SJPYT-195
Based on 1 Customer Validation
SJPYT-195 is a molecular glue degrader targeting GSPT1, with a DC50 of 310 nM. SJPYT-195 mediates CRBN-dependent and proteasome-dependent degradation of GSPT1 by forming a stable ternary complex with CRBN and GSPT1. As a secondary effect of GSPT1 degradation, SJPYT-195 induces a decrease in PXR protein levels. SJPYT-195 is applicable to research related to acute myeloid leukemia.

SJPYT-195 (0.001-10 μM; 24 h) mediates CRBN- and proteasome-dependent degradation of GSPT1 in SNU-C4 3xFLAG-PXR KI cells at concentrations lower than those needed for PXR reduction[1].
SJPYT-195 (0.00001-100 μM; 72 h) is cytotoxic to SNU-C4 3xFLAG-PXR KI cells with a CC50 of 440 nM after 72 h treatment, with cytotoxicity partially mediated by GSPT1 degradation[1].
SJPYT-195 (10 μM; 24 h) induces complete loss of GSPT1 protein in SNU-C4 3xFLAG-PXR KI cells[1].
