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.
