protac mdm2 degrader 4

PROTAC MDM2 Degrader-4 is a compound designed using PROTAC technology to degrade MDM2. It combines a powerful MDM2 inhibitor, a linker, and the MDM2 ligand for E3 ubiquitin ligase[1].

K-Ras ligand-Linker Conjugate 4 is a chemical compound that combines a ligand for K-Ras recruiting moiety with a PROTAC linker. This linker is responsible for recruiting E3 ligases such as VHL, CRBN, MDM2, and IAP. The compound has the potential to be used in the synthesis of PROTAC K-Ras Degrader-1, a powerful degrader of K-Ras that has been shown to exhibit a degradation efficacy of ≥70% in SW1573 cells[1].

KT-253 是一种 p53 稳定剂和 MDM2 的 PROTAC 降解剂 (DC50=0.4 nM)。它可以抑制癌细胞 RS4;11 的增殖 (IC50为 0.3 nM)，导致细胞在 G2 M 期停滞，并诱导细胞凋亡 (apoptosis)。此外，KT-253 在小鼠模型中显示出显著的抗肿瘤活性。(Pink: ligand for target proteinMDM2ligand 4; Black: linker; Blue: ligand for E3 ligasecereblon)
