PYR-41 - 99%, high purity , CAS No.418805-02-4
Ubiquitin-activating enzyme (E1) inhibitor
Basic Description Synonyms 4-[4-(5-nitro-furan-2-ylmethylene)-3,5-dioxo-pyrazolidin-1-yl]-benzoic acid ethyl ester | ethyl 4-(4-((5-nitrofuran-2-yl)methylene)-3,5-dioxopyrazolidin-1-yl)benzoate | Spectrum2_001078 | ETHYL 4-{4-[(5-NITROFURAN-2-YL)METHYLIDENE]-3,5-DIOXOPYRAZOLIDIN-1- Specifications & Purity ≥99% Biochemical and Physiological Mechanisms Ubiquitin-activating enzyme (E1) inhibitor (IC 50 = 5 µM). Inhibits ubiquitination and proteasomal degradation. Additionally increases sumoylation of proteins and induces p53-mediated apoptosis. Storage Temp Store at -20°C Shipped In Ice chest + Ice pads Note Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
