摘要:
The invention relates to compositions which are useful for inhibiting ribonucleotide reductase enzymes, including the mammalian ribonucleotide reductase enzyme. The compositions include, but are not limited to, linear peptides, cyclic peptides, peptide analogs, and peptidomimetics. Methods of using the compositions of the invention to treat cancer and viral and bacterial infections are disclosed.
摘要:
Triene-containing compounds which mimic the chemical and/or biological activity of the spongistatins are provided, as are methods and intermediates useful in their preparation.
摘要:
Novel .alpha.-aminophosphonates are provided along with processes and intermediates for their preparation. In preferred embodiments, scalemic .alpha.-aminophosphonates are prepared by the stereoselective addition of phosphite salts to chiral imines.
摘要:
The invention provides oleocanthal analogs and methods of using oleocanthals in various formulations including, food additives; pharmaceuticals; cosmetics; animal repellants; and discovery tools for mammalian irritation receptor genes, gene products, alleles, splice variants, alternate transcripts and the like.
摘要:
6- and 7-substituted coumarin and related 6- and 7-substituted 1H-quinolin-2-one compounds, pharmaceutical compositions containing these compounds, and methods for their pharmaceutical use are disclosed. In certain embodiments, the 7-substituted coumarin and related 7-substituted 1H-quinolin-2-one compounds mimic or exceed the high level of pharmacological activity of discodermolide. In other embodiments, their preparation involves more readily available materials, higher yield processes and/or simpler synthetic sequences. In yet other embodiments, the compounds of the invention represent structurally simpler, therapeutically active analogues of discodermolide than heretofore known and may be useful as microtubule stabilizers and, inter alia, for treating and/or preventing cancer and other diseases, disorders, and/or conditions mediated by the stabilization of microtubules.

摘要:
Novel macrolactone compounds, their methods of preparation, pharmaceutical compositions containing these compounds, and methods for their pharmaceutical use are disclosed. In certain embodiments, the macrolactone compounds may be useful, inter alia, for treating various cancers, inducing apoptosis in malignant cells, or inhibiting cancer cell division.
摘要:
Synthetic methods and intermediates useful in the preparation of lactone containing compounds such as discodermolide and compounds which mimic the chemical or biological activity of discodermolide are provided.
摘要:
The invention provides a new process for the preparation of polypyrrolinones (I) of various sizes which have found to be useful peptidomimetics. One aspect of the invention is a new process utilizing α-amino-α-substituted-valerolactones as synthons. A second aspect of the invention is a process for the synthesis of polypyrrolinones using solid-phase techniques.
