zVAD-FMK inhibited apoptosis induced by diverse stimuli. Preincubation of cells with this caspase-1 (ICE) inhibitor (50 µM) almost completely inhibited the formation of large kilobase-pair fragments of DNA, a characteristic biochemical change associated with apoptosis. Z-VAD-FMK was shown to irreversibly inhibit most types of caspases, hence it is also called pan-caspase inhibitor. For a cell-permeable analog see N-1560. Inhibitor of peptide:N-glycanase (PNGase).

Z-Val-Ala-DL-Asp-fluoromethylketone is a drug that is used for the treatment of cancer. It can be used in combination with other chemotherapeutic drugs, such as z-vad-fmk, to induce apoptosis in cancer cells. Z-Val-Ala-DL-Asp-fluoromethylketone also inhibits autophagy and neuronal death by inhibiting caspase activation, which prevents the release of proapoptotic proteins from mitochondria into the cytosol. This drug has been shown to have antiinflammatory effects on IL2 receptor signaling pathways and inhibits the production of proinflammatory cytokines by binding to IL2.

很多蛋白在细胞中非常容易被降解，或被标记，进而被选择性地破坏。但含有部分D型氨基酸的多肽则显示了很强的抵抗蛋白酶降解能力。
