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.

Ophiopogonin D is a steroidal glycoside, which is a secondary metabolite sourced from the plant Ophiopogon japonicus. This compound is characterized by its presence in the roots, commonly referred to as radix Ophiopogonis, and is part of the broader group of ophiopogonins. Its mode of action primarily involves exerting anti-inflammatory and antioxidant effects. Ophiopogonin D has been shown to modulate signaling pathways that influence cellular oxidative stress and inflammatory responses, which are key in various pathological conditions.

Pregnanediol 3α-O-β-D-glucuronide is a steroid conjugate, which is primarily a urinary metabolite derived from the catabolism of progesterone. It represents an important biomarker in endocrinological studies with direct relevance to reproductive biology. The compound originates in the body during the breakdown of progesterone, where it is conjugated with glucuronic acid to increase its solubility for renal excretion. This transformation allows for convenient and non-invasive monitoring of progesterone levels in clinical and research settings.

**Azedarachol** is a botanical compound, which is a natural product derived from the neem tree (Azadirachta indica). This compound is known for its role as a bioactive agent, working through mechanisms that involve disrupting insect endocrine systems and acting as an antifeedant. Azedarachol's mode of action is primarily through its interference with hormonal balance within target organisms, which can lead to decreased feeding, stunted growth, and interrupted reproduction, making it an area of interest for pest control research.

Formononetin-7-O-gentiobioside is an isoflavonoid glycoside, which is a type of naturally occurring compound often found in plants, specifically in the Fabaceae family. This compound is primarily sourced from various legumes and has been studied for its potential bioactive properties due to its unique chemical structure. The mode of action of formononetin-7-O-gentiobioside involves its interaction with biological pathways, where it may exhibit antioxidant, anti-inflammatory, or estrogen-like activities, similar to other isoflavonoids. These interactions are significant in modulating cellular pathways that can contribute to various physiological effects.

DHED is a neuroactive steroid precursor, specifically a bioprecursor prodrug of estradiol, which is derived from chemical synthesis pathways. It is unique in its targeted mode of action, as it selectively converts to the active hormone estradiol within the brain via enzymatic processes that occur in situ. This specificity is facilitated by 17β-hydroxysteroid dehydrogenase type 1, which catalyzes the conversion of DHED to estradiol exclusively in the brain, minimizing peripheral estrogenic effects.

3,9-Di-O-methylcoumestrol is a synthetic coumestan derivative, which is primarily derived or synthesized from various plant sources that produce isoflavonoids and related compounds. As a type of phytoestrogen, it exhibits selective estrogen receptor modulating activity, interacting with estrogen receptors in a manner similar to endogenous hormones but with distinctive affinity and specificity. This mode of action suggests it could influence estrogen-responsive pathways, making it of particular interest in fields like endocrinology and pharmacology.
