Sirtuin Degrader

SZU-B6 is a PROTAC degrader for SIRT6 with DC₅₀ of 45 nM and 154 nM in cell SK-HEP-1 and Huh-7. SZU-B6 inhibits the proliferation of cell SK-HEP-1 with an IC₅₀ of 1.51 μM, inhibits the colony formation of SK-HEP-1 and Huh-7, induces apoptosis and arrests the cell cycle at G2/M phase in SK-HEP-1. SZU-B6 exhibits antitumor efficacy in mouse model.

Tenovin-3 is a p53 activator.

PROTAC Sirt2 Degrader-2 is a highly efficient and selective PROTAC degrader targeting SIRT2. PROTAC Sirt2 Degrader-2 demonstrates the most potent anti-proliferative activity both in vitro and in vivo. PROTAC Sirt2 Degrader-2 leads to a marked increase in H4K16Ac levels. PROTAC Sirt2 Degrader-2 significantly suppresses clonogenic formation and migration, induces cell cycle arrest, and promotes apoptosis. PROTAC Sirt2 Degrader-2 inhibits the AKT/mTOR signaling pathway by indirectly degrading SIRT2 and blocking downstream protein phosphorylation, thereby disrupting the signaling cascade and suppressing tumor development. PROTAC Sirt2 Degrader-2 can be used for the study of ovarian cancer.
