cIAP-2 Degrader

CST626 is a PROTAC degrader targeting IAP, with DC₅₀ values of 0.7 nM, 2.4 nM and 6.2 nM against XIAP, cIAP1 and cIAP2, respectively. This compound recruits the VHL E3 ubiquitin ligase to form a heterotrimeric complex, thereby inducing ubiquitination and proteasomal degradation of the target proteins. CST626 also exhibits certain degrading activity against VHL30 and VHL19. CST626 inhibits the proliferation and induces apoptosis of various hematologic tumor cell lines, and its anti-tumor effect is further enhanced when used in combination with TNF-α. CST626 can be used in research related to multiple myeloma, acute myeloid leukemia and diffuse large B-cell lymphoma.

TD1092 is a pan-IAP degrader, degrades cIAP1, cIAP2, and XIAP. TD1092 activates Caspase 3/7, and promotes cancer cells apoptosis via IAP degradation. TD1092 inhibits TNFα mediated NF-κB pathway and reduces the phosphorylation of IKK, IkBα, p65, and p38. TD1092 can act as PROTAC, and is used for cancer research.

SM-122 is a monovalent Smac mimetic targeting cellular inhibitor of apoptosis protein (cIAP)-1/2. SM-122 can induce cIAP-1/2 degradation and weakly induce apoptosis in tumor cells. SM-122 can be used for the research of cancer, such as breast cancer.
