Medchemexpress LLC Undecanoic acid-d21 | 60658-40-4 | 207.42 | 50 MG
Undecanoic acid-d21 (Undecanoate-d21) is the deuterium labeled Undecanoic acid. Undecanoic acid is a monocarboxylic acid with antifungal property. It inhibits the production of exocellular keratinase, lipase, and the biosynthesis of several phospholipids in T. rubrum. Deuteration, the incorporation of stable heavy isotopes into drug molecules, has gained attention for its potential to affect the pharmacokinetic and metabolic profiles of drugs.
- Can be used as a tracer
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
Medchemexpress LLC Stearic acid-d7 | 951209-59-9 | 98.0% | 1 MG
Stearic acid-d7 is the deuterium labeled Stearic acid. Stearic acid is a long chain dietary saturated fatty acid which exists in many animal and vegetable fats and oils.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Deuteration has the potential to affect the pharmacokinetic and metabolic profiles of drugs.
Medchemexpress LLC L-Ascorbic acid-13C | 178101-88-7 | 99.9% | 1 MG
L-Ascorbic acid-13C is the 13C-labeled L-Ascorbic acid, an electron donor, and an endogenous antioxidant agent. It selectively inhibits Cav3.2 channels, enhances collagen deposition, and inhibits elastogenesis. This compound also exhibits anti-cancer effects by generating reactive oxygen species (ROS) and selectively damaging cancer cells.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Incorporates stable heavy isotopes for quantitation during drug development.
- Selectively inhibits Cav3.2 channels with an IC50 of 6.5 μM.
- Enhances collagen deposition and inhibits elastogenesis.
Medchemexpress LLC Citric acid-13C2 | 224054-26-6 | 194.11 | 5 MG
Citric acid-13C2 is the 13C-labeled Citric acid (HY-N1428). Citric acid acts as a natural preservative and food tartness enhancer. It induces apoptosis and cell cycle arrest at G2/M phase and S phase in HaCaT cells. It can also cause oxidative damage of the liver by decreasing antioxidative enzyme activities. Citric acid is utilized as an acidulant, emulsifier, sequestrant, and buffering agent across various industries. It is for research use only and not sold to patients.
- Can be used as a tracer
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
