Medchemexpress LLC DC-LC3in-D5 | 2868312-73-4 | 98.6% | C19H22Cl2N2O3 | 100 MG
DC-LC3in-D5 is an autophagy inhibitor that attenuates LC3B lipidation by binding with LC3B and disrupting the LC3B-LBP2 interaction with an IC50 of 200 nM. This compound demonstrates high selectivity to LC3A/B in the proteome and exhibits potent covalent reactivity and selectivity to LC3A/B in HeLa cells. It may contribute to anti-HCV or combination research in cancer through inhibiting autophagy.
- Acts as an autophagy inhibitor by attenuating LC3B lipidation
- Binds with LC3B and disrupts the LC3B-LBP2 interaction
- Demonstrates high selectivity to LC3A/B in the proteome
- Exhibits potent covalent reactivity and selectivity to LC3A/B in HeLa cells
- Treatment of HeLa cells with 3-30 μM results in disruption of LC3B lipidation, inhibition of autophagic vesicle formation, and accumulation of p62
Medchemexpress LLC Tetrabenazine-d6 (Ro 1-9569-d6) | 1392826-25-3 | ≥99.0% | 50 MG
Tetrabenazine-d6 (Deutetrabenazine) is a deuterium-labeled Tetrabenazine (HY-B0590). It is the first deuterium approved worldwide for the research of Huntington's disease, or other hyperkinetic movement disorders. This compound is for research use only and not sold to patients. It can be used as a tracer or as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS. Deuterated compounds are expected to retain similar biochemical potency and selectivity to hydrogen analogs.
- Used as a tracer
- Used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
- Extends half-life in vivo
- Improves oral bioavailability
- Improves metabolic characteristics
- Improves drug safety
