at-406

Xevinapant hydrochloride (AT-406 HCl) 是口服生物可利用的 Smac 模拟物，也是细胞凋亡蛋白抑制剂的拮抗剂。它在无细胞功能测定中有效拮抗 XIAP BIR3 蛋白，诱导细胞 cIAP1 蛋白的快速降解，并抑制各种人类癌细胞系中的癌细胞生长。它在诱导异种移植肿瘤细胞凋亡方面非常有效。

Xevinapant (Debio-1143) 是一种有效的 Smac 模拟物和 IAP 的拮抗剂，能够抑制 XIAP，cIAP1 和 cIAP2 蛋白，Ki 值分别为 66.4，1.9 和 5.1 nM。

Tofacitinib maleate, also known as tasocitinib, CP-690550, is a Janus kinase (JAK) inhibitor. Tofacitinib maleate modulates the signaling pathway at the point of JAKs, preventing the phosphorylation and activation of STATs. JAK enzymes transmit cytokine signaling through pairing of JAKs (e.g., JAK1 JAK3, JAK1 JAK2, JAK1 TyK2, JAK2 JAK2). Tofacitinib maleate inhibited the in vitro activities of JAK1 JAK2, JAK1 JAK3, and JAK2 JAK2 combinations with IC50 of 406, 56, and 1377 nM, respectively.
