摘要:
Agents and methods for imaging a cell and/or a portion of tissue characterized by fibrosis, as well as to agents and methods for determining and/or diagnosing fibrotic diseases are disclosed herein. Also disclosed herein are polymer conjugates that can include a detectable label, a retinoid and a polymer. The polymer conjugates can be used to image a portion of tissue, deliver a detectable label to a portion of tissue or a cell and/or diagnosis a condition or disease.
摘要:
Polymers and methods of making them are described. The polymers may be used to coat living cells. The polymer-coated cells are useful in cell therapy applications.
摘要:
Methods for preparing and isolating polymer conjugates that include a recurring unit of Formulae (I) and (Ia) are described herein. The polymer conjugates can include an anti-cancer drug.
摘要:
Various biocompatible polymers having platinum compounds conjugated thereto are prepared. Such polymers are useful for a variety of drug, biomolecule, and imaging agent delivery applications. Also disclosed are methods of using the polymers to treat, diagnose, and/or image a subject.
摘要:
Complexes are disclosed which are a combination of a polynucleotide and a biodegradable polyacetal-peptide. The disclosed complexes are useful for cell transfection.
摘要:
A microscope system, kit and method are described for observation of cellular activity in real time. The system is used to monitor cell transfection using a polynucleotide noncovalently attached to a carrier, The carrier labeled with a dye or fluorescent agent so that transport of complex can be monitored in real time. The polynucleotide includes both a gene of interest and a reporter gene. The reporter gene indicates successful expression of the gene of interest.
摘要:
Polyacetals comprising a recurring units represented by a formula selected from the group consisting of formula (I) and (II): wherein A comprises at least one acetal group; B is selected from the group consisting of —CH—, —CH(CH3)—, CH2CH—, —CH2C(CH3)—, —CH(CH3)CH—, and —CHCH(CH3)CH(CH3)—; Z is selected from the group consisting of C(O)OR1, C(O)SR1, C(O)NR1R2, and VU; V is a linker group; U is selected from the group consisting of poly(ethyleneimine), poly(propyleneimine), poly(lysine), PAMAM dendrimer, octaamine dendrimer, hexadecaamine dendrimer, enhancer, and targeting receptor; R1 and R2 are each individually selected from the group consisting of hydrogen, C1 to C10 alkyl, and C6 to C10 aryl; D is a linkage selected from the group consisting of carboxylic amide, carboxylic ester, urea, and urethane; and G is selected from the group consisting of C4 to C20 alkyl, C6-C10 aryl, and —(OCH2CH2)n—, where n is in the range of 1 to about 250, are useful in nucleic acid delivery applications. In preferred embodiments, complexes formed between polyacetals of the formulae (I) or (II) and polynucleotides are useful as transfection reagents.
