摘要:
A polymeric prodrug composition including a hydrogel, a biologically active moiety and a reversible prodrug linker. The prodrug linker covalently links the hydrogel and the biologically active moiety at a position and the hydrogel has a plurality of pores with openings on its surface. The diameter of the pores is larger than that of the biologically active moiety at least at all points of the pore between at least one of the openings and the position of the biologically active moiety.

摘要:
The present invention provides methods and compositions for the treatment of ion imbalances. In particular, the invention provides core-shell compositions and pharmaceutical compositions thereof. Methods of use of the core-shell compositions for therapeutic and/or prophylactic benefits are disclosed herein. Examples of these methods include the treatment of phosphate imbalance disorders, hypertension, chronic heart failure, end stage renal disease, liver cirrhosis, chronic renal insufficiency, fluid overload, or sodium overload.
摘要:
The invention provides a method of treating a wound (for example, a chronic ulcerous skin lesion) in a human or non-human mammal (particularly a human). The wound is contacted with a topical hydrogel composition comprising a hydrophilic polymer carrying multiple pendant sulphonyl groups, optionally with multiple pendant carboxylic groups, on each polymer molecule.
摘要:
Antibiotic-associated diarrhea, such as that caused by Clostridium difficile, represents a serious medical complication that can result from administering a broad-spectrum antibiotic to a subject. Such diarrhea leads to significant potassium loss from the subject. The present invention discloses a polymeric therapeutic agent that treats antibiotic-associated diarrhea and is physiologically potassium neutral. This polymer contains polystyrene sodium sulfonate and polystyrene potassium sulfonate repeat units.
摘要:
The present invention relates to a method for removing bile acids from a patient and certain polymers of use in the method. The method comprises the step of administering to the patient a therapeutically effective amount of a polymer composition which includes a a poly(diallylamine) polymer which is substituted with hydrophobic groups. The hydrophobic groups can be a substituted or unsubstituted, straight chain or branched C3–C24-alkyl group, an aralkyl group or an aryl group.
摘要:
The disclosure provides compositions and methods for blocking the proteasome pathway, as well as compounds that block mitotic cell cycle progression. Compounds disclosed include a family of molecules that bind to a multiubiquitin chain attached to a protein and thereby inhibit degradation of that protein by the proteasome pathway. According to another aspect of the disclosure, compounds are provided that inhibit cell cycle progression. Compounds disclosed herein may be formulated for pharmaceutical use and employed in methods for treating cancers or other hyperproliferative disorders.
摘要:
Methods are provided for enhancing the permeability of skin or mucosal tissue to topical or transdermal application of pharmacologically or cosmeceutically active agents. The methods entail the use of a base in order to increase the flux of the active agent through a body surface while minimizing the likelihood of skin damage, irritation or sensitization. The permeation enhancer can be an inorganic or organic base. Compositions and transdermal systems are also described.
