Embodiments of the invention provide derivatives of Amphotericin B having increased solubility and reduced toxicity relative to AMB, while retaining antifungal activity against multiple clinical fungal isolates. Derivatives of AMB are provided comprising a polymer group having an amine group, the polymer linked to mycosamine via a relatively stable linker such as an amide linker. The derivatives may be of the general formula [I]:
wherein R is H, C
1-4
alkyl or phenyl; R
2
is (CH
2
)
m
wherein m is between 0 and 4; R
3
and R
4
are each independently H or C
1-4
alkyl, R
5
is H or OH, R
6
is selected from a group consisting of: amide and alkyl, and R
7
is a water-soluble polymer, and pharmaceutically acceptable salts, solvates, hydrates, diastereomers, and prodrugs of the compound of Formula [I].
