Exploiting the 7-methylimidazo[1,5-a]pyrazin-8(7H)-one scaffold for the development of novel chemical inhibitors for Bromodomain and Extraterminal Domain (BET) family
The bromodomain and extraterminal (BET) family of proteins play a crucial role in promoting gene expression of critical oncogenes. NovelBETbromodomaininhibitors with excellent potency, drug metabolism and pharmacokinetics (DMPK) properties were in strong need for development. We reported a series of potential BETinhibitors through incorporation of imidazole into pyridine scaffold. Among them, a
compound 27 and 29 exhibited robust potency of BRD9 inhibition with IC50 values of 35 and 103 nM respectively. Docking studies were performed to explain the structure-activity relationship. Furthermore, compound 27 potently inhibited cell proliferation in cell lines A549 and EOL-1 with an IC50 value of 6.12 μM and 1.76 μM respectively. The chemicalprobe, compound 27, was identified that should prove to
The present invention relates to substituted heterocyclic derivative compounds, compositions comprising said compounds, and the use of said compounds and compositions for epigenetic regulation by inhibition of bromodomain-mediated recognition of acetyl lysine regions of proteins, such as histones. Said compositions and methods are useful for the treatment of cancer and neoplastic disease.

The Rh(III)-catalyzed C–H functionalization and subsequent oxidative annulation between 5-aryl pyrazinones and internalalkynes are reported. This protocol provides facile access to a wide range of pyrazinone-linked naphthalenes via the C(sp2)–H alkenylation and subsequent annulation. This transformation is characterized by mild conditions, simplicity, and excellent functional group compatibility.
