Fluorescent analogs of the gypsy moth sex pheromone (+)-disparlure and its enantiomer (-)-disparlure were designed, synthesized, and characterized. The fluorescently labeled analogs 6-FAM (+)-disparlure I and 6-FAM (-)-disparlure II were prepared by copper-catalyzed azide-alkyne cycloaddition of disparlure alkyne and 6-FAM azide. These fluorescent disparlure analogs I and II were used to measure disparlure binding to two pheromone-binding proteins from the gypsy moth, Lymantria dispar Pheromone-Binding Protein 1 (LdisPBP1) and LdisPBP2. The fluorescence binding assay showed that LdisPBP1 has a stronger affinity for 6-FAM (-)-disparlure II, whereas LdisPBP2 has a stronger affinity for 6-FAM (+)-disparlure I, consistent with findings from previous studies with disparlure enantiomers. The 6-FAM disparlure enantiomers appeared to be much stronger ligands for LdisPBPs, with binding constants (Kd) in the nanomolar range, compared to the fluorescent reporter 1-NPN (which had Kd values in the micromolar range). Fluorescence competitive binding assays were used to determine the displacement constant (Ki) for the disparlure enantiomers in competition with fluorescent disparlure analogs binding to LdisPBP1 and LdisPBP2. The Ki data show that disparlure enantiomers can effectively displace the fluorescent disparlure from the binding pocket of LdisPBPs and, therefore, occupy the same binding site. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Related Products of 111-46-6).
2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Related Products of 111-46-6
