BETd-260 (ZBC 260) (Synonyms: ZBC 260) |
Catalog No.GC32791 |
BETd-260 (ZBC 260) (ZBC 260) est un PROTAC connecté par des ligands pour Cereblon et BET, avec aussi peu que 30 pM contre la protéine BRD4 dans la lignée cellulaire de leucémie RS4;11. BETd-260 (ZBC 260) supprime puissamment la viabilité cellulaire et induit de manière robuste l'apoptose dans les cellules de carcinome hépatocellulaire (HCC).

BETd-260 is a potent BET degrader based on PROTAC technology, with an IC50 of 30 pM against BRD4 protein in RS4;11 leukemia cell line.
BETd-260 is a potent BET degrader based on PROTAC technology, with an IC50 of 30 pM for BRD4 protein in RS4;11 leukemia cell line. BETd-260 (ZBC260; Compound 23) shows inhibitory activity against the growth of RS4;11 leukemia cells and MOLM-13 cells with IC50s of 51 pM and 2.2 nM, respectively, and induces apoptosis in both RS4;11 and MOLM-13 cell lines at 3-10 nM[1].
BETd-260 (5 mg/kg, i.v., every other day, thrice a week for 3 weeks) causes rapid tumor regression with a maximum of >90% regression in mice bearing RS4;11 xenograft tumors, and with no body weight loss or other signs of toxicity in mice. BETd-260 (5 mg/kg, i.v.) degrades the BRD2, BRD3, and BRD4 proteins for more than 24 h, with robust cleavage of PARP and caspase-3, and strong down-regulation of c-Myc protein in RS4;11 xenograft mice model[1].
