Melin, Lea; Gesner, Emily; Attwell, Sarah; Kharenko, Olesya A.; van der Horst, Edward H.; Hansen, Henrik C.; Gagnon, Alexandre published the artcile< Design and Synthesis of LM146, a Potent Inhibitor of PB1 with an Improved Selectivity Profile over SMARCA2>, COA of Formula: C8H8N2O, the main research area is LM146 quinazolin synthesis anticancer SAR PB1 bromodomain.
PB1 is a bromodomain-containing protein hypothesized to act as the nucleosome-recognition subunit of the PBAF complex. Although PB1 is a key component of the PBAF chromatin remodeling complex, its exact role has not been elucidated due to the lack of potent and selective inhibitors. Chem. probes that target specific bromodomains within the complex would constitute highly valuable tools to characterize the function and therapeutic pertinence of PB1 and of each of its bromodomains. Here, we report the design and synthesis of lead compound LM146, which displays strong stabilization of the second and fifth bromodomains of PB1 as shown by DSF. LM146 does not interact with bromodomains outside of sub-family VIII and binds to PB1(2), PB1(5), and SMARCA2B with KD values of 110, 61, and 2100 nM, resp., providing a ~34-fold selectivity profile for PB1(5) over SMARCA2.
