transcription by RNA polymerases I, II, and III (IC50s = 2-7 μM) and attenuates kidney fibrosis in rats treated with unilateral ureteral obstruction, both through Pin1-independent mechanisms.

β-Elemonic Acid (3-Oxotirucallenoic Acid) exhibits anti-inflammatory effects. Beta-Elemonic acid inhibits proliferation by inducing hypoploid cells and cell apoptosis, the anticancer effects of beta-Elemonic acid are related to the MAPK signaling pathway, ROS activation and glutathione depletion in human A549 lung cancer cells. Beta-Elemonic acid exhibits prolyl endopeptidase inhibitory activities.

Halofuginone specifically inhibits collagen type I gene expression and matrix metalloproteinase 2 (MMP-2) gene expression, which may result in the suppression of angiogenesis, tumor stromal cell development, and tumor cell growth. Halofuginone Hydrobromide is the hydrobromide salt of halofuginone, a semisynthetic quinazolinone alkaloid anticoccidial derived from the plant Dichroa febrifuga, with antifibrotic and potential antineoplastic activities. These effects appear to be due to halofuginone-mediated inhibition of the collagen type I and MMP-2 promoters. Collagen type I and MMP-2 play important roles in fibroproliferative diseases.
