摘要:
A resin composition curable through a Michael reaction between (a) a component having a plurality of .alpha., .beta.-unsaturated carbonyl groups and (b) a component having a plurality of activated methylene, activated methyne or hydroxyl groups is disclosed. The curing reaction is catalyzed with a quaternary ammonium, quaternary phosphonium or tertiary sulfonium salt in the presence of an epoxy compound independently added to the composition or covalently attacted to either component (a) or component (b).
摘要:
A one-component, thermosetting resin composition curable through a Michael reaction between (a) a component having a plurality of .alpha., .beta.-unsaturated carbonyl groups and (b) a component having a plurality of activated methylene of activated methyne groups is disclosed. The curing reaction is catalyzed with a quaternary ammonium, quaternary phosphonium or tertiary sulfonium salt in the presence of a five-membered cyclic carbonate compound independently added to the composition or covalently attached to either component (a) or component (b).
摘要:
A malonate group-containing acrylate monomer is produced by a transesterification reaction of dialkyl malonate with a hydroxyalkyl (meth)acrylate or a polyalkylene glycol mono(meth)acrylate. The malonate group-containing acrylate monomer finds use in the production of an acrylic polymer capable of crosslinking through a Michael reaction with an .alpha., .beta.-unsaturated carbonyl compound or resin.
摘要:
A resin composition curable through a Michael reaction between (a) a component having a plurality of .alpha.,.beta.-unsaturate carbonyl groups and (b) a component having a plurality of activated methylene group in the presence of a catalyst is disclosed. The activated methylene component is a polymer of an asymmetric malonate ester in which one of carboxyl groups is esterified with an alkanol while the other carboxyl group is esterified with hydroxyalkyl (meth) acrylate or polyoxyalkylene glycol mono(meth)acrylate.

Methods for treating a non-spasm caused pain by peripheral administration to a patient of a therapeutically effective amount of a neurotoxin, such as a botulinum toxin.
摘要:
The present invention provides for methods of modulating the degradation rate of a toxin in a cell, thereby modulating the half-life of the toxin. Particularly, the invention features methods of modulating the degradation rate of a toxin by modulating fusion between a lysosome and an endosome that carries the toxin in the cell.
摘要:
The present invention is directed to multivalent Clostridial neurotoxin derivatives having more than one binding domain directed to a cell surface feature of a target cell. Such modified neurotoxins are useful as therapeutic compositions to prevent exocytosis and secretion by the target cell. Conditions in which such compositions man be useful include, without limitation, disorders of the sensory or motor nervous system, acute or chronic pain, cancer, pancreatitis, hyperhydrosis, glandular disorders, viral infections, cystic fibrosis and the like. The invention is also directed to methods of using and administering such a composition, and methods of treating a given condition using such a composition.
摘要:
The present invention provides a method of determining the presence or activity of a clostridial toxin by (a) treating with a sample, under conditions suitable for clostridial toxin protease activity, a clostridial toxin substrate which includes a fluorophore; a bulking group; and a clostridial toxin recognition sequence containing a cleavage site that intervenes between the fluorophore and the bulking group; (b) exciting the fluorophore with plane polarized light; and (c) determining fluorescence polarization of the treated substrate relative to a control substrate, where a change in fluorescence polarization of the treated substrate as compared to fluorescence polarization of the control substrate is indicative of the presence or activity of the clostridial toxin.
