BET BD2-IN-3 (compound I-58) 作为针对 BET BD2 结构域的抑制剂,有能力在小鼠身上展示外周器官和组织中的适宜生物分布。此化合物可通过 [11C] 进行放射性标记,并利用于正电子发射断层扫描 (PET) 成像技术。其在 PET 成像中的应用证明了其在生物学分布方面的有效性。
BET-IN-24 (example 2) is a bromodomain and extra-terminal (BET) inhibitor used in studies of virology, heart failure, inflammation, central nervous system (CNS) diseases, and various cancers.
(S,R,S)-AHPC-Me dihydrochloride, also known as VHL ligand 2 dihydrochloride, is a chemical compound utilized in the synthesis of ARV-771. ARV-771, a BET PROTAC degrader relying on von Hippel-Landau (VHL) E3 ligase, demonstrates potent degradation of BET proteinin castration-resistant prostate cancer (CRPC) cells, with a DC50 of less than 1 nM. This compound serves as the VHL ligand, specifically the (S,R,S)-AHPC-based VHL ligand, that facilitates the recruitment of von Hippel-Lindau (VHL) protein.
TW9 is a dual inhibitor of bromodomain 2 (BD2) in bromodomain-containing protein 4 (BRD4) and histone deacetylase 1 (HDAC1; IC50s = 0.074 and 0.29 μM, respectively).1It is selective for BD2 over BD1 in BRD4 (IC50= 0.72 μM) and for HDAC1 over HDAC2 (IC50= 2.5 μM). TW9 (50 nM) induces apoptosis in, and inhibits proliferation of, MIA PaCa-2 pancreatic cancer cells. It induces cell cycle arrest at the G1phase in HPAC pancreatic cancer cells when used at a concentration of 2 μM. TW9 acts synergistically with gemcitabine to reduce the viability of HPAC cells. 1.Zhang, X., Zegar, T., Weiser, T., et al.Characterization of a dual BET HDAC inhibitor for treatment of pancreatic ductal adenocarcinomaInt.
