Abstract: The present invention relates to optionally substituted, non-toxic peptides and derivatives capable of inhibiting superoxide production in phagocytic cells. The invention also relates to compositions and methods useful in inhibiting inflammation and in treating inflammatory disorders such as autoimmune disorders, gout, adult respiratory distress syndrome, asthma, myocardial infarction, and various dermatological disorders. The present invention contemplates compositions derived from low molecular weight GTP-binding proteins (LMWG), mastoparan, GAP proteins, and related peptides. The invention further contemplates compositions useful in inhibiting activation of NADPH oxidase or in promoting GDP/GTP exchange. Therapeutic compositions containing various inhibitors, and methods of using same, are also disclosed.

Abstract: Modified pyrimidine nucleotides derivatized at C5 to contain a functional group that mimics the property of a naturally occurring amino acid residues are provided. DNA molecules containing the modified nucleotides are also provided.

Abstract: Zinc finger-nucleotide binding polypeptides having binding specificity for target nucleotides containing one or GNN triplets are provided. Compositions containing such polypeptides and the use of such polypeptides and compositions for regulating nucleotide function are also provided.

Abstract: The present invention discloses catalytic or enzymatic DNA molecules that contain a modified nucleotide and that are capable of cleaving nucleic acid sequences or molecules, particularly RNA, in a site-specific manner, as well as compositions including same. Methods of making and using the disclosed enzymes and compositions are also disclosed.

Abstract: The present invention describes methods for producing antibody libraries, and particularly for increasing antibody library diversity by inducing mutagenesis within the CDR regions of immunoglobulin heavy or light chains that are displayed on the surface of filamentous phage particles comprising the library. The invention also describes oligonucleotides useful for increasing the library diversity, and universal light chains useful in the library production methods.

Abstract: The present invention describes an encoded combinatorial chemical library comprised of a plurality of bifunctional molecules having both a chemical polymer and an identifier oligonucleotide sequence that defines the structure of the chemical polymer. Also described are the bifunctional molecules of the library, and methods of using the library to identify chemical structures within the library that bind to biologically active molecules in preselected binding interactions.

Abstract: The present invention describes polypeptides and anti-peptide antibodies capable of inhibiting serine protease enzymatic activity. In particular, polypeptides and anti-peptide antibodies derived from the blood coagulation serine proteases Factor VIIa, Factor IXa, Factor Xa, Factor XIa, thrombin and plasma kallikrein are described that are capable of inhibiting coagulation. The polypeptide and antibody are useful in methods and systems for inhibiting serine proteases, and particularly for inhibiting blood coagulation processes mediated by serine proteases in vitro or in a human patient.

Abstract: This invention features methods of synthesizing combinatorial libraries of chemical compounds, and combinatorial libraries of chemical compounds formed by the methods of this invention. Specifically, Diels-Alder chemistry is utilized to generate libraries of diverse molecules which are easily differentially functionalized with various chemical moities and in one aspect are configured to act as non-hydrolyzable peptidomimetics.
