CBPD-268
Based on 1 Customer Validation
CBPD-268 is a potent and orally active CBP/p300 PROTAC degrader with an DC50 value of ≤ 0.03 nM. CBPD-268 induces CBP/p300 degradation and inhibits cell growth. CBPD-268 shows antitumor activity. CBPD-268 has the potential for the research of AR-positive prostate cancer (Structure Note: Red, Androgen receptor degrader (HY-W248665A); Blue, CBP/p300 ligand (HY-161483); Black, Linker).

CBPD-268 (4, 24 h) shows high degradation efficiency for CBP and p300 protein with DC50s of 0.01, 0.03 nM at 4 h in 22Rv1 cells[1].
CBPD-268 shows degradation by binding to both CBP/p300 and CRBN protein[1].
CBPD-268 (0-1000 nM; 4 days) inhibits cell growth with IC50s of 3.7, 10.3, 4.6 nM for 22Rv1, LNCaP, VCaP cells, respectively[1].
