(r) leucic acid

(R)-Leucic acid is a metabolite of the amino 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 releases GABA from the cerebral cortex and exhibits anti-anxiety effects in a simple approach-avoidance conflict situation in rats. In clinical pharmacology experiments, it significantly shortens the plasma half-life of ethanol during acute intoxication.

(R)-pyrrolidine-2-carboxylic acid (D-Proline) is an isomer of the naturally occurring amino acid L-Proline. D-amino acids, including D-Proline, are found in relatively high abundance in human plasma and saliva, potentially originating from bacterial sources or endogenous production via amino acid racemase activity.

(S)-Leucic acid is an amino acid metabolite used as a muscle builder.

(R)-3-Hydroxybutanoic acid sodium ((R)-3-Hydroxybutyric acid) is a chiral precursor that can be used to synthesize biodegradable PHB and its copolyesters. (R)-3-Hydroxybutanoic acid sodium can be used as a nutrient in plants.

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

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].

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.
