Applications Cholesta-3,5-diene-7-one-25,26,26,26,27,27,27-d7 is a compound useful in organic synthesis.

Applications 3-Isopropenyl-2-oxo-1-benzimidazolinebutyric Acid Ethyl Ester (cas# 116199-87-2) is a compound useful in organic synthesis.

Otophylloside B is a naturally occurring triterpenoid saponin, which is a secondary metabolite derived from the roots of the plant **Ophiorrhiza pumila**. This compound is characterized by its complex glycosidic structure, featuring a unique arrangement of sugar moieties attached to its aglycone core. The mode of action of Otophylloside B involves modulation of cellular pathways, particularly influencing apoptosis and cell cycle regulation. Its structure allows interaction with specific cellular receptors, leading to potential inhibition of tumor growth and metastasis.

Formononetin-7-acetate is a naturally-derived isoflavonoid, which is a product of acetylation of formononetin, predominantly sourced from red clover and other leguminous plants. Its mode of action involves mimicking the effects of estrogens by binding to estrogen receptors, though with less potency than endogenous estrogens. This interaction may lead to modulation of various estrogen-mediated physiological processes.

Estetrol (E4) is a naturally occurring estrogen, which is synthesized by the human fetal liver. It acts as a selective estrogen receptor modulator with a unique mode of action differentially impacting various tissues. Estetrol selectively binds to estrogen receptors, thereby facilitating a range of estrogenic activities. Interestingly, it exhibits modest estrogenic effects on both the endometrium and breast tissue, reducing potential risks typically associated with hormone therapies.

Isodeoxycholic Acid, an epimer of deoxycholic acid by gut bacteria, has lower detergent activity and inhibits C. difficile germination and toxicity.

Applications epi-Glycochenodeoxycholic Acid Sodium Salt-d7 is a labelled epimer analogue of Glycochenodeoxycholic Acid Sodium Salt (G641255), which is a bile salt formed in the liver from chenodeoxycholate and glycine. It acts as a detergent to solubilize fats for absorption and is itself absorbed. It is a cholagogue and choleretic.

Asparanin B is a natural compound, which is a specialized saponin derived from the roots of asparagus plants, specifically from Asparagus officinalis. It exerts its effects through the modulation of cellular pathways, including the inhibition of cell proliferation, induction of apoptosis, and disruption of key signaling mechanisms involved in cancer development and progression. As a result, Asparanin B is being studied for its potential anticancer properties.
