epimer

(-)-Gallocatechin ((−)-GC) has free radical scavenging ability and moderate affinity to the human cannabinoid receptor.

D-Galactose is a naturally occurring hexose and a C-4 epimer of glucose. It can combine with glucose to form lactose and is commonly used to establish animal models of aging.

D-chiro-Inositol (D-(+)-CHIRO-INOSITOL) is an epimer of myo-inositol that is found in certain mammalian glycosylphosphatidylinositol protein anchors and inositol phosphoglycans possessing insulin-like bioactivity.

Ganorbiformin B, a lanostane triterpenoid, belongs to the same structural class as ganoderic acids, sharing the lanostane skeleton. It is the C-3 epimer of ganoderic acid T, known for its potent antimycobacterial activity against Mycobacterium tuberculosis H37Ra [1].

"S-30-Hydroxygambogic acid, a polyprenylated xanthone epimer isolated from the gamboges of Garcinia hanburyi, exhibits cytotoxicity against Human Leukemia K562 cell lines with IC50 values of 4.49 μM for K562/R and 3.61 μM for K562/S. This compound is utilized in cancer research [1]."

R-30-Hydroxygambogic acid, a polyprenylated xanthone epimer isolated from the gamboge of Garcinia hanburyi, exhibits cytotoxicity against human leukemia K562 cell lines, with IC50 values of 2.89 μM for the resistant strain (K562/R) and 1.27 μM for the sensitive strain (K562/S). This compound is utilized in cancer research [1].

3-Epideoxycholic Acid is a secondary bile acid, a microbial metabolite of Deoxycholic acid. It targets the FXR receptor on dendritic cells, reducing their immunostimulatory properties, increasing Foxp3 induction, and promoting the generation of regulatory T cells (Tregs), thereby exhibiting anti-inflammatory activity.

D-Galactose (Standard) is the standard substance of D-Galactose, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. D-Galactose is a naturally occurring hexose and a C-4 epimer of glucose. It can combine with glucose to form lactose and is commonly used to establish animal models of aging.

Tauroursocholic acid (TUCA) is the taurine-conjugated derivative of ursocholic acid and serves as the 7β-hydroxy epimer of taurocholic acid (TCA). Unlike TCA, TUCA does not inhibit HMG-CoA reductase or the cytochrome P450 (CYP) isoform CYP7A1, also known as cholesterol 7α-hydroxylase. Elevated bile levels of TUCA are observed in patients with biliary tract cancer compared to those with benign biliary conditions.

Epiprogoitrin (epi-Progoitrin) is a epimer that can be deglycosylated to epigoitrin.

10-Deacetylcephalomannin exhibits activity against PS leukemia in vivo; however, its instability leads to an equilibrium mixture with its cytotoxic C-7 epimer. Additionally, 10-Deacetylcephalomannine demonstrates growth inhibitory effects on human cancer cell lines, including cervical HeLa adenocarcinoma.
