SCR-7952
Based on 1 Customer Validation
SCR-7952 is an orally active MAT2A allosteric inhibitor (IC50 = 18.7 nM; Ki = 14.49 nM; Kd = 0.56 nM). SCR-7952 reduces SAM production, PRMT5 activity, and SDMA marks by binding to the MAT2A allosteric pocket, and dysregulates RNA splicing through FANCA intron retention, thereby selectively inhibiting the proliferation of MTAP-deleted cancer cells and producing synergistic effects with PRMT5 inhibitors. SCR-7952 can be used for research on MTAP-deleted cancers.

In Vivo
SCR-7952 (0.3 mg/kg; p.o.; once daily) combined with Onametostat (JNJ-64619178) (HY-101564) produces near-complete tumor stasis in the HCT116 MTAP-/- xenograft model, with a TGI of 94.4%[1].

-
Animal Model:Nu/Nu (female)[1]
-
Dosage:0.25, 0.5, 1.0, or 3.0 mg/kg
-
Administration:p.o. (oral gavage); once daily (q.d.)
-
Result:Compared with the vehicle group, oral administration of SCR-7952 led to a significant dose-dependent reduction in tumor growth.
Tumor growth inhibition (TGI) was 60.0% at 0.5 mg/kg, 62.7% at 1.0 mg/kg, and 82.9% at 3.0 mg/kg.
In a satellite group, SAM levels in HCT116 MTAP-/- xenograft tumors and mouse plasma were significantly decreased, with 53.56-68.72% inhibition at 2 or 4 h post final dose in the low group.
-
Animal Model:Nu/Nu (female)[1]
-
Dosage:0.3 mg/kg
-
Administration:p.o. (oral gavage); once daily (q.d.)
-
Result:Modest efficacy was observed with either SCR-7952 (0.3 mg/kg) or JNJ-64619178 (1.0 mg/kg) alone.
Almost complete tumor stasis was achieved when both agents were combined, significantly better than monotherapies (TGI 94.4% vs. 55.0% vs. 54.0%).
SCR-7952 (0.3 mg/kg) or JNJ-64619178 (1.0 mg/kg) alone both led to a remarkable reduction of SDMA levels.
In the combination group, a significant reduction of SDMA levels was observed compared with single-agent groups.
