Salinosporamide A is a potent inhibitor of 20S proteasome with IC50 value of 1.3 nM [1].
Salinosporamide A was isolated from the crude extract of a Salinospora strain CNB-392. It showed potent anti-tumor activity with an IC50 value of 11 ng/mL in HCT-116 cells. It also exerted a mean GI50 value of less than 10 nM in the NCI’s 60 cell line-panel. Among these cell lines, Salinosporamide A showed the greatest potent efficacies in NCI-H226, SF-539, SK-MEL-28 and MDA-MB-435 cells. Salinosporamide A inhibited the purified 20S proteasome with IC50 value of 1.3 nM. It was about 35-fold more potent than the first discovered specific proteasome inhibitor, omuralide [1].
