GtoPdb Ligand ID: 10743

Synonyms: NHWD870
Compound class: Synthetic organic
Comment: NHWD-870 is an orally bioavailable bromodomain and extra-terminal (BET) inhibitor, that exhibits selectivity for bromodomain containing 4 (BRD4) [2]. It was developed for anti-cancer potential. In vitro, it is more potent than clinical stage BET inhibitors such as birabresib (OTX-015) and molibresib (GSK-525762). NHWD-870 potently reduces tumour growth in a number of different mouse models of cancers, including lung and ovarian tumours, lymphoma, and melanoma.

Bioactivity Comments
In cellular assay using A375 melanoma cells, NHWD-870 inhibited proliferation with an IC50 of 2.5 nM [2]. In the same assay the IC50s for birabresib and molibresib are 34.8 and 35.6 nM respectively. NHWD-870 has been used to show that BET inhibition (which inhibits c-MYC transcription) more effectively reduces proliferation in organoids produced from pancreatic ductal adenocarcinomas (PDAC) with a high c-MYC signature compared to low-MYC PDAC organoids [1].
