179324-22-2 Usage
Description
Z-Leu-Leu-Leu-B(OH)2 (MG262) is a boronic acid-based, reversible proteasome inhibitor that is structurally similar to MG-132 but displays much higher potency (Ki = 0.03 nM versus 4 nM for MG-132).
Uses
Used in Pharmaceutical Industry:
Z-Leu-Leu-Leu-B(OH)2 (MG262) is used as a proteasome inhibitor for its high potency in inhibiting the activity of the proteasome, which is an essential cellular component involved in the degradation of proteins. This makes it a valuable tool in the development of drugs targeting various diseases, including cancer and neurodegenerative disorders.
Used in Research Applications:
Z-Leu-Leu-Leu-B(OH)2 (MG262) is used as a research tool for studying the role of the proteasome in various cellular processes and disease mechanisms. Its high potency allows for more precise and effective manipulation of proteasome activity in experimental settings, leading to a better understanding of its function and potential therapeutic applications.
Biological Activity
mg-262 (also known as z-leu-leu-leu-b(oh)2), a boronic peptide acid, is a potent proteasome inhibitor that selectively and reversibly inhibits the chymotryptic activity of the proteasome. it consists of a peptide and boronic acid moiety which are functional to proteasome inhibition. according to previous studies, mg-262 is capable of reducing the viability of nasal mucosa and polyp fibroblasts, provoking cell growth arrest, inhibiting dna replication and retinoblastoma phosphorylation, increasing expression of the cell cycle inhibitor p21 and p27, and inducing cell death via loss of mitochondrial membrane potential, caspase-3 and poly(adp-ribose) polymerase activation, induction of c-jun phosphorylation and mitogen-activated protein kinase phosphatase-1 expression.laura pujols, laura fernandez-bertolin, mireya fuentes-prado, isam alobid, jordi roca-ferrer, neus agell, joaquim mullol, and cesar picado. proteasome inhibition reduces proliferation, collagen expression, and inflammatory cytokine production in nasal mucosa and polyp fibroblasts. the journal of pharmacology and experimental therapeutics 2012; 343:184-197hilary frase, jason hudak, and irene lee. identification of the proteasome inhibitor mg262 as a potent atp-dependent inhibitor of the salmonella enteric serovar typhimurium lon protease. biochemistry 2006; 45 (27): 8264-8274

Check Digit Verification of cas no
The CAS Registry Mumber 179324-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,3,2 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 179324-22:
(8*1)+(7*7)+(6*9)+(5*3)+(4*2)+(3*4)+(2*2)+(1*2)=152
152 % 10 = 2
So 179324-22-2 is a valid CAS Registry Number.
