The proteasome inhibitor PS-341 in cancer therapy.
The anticancer activity of the boronic acid dipeptide proteasome inhibitor PS-341 was examined in vitro and in vivo. PS-341 was a potent cytotoxic agent toward MCF-7 human breast carcinoma cells in culture, producing an IC90 of 0.05 microM on 24 h of exposure to the drug. In the EMT-6 tumor cell survival assay, PS-341 was equally cytotoxic administered p.o. or by i.p. injection up to a dose of ...
متن کاملDevelopment of the proteasome inhibitor PS-341.
Over the last decade, the critical role of the proteasome in cell-cycle regulation has become increasingly apparent. The proteasome, a multicatalytic protease present in all eukaryotic cells, is the primary component of the protein degradation pathway of the cell. By degrading regulatory proteins (or their inhibitors), the proteasome serves as a central conduit for many cellular regulatory sign...
متن کاملSynergistic efficacy in human ovarian cancer cells by histone deacetylase inhibitor TSA and proteasome inhibitor PS-341.
Histone deacetylase inhibitors and proteasome inhibitor are all emerging as new classes of anticancer agents. We chose TSA and PS-341 to identify whether they have a synergistic efficacy on human ovarian cancer cells. After incubated with 500 nM TSA or/and 40 nM PS-341, we found that combined groups resulted in a striking increase of apoptosis and G2/M blocking rates, no matter in A2780, cispla...

متن کاملMolecular mechanisms mediating antimyeloma activity of proteasome inhibitor PS-341.
We have recently shown that proteasome inhibitor PS-341 induces apoptosis in drug-resistant multiple myeloma (MM) cells, inhibits binding of MM cells in the bone marrow microenvironment, and inhibits cytokines mediating MM cell growth, survival, drug resistance, and migration in vitro. PS-341 also inhibits human MM cell growth and prolongs survival in a SCID mouse model. Importantly, PS-341 has...
