Matrix metalloproteinase inhibitors and method of using same

Conformationally restricted polyamines

Peptoid compounds of Formula I and Formula II are disclosed

Novel 4-substituted-1,2-naphthoquinones, pharmaceutical unit dosage forms containing 4-substituted-1,2-naphthoquinones, and uses of 4-substituted-1,2-naphthoquinones to inhibit the growth of cancer cells are disclosed.

4-substituted-1, 2-naphthoquinones and their use in the inhibition of

A method for identifying patients at risk of developing vascular leakage syndrome and systemic inflammatory response syndrome (SIRS) such as septic shock by determining the serum levels of metalloproteinase expression, in particular type IV collagenase expression, as well as a method of treating or preventing vascular leakage syndrome and SIRS by the administration of one or more metalloproteinase inhibitors, preferably type IV collagenase inhibitors is taught. Additionally, the therapeutic efficacy of bis(dioxopiperazine) compounds is determined on the basis of collagenase inhibiting activity, and the compounds which inhibit collagenase activity are utilized for the treatment of collagenase related disorders, e.g., vascular leakage syndrome, septic shock, stroke, cardiac disorders, angiogenesis, and arthritis. Finally, a method for preventing or treating toxicity caused by endogenous cytokine expression or cytokine administration or by immunotoxin administration by the administration of one or more metalloproteinase inhibitors, preferably type IV collagenase inhibitors is taught.

Treatment of vascular leakage and related syndrome such as septic shock

The invention relates to .beta.-lapachone derivatives of formula II and compositions containing said compounds: ##STR1## wherein, R.sup.5, R.sup.6 and R.sup.7 are as defined in the specification. The compounds are potent inhibitors of neoplastic cell growth and proliferation.

Ortho-quinone derivatives novel synthesis therefor and their use in the

3-Substituted-.beta.-lapachone analogs and their use either alone or to augment chemotherapy or radiotherapy to induce programmed neoplastic cell death without exhibiting toxicity to surrounding normal cells are disclosed. In particular, 3-allyl-.beta.-lapachones, 3-alkyl-.beta.-lapachones and 3-halo-.beta.-lapachones were found to be Topoisomerase (Topo I) inhibitors. When these analogs are used alone there is a reversible single-strand break in the DNA of neoplastic cells causing apoptosis and cell death in some cells. However, when these analogs are combined with chemotherapy or X-irradiation, an irreversible Topo I-mediated break is achieved. A new and more efficient chemical synthesis of the compounds is also disclosed.

The invention further relates to the use of such optically pure compounds as potent inhibitors of platelet aggregation by working at the level of cyclooxygenase. the invention further relates to the pharmaceutical use of such compounds in the treatment of coronary artery diseases, especially in the treatment and/or prevention of atherosclerosis.

Synthesis of optically pure 4-aryl-2-hydroxytetronic acids

One aspect of the present invention relates to a process of making cyclohexane-1,2-di(O)-4,5-di(N) diastereomers which are useful as a synthons for various diastereoisomeric pharmaceutical systems. The present invention also relates to the stereoisomer compounds which are derived from retro- synthetic analysis. In another aspect, the present invention relates to novel antineoplasic Pt(II) complexes derived from the stereoisomers and the processes for making such Pt(II) complexes. Mono- and di-hydroxyl substitution on the cyclohexane ring renders the organoplatinum complex relatively more water soluble, thereby facilitating intravenous administration. The Pt(II) complexes of the present invention are less nephrotoxic than cisplatin and are readily excreted via the kidney due to their enhanced water solubility. In a composition aspect, the present invention encompasses novel pharmaceutical compositions comprising the novel Pt(II) complexes in an amount sufficient to have an antineoplastic effect in an animal or patient.

The present invention relates to a method for synthesis of optically pure stereogenically labile 4-substituted-2-hydroxytetronic acids from an asymmetric .alpha.-hydroxy ester. The chiron approach of the present invention utilizes a non-nucleophilic lithium amide base under kinetically controlled Claisen conditions to produce a 4-substituted-2-pheylmethoxy precursor to the 4-substituted-2-hydroxy tetronic acid. The invention further relates to the use of such optically pure compounds as potent inhibitors of platelet aggregation by working at the level of cyclooxygenase. The invention further relates to the pharmaceutical use of such compounds in the treatment of coronary artery diseases, especially in the treatment and/or prevention of atherosclerosis.
