| Description | Bortezomib (PS-341) is a potent inhibitor of 20S proteasome with Ki of 0.6 nM. | |||||
| Targets | 20S proteasome | |||||
| IC50 | 0.6 nM (Ki) | |||||
| Cell experiment [1]: | |
|
Cell lines |
Canine malignant melanoma cell lines (CMM-1, CMM-2, ChMC, KMeC, LMeC, OMJ, OMS, OMK, and NML |
|
Preparation method |
The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months. |
|
Reaction Conditions |
72h; IC50=3.5~5.6 nM (nine kinds of cells) |
|
Applications |
Bortezomib potently suppressed the growth in 21 drugs, while other compounds had no or minimal effect on cell growth. We thus focused on bortezomib and examined its growth inhibitory properties against nine canine malignant melanoma cell lines (CMM-1, CMM-2, ChMC, KMeC, LMeC, OMJ, OMS, OMK, and NML). Bortezomib inhibited the growth of all cell lines with calculated IC50 values of 3.5~5.6 nM. |
| Animal experiment [1]: | |
|
Animal models |
Nude athymic mice |
|
Dosage form |
0.8 mg/kg; intravenous injection |
|
Applications |
The in vivo growth inhibitory activity of bortezomib against CMM-1 cells was evaluated using a xenograft mouse model. Bortezomib significantly suppressed the growth of tumours after Day 4 of treatment (P < 0.01, control vs. bortezomib). Tumours from the bortezomib-treated mice showed a significant decrease in mitotic index compared to controls (P<0.01). Similarly, the Ki67 index was significantly decreased in tumours excised from the bortezomib-treated mice when compared to controls (P < 0.01). |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

Abstract
Bortezomib, a proteasome inhibitor with anti-pancreatic cancer activity, was assessed for its role in ceramide production.
Abstract
The resistance to bortezomib, a 20S proteasome inhibitor, in MM cell lines is correlated with mitochondrial activities and could be eliminated through regulation of mitochondrial genes.
Abstract
Bortezomib, a proteasome inhibitor with modes anti-malignant glioma activity, was reviewed in terms of its effects and disadvantages.
Abstract
Instead of synergistically killing multiple myeloma cells, bortezomib inhibited the replication and spread of VSV in vitro through suppressing NF-KB activation resulting in diminished anti-tumor activity and increased VSV response. However, the combination of those two drugs exhibited synergistic effects in vivo to reduce tumor burden in two syngeneic, immunocompetent myeloma models.
Abstract
The treatment of bortezomib combined with idarubicin was well tolerated in older AML patients with the maximum tolerated dose of 1.2 mg/m(2) and 10 mg/m(2) respectively.
Bortezomib (originally codenamed PS-341) is the first therapeutic proteasome inhibitor to the tested in humans. It is approved in the U.S. for treating relapsed multiple myeloma and mantle cell lymphoma. [1] The drug is an N-protected dipeptide and can be written as Pyz-Phe-boroLeu, which stands for pyrazinoic acid, phenylalanine and Leucine with a boronic acid instead of a carboxylic acid. Peptides are written N-terminus to C-terminus, and this convention is used here even though the "C-terminus" is a boronic acid instead of a carboxylic acid. While multiple mechanisms are likely to be involved, proteasome inhibition may prevent degradation of pro-apoptotic factors, permitting activation of programmed cell death in neoplastic cells dependent upon suppression of pro-apoptotic pathways. Recently, it was found that bortezomib caused a rapid and dramatic change in the levels of intracellular peptides that are produced by the proteasome. [2] Some intracellular peptides have been shown to be biologically active, and so the effect of bortezomib on the levels of intracellular peptides may contribute to the biological and/or side effects of the drug.
A potent (Ki = 0.6 nM), specific and reversible proteasome inhibitor. It inhibits cell proliferation of H460 cells (Human non-small cell lung cancer cell lines) with an IC₅₀ of 0.1 µM.
