The biological activity of a set of structurally related aminopyrrolicsyntheticreceptors for monosaccharides has been tested versusyeast and yeast‐like microorganisms and compared to their binding affinity toward mannosides. Antibioticactivity comparable to that of well‐known polyene (amphotericin B) or azole (ketoconazole) drugs has been found for some members of the family, along with a general
The present invention relates generally to branched macromolecules bearing functional moieties. In particular, the invention relates to dendrimers, derived from lysine or lysine analogues, bearing a plurality of functional moieties. The invention further relates to the use of such macromolecules, particularly in therapeutic applications, and compositions comprising them.

The following invention is directed to macromolecules having controlled stoichiometry and topology, processes for their production, and applications for their use. The macromolecules have a controlled functional moiety stoichiometry and include at least one dendritic motif having a surface layer formed from at least one surface building unit and at least one subsurface layer formed from at least one building unit, the surface building unit and building units having a hydrocarbon backbone bearing a carbonyl group and at least one amine group; and at least two different functional moieties on the building unit and/or surface building unit; where functional moiety stoichiometry refers to the number and type of functional moieties.
The present invention provides a novel class of macrocyclic compounds as well as complexes formed between a metal (e.g., lanthanide) ion and the compounds of the invention. Preferred complexes exhibit high stability as well as high quantum yields of lanthanide ion luminescence in aqueous media without the need for secondary activating agents. Preferred compounds incorporate hydroxy-isophthalamide moieties within their macrocyclic structure and are characterized by surprisingly low, non-specific binding to a variety of polypeptides such as antibodies and proteins as well as high kinetic stability. These characteristics distinguish them from known, open-structured ligands.
