Medchemexpress LLC Telmisartan-d7 (BIBR 277-d7) | 1794754-60-1 | 99.6% | 521.66 | 1 MG
Telmisartan-d7 (BIBR 277-d7) is a deuterium labeled Telmisartan, a potent and long-lasting antagonist of angiotensin II type 1 receptor (AT1). It selectively inhibits the binding of 125I-AngII to AT1 receptors with an IC50 of 9.2 nM. Deuteration can affect the pharmacokinetic and metabolic profiles of drugs, and stable heavy isotopes are often incorporated into drug molecules as tracers for quantitation during drug development.
- Can be used as a tracer
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
