BAY1238097 是一种有效的、BET 与组蛋白结合的选择性抑制剂，通过下调c-Myc水平及下游转录组，在AML (急性髓性白血病) 和MM (多发性骨髓瘤) 模型中表现出较强的抗增殖活性 (IC50值<100 nM)。
| 生物活性 | BAY1238097 is a potent and selective inhibitor ofBET binding to histonesand has strong anti-proliferative activity in different AML (acute myeloid leukemia) and MM (multiple myeloma) models through down-regulation ofc-Myclevels and its downstream transcriptome (IC50<100 nM). |
| IC50& Target | IC50:< 100 nM (BET in a TR-FRET assay)[1]. |
体外研究
(In Vitro) | BAY 1238097 shows strong inhibitory activity (IC50< 100 nM) in a TR-FRET assay using BET BRD4 bromodomain 1 and an acetylated peptide derived from histone H4. In the NanoBRET assay, the interaction between BRD4 (IC50=63 nM), BRD3 or BRD2 (IC50=609 nM) and H4 (IC50=2430 nM) is inhibited[1].
BAY 1238097 has in vitro anti-tumour activity in lymphoma models. BAY 1238097 affects the gene expression of GCB DLBCL cells. At the gene level, BTK, CCDC86, CCND2, CD19, CD27, FAIM, FCMR (FAIM3), IL7R, IRAK1, MAPK13, MYB, MYC, PDE4B, TNFRSF13B, TNFRSF17 are among the top downregulated genes. Beside histone-coding genes, the upregulated genes include CCL5, CDKN2C, CD69, JUN, and MKNK2[2].

(In Vivo) | BAY 1238097 shows strong efficacy in the AML and MM models. BAY 1238097 has in vivo anti-tumour activity in lymphoma models[1][2].
BAY 1238097 is well tolerated at 10-15 mg/kg applieddailyover 9-14 days in different disease models, with no obvious toxicity[1][2].
| Animal Model: | Severe combined immunodeficiency (SCID) female mice (9-12 weeks old) inoculated subcutaneously into the right flank with 5×106SU-DHL-8 cells/mouse suspended in 0.1 mL of matrigel or with O | | Dosage: | 15 mg/kg (maximal tolerated dose). | | Administration: | Orally daily for 12 days (on day 21 post-tumour inoculation). | | Result: | Showed strong efficacy in the AML models THP-1, MOLM-13 and KG-1, with T/C between 13 and 20%. Also active in MM models in a human IGH-cyclin D1 translocated MOLP-8 model with a T/C of 3%[2].
