Bufalin is an active ingredient and one of the glycosides in the traditional Chinese medicine ChanSu; it is also a bufadienolide toxin originally isolated from the venom of the Chinese toad Bufo gargarizans, with potential cardiotonic and antineoplastic a

Campesterol ((24R)-5-Ergosten-3β-ol) is a plant sterol with cholesterol lowering and anticarcinogenic effects, it and other plant sterols often decrease LDL cholesterol levels overall. Campesterol has anti-inflammatory effect, it inhibits several pro-inflammatory and matrix degradation mediators typically involved in osteoarthritis- induced cartilage degradation, also sometimes used to treat some specific prostate conditions.

Brassinolide (Brassin lactone) is a plant hormone isolated from rapeseed (Brassica napus) promoting stem elongation and cell division.

Caudatin is one of the species of C-21 steroidal glycosides mainly isolated from the root of Cynanchum bungei Decne and exhibits potent anticancer activities.

7α-Hydroxy-4-cholesten-3-one is an intermediate in bile acid synthesis from cholesterol, a PXR agonist, and a biomarker for bile acid loss and diseases related to defective bile acid biosynthesis. It is also the physiological substrate for [CYP8B1].

Cholesterol (cholesteryl alcohol) is a natural product that is the major sterol in mammals and an agonist of estrogen-related receptor α (ERRα). Cholesterol is widely found in the cell membranes of animals and is also used in the synthesis of several important hormones and bile acids.

Cinobufagin (Cinobufagine) is a selective Na+ K+-ATPase inhibitor. The activity of Cinobufagin is same as ouabain.

Beta-Sitosterol (SKF 14463) has recently been shown to induce G2 M arrest, endoreduplication, and apoptosis through the Bcl-2 and PI3K Akt signaling pathways. Beta-Sitosterol (SKF 14463) , a main dietary phytosterol found in plants, may have the potential for prevention and therapy for human cancer. Although the exact mechanism of action of Beta-Sitosterol (SKF 14463) is unknown, it may be related to cholesterol metabolism or anti-inflammatory effects (via interference with prostaglandin metabolism). Beta-Sitosterol (SKF 14463) induces apoptosis and activates key caspases in MDA-MB-231 human breast cancer cells.

Fucosterol is isolated from E. stolonifera with anti-diabetic, anti-adipogenic and anti-cancer activities. It regulates adipogenesis via modulation of PPARα and C EBPα expression.

25-Hydroxycholesterol is a steroid derivative that suppresses the cleavage of sterol regulatory element binding proteins (SREBPs). It inhibits HMG-CoA reductase and so it also plays a significant role in the in vivo regulation of cholesterol biosynthesis

Timosaponin AIII (Timosaponin A3) induces autophagy in HeLa cells followed by apoptotic cell death (IC50: 10 μM). The Timosaponin AIII cellular response is mediated via inhibition of mTORC1 and induction of ER stress (IC50: 2.5 μM, BT474 cells; 6 μM, MDAMB231). The Timosaponin AIII pro-apoptotic response is selective for tumor cells over normal cells but autophagy is induced in both.

Hydrocortisone (Cortisol) is a glucocorticoid hormone secreted by the adrenocortex. Hydrocortisone agonizes the glucocorticoid receptor, which promotes proteolytic metabolism, gluconeogenesis, capillary wall stabilization, and renal calcium excretion, as well as suppressing immune and inflammatory responses.

Deoxycholic acid (Cholanoic Acid) is a bile acid formed by bacterial action from cholate. It is usually conjugated with glycine or taurine. Deoxycholic acid acts as a detergent to solubilize fats for intestinal absorption, is reabsorbed itself, and is used as a choleretic and detergent.

WITHAFERIN A is a novel class of NFkappaB inhibitors, which hold promise as novel anti-inflammatory agents for treatment of various inflammatory disorders and or cancer.

Polyphyllin D induces apoptosis via the mitochondrial apoptotic pathway as evidenced by decreased Bcl-2 expression levels, disruption of MMP and increased Bax, cytochrome C, and cleaved-caspase-3 levels. Polyphyllin D has an anti-angiogenic effect. Polyphyllin D has toxicity in human RBCs as well as its underlying mechanism for the hemolysis and eryptosis erythroptosis. Polyphyllin D has strong anticancer activity, can overcome drug resistance in R-HepG2 cells and elicit programmed cell death via mitochondrial dysfunction.

Pregnenolone monosulfate (3β-Hydroxy-5-pregnen-20-one monosulfate) is a potent nootropic steroid that positively regulates NMDA recordings and is utilized in the study of neuroticism and depression.

Daucosterol (Sitogluside) has proliferation-enhancing activity, may be involved in the IGF1-AKT pathway. Daucosterol(β-Sitosterol β-D-glucoside) has efficient and inexpensive neuroprotectant effect, to contribute to IGF1-like activity, could be potentially developed as a medicine for ischemic stroke treatment.

Estradiol (E2) is a naturally occurring steroidal sex hormone that is essential for female fertility and maintenance of secondary sexual characteristics. Estradiol upregulates IL-6 expression through estrogen receptor beta (ERβ).

Pennogenin 3-O-beta-chacotrioside, isolated from *Paris polyphylla*, exhibits anti-colorectal cancer activity by modulating autophagy through increased expression of autophagy-related proteins LC3 and Beclin-1.

7α-Hydroxycholesterol, a cholesterol oxide formed through both enzymatic and non-enzymatic oxidation, can serve as a biomarker for lipid peroxidation.
