Abstract: The invention provides epoxy and oxetane compositions including the novel acyloxy and N-acyl curing agents described herein. Use of invention curing agents result in cured adhesive compositions with remarkably increased adhesion and reduced hydrophilicity when compared to resins cured with other types of curing agents. Furthermore, the curatives of this invention do not interfere with free-radical cure and are thus suited for use in hybrid cure thermoset compositions.
Abstract: Devices, compositions, and methods are described which provide a tubular nanostructure targeted to a lipid bilayer membrane. The targeted tubular nanostructure can have a surface region configured to pass through a lipid bilayer membrane of a cell, a hydrophobic surface region flanked by two hydrophilic surface regions configured to form a pore in a lipid bilayer membrane of a cellular organelle, and at least one ligand configured to bind one or more cognates on the lipid bilayer membrane of the cellular organelle. The target cell can be, for example, a tumor cell, an infected cell, or a diseased cell in a subject. The tubular nanostructure can form a pore in the lipid bilayer membrane of the cellular organelle, e.g., mitochondria, which can permit transit or translocation of at least one compound across the membrane and cause cell death of the target cell.

Abstract: The invention includes methods of processing an initial di-carbonyl compound by conversion to a cyclic compound. The cyclic compound is reacted with an alkylating agent to form a derivative having an alkylated ring nitrogen. The invention encompasses a method of producing an N-alkyl product. Ammonia content of a solution is adjusted to produce a ratio of ammonia to di-carboxylate compound of from about 1:1 to about 1.5:1.

Abstract: This invention provides a method for preparing, in high purity and high yield, heterobifunctional derivatives of poly(ethylene glycol) or related polymers. A chromatographic purification step is not necessary in the method. In accordance with the method of the invention, an intermediate polymer having a formula of W-Poly-OH is provided bearing a removable group W at one terminus. The intermediate polymer W-Poly-OH is first altered by modifying the OH group to a first functional group X, followed by the removal of W to generate a second hydroxyl group. The latter hydroxyl group may then be further converted to a second functional group Y, thus providing the desired heterobifunctional derivative.

Abstract: In accordance with the present invention, there are provided thermosetting resin compositions with a reduced propensity to shrink in volume upon cure and methods of use therefor. The compositions of the present invention include compounds having aromatic, rigid-rod like spacer groups between the crosslinkable moieties. As such, these compounds impart a degree of liquid crystal-like character to the thermosetting resin composition which results in lower shrinkage upon cure. This effect follows from the well-known expansion that occurs when liquid crystal-like materials pass from a nematic liquid crystal-like state to an isotropic state. Further provided by the present invention are low shrinkage die attach pastes and methods of use therefor.

Abstract: A method of N-alkoxyalkylating ureides according to the invention comprises reacting a ureide of structure I with an alkylating agent of structure III in the presence of a basic catalyst in an aprotic reaction medium. The ureide may be a 5,5-disubstituted barbituric acid, or it may be phenytoin, glutethimide, and ethosuximide. The alkylating agent is an ester of a sulfonic acid. The base may be a hydride or amine. A preferred process comprises N-alkoxyalkylating 5,5-diphenyl-barbituric acid with methoxymethyl methanesulfonate in the presence of di-isopropyl ethyl amine and isolating the resultant N,N?-bismethoxymethyl-5,5-diphenyl-barbituric acid. The invention also contemplates the novel compounds N-methoxymethyl-5,5-diphenylbarbituric acid, N-methoxymethyl ethosuximide, and N-methoxymethyl glutethimide, and a method comprising administering them to a patient.
Abstract: In the presence of an imide compound (e.g., N-hydroxyphthalimide) shown by the formula (2): wherein R1 and R2 independently represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a cycloalkyl group; or R1 and R2 may bond together to form a double bond or an aromatic or non-aromatic ring; Y is O or OH and n=1 to 3; or the imide compound and a co-catalyst (e.g., a transition metal compound), an adamantane derivative having a functional group such as a nitro group, an amino group, a hydroxyl group, a carboxyl group, a hydroxymethyl group and an isocyanato group is oxidized with oxygen. According to the above method, an adamantane derivative having a hydroxyl group together with a functional group such as a nitro group, an amino group, a hydroxyl group, a carboxyl group, a hydroxymethyl group and an isocyanato group is efficiently obtained.
