aTAG 4531
Based on 1 Customer Validation
aTAG 4531 is a PROTAC-class degrader that induces the degradation of the MTH1/aTAG fusion protein by recruiting cereblon, with a DC50 of 0.28 nM in Jurkat cells. aTAG 4531 inhibits MTH1 enzymatic activity, with a Ki of 1.8 nM. aTAG 4531 rapidly, selectively and reversibly regulates SMART-CAR protein levels, CAR-mediated target cell killing and IL-2 release, and is applicable both in vitro and in vivo. aTAG 4531 can be used in studies of targeted protein degradation, target validation and CAR-T activity regulation.

aTAG 4531 binds to the purified CRBN/DDB1 complex with a KD value of 385 nM[1].
aTAG 4531 potently inhibits the enzymatic activity of purified human MTH1 aTAG, with a Ki value of 1.8 nM[1].
The degradation of SMART-CAR and MTH1 induced by aTAG 4531 (10 nM; 4 h) in Jurkat T cells is reversible, and protein levels recover to basal levels within 72 h after degradation 剂 elution[1].
aTAG 4531 (4 h) potently degrades SMART-CAR-HiBiT in Jurkat T cells, with a DC50 of 0.28 nM and an Emax of 11% after 4 h of treatment[1].
Treatment of Jurkat T cells with aTAG 4531 (1-10000 nM; 6 h) induces concentration-dependent degradation of SMART-CAR-HA and MTH1[1].
The degradation of SMART-CAR and MTH1 induced by aTAG 4531 (100 nM; 6 h) in Jurkat T cells is mediated via the CRBN-dependent proteasomal pathway, which is confirmed by rescue experiments using pathway-specific inhibitors and competitors[1].
aTAG 4531 (0.1-1000 nM) regulates CAR-T-mediated target cell killing in a concentration-dependent manner, with the peak inhibitory effect on Raji cell killing and the maximum degradation of SMART-CAR both occurring at 10 nM[1].
aTAG 4531 (1-10000 nM) regulates CAR-T-mediated IL-2 cytokine release in a concentration-dependent manner, with the inhibitory effect peaking at 1 and 10 nM[1].

Cell Line:SMART-CAR (HA-tagged CD19 CAR fused to MTH1 aTAG) expressing Jurkat T-cells
-
Concentration:1-10000 nM
-
Incubation Time:6 h
-
Result:Induced concentration-dependent degradation of SMART-CAR-HA and endogenous MTH1.
Caused near-complete degradation observed at 10 nM.

Cell Line:SMART-CAR (HA-tagged CD19 CAR fused to MTH1 aTAG) expressing Jurkat T-cells
-
Concentration:100 nM; 10 μM Pomalidomide (HY-10984)
-
Incubation Time:6 h (aTAG 4531 incubation); 1 h (Pomalidomide pre-incubation)
-
Result:Induced degradation of SMART-CAR and MTH1 that was completely rescued by pre-treatment with Bortezomib (HY-10227), MLN4924 (HY-10227), Pomalidomide, or MTH1 inhibitor.
Confirmed the degradation is mediated via the CRBN-dependent proteasomal pathway.
