Citatuzumab bogatox  (Synonyms: 泊西他组单抗; VB6-845; Anti-Human EpCAM Recombinant Antibody Fab Fragment, 17-1A)

Citatuzumab bogatox (VB6-845) is recombinant immunotoxin that composed of Fab fragment of humanized antibody targeting EpCAM and a modified cytotoxin bouganin. Citatuzumab bogatox binds to and selectively induces apoptosis in EpCAM-positive cell lines and shows good activity in EpCAM-positive human tumour xenograft models^[1][2][3].

Citatuzumab bogatox (0-100 nM; 5 days) 抑制 NIH:OVCAR-3 和 CAL-27 细胞的生长，IC₅₀ 值均为 3 nM^[1]。
Citatuzumab bogatox 内化到 EpCAM 表达细胞的细胞质中，然后释放的 Bouganin 通过核糖体失活抑制蛋白质合成，导致癌细胞凋亡^[2]。
