    摘要: The present invention provides pradimicin analogs of formula (II) which exhibit improved water solubility relative to parent compounds. These novel agents are useful in treatment of fungal infections.
    wherein R¹ is selected from the group consisting of H, methyl, and hydroxymethyl, and when R¹ is methyl or hydroxymethyl, the resulting amino acid has the D -configuration;
    R² is H or β-D-xylosyl;
    R³ is H or methyl; and
    R⁴ is selected from the group consisting of (C₂₋₅)alkenyl; (C₂₋₅)alkynyl; substituted (C₁₋₅)alkyl; substituted (C₂₋₅)alkenyl; wherein the substituent for both the alkyl and alkenyl is a group selected from the group consisting of, carboxy, (C₁₋₅)alkoxycarbonyl, carbamyl, (C₁₋₅)alkylcarbamyl, di(C₁₋₅)alkylcarbamyl, and sulfonyl; (C₁₋₅)alkanoyl substituted with a group selected from the group consisting of amino, (C₁₋₅)alkylamino, and di(C₁₋₅)alkylamino; L-glutamyl; formyl; benzyl; and p-tolylsulfonylcarbamyl; or
    a pharmaceutically acceptable salt thereof.
