1. A compound of formula I:

  • wherein;

    Q is (C1-C6)alkyl, (C6-C10)aryl, (C5-C10)heteroaryl, or (C6-C10)aryl-NH(C1-C6)alkyl;

    Y is O, S, NH, —

    X—

    C(═

    O)—

    , —

    C═

    N—

    , carbonyl, or —

    O—

    C(=Z)-X—

    ;

    Z is O or S;

    A is aryl, aryl(C1-C6)alkyl, heteroaryl, or a direct bond;

    X is O, NH, or S;

    V is C or N;

    M is H, an alkali metal, or tetra(C1-C20)alkylammonium;

    L is —

    X—

    C(=Z)-X—

    or a direct bond;

    R1 is (C4-C20)alkyl, (C2-C20)alkenyl, (C6-C16)aryl, (C5-C10)heteroaryl, (C1-C20)alkoxy(C1-C20)alkyl, (C1-C12)alkyl(C6-C20)polyalkoxy, or (C6-C20)(alkylthio)-(C1-C6)alkyl, or absent when V is N;

    R2 and R3 are each independently H or (C1-C20)alkyl;

    orR2 and R3 together form a 3-8 membered carbocycle ring, or a 3-8 membered heterocyclic ring comprising 1, 2, or 3 N(Rx), S, or O;

    or—

    V(R2)(R3)-L-R′

    is optionally —

    O—

    R1 when A is aryl;

    wherein any alkyl, alkenyl, aryl, or heteroaryl, carbocyclic ring, or heterocyclic ring, is optionally substituted with one or more (e.g., 1, 2, 3, 4, or

         5) (C1-C20)alkyl, (C2-C20)alkenyl, (C2-C10)alkynyl, (C3-C10)cycloalkyl, (C1-C20)alkoxy, (C1-C20)alkylcarbonyl, (C1-C20)alkylcarboxyl, halo, hydroxyl, —

    CO2Rx, —

    SO2Rx, —

    SO3Rx, nitro, amino, N(Rx)2, mercapto, (C1-C20)alkylthio, (C6-C16)aryl, (C6-C30)arylthio, trifluoromethyl, ═

    O, heteroaryl, or heterocycle groups;

    provided that Q is not substituted with CO2H; and

    each Rx is independently H, (C1-C6)alkyl, (C6-C16)aryl, or (C1-C6)alkyl-(C6-C16)aryl;

    or a salt thereof.
