Structure:

Purity:

> 95% by TLC, HPLC. Structure confirmed by NMR.

Solubility:

Soluble in DMSO up to 15 mg/ml. Pellet dry compound prior to DMSO addition.

Peptide aldehydes form a covalent hemiacetal adduct with the 20S proteasome, inhibiting the chymotrypsin-like peptidase activity. These inhibitors are reversible and cell-permeable, and also inhibit the activity of calpains and cathepsins.

Use & Storage

Use:

Add from DMSO stock directly to in vitro or in vivo assay at desired concentration. Pre-incubation with compound prior to assay is recommended for maximal effect. 20S proteasome Ki = 2 μM

Storage:

Store DMSO stock at -20°C. Avoid multiple freeze/thaw cycles.
