L-Cysteine (L-(+)-Cysteine) is a non-essential sulfur-containing amino acid in humans. L-Cysteine is important for protein synthesis, detoxification, and diverse metabolic functions. Found in beta-keratin, the main protein in nails, skin, and hair, L-Cysteine is important in collagen production, as well as skin elasticity and texture. Also required in the manufacture of amino acid taurine, L-Cysteine is a component of the antioxidant glutathione, and plays a role in the metabolism of essential biochemicals such as coenzyme A, heparin, and biotin.

NAD+ (β-Nicotinamide Adenine Dinucleotide) is a coenzyme composed of ribosylnicotinamide 5'-diphosphate coupled to adenosine 5'-phosphate by pyrophosphate linkage. It is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH).

Ethyl gallate (gallic acid ethyl ester) obviously decreases cell proliferation in MDA-MB-231 and MCF-7 cells in a dose- and time-dependent manner, exhibits cytotoxicity in a dose-dependent manner. Ethyl gallate can inhibit the abilities of invasion of breast cancer in vitro by inhibiting the mRNA levels of MMP-9/MMP-2, phosphorylation of Akt and protein expression of NF-κB and inhibits hydrogen peroxide signaling, may represent an alternative class of vasopressors for use in septic shock. Also, Ethyl gallate suppresses proliferation and invasion in human breast cancer cells by modulating the PI3K/Akt pathway, which may contribute to inhibiting their downstream targets such as NF-κB p-65, Bcl-2/Bax, and mRNA levels of MMP-2 and MMP-9 in breast cancer cells, could be used as potential antioxidants with safe therapeutic application in cancer chemotherapy.

H-D-cis-Hyp-OH (D-allo-Hydroxyproline) belongs to the class of organic compounds known as proline and derivatives. Proline and derivatives are compounds containing proline or a derivative thereof resulting from a reaction of proline at the amino group or the carboxyl group, or from the replacement of any hydrogen of glycine by a heteroatom.

Mono-Methyl glutarate is an endogenous metabolite i with anti-inflammatory and antioxidant activity.

3-Ethoxy-3-oxopropanoic acid (Monoethyl malonic acid) belongs to the class of organic compounds known as dicarboxylic acids and derivatives. These are organic compounds containing exactly two carboxylic acid groups. 3-Ethoxy-3-oxopropanoic acid exists as a solid, soluble (in water), and a weakly acidic compound (based on its pKa). 3-Ethoxy-3-oxopropanoic acid has been primarily detected in blood.
