SMILES: O=C(CC1=CC=CC(OC(F)(F)F)=C1)N2CCC3=C2C=CC(C4=CN(C5=NC=NC(N)=C45)CCCNC(CCCCCCCCCCC(N[C@H](C(N6C[C@@H](C[C@H]6C(N[C@H](C7=CC=C(C=C7)C8=C(N=CS8)C)C)=O)O)=O)C(C)(C)C)=O)=O)=C3
Biological Activity: LD4172 is a selective RIPK1 PROTAC degrader with a Ki of 4.8 nM. LD4172 induces RIPK1 protein degradation via ternary complex formation with RIPK1 and VHL E3 ligase, driving ubiquitination and proteasomal breakdown. LD4172 abrogates TNF-induced classical NF-κB signaling in TRAF2-deficient cells, impairing IκBα phosphorylation and degradation, and reducing IL-8 production. LD4172 induces apoptosis and immunogenic cell death in tumor cells, enhances tumor-infiltrating lymphocyte responses, and sensitizes tumors to anti-PD1 therapy. LD4172 acts as a chemical probe for investigating RIPK1 scaffolding functions. LD4172 can be used for the research of melanoma, colon cancer[1][2].
