  Synthesis and rat lens aldose reductase inhibitory activity of some benzopyran-2-ones

  摘要：

  A number of 4,7-disubstituted benzopyran-2-ones were synthesized and evaluated for crude rat lens aldose reductase inhibitory activity. Substituents on position 4 included CH3, CO2H, CH2CO2H, CH = CHCO2H, and CH2CH2CO2H. The aromatic substituents included OH, OCH3, OCOCH3, CH2CH3, and Cl. Also included in the study were 3-oxo-3H-naphtho[2,1-b]pyran-1-acetic, 2-oxo-2H-naphtho[1,2-b]pyran-4-acetic, and 1-naphthylacetic acids. The benzopyran and naphthopyran derivatives were prepared by the classical von Pechmann reaction. General structure-activity relationships reveal that optimal enzyme inhibitory activity is displayed by those compounds possessing the acetic acid moiety. For example, the most potent derivative, 3-oxo-3H-naphtho[2,1-b]pyran-1-acetic acid with an IC50 of 0.020 microM, is as potent as sorbinil (IC50 = 0.017 microM) in the crude rat lens aldose reductase assay.

  Oligonucleotide-fluorophore-quencher conjugates wherein the fluorophore moiety has emission wavelengths in the range of about 300 to about 800 nm, and or where the quencher includes a substituted 4-(phenyldiazenyl)phenylamine structure provide improved signal to noise ratios and other advantageous characteristics in hybridization and related assays. The oligonucleotide-fluorophore-quencher conjugates can be synthesized by utilizing novel phosphoramidite reagents that incorporate the quencher moiety based on the substituted 4-(phenyidiazenyl)phenylamine structure, and or novel phosphoramidite reagents that incorporate a fluorophore moiety based on the substituted coumarin, substituted 7-hydroxy-3H-phenoxazin-3-one, or substituted 5,10-dihydro-10-[phenyl]pyrido[2,3-d;6,5-d′]dipyrimidine-2,4,6,8-(1H,3H,7H,9H,10H)-tetrone structure.
