Z-VAD(OMe)-FMK is an irreversible and cell permeable broad-spectrum Caspase Inhibitor displaying an IC50 of 5.8 nM in HepG2 cells. It has been shown to inhibit caspase-1 and caspase-3. It has also been shown to inhibit Fas-mediated apoptosis in Jurkat T cells and apoptosis in THP.1 cells induced by diverse stimuli (including cycloheximide, thapsigargin, etoposide and staurosporine). Furthermore, anti-CD95-induced hepatocyte apoptosis was prevented in a concentration-dependent manner by inhibitor Z-VAD-FMK (IC50 = 1.5 nM). Additionally, it has been shown that pretreatment of MDA-MB-231 and HL-60 cells with Z-VAD(OMe)-FMK also inhibits apoptosis.

Rated 5 out of 5 by from Good prduct, good technical service I made a purchase of z-VAD(OMe)-FMK to replicate previous findings in other AML cell lines. The current line under investigation undergoes apoptosis in response to a test compound with slower kinetics than other lines with which I had already worked. Still, I was able to show inhibition of apoptosis with 50 and 100 uM z-VAD out to 16 hours with partial effect of 50 uM at 24 hours. It seems that the higher dose is required for later time points in my AML cell lines. (I had previously seen nearly complete reversal of cell death at 10 hours using 50 uM z-VAD in other lines). Additionally, I was able to easily dissolve the compound at 100mM stock solution and it survived two freeze-thaw cycles and retained its activity. Overall, a good product. In addition, when an overnight shipment failed to arrive on a Friday due to weather and sat in a warehouse at RT over the weekend, the technical service worked with me and eventually sent a new vial for me to test. In the end, the original vial showed activity that was only slightly reduced compared to the new vial that did not have any extended time out of the freezer (as powder).

Rated 5 out of 5 by from the advantages of it it is an irreversible broad-spectrum caspase inhibitor of permeable cells, which can block apoptosis, and the effects of it is good ,but which may be harmful to the environment.
