  • Patent number: 6890937
    Abstract: A treatment process is disclosed that comprises administering an effective amount of an aromatic sulfone hydroxamic acid that exhibits excellent inhibitory activity of one or more matrix metalloprotease (MMP) enzymes, such as MMP-2, MMP-9, and MMP-13, while exhibiting substantially less inhibition at least of MMP-1 to a host having a condition associated with pathological matrix metalloprotease activity. The administered enzyme inhibitor corresponds in structure to formula (I), below, or a pharmaceutically acceptable salt thereof, wherein R1 and R2 are both hydrido or R1 and R2 together with the atoms to which they are bonded form a 5- to 8-membered ring containing one, two, or three heteroatoms in the ring that are oxygen, sulfur, or nitrogen. R3 in formula (I) is an optionally substituted aryl or optionally substituted heteroaryl radical.

  • Publication number: 20040209914
    Abstract: This invention is directed to aromatic sulfone hydroxamates (also known as aromatic sulfone hydroxamic acids) and salts thereof that, inter alia, tend to inhibit matrix metalloproteinase (also known as matrix metalloprotease or MMP) activity and/or aggrecanase activity. This invention also is directed to a treatment method that comprises administering such a compound or salt in an MMP-inhibiting and/or aggrecanase-inhibiting effective amount to an animal, particularly a mammal having (or disposed to having) a pathological condition associated with MMP activity and/or aggrecanase activity.

  • Patent number: 6583299
    Abstract: A family of molecules is disclosed that inhibit matrix metalloprotease (MMP) activity, and particularly inhibit the activity of one or more of MMP-2, MMP-9, or MMP-13, while generally exhibiting little activity against MMP-1. A contemplated compound also exhibits little inhibition of the production of TNF. A contemplated compound is an &agr;-amino-&bgr;-sulfonyl carbocyclo, heterocyclo, aryl, or heteroaryl hydroxamic acid. Also disclosed are processes for preparing a contemplated compound and for treating a mammal having a condition associated with pathological matrix metalloprotease activity.
