PROTAC Bcl2 degrader-1 is a PROTAC, which potently and selectively induces the degradation of Mcl-1 (IC50: 11.81 μM) and Bcl-2 (IC50: 4.94 μM; DC50: 3.0 μM).
PROTAC Sirt2 Degrader-1 is a SirReal-based PROTAC, acts as a Sirt2 degrader, composed of a highly potent and isotype-selective Sirt2 inhibitor, a linker, and a bona fide cereblon ligand for E3 ubiquitin ligase. PROTAC Sirt2 Degrader-1 shows an IC50 of 0.25 μM for Sirt2, with no effect on Sirt1 Sirt3 (IC50s > 100 μM)[1].
PROTAC Mcl1 degrader-1 induces the ubiquitination and proteasomal degradation of Mcl-1 by introducing the E3 ligase cereblon (CRBN)-binding ligand pomalidomide to Mcl-1 inhibitor S1-6 with μM-range affinity. PROTAC Mcl1 degrader-1, a proteolysis targeting chimera (PROTAC), is a potently and selectively Mcl-1 inhibitor with an IC50 of 0.78 μM.
9-Decyn-1-ol is an alkyl ether-based PROTAC linker suitable for synthesizing PROTACs. It serves as a conjugation agent to combine GDC-0068 and Lenalidomide, resulting in the formation of INY-03-041. INY-03-041 is a potent and highly selective pan-Akt degrader that operates through the PROTAC mechanism. It effectively inhibits Akt1, Akt2, and Akt3 with IC50 values of 2.0 nM, 6.8 nM, and 3.5 nM, respectively[1].
PROTAC CBP P300 Degrader-1 is an effective compound that degrades CBP P300 in a potent manner. It significantly reduces cell viability in various cancer cell lines.
PROTAC IDO1 Degrader-1 is the first potent IDO1 (indoleamine 2,3-dioxygenase 1) degrader that hijacks IDO1 to CRBN E3 ligase to introduce IDO1 into UPS and eventually achieve ubiquitination and degradation (DC50=2.84 μM). PROTAC IDO1 Degrader-1 moderately improves the tumor-killing activity of H ER2 CAR-T cells[1]. PROTAC IDO1 Degrader-1 (compound 2c) (10 μM; 24 hours) notably decreases IDO1 level induced by IFN-γ[1].PROTAC IDO1 Degrader-1 and IFN-γ (5 ng mL) are incubated with HeLa cells for 24 h, and a significant dose-dependent degradation is observed. PROTAC IDO1 Degrader-1 combined with chimeric antigen receptor-modified T (CAR-T) cells can improve the tumor-killing activity of HER-2 CAR-T cells[1].PROTAC IDO1 Degrader-1 induces significant and persistent degradation of IDO1 with maximum degradation (dmax) of 93% in HeLa cells[1].

PROTACBRD4 Degrader-9 (compound 8a) is a novel chemical compound consisting of ligands for von Hippel-Lindau and BRD4, connected by a PROTACmoiety. This compound can effectively degrade the BRD4 protein in PC3 prostate cancer cells. When conjugated with STEAP1 and CLL1 antibodies, PROTACBRD4 Degrader-9 exhibits potent activity, with respective DC50 values of 0.86 nM and 7.6 nM.
PROTACBRD4 degrader for PAC-1 (compound 5) is a chimeric BET degrader GNE-987 conjugated with a disulfide-containing linker[1]. This PROTAC-linker conjugate specifically targets and degrades BRD4, enabling selective proteolysis of PAC-1.
Halo PROTAC 1 is a PROTAC, which is a ligand having activity to bind to an intracellular proteins fused with HaloTag and a structure having activity to induce autophagy of an intracellular molecule are linked via a PEG linker[1].
(rel)-PROTAC ERRα Degrader-1 is a relative configuration of PROTAC ERRα Degrader-1, which is an estrogen-related receptor alpha (ERRa) degrader. PROTAC ERRα Degrader-1 consists of an MDM2 ligand bindingmoiety, a linker and an ERRa bindingmoiety [1].
PROTAC FLT-3 degrader 1 is a PROTAC FLT-3 degrader of internal tandem duplication (ITD) with an IC50 of 0.6 nM and exhibits anti-proliferative activity.
