Abstract:

The malignance of cancers reinforces the need to find potent antineoplastic agents. In the past decades, proteasome has been witnessed as a potential target to fulfil this purpose, as evidenced by the fact that the first-in-class proteasome inhibitor Bortezomib was marketed in 2003. Marizomib (Salinosporamide A, NPI-0052), as a marine natural product, promises to be of high efficacy against multiple myeloma (MM), relapsed/refractory MM and other types of solid tumours. Compared with Bortezomib, it arguably has fewer severe side effects. Marizomib has been termed as orphan drug against multiple myeloma by US Food and Drug Administration (FDA) in 2013 and by European Medicines Agency (EMA) in 2014. As one of the second generation proteasome inhibitors (PIs), Marizomib is expected to bring about a sustained and complete therapeutic to extend cancer patients' life span. In this article, we intended to briefly review the historical developments, mechanisms, pharmacology, biosynthesis and side effects of this agent, aiming to provide concise coverage for a broad readership. In the end, we proposed our perspective for its futuristic applications.

Keywords: Anti-cancer agent, marizomib, natural product, 2nd generation proteasome inhibitor.
