摘要:
The present invention provides modified amino acids for delivering active agents, and particularly biologically or chemically active agents. The preferred modified amino acids of the present invention include N-acylated or sulfonated amino acids. These modified amino acids are used as carriers to facilitate the delivery of a cargo to a target. Such modified amino acids are well suited to form non-covalent mixtures with biologically-active agents for oral administration to animals. Methods for the preparation and administration of the modified amino acids and compositions including the same are also provided.
摘要:
Novel compounds are described. The compounds generally comprise an acidic group, a basic group, a substituted amino or N-acyl and a group having an optionally hydroxylated alkane moiety. Pharmaceutical compositions comprising the inhibitors of the invention are also described. Methods of inhibiting neuraminidase in samples suspected of containing neuraminidase are also described. Antigenic materials, polymers, antibodies, conjugates of the compounds of the invention with labels, and assay methods for detecting neuraminidase activity are also described.
摘要:
Carrier compounds, compositions, and dosage unit forms therefor which are useful in the delivery of active agents are provided. The present invention provides a compound having the formula: ##STR1## or a salt thereof, wherein the compound may be used in a composition or dosage unit form for delivery of at least one active agent, including a peptide, mucopolysaccharide, carbohydrate, or a lipid. Methods of administration and preparation of the compounds and compositions of the invention are provided as well, including oral administration. Further, the compositions of the invention may be prepared by mixing at least one active agent, at least one carrier compound, and, optionally, a dosing vehicle.
