Estrogen Receptor/ERR

Research Areas:  

Cancer

GNE-274 is a non-degrading estrogen receptor α (ERα/ESR1) modulator structurally similar to GDC-0927 (HY-111484). GNE-274 competes for binding to the ligand-binding domain of ERα and induces a coregulator-binding conformation similar to that of antagonists, yet retains partial agonistic transcriptional activity and does not promote ERα turnover. GNE-274 effectively inhibits E2-stimulated proliferation of ER-positive, HER2-negative breast cancer cells. GNE-274 promotes the recruitment of ERα to the nucleus and chromatin, increases chromatin accessibility, while largely maintaining the intranuclear mobility of ERα. GNE-274 can be used in research on ER-positive breast cancer and ERα transcriptional dynamics .

CGTDP is a fluorescent probe used for selective labeling of active-site arginine residues, detection of local polarity, and monitoring of conformational changes in enzyme active sites. CGTDP contains a neutral red moiety serving as a polarity-sensitive fluorophore, and a phenylglyoxal unit acting as an arginine-specific labeling group; it undergoes a selective reaction via its α-dicarbonyl moiety with the guanidyl group of arginine residues in enzyme active sites to form a covalent linkage, thereby enabling the reporting of the local microenvironment at the labeled site. The excitation/emission wavelengths are Ex/Em = 398/607 nm and Ex/Em = 507/607 nm; these wavelengths blue-shift in organic solvents, such as Ex/Em = 375/569 nm and Ex/Em = 469/569 nm in THF, and Ex/Em = 375/587 nm and Ex/Em = 470/587 nm in acetonitrile.
