Medchemexpress LLC Tipranavir-d7 | 174484-41-4 | C31H26D7F3N2O5S | 5 MG
Tipranavir-d7 is a deuterated form of Tipranavir. Tipranavir is known to inhibit the enzymatic activity and dimerization of HIV-1 protease. It demonstrates potent activity against multi-protease inhibitor (PI)-resistant HIV-1 isolates, with IC50s ranging from 66-410 nM. Additionally, Tipranavir has been shown to inhibit SARS-CoV-2 3CLpro activity.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Exerts potent activity against a wide spectrum of wild-type and multi-PI-resistant HIV-1 variants.
- Inhibits the enzymatic activity of HIV-1 protease.
- Blocks the dimerization of protease subunits.
