(1S,2S)-Bortezomib 是 Bortezomib 的对映异构体。Bortezomib 是一种细胞渗透性、可逆性和选择性的蛋白酶体抑制剂，通过靶向苏氨酸残基有效抑制 20S 蛋白酶体 (Ki 为 0.6 nM)。Bortezomib 破坏细胞周期、诱导细胞凋亡以及抑制核因子 NF-κB。Bortezomib 是一种抗癌活性分子，也是第一种用于人类的蛋白酶体抑制剂。 (1S,2S)-Bortezomib is an enantiomer of Bortezomib. Bortezomib is a cell-permeable, reversible, and selective proteasome inhibitor, and potently inhibits 20S proteasome (Ki of 0.6 nM) by targeting a threonine residue. Bortezomib disrupts the cell cycle, induces apoptosis, and inhibits NF-κB. Bortezomib is an anti-cancer agent and the first therapeutic proteasome inhibitor to be used in humans.
