1. A method for treating a mammal having a disease characterized by an overproduction or an unregulated production of TNF-α

  • , comprising administering to the mammal a composition comprising an effective amount of a biologically active compound of the formula;

    wherein;

    X is hydroxamic acid, phosphoryl or carboxyl;

    m is 0, 1 or 2;

    R1, R2 and R3 each independent of the other is hydrogen, alkylene(cycloalkyl), OR4, SR4, N(R4)(R5), halogen, substituted or unsubstituted C1 to C8 alkyl, C1 to C8 alkylenearyl, aryl, a protected or unprotected side chain of a naturally occurring α

    -amino acid;

    or the group --R6 R7, wherein R6 is C1 to C8 alkyl and R7 is OR4, SR4, N(R4)(R5) or halogen, wherein R4 and R5 are each, independent of the other, hydrogen or substituted or unsubstituted C1 to C8 alkyl;

    n is 1 or 2;

    Y is hydrogen, unsubstituted or substituted C1 to C8 alkyl, alkylene(cycloalkyl), the group --R8 --COOR9 or the group --R10 N(R11)(R12);

    wherein R8 is C1 to C8 alkylene;

    R9 is hydrogen or C1 to C8 alkyl;

    R10 is C1 to C8 alkylene; and

    R11 and R12 are each, independent of the other, hydrogen or unsubstituted or substituted C1 to C8 alkyl;

    provided that when n is 1, A is a protected or an unprotected α

    -amino acid radical; and

    when n is 2, A is the same or different protected or unprotected α

    -amino acid radical; and

    when n is 2, A is the same or different protected or unprotected α

    -amino acid radical; and

    the pharmaceutically acceptable salts thereof;

    wherein the compound is capable of reducing serum TNF-α

    levels by at least 80% when administered at 25 mg/kg in a murine model of LPS-induced sepsis syndrome;

    and a pharmaceutically acceptable carrier.
