  • Patent number: 8137700
    Abstract: Novel main chain acid degradable polymer backbones and drug delivery systems comprised of materials capable of delivering bioactive materials to cells for use as vaccines or other therapeutic agents are described. The polymers are synthesized using monomers that contain acid-degradable linkages cleavable under mild acidic conditions. The main chain of the resulting polymers readily degrade into many small molecules at low pH, but remain relatively stable and intact at physiological pH. The new materials have the common characteristic of being able to degrade by acid hydrolysis under conditions commonly found within the endosomal or lysosomal compartments of cells thereby releasing their payload within the cell. The materials can also be used for the delivery of therapeutics to the acidic regions of tumors and other sites of inflammation.

The bisimides provided by the present invention are prepared either by reaction of a diamine such as 4,4?-diaminodiphenylsulfone (DDS) with an anhydride, for example 3-chlorophthalic anhydride (3-ClPA) in the presence of a solvent at a pressure greater than one atmosphere and at a temperature above the normal boiling point of the solvent, or by reaction of a monoamine with a dianhydride under the same conditions. In one embodiment, the relatively insoluble product bisimides provided by the present invention have a solubility in ortho-dichlorobenzene of less than about 10 percent by weight at a temperature of about 180° C.

  • Patent number: 7977445
    Abstract: Aqueous, storage-stable emulsions of ?-silyl terminated polymers are useful as adhesives, sealing compounds and coating materials. The ?-silyl terminated polymers correspond to the general formula (I): in which R1 is a linear or branched alkyl or alkoxy group containing 1 to 4 carbon atoms, R2 and R3 independently of one another are linear or branched alkyl groups containing 1 to 4 carbon atoms, R4 and R6 independently of one another are divalent organic connecting groups, R5 is a hydrophobic divalent polymer group; and R7 is a CH2SiR1(OR2)(OR3) group, in which R1, R2 and R3 have the above meaning or R7 stands for a group that lends the polymer of the general formula (I) the property of self-emulsification in water by forming an oil in water emulsion.

  • Patent number: 7977452
    Abstract: This invention provides a cost effective process and new Janus dendrimers where at least two dendrons are attached at the core (with or without a connector group) and where at least two of the dendrons have different functionality. Preferred are those Janus dendrimers where at least one dendron is a PEHAM dendron. Thus these Janus dendrimers are heterobifunctional in character and use unique ligation chemistry with single site functional dendrons, di-dendrons and multi-dendrons. Also included are Janus dendrons which may be used as intermediates to make the Janus dendrimers or to further react with another reactive moiety.

    Abstract: The present invention relates to biodegradable biocompatible polyketals, methods for their preparation, and methods for treating animals by administration of biodegradable biocompatible polyketals. In one aspect, a method for forming the biodegradable biocompatible polyketals comprises combining a glycol-specific oxidizing agent with a polysaccharide to form an aldehyde intermediate, which is combined with a reducing agent to form the biodegradable biocompatible polyketal. The resultant biodegradable biocompatible polyketals can be chemically modified to incorporate additional hydrophilic moieties. A method for treating animals includes the administration of the biodegradable biocompatible polyketal in which biologically active compounds or diagnostic labels can be disposed. The present invention also relates to chiral polyketals, methods for their preparation, and methods for use in chromatographic applications, specifically in chiral separations.
