USP7-IN-4(USP7 inhibitor ALM4) is a non-competitive, potent and selective inhibitor of USP7 (ubiquitin-specific protease 7) with an IC50 = 6 nM, up-regulates p53 and p21, down-regulates MDM2, increases the level of ubiquitination of MDM2, and exhibits anti-proliferative activity in a variety of cancer cell lines, with an EC50 = 2.0 nM in RS4;11 (acute lymphoblastic leukemia cell line) .

MD-224 is a highly potent and efficacious MDM2 degrader based on the proteolysistargeting chimera (PROTAC) concept,and as a new class of anticancer agent.

PROTAC BET degrader-2 is a highly potent degrader of Bromodomain and Extra-Terminal (BET) proteins, with an IC50 of 9.6 nM.

Lenalidomide-C4-NH2 hydrochloride is a Cereblon ligand derived from Lenalidomide. It serves as a recruiting agent for the CRBN protein. The compound, known as PROTAC (Compound 24), can be formed by linking Lenalidomide-C4-NH2 hydrochloride to the ligand for the protein. It exhibits inhibitory effects with IC50s of 0.98 nM and 13.7 nM against the growth of RS4;11 and MOLM-13 acute leukemia cell lines, respectively[1].

KT-253 is a p53 stabilizer and a PROTAC degrader of MDM2 (DC50=0.4 nM). It inhibits the proliferation of cancer cells RS4;11 with an IC50 of 0.3 nM, induces cell cycle arrest in the G2 M phase, and triggers apoptosis. In mouse models, KT-253 demonstrates antitumor activity. (Pink: ligand for target protein MDM2 ligand 4; Black: linker; Blue: ligand for E3 ligase cereblon)
