商品描述
UNC3866 is a potent and selective antagonist of CBX4 and CBX7 chromodomains with (Kd ≈ 100 nM). It is 6- to 63-fold selective for these chromodomains over the other CBX and CDY chromodomains.

In vitro(体外研究)
UNC3866 is a potent antagonist of the CBX7-H3 interaction(IC50 = 66±1.2 nM). The affinity of UNC3866 for CBX2, -4, -6 and -8 is also surprisingly well correlated with the percent sequence identity of each chromodomain relative to that of CBX7. UNC3866 is equipotent for CBX4, which is most similar to CBX7, while it is 18-, 6- and 12-fold selective for CBX4/7 over CBX2, -6 and -8, respectively. Additionally, UNC3866 is 65-fold selective for CBX4/7 over CDY1 and 9-fold selective for CBX4/7 over CDYL1b and CDYL2. UNC3866 antagonizes PRC1 chromodomains in cells. Thought the permeability of UNC3866 is low, it is sufficiently cell permeable and stable to evaluate its ability to engage and antagonize the functions of its chromodomain targets in cells. UNC3866 inhibits PC3 cell proliferation .
In vivo(体内研究)
UNC3866 is the predominant species in plasma at all time points tested relative to UNC4007 and shows 25% bioavailability and moderate clearance. While these PK results are promising for a peptidic compound, the use of UNC3866 in vivo may be limited because of the high circulating levels required for intracellular target engagement due to its poor cell permeability. The potential utility of UNC3866 at higher doses for in vivo experiments is currently under investigation.
