a-keto-r-methylthiobutyric acid

3-hydroxybutyric acid is involved in the synthesis and degradation of ketone bodies. Like the other ketone bodies (acetoacetate and acetone), levels of beta-hydroxybutyrate are raised in the blood and urine in ketosis. Beta-hydroxybutyrate is a typical pa

(R)-5-Oxopyrrolidine-2-carboxylic acid (D-Pyroglutamic acid) is a cyclic derivative of glutamic acid, physiologically present in mammalian tissues. It has been shown that PCA releases GABA from the cerebral cortex and displays anti-anxiety effects in a simple approach-avoidance conflict situation in the rat. In clinical pharmacology experiments, PCA significantly shortens the plasma half-life of ethanol during acute intoxication.

3-Acetyl-11-keto-ursolic acid (Compound 18), a triterpenoid derived from Eriobotrya japonica leaves, exhibits 11B-hydroxysteroid dehydrogenase 1 (11b-HSD1) inhibitory activity and holds potential for anti-diabetes 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].

(R)-pyrrolidine-2-carboxylic acid (D-Proline) is an isomer of the naturally occurring amino acid, L-Proline. D-amino acids have been found in relatively high abundance in human plasma and saliva. These amino acids may be of bacterial origin, but there is also evidence that they are endogenously produced through amino acid racemase activity.

Ganoderic acid R, exhibiting notable anticancer properties, effectively hampers tumor growth through apoptosis induction in both multidrug resistance (MDR) tumor cell line (KB-A-1/Dox) and sensitive tumor cell line (KB-A-1), demonstrating significant cytotoxicity.

(R)-3-Hydroxybutanoic acid sodium is a natural product for research related to life sciences and the catalog number is T67002.

(R)-(-)-Gossypol acetic acid (AT101 acetate) , the R-(-) enantiomer of Gossypol acetic acid, binds with Bcl-2, Bcl-xL and Mcl-1 with Ki of 0.32 μM, 0.48 μM and 0.18 μM; does not inhibit BIR3 domain and BID. Phase 2.

(R)-Leucic acid is an metabolite of amino acid.

7-keto-deoxycholic acid is converted from Lactobacillus and Bifidobacterium with specific condition and from cholic acid in vitro.

11-Keto-beta-boswellic acid, a novel Nrf2 activator, and a selective 5-lipoxygenase (5-LOX) inhibitor; it exerts dose dependent cardioprotective effect manifested by dose-dependent reduction in serum lactate dehydrogenase
