1. What Is Bortezomib?aasraw


Bortezomib powder cas 179324-69-7, formerly known as PS-341, saled as brand “Velcade” in the market. is an anti-cancer drug and the first therapeutic proteasome inhibitor to be tested in humans. Proteasomes are cellular complexes that break down proteins. In some cancers, the proteins that normally kill cancer cells are broken down too quickly. Bortezomib powder interrupts this process and lets those proteins kill the cancer cells. The boron atom within bortezomib powder catalytically binds the active site of the 26S proteasome with high affinity and specificity, thereby resulting in cell cycle arrest and apoptosis. In normal cells, the proteasome is involved in degradation of ubiquitylated proteins that have been tagged for destruction because they are damaged or unneeded by the cell. However, in cancerous cells, proteasome activity degrades pro-apoptotic proteins such as p53 that would normally result in programmed cell death of the dysfunctional cells. Specifically, the agent inhibits nuclear factor (NF)-kappaB, a protein that is constitutively activated in some cancers, thereby interfering with NF-kappaB-mediated cell survival, tumor growth, and angiogenesis. In vivo, bortezomib powder delays tumor growth and enhances the cytotoxic effects of radiation and chemotherapy.

Bortezomib powder cas 179324-69-7 is approved in the U.S. for treating relapsed multiple myeloma and mantle cell lymphoma. In multiple myeloma, complete clinical responses have been obtained in patients with otherwise refractory or rapidly advancing disease. Bortezomib powder may also be used to treat other types of cancer as part of a research trial.
