Isotope-Labeled Synthetic Intermediates

3-Indoleacetic acid-d₅ (Indole-3-acetic acid-d₅) is the deuterated-labeled 3-Indoleacetic acid (HY-18569). 3-Indoleacetic acid is is an IAA hormone and growth regulator that can promote plant nutritional growth through processes such as cell expansion, differentiation, morphogenesis, and organogenesis.

Sodium 2-oxopropanoate-¹³C₃ is the ¹³C-labeled Sodium 2-oxopropanoate. Sodium 2-oxopropanoate (Sodium pyruvate), a three-carbon metabolite of Glucose, is a compound produced in the glycolytic pathway. Sodium 2-oxopropanoate is a free radical scavenger that can scavenge ROS.

L-Valine-d₈ is a deuterated form of L-Valine (HY-N0717). L-Valine ((S)-Valine) is a nonlinear semiorganic material. L-Valine causes lipid peroxidation and accumulation of malondialdehyde (MDA), exhibits inhibitory activity against cyanobacteria. L-Valine inhibits multidrug-resistant bacteria through activation of PI3K/Akt signaling pathway and inhibition of arginase.

Uric acid-¹⁵N₂ is the ¹⁵N-labeled Uric acid (HY-B2130). Uric acid is an orally active oxygen free radical scavenger that helps maintain stable blood pressure and combat oxidative stress. Uric acid can scavenge ROS, such as singlet oxygen and peroxynitrite, and inhibit lipid peroxidation. Uric acid can be used as a modeling agent in research on hyperuricemia-induced hypertension models.

Urea-¹³C,¹⁵N₂ is the ¹³C and ¹⁵N labeled Urea. Urea is a powerful protein denaturant via both direct and indirect mechanisms. A potent emollient and keratolytic agent. Used as a diuretic agent. Blood urea nitrogen (BUN) has been utilized to evaluate renal function. Widely used in fertilizers as a source of nitrogen and is an important raw material for the chemical industry.

Salicylic acid-d₆ is a deuterium labeled Salicylic acid (HY-B0167). Salicylic acid inhibits cyclo-oxygenase-2 (COX-2) activity independently of transcription factor (NF-κB) activation.

3-Indoleacetic acid-d₇ (Indole-3-acetic acid-d₇) is the deuterated-labeled 3-Indoleacetic acid (HY-18569). 3-Indoleacetic acid is is an IAA hormone and growth regulator that can promote plant nutritional growth through processes such as cell expansion, differentiation, morphogenesis, and organogenesis.

SAH-d₄ is the deuterium labeled SAH. SAH (S-Adenosylhomocysteine) is an amino acid derivative and a modulartor in several metabolic pathways. It is an intermediate in the synthesis of cysteine and adenosine. SAH is an inhibitor for METTL3-METTL14 heterodimer complex (METTL3-14) with an IC₅₀ of 0.9 μM.

Glycolic acid-d₂ is the deuterium labeled Glycolic acid. Glycolic acid is an inhibitor of tyrosinase, suppressing melanin formation and lead to a lightening of skin colour.

Potassium 1H-indol-3-yl sulfate-d₅ is the deuterium labeled 3-Indoxyl Sulfate potassium. Potassium 1H-indol-3-yl sulfate is a metabolite of tryptophan, produced by intestinal microorganisms and combined with sulfate in the liver before entering the circulatory system. Potassium 1H-indol-3-yl sulfate is a potent endogenous agonist of the aryl hydrocarbon receptor (AhR) and a urinary toxin. Potassium 1H-indol-3-yl sulfate can be used for research on kidney diseases.

Dodecane-d₂₆ is the deuterium labeled Dodecane.

1,1,3,3-Tetraethoxypropane-d₂ is the deuterium labeled 1,1,3,3-Tetraethoxypropane.

4-Hydroxyphenylacetic acid-d₆ is the deuterium labeled 4-Hydroxyphenylacetic acid. 4-hydroxyphenylacetic acid, a major microbiota-derived metabolite of polyphenols, is involved in the antioxidative action. 4-hydroxyphenylacetic acid induces expression of Nrf2.

Oxalic acid-¹³C₂ is the deuterium labeled Oxalic acid, 99% (HY-Y0262). Oxalic Acid is a strong dicarboxylic acid occurring in many plants and vegetables and can be used as an analytical reagent and general reducing agent.

Pipecolic acid-d₉ is the deuterium labeled Pipecolic acid. Pipecolic acid is a metabolite of lysine and an important precursor for many useful microbial secondary metabolites. Pipecolic acid slows ferroptosis in diabetic retinopathy by inhibiting the YAP-GPX4 signaling pathway. In addition, Pipecolic acid can be used as a diagnostic marker for pyridoxine-dependent epilepsy.

Guaiacol-d₃ is the deuterium labeled Guaiacol. Guaiacol, a phenolic compound, inhibits LPS-stimulated COX-2 expression and NF-κB activation. Guaiacol has an anti-inflammatory activity.

Phenylpyruvic acid-d₅ sodium is the deuterium labeled Phenylpyruvic acid sodium.
