  • Patent number: 6331563
    Abstract: Matrix metalloproteinases (MMPs) are a group of enzymes that have been implicated in the pathological destruction of connective tissue and basement membranes. These zinc containing endopeptidases consist of several subsets of enzymes including collagenases, stromelysins and gelatinases. TNF-&agr; converting enzyme (TACE), a pro-inflammatory cytokine, catalyzes the formation of TNF-&agr; from membrane bound TNF-&agr; precursor protein. It is expected that small molecule inhibitors of MMPs and TACE therefore have the potential for treating a variety of disease states.

  • Patent number: 6245804
    Abstract: This invention describes the new, nonsteroidal gestagens of general formula I in which A, B, Ar, R1, R2 and R3 have the meanings that are indicated in more detail in the description. The new compounds show a very great affinity to the gestagen receptor. They can be used alone or in combination with estrogens in contraceptive preparations. In addition, they can be used for treating endometriosis. Together with estrogens, they can also be used in preparations for treating gynecological disorders, for treating premenstrual symptoms and for substitution therapy. Based on the androgenic action, they can also be used for male birth control, male HRT and hormone therapy and for treating andrological disease agents.
