DC-SIGN (dendritic cell-specific intercellular adhesion mol.-3-grabbing non-integrin) is a pattern recognition receptor expressed on immune cells and involved in the recognition of carbohydrate signatures present on various pathogens, including HIV, Ebola, and SARS-CoV-2. Therefore, developing inhibitors blocking the carbohydrate-binding site of DC-SIGN could generate a valuable tool to investigate the role of this receptor in several infectious diseases. Herein, we performed a fragment-based ligand design using 4-quinolone as a scaffold. We synthesized a library of 61 compounds, performed a screening against DC-SIGN using an STD reporter assay, and validated these data using protein-based 1H-15N HSQC NMR. Based on the structure-activity relationship data, we demonstrate that ethoxycarbonyl or dimethylaminocarbonyl in position 2 or 3 is favorable for the DC-SIGN binding activity, especially in combination with fluorine, ethoxycarbonyl, or dimethylaminocarbonyl in position 7 or 8. Furthermore, we demonstrate that these quinolones can allosterically modulate the carbohydrate binding site, which offers an alternative approach toward this challenging protein target.
Formula: C10H16O5, Diethyl ethoxymethylenemalonate is a useful research compound. Its molecular formula is C10H16O5 and its molecular weight is 216.23 g/mol. The purity is usually 95%.
Diethyl ethoxymethylidenemalonate is a matrix effect reagent used in analytical chemistry. It is often used as a substrate for the cycloaddition process, which produces malondialdehyde and hydrochloric acid. The UV-absorption of the malondialdehyde can be measured to determine the concentration of the sample. Diethyl ethoxymethylidenemalonate is also used as a dna template in binding constants, where it binds with amines to form complexes that are then analyzed by light emission. It has been shown to have an inhibitory effect on gyrase and trifluoroacetic acid, both enzymes involved in DNA replication., 87-13-8.
