| Hazard Information | Back Directory | [Description]
Delanzomib is an orally bioavailable inhibitor of chymotrypsin-like proteasome activity (IC50 = 3.8 nM in isolated human erythrocytes) that only marginally inhibits tryptic and peptidyl glutamyl proteasome activity.1 Delanzomib pre-treatment (20 nM) in vitro inhibits IκBα degradation, NF-κB activation, and the expression of NF-κB-regulated genes, including IκBα, XIAP, TNF-α, IL-1β, ICAM-1, and VEGF. Delanzomib induces apoptosis in multiple myeloma cell lines and inhibits proliferation in a panel of human hematologic and solid tumor cell lines (IC50s = 5.6-34.2 nM). It reduces tumor weight in an RPMI 8226 human multiple myeloma mouse xenograft model when administered intravenously at doses ranging from 1.5-4 mg/kg twice daily and leads to complete tumor regression at a chronic oral dose of 13 mg/kg. Delanzomib reduces the serum level of circulating cytokines, prevents renal tissue damage, and increases lifespan in a mouse model of fatal lupus nephritis. 2 | [Uses]
Delanzomib is an orally active proteasome inhibitor. Delanzomib has been shown to down-modulate NF-κB, induce apoptosis, inhibit angiogenesis and M-CSF-RANKL-induced osteoclastogenesis. | [Definition]
ChEBI: Delanzomib is a C-terminal boronic acid peptide inhibitor which induces apoptosis in multiple myeloma, hematological and solid tumor cell lines. It has a role as a proteasome inhibitor, an apoptosis inducer and an antineoplastic agent. It is a threonine derivative, a phenylpyridine, a C-terminal boronic acid peptide and a secondary alcohol. It is functionally related to a L-threonine. | [in vivo]
Delanzomib (CEP-18770; 7.8-13 mg/kg; oral administration; twice a week; for 4 weeks) treatment results in a more sustained pharmacodynamic inhibition of proteasome activity in tumors relative to normal tissues, complete tumor regression of multiple myeloma (MM) xenografts and improves overall median survival in a systemic model of human MM[1]. | Animal Model: | SCID mice injected with RPMI 8226 cells[1] | | Dosage: | 7.8 mg/kg, 10 mg/kg, 13 mg/kg | | Administration: | Oral administration; twice a week; for 4 weeks | | Result: | Resulted in a more sustained pharmacodynamic inhibition of proteasome activity in tumors relative to normal tissues.
