CFT8634
Based on 1 publication(s) in Google Scholar
CFT8634 is an orally active BRD9 PROTAC degrader with a DC50 of 0.003 μM (HEK293T.166). CFT8634 recruits the CRBN E3 ubiquitin ligase to form a ternary complex, triggering CRBN-catalyzed BRD9 polyubiquitination and 26S proteasome-mediated degradation. CFT8634 induces sustained tumor regression and inhibits tumor growth in mouse models. CFT8634 can be used in research related to synovial sarcoma, SMARCB-1-deficient cancers, acute myeloid leukemia, malignant rhabdoid tumors, and multiple myeloma.

CFT8634 potently and selectively degrades BRD9 in synovial sarcoma and SMARCB-1-deficient cells, with a DC50 of 2.7 nM[1].
CFT8634 (10 μM; 2 h) potently degrades BRD9 in HEK293T.166 cells, with a DC50 of 0.003 μM and an Emax of 4%[2].
CFT8634 (100 nM; 4 h) selectively degrades BRD9 in HSSYII human synovial sarcoma cells[2].
The degradation of BRD9 induced by CFT8634 (1 μM; 4 h) in Yamato-SS cells depends on the ubiquitin-proteasome system, BRD9 binding, and CRBN binding[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
