Tomatine is a glycoalkaloid, found in the tomato plant (Lycopersicon esculentum Mill.). Tomatine elicits neurotoxicity in RIP1 kinase and caspase-independent manner. Tomatine promotes the upregulation of nuclear apoptosis inducing factor (AIF) in neuroblastoma cells. Tomatine also inhibits 20S proteasome activity.

24(S)-Hydroxycholesterol (24S-OHC), the major brain cholesterol metabolite, plays an important role to maintain homeostasis of cholesterol in the brain. 24(S)-Hydroxycholesterol (24S-OHC) is one of the most efficient endogenous LXR agonist known and is present in the brain and in the circulation at relatively high levels. 24(S)-Hydroxycholesterol (24S-OHC) is a very potent, direct, and selective positive allosteric modulator of NMDARs with a mechanism that does not overlapthat of other allosteric modulators.

Ursodeoxycholic acid (Ursodeoxycholate) sodium is a secondary bile acid issued from the transformation of (cheno)deoxycholic acid by intestinal bacteria, acting as a key regulator of the intestinal barrier integrity and essential for lipid metabolism. Ursodeoxycholic acid sodium acts as signaling molecule, exerting its effects by interacting with bile acid activated receptors, including G-protein coupled bile acid receptor 5 (TGR5, GPCR19) and the farnesoid X receptor (FXR). Ursodeoxycholic acid sodium can be used for the research of a variety of hepatic and gastrointestinal diseases. Orally active.

Cortodoxone (11-Deoxycortisol; cortexolone) is a glucocorticoid steroid hormone and also is a glucocorticoid antagonist. Cortodoxone increases tryptophan oxygenase (TO) activity and induces the secretion of corticosterone. Cortodoxone regulates T cell proliferation and activation.

Allolithocholic acid is an orally active metabolite of Lithocholic acid (HY-B0172). Allolithocholic acid is a dual GPBAR1 agonist (EC₅₀ = 2.7 μM) and RORγt inverse agonist (IC₅₀ = 3.4 μM). Allolithocholic acid modulates immune and metabolic pathways, regulates immune cell polarization, prevents M1 macrophage and Th17 CD4 cell polarization. Allolithocholic acid improves insulin sensitivity, reduces liver lipid accumulation, reverses liver immunological, inflammatory and metabolic signaling dysregulation, restores bile acid homeostasis, adipose tissue histopathology/function, and intestinal microbiota composition, modulates intestinal immunity. Allolithocholic acid can be used for the researches of cancer, inflammayion, immunology and metabolic disease.

Desmosterol is a cholesterol-like molecule. In the Bloch pathway of cholesterol biosynthesis, Desmosterol is a direct precursor of cholesterol. As an endogenous metabolite, Desmosterol is used to study cholesterol metabolism . Desmosterol is an LXR activator and SREBP inhibitor, which can suppress macrophage inflammasome activation and prevent vascular inflammation and atherosclerosis. A reduction in Desmosterol promotes the production of mitochondrial reactive oxygen species (ROS) in macrophages and pyrin domain-dependent inflammasome activation of NLRP3. Desmosterol holds potential for research in inflammation, metabolism, and cardiovascular diseases .

Solamargine, a derivative from the steroidal solasodine in Solanum species, exhibits anticancer activities in numerous types of cancer. Solamargine induces non-selective cytotoxicity and P-glycoprotein inhibition. Solamargine significantly inhibits migration and invasion of HepG2 cells by down-regulating MMP-2 and MMP-9 expression and activity.

Taurocholic acid (N-Choloyltaurine) sodium salt hydrate has marked bioactive effects such as an inhibitory potential against hepatic artery ligation induced biliary damage by upregulation of VEGF-A expression. Taurocholic acid sodium salt hydrate has immunoregulation effect.
