IUPAC Name: (2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-N-(4-((1-((S)-4-(4-chlorophenyl)-2,3,9-trimethyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepin-6-yl)-2-oxo-6,9,12-trioxa-3-azatetradecan-14-yl)carbamoyl)-2-methoxyphenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamide
InChIKey: IPNTVOAQOGRLQB-JJMBTQCASA-N
SMILES: ClC(C=C1)=CC=C1C2=N[C@H](C3=NN=C(C)N3C4=C2C(C)=C(C)S4)CC(NCCOCCOCCOCCNC(C5=CC(OC)=C(NC([C@H]6[C@H](C7=C(F)C(Cl)=CC=C7)[C@](C8=CC=C(Cl)C=C8F)(C#N)[C@H](CC(C)(C)C)N6)=O)C=C5)=O)=O
Biological Activity: A1874 is an orally active BRD4 PROTAC degrader with a DC50 of 32 nM. A1874 degrades BRD4 via the ubiquitin-proteasome system by recruiting the MDM2 E3 ligase, while disrupting the MDM2-p53 interaction to stabilize p53 and upregulate p21, thereby inducing cell cycle arrest and apoptosis. A1874 exhibits selectivity for wild-type p53 cells and MDM2-amplified tumors, and it can be used in research on breast cancer, colorectal cancer, melanoma, lung cancer, lymphoma, myeloid leukemia, osteosarcoma, and glioblastoma[1][2][3][4][5].
