WebJun 1, 2024 · The green fluorescent protein (GFP) is extensively used as a biomarker for fluorescence biological imaging. The chromophore in GFP is only fluorescent when confined into the β–barrel of the protein. Similarly, synthetic analogues of the fluorophore of GFP are usually non-emissive in solution, due to free rotation around the aryl-alkene bond and … WebFluorescent SAM an-alogs based on 2-aminopurine have been prepared (Ottink et al., 2010); however, it is known that the 6-amino group is important for SAM-I riboswitch binding …
WebHere, we chemically functionalized human (H2) relaxin, the RXFP1-selective relaxin analog H2:A(4-24)(F23A), and INSL3 to accommodate a fluorophore without marked reduction in binding or activation propensity. Chemical synthesis of the two chains for each peptide was followed by sequential regioselective formation of their three disulfide bonds. WebJan 1, 2024 · Fluorescently labeled compounds are useful tools for high-throughput screenings of large compound libraries. Here we utilized the azaindole-based scaffold of FDA-approved BRAF inhibitor vemurafenib 1, which displays off-target activity on MKK4, as a starting point in our fluorescent compound design. Chemical variation of the scaffold and ...
