To 100° c., and (a2) 1%-70% by weight, based on the mass of the nonvolatile fraction of (a), of at least one oh-functional (meth)acrylate (co)polymer having an oh number of 60-200 mg koh/g and a glass transition temperature tg of −100° c.
|Matrices comprising modified polysaccharides and modified polysaccharides|
The present invention discloses a matrix comprising a modified primary hydroxyl groups containing polysaccharide comprising repeating disaccharide units wherein in at least part of the disaccharide units the primary hydroxyl group is replaced by functional groups selected from halide groups or groups comprising sulfur or phosphorus atoms, like e.g. Sulfate groups, sulfonate groups, phosphonate groups and phosphate groups..
|Method of acylating a peptide or protein|
A method for selectively acylating an amino group in a peptide or protein which has two or more reactive nucleophilic functional groups is described.. .
|High solids content dendrimer polymer composition|
The present invention relates to a polymer composition comprising: (i) one or more dendritic polymers; and (ii) a reactive diluent that is capable of being chemically coupled to the functional groups of the dendritic polymers, wherein when the dendritic polymer is coupled to the reactive diluent in the presence of a cross-linker, a polymerized solid is formed at high concentrations in a liquid medium. The present invention further relates to methods of preparing the polymer composition and its use in forming coatings..
|Cross-linked poly-e-lysine non-particulate support|
The invention provides a non-particulate cross-linked poly-ε-lysine polymer. The poly-ε-lysine and cross linker are linked by amide bonds and may the cross linker has at least two functional groups capable of reacting with an alpha carbon amine of poly-ε-lysine.
|Methods and compositions for treatment of diabetes and dyslipidemia|
R1 is selected from a group consisting of hydroxy, alkoxy, amine, alkyl, haloalkyl, nhso2r, or nhcor wherein r is selected from alkyl or cycloalkyl, nhr′ wherein r′ is alkyl or cycloalkyl optionally substituted by hydroxy or alkoxy; and n1 and n2 are independently selected from 0, 1, and 2. At least one of r3 and r4 and/or r5 and r6 form a cyclic ring of 3-8 carbon atoms optionally containing alkyl groups, hetero atoms, or functional groups such as o, n, so2.
The invention relates to a composition in aqueous solution, including insulin and at least one substituted anionic compound chosen from substituted anionic compounds consisting of a backbone formed from a discrete number u of between 1 and 8 (1≦u≦8) of identical or different saccharide units, linked via identical or different glycoside bonds, said saccharide units being chosen from the group consisting of hexoses, in cyclic form or in open reduced form, said compound comprising partially substituted carboxyl functional groups, the unsubstituted carboxyl functional groups being salifiable. The invention also relates to a pharmaceutical formulation comprising a composition as claimed in any one of the preceding claims..
