Structural highlights
Function[BRD2_HUMAN] May play a role in spermatogenesis or folliculogenesis (By similarity). Binds hyperacetylated chromatin and plays a role in the regulation of transcription, probably by chromatin remodeling. Regulates transcription of the CCND1 gene. Plays a role in nucleosome assembly.[1] Publication Abstract from PubMedA number of reports have recently been published describing the discovery and optimization of bromo and extraterminal inhibitors which are selective for the second bromodomain (BD2); these include our own work toward GSK046 (3) and GSK620 (5). This paper describes our approach to mitigating the genotoxicity risk of GSK046 by replacement of the acetamide functionality with a heterocyclic ring. This was followed by a template-hopping and hybridization approach, guided by structure-based drug design, to incorporate learnings from other BD2-selective series, optimize the vector for the amide region, and explore the ZA cleft, leading to the identification of potent, selective, and bioavailable compounds 28 (GSK452), 39 (GSK737), and 36 (GSK217). Template-Hopping Approach Leads to Potent, Selective, and Highly Soluble Bromo and Extraterminal Domain (BET) Second Bromodomain (BD2) Inhibitors.,Aylott HE, Atkinson SJ, Bamborough P, Bassil A, Chung CW, Gordon L, Grandi P, Gray JRJ, Harrison LA, Hayhow TG, Messenger C, Mitchell D, Phillipou A, Preston A, Prinjha RK, Rianjongdee F, Rioja I, Seal JT, Wall ID, Watson RJ, Woolven JM, Demont EH J Med Chem. 2021 Mar 4. doi: 10.1021/acs.jmedchem.0c02156.
