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.
