Medchemexpress LLC Tylvalosin-d9 (Acetylisovaleryltylosin-d9) | 500 UG
Tylvalosin-d9 is the deuterium-labeled form of Tylvalosin, a third-generation macrolide with anti-inflammatory properties. It reduces levels of IL-8, IL-6, IL-1β, PGE2, TNF-α, and NO, and decreases inflammatory cell recruitment and activation in a mouse acute lung injury model. This compound can be used as a tracer or an internal standard for quantitative analysis.
- Reduces levels of inflammatory mediators
- Decreases inflammatory cell recruitment and activation
- Functions as a tracer for quantitative analysis
- Functions as an internal standard for techniques like NMR, GC-MS, or LC-MS
Medchemexpress LLC 16:0-18:0-16:0 TG-d5 | 944709-25-5 | 99.9% | 840.40 | 1 MG
16:0-18:0-16:0 TG-d5 is a deuterium labeled 16:0-18:0-16:0 TG. It is intended for research use only. Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, primarily as tracers for quantitation during the drug development process. Deuteration can potentially affect the pharmacokinetic and metabolic profiles of drugs. The product is a solid, white to off-white in color.
- Can be used as a tracer
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
