AP-1
Based on 1 Customer Validation
AP-1 is a targeted ALK PROTAC degrader. AP-1 effectively degrades various ALK fusion/mutation forms, including degradation of NPM-ALK (DC50 = 4.6 nM) and EML4-ALK (DC50 = 357.6 nM), and exhibits a typical hook effect at high concentrations. AP-1 inhibits phosphorylation of downstream STAT3, downregulates gene expression in the JAK-STAT pathway, and kills ALK-positive tumor cells via activating the caspase-3-dependent apoptosis pathway. AP-1 shows cytotoxicity against a variety of cancer cells and possesses anti-tumor activity. AP-1 can be used in research related to non-small cell lung cancer, neuroblastoma, and anaplastic large cell lymphoma.

AP-1 (0.2-1200 nM; 0-24 h) potently degrades NPM-ALK in Karpas299 cells via the ubiquitin-proteasome system, with a DC50 of 4.6 nM and a maximum degradation rate of 92.28%, and inhibits the phosphorylation of downstream STAT3[1].
AP-1 (30 nM-10 μM; 72 h) exhibits potent cytotoxic activity against Karpas299 cells with an IC50 of 0.1265 nM, and also shows cytotoxic activity against 3122 cells[1].
AP-1 (16 h) degrades EML4-ALK in H3122 cells in a concentration-dependent manner, with a DC50 of 357.6 nM and a maximum degradation rate of 81.34%, and this degradation effect is reversible after drug withdrawal[1].
Treatment with AP-1 for 16 h downregulates the gene expression of oncogenic ALK and JAK-STAT pathways in H3122 cells[1].
AP-1 induces the colocalization of ALK and CRBN in H3122 cells, promoting the formation of the ternary complex required for PROTAC-mediated protein degradation[1].
AP-1 (1 nM-100 μM; 16 h) exhibits high selectivity for ALK, as it does not degrade the off-target proteins Aurora A or FAK in Karpas299 cells[1].
AP-1 (0.0001 nM-100 μM; 24-60 h) exhibits high selectivity for ALK-dependent cells, and shows extremely low cytotoxicity in non-ALK-dependent THP-1, HeLa and 293T cells compared with LDK378[1].
AP-1 kills H3122 cells via an apoptotic pathway involving caspase-3 activation[1].

Cell Line:Karpas299 cells expressing NPM-ALK
-
Concentration:0.2, 0.4, 0.8, 1.5, 3, 6, 12, 25, 50, 100, 200, 400, 800 and 1200 nM (16 h); 100 nM (time-course); 1, 3, 10, 30, 100, 300 and 1000 nM (co-treated with 2 and 5 μM MG-132 (HY-13259), 16 h)
-
Incubation Time:16 h (concentration-dependent; proteasome inhibition); 0, 2, 4, 8, 16 and 24 h (time-course)
-
Result:Induced concentration-dependent degradation of NPM-ALK, with observable degradation at 10 nM, maximum degradation at ~300 nM, and slight reduction at 1 μM due to the hook effect.
Blocked NPM-ALK degradation when co-treated with MG-132, confirming proteasome-dependent activity.
Showed significant NPM-ALK degradation by 8 h, with maximum degradation at 16 h; p-ALK levels decreased with slower kinetics than total NPM-ALK.
Reduced p-STAT3 levels without affecting total STAT3.
Determined a DC50 of 4.6 nM and a maximum degradation level (Dₘₐₓ) of 92.28% for NPM-ALK from three repeated experiments.

Animal Model:Female NOD/SCID mice (6-8 weeks old) were subcutaneously inoculated with 1 × 106 NCI-H3122 cells in the right flank. When the tumors reached a mean volume of approximately 100 mm3, the treatment was initiated.

Dosage:25 mg/kg; 50 mg/kg; 100 mg/kg
-
Administration:i.p.; once every 2 days

Demonstrated equivalent antitumor efficacy to positive control LDK378 (25 mg/kg, TGI 57.66%) at 25 mg/kg dose.
Caused no significant body weight loss in treated mice.
Induced no notable liver or kidney function abnormalities at low-to-medium doses, with only slight increases in ALT, AST, and UREA-J indices at 100 mg/kg dose.
