The present invention relate to a novel silane coupling agent and a medical and/or dental curable composition comprising the same. It is an object of the present invention to provide a novel silane coupling agent that imparts high affinity to a radical polymerizable monomer, thereby imparting high mechanical strength, flexibility and durability when used for a medical and/or dental curable composition, and an inorganic filler surface-treated with the novel silane coupling agent and a novel medical and/or dental curable composition. A silane coupling agent including repeating units such as a urethane bond and polyethylene glycol (ether bond) at a specific position is used.
Several 3-carbonyl (1–26), 3-acyl (27–52), and 3-carboxyhydrazido (53–58) coumarins have been synthesized in high yields (72–99%) and tested in vitro for their human monoamine oxidase A and B (hMAO-A and hMAO-B) inhibitory activity. Different substituents on the coumarin nucleus were evaluated for their effect on biological activity and isoform selectivity. Substitution at position C7 of the 3-ethyl

varying degrees of α-glucosidaseinhibitory and DPPHscavengingactivity. Compound 4x emerged as the most potent α-glucosidase inhibitor in present series of compounds owing to the presence of 3-acetyl-6-(6-methoxy-3-pyridyl) group on chromenone; however, it could not display DPPHscavengingactivity and was found to be mixed non-competitive type inhibitor of rat intestinal α-glucosidase. When tested in
The present invention provides a dental adhesive exhibiting excellent initial bond strength and bond durability to both enamel and dentin. The present invention relates to a dental adhesive containing: an asymmetric acrylamide-methacrylic acid ester compound (a); an acid group-containing (meth)acrylic polymerizable monomer (b); and a water-soluble polymerizable monomer (c). The asymmetric acrylamide-methacrylic acid ester compound (a) is represented by the following general formula (1):
