AQ-101
AQ-101 is a MDM2 degrader. Upon binding to MDM2, it blocks the MDM2-MDM4 interaction, inducing autoubiquitination and proteasome-mediated degradation of MDM2. AQ-101 activates p53, upregulates downstream targets including p21 and PUMA, and induces apoptosis and cell cycle arrest in tumor cells. AQ-101 inhibits the progression of acute lymphoblastic leukemia in xenograft animal models. AQ-101 can be used for research related to acute lymphoblastic leukemia.

In Vitro
AQ-101 binds non-covalently to the MDM2 RING domain with a Kd of 0.31 μM, and does not bind to the MDM4 RING domain; it also binds to MDM2 with a Kd of 0.37 μM, and does not bind to MDM4[1].
AQ-101 (0.25-2 μM; 0-24 h) induces dose-dependent downregulation of MDM2 protein, which starts at 2 h post-treatment, while upregulating p53 expression in EU-1 ALL cells. It reduces the stability of MDM2 protein and increases the stability of p53 protein in EU-1 ALL cells, and the degradation of MDM2 depends on the proteasome pathway[1].
AQ-101 (0.25-2 μM; 20-24 h) potently induces cytotoxicity in ALL cell lines (Sup-B13, EU-1, EU-3) expressing wild-type p53/MDM2, but shows reduced activity in the ALL cell line expressing mutant p53/MDM2 (EU-6) and the p53-deficient/MDM2-deficient ALL cell line (EU-8); it also exhibits only extremely low cytotoxicity against normal human NBMM cells[1].
AQ-101 (0.5-1 μM; 10 days) potently inhibits the colony-forming growth of EU-1 ALL cells, shows weak activity against EU-6 and EU-8 ALL cells, and exerts only extremely weak inhibitory effects on the colony-forming growth of normal human NBMM cells[1].
AQ-101 (24 h) induces cytotoxicity in HeLa, K562, Molt-4 and EU-1 cancer cell lines, with IC50 values ranging from 0.69 µM to 2.21 µM[2].
AQ-101 (0.5-1 μM; 24 h) potently induces apoptosis in acute lymphoblastic leukemia (ALL) cell lines (Sup-B13, EU-1, EU-3) expressing wild-type p53/MDM2, while its activity is reduced in ALL cell lines expressing mutant p53/MDM2 (EU-6) as well as those with p53 deletion/MDM2 deletion (EU-8)[1].
AQ-101 (0.5-1 μM; 8 h) induces p53-dependent G1 cell cycle arrest in wild-type p53 EU-1 acute lymphoblastic leukemia (ALL) cells, and G2-M cell cycle arrest in mutant p53 EU-6 ALL cells[1].
