The dysfunctional bromodomain PHD finger transcription factor (BPTF) exerts a pivotal influence in the occurrence and development of many human diseases, particularly cancers. Herein, through the structural decomposition of the reported BPTF inhibitor TP-238, the effective structural fragments were synthetically modified to obtain our lead compound DC-BPi-03. DC-BPi-03 was identified as a novel BPTF-BRD inhibitor with a moderate potency (IC50 = 698.3 ± 21.0 nM). A structure-guided structure-activity relationship exploration gave rise to two BPTF inhibitors with much higher affinities, DC-BPi-07 and DC-BPi-11. Notably, DC-BPi-07 and DC-BPi-11 show selectivities 100-fold higher than those of other BRD targets. The cocrystal structures of BPTF in complex with DC-BPi-07 and DC-BPi-11 demonstrate the rationale of chemical efforts from the atomic level. Further study showed that DC-BPi-11 significantly inhibited leukemia cell proliferation.
