Abstract: Certain novel compounds and derivatives thereof are agonists of the human melanocortin receptor(s) and, in particular, are selective agonists of the human melanocortin-4 receptor (MC-4R). They are therefore useful for the treatment, control, or prevention of diseases and disorders responsive to the activation of MC-4R, such as obesity, diabetes, sexual dysfunction, including erectile dysfunction and female sexual dysfunction.

Abstract: The present invention relates to methods of gene therapy for inhibiting angiogenesis associated with solid tumor growth, tumor metastasis, inflammation, psoriasis, rheumatoid arthritis, hemangiomas, diabetic retinopathy, angiofibromas, and macular degeneration Gene therapy methodology is disclosed for inhibition of primary tumor growth and metastasis by gene transfer of a nucleotide sequence encoding a soluble form of a VEGF tyrosine kinase receptor to a mammalian host. The transferred nucleotide sequence transcribes mRNA and a soluble receptor protein which binds to VEGF in extracellular regions adjacent to the primary tumor and vascular endothelial cells. Formation of a sVEGF-R/VEGF complex will prevent binding of VEGF to the KDR and FLT-1 tyrosine kinase receptors, antagonizing transduction of the normal intracellular signals associated with vascular endothelial cell-induced tumor angiogenesis.

Abstract: In accordance with the present invention, there are provided nucleic acids encoding human NMDA receptor protein subunits and the proteins encoded thereby. The NMDA receptor subunits of the invention comprise components of NMDA receptors that have cation-selective channels and bind glutamate and NMDA. In one aspect of the invention, the nucleic acids encode NMDAR1 and NMDAR2 subunits of human NMDA receptors. In a preferred embodiment, the invention nucleic acids encode NMDAR1, NMDAR2A, NMDAR2B, NMDAR2C and NMDAR2D subunits of human NMDA receptors. In addition to being useful for the production of NMDA receptor subunit proteins, these nucleic acids are also useful as probes, thus enabling those skilled in the art, without undue experimentation, to identify and isolate related human receptor subunits.
Abstract: The present invention relates to a novel vaccine formulation comprising nucleic acid molecules and an mineral-based adjuvant provided in a biologically effective concentration so as to improve induction of an immune response subsequent to vaccination which correlates to expression of one or more specific antigens encoded by the nucleic acid molecule.

Abstract: A process for preparing a &bgr;-hydroxy carbamate product is disclosed. The process comprises reacting an olefin compound containing at least one carbon-carbon double bond with a carbamate in an aqueous solvent and in the presence of a base, an osmium catalyst, a co-oxidant selected from a halohydantoin, a haloisocyanuric acid, and an alkali metal salt of a haloisocyanuric acid, and optionally an asymmetric ligand, to form a reaction mixture containing the &bgr;-hydroxy carbamate product. The process optionally further comprises treating the &bgr;-hydroxy carbamate product with additional base to form an oxazolidinone. The oxazolidinones are useful as chiral auxiliary agents and as intermediates for the formation of pharmaceutically active substances such as alpha 1 a adrenergic receptor antagonists. A process for preparing nitrogen-functionalized derivatives of the oxazolidinones is also disclosed.

Abstract: Automated measurement apparatus and methods for automated drug screening procedures are provided. The apparatus is capable of initiating and measuring rapid or transient events, such as cell receptor and/or ion channel activity. In particular, the apparatus is capable of aligning with predetermined positions, one or more samples contained in a multi-well container, initiating the reaction with reagent addition and measuring a resultant attribute for a period of time. The apparatus can substantially continuously measure and record data corresponding to the measured attribute before, during and after initiation of the reaction so that a time course of the rapid or transient event may be determined. After the reaction(s) are complete in one or more wells of the multi-well container, the apparatus can align one or more different wells to be assayed with the predetermined position and repeat the cycle until a predetermined number of wells are assayed.
