Abstract:
The synthesis of new a-helix scaffolds mimicking i, i+3 or i+4, i+7 residues, was accomplished. The common pyridazine heterocycle originates from the easily available dimethyl pyridazine-3,6-dicarboxylate building block. These scaffolds may be thought of as synthetic counterparts of amphiphilic a-helices having a hydrophilic face along one side and a hydrophobic face along the other side of the helix.

Abstract:
The invention relates to orthogonal pairs of tRNAs and aminoacyl-tRNA synthetases that can incorporate unnatural amino acids that comprise a 1,2 aminothiol group into polypeptides. The invention provides translation systems in which polypeptides comprising unnatural amino acids that comprise a 1,2 aminothiol group can be produced. The invention also provides methods for producing polypeptides containing unnatural amino acids that comprise a 1,2 aminothiol group. Also provided by the invention are compositions comprising orthogonal aminoacyl-tRNA synthetases that preferentially aminoacylate a cognate orthogonal tRNA with unnatural amino acids that comprise a 1,2 aminothiol group. The invention provides methods for the synthesis of the unnatural amino acid 2-amino-3 -(4-(2-amino-3 -mercaptopropan-amido)phenyl)-propanoic acid.
Abstract:

Abstract:
The invention relates to the three-dimensional structure of a crystal of an EphB4 receptor complexed with a ligand. The three-dimensional structure of a Receptor-Ligand Complex is disclosed. The receptor-ligand crystal structure, wherein the ligand is an inhibitor molecule, is useful for providing structural information that may be integrated into drug screening and drug design processes. Thus, the invention also relates to methods for utilizing the crystal structure of the Receptor-Ligand Complex for identifying, designing, selecting, or testing inhibitors of the EphB4 receptor protein, such inhibitors being useful as therapeutics for the treatment or modulation of i) diseases; ii) disease symptoms; or iii) the effect of other physiological events mediated by the receptor.
Abstract:
The invention relates to the three-dimensional structure of a crystal of a transporter protein complexed with a ligand. The three-dimensional structure of the transporter-ligand complex is disclosed. The transporter-ligand crystal structure, wherein the ligand is an inhibitor molecule, is useful for providing structural information that may be integrated into drug screening and drug design processes. Thus, the invention also relates to methods for utilizing the crystal structure of the transporter-ligand complex for identifying, designing, selecting, or testing inhibitors of the transporter protein, such inhibitors being useful as therapeutics for the treatment or modulation of i) diseases; ii) disease symptoms; or iii) the effect of other physiological events mediated by the transporter.
Abstract:

Abstract:
Variants (mutants) of recombinant activated protein C (APC) or recombinant protein C (prodrug, capable of being converted to APC) that have substantial reductions in anticoagulant activity but that retain normal levels of anti-apoptotic activity are provided. Three examples of such recombinant APC mutants are KKK191-193AAA-APC, RR229/230AA-APC, and RR229/230AA plus KKK191-193AAA-APC. APC variants and prodrugs of the invention have the desirable property of being cytoprotective (anti-apoptotic effects), while having significantly reduced risk of bleeding. The invention also provides a method of using the APC variants or prodrugs of the invention to treat subjects who will benefit from APC's cytoprotective activities that are independent of APC's anticoagulant activity. These subjects include patients at risk of damage to blood vessels or tissue in various organs caused, at least in part, by apoptosis. At risk patients include, for example, those suffering (severe) sepsis, ischemia/reperfusion injury, ischemic stroke, acute myocardial infarction, acute or chronic neurodegenerative diseases, or those undergoing organ transplantation or chemotherapy, among other conditions. Methods of screening for variants of recombinant protein C or APC that are useful in accordance with the invention are also provided.
