zvad(ome)fmk

Z-VAD(OMe)-FMK 是一种具有不可逆特性的pan-caspase抑制剂。Z-VAD(OMe)-FMK 还是泛素 C 端水解酶 L1 (UCHL1) 的抑制剂，它通过靶向 UCHL1 活性位点进行不可逆修饰。

Z-LE(OMe)TD(OMe)-FMK 是一种选择性的 caspase-8抑制剂，可以抑制细胞凋亡。

Z-VAE(OMe)-fmk is a cell-permeable and irreversible UCHL1 inhibitor. The inhibitor approaches the active-site cleft from the opposite side of the crossover loop as compared to the direction of approach of ubiquitin's C-terminal tail, thereby occupying the P1' (leaving group) site, a binding site perhaps used by the unknown C-terminal extension of ubiquitin in the actual in vivo substrate(s) of UCHL1.
