摘要:
Novel biotinylated composition comprising a nucleic acid, e.g. siRNA, that are useful for targeting therapeutic and imaging agents to sites of infection and tumors are disclosed.
摘要:
This invention provides compositions and methods for enhancing delivery of drugs and other agents across epithelial tissues, including the skin, gastrointestinal tract, pulmonary epithelium, ocular tissues and the like. The compositions and methods are also useful for delivery across endothelial tissues, including the blood brain barrier. The compositions and methods employ a delivery enhancing transporter that has sufficient guanidino or amidino sidechain moieties to enhance delivery of a compound conjugated to the reagent across one or more layers of the tissue, compared to the non-conjugated compound. The delivery-enhancing polymers include, for example, poly-arginine molecules that are preferably between about 6 and 25 residues in length.
摘要:
The present invention relates to, inter alia, extracellular drug conjugates (EDC) in which an antibody or other targeting agent (e.g. a targeting moiety) is linked to a drug through a linker (e.g. a non-cleavable linker). These conjugates are useful in the treatment of disease and/or as a tool in the evaluation of biological systems.
摘要:
A conjugate molecule comprising an oligo- or polysaccharide covalently bound to a carrier and its use as potential vaccine against infection by S. Flexneri.
摘要:
Conjugated compounds comprising a therapeutic or diagnostic agent linked to a substrate for a cell membrane transporter or receptor by lipophilic linker are provided.
摘要:
A probe compound for protein tyrosine phosphatases (PTPs), as shown in Formula (I) is provided. In Formula (I), A1 and A2 represent amino acids. The amino acids include leucine, phenylalanine, glutamic acid, lysine, alanine, arginine, aspartic acid, asparagine, citrulline, cysteine, cystine, glutamine, glycine, histidine, hydroxyproline, isoleucine, methionine, proline, serine, threonine, tryptophan, valine or a combination thereof. The invention also provides probe compound precursors for protein tyrosine phosphatases (PTPs).
摘要:
In certain embodiments, this present invention provides antibodies and Fc fusion proteins with enhanced pharmacokinetics, such as biotinylated antibodies or biotinylated Fc fusion polypeptides.
摘要:
Disclosed are polar, hydrophilic stimulant prodrug compositions comprising at least one stimulant chemically attached to a polar hydrophilic ligand, a salt thereof, a derivative thereof, or a combination thereof. Methods of making and using the same are also disclosed.
摘要:
The invention relates to a method of selectively targeting an active agent (or agent capable of becoming an active agent) to apoptotic cells in a vertebrate, comprising administering to said vertebrate a system comprising an arsenoxide (or arsenoxide equivalent) compound and said agent, wherein said system selectively targets apoptotic cells.
