Abstract: The present invention relates to a method of treating agitation in a human patient with dementia, comprising administering to the human patient with dementia in need thereof a pharmaceutically effective amount of a compound of formula (I) or a pharmaceutically acceptable salt or hydrate thereof to treat agitation, wherein R1-R4 are defined herein: wherein the human patient has at least an about 20% reduction in their symptom of agitation, relative to the patient prior to administration of the compound of formula (I).

Abstract: Patients suffering from serotonin-mediated diseases or conditions, such as depression, may be treated by administering an effective combined amount of a 5-HT7 receptor antagonist and a serotonin reuptake inhibitor.

Abstract: The invention provides novel non-peptidic NPY Y2 receptor inhibitors useful in treating or preventing: anxiolytic disorders or depression; injured mammalian nerve tissue; conditions responsive to treatment through administration of a neurotrophic factor; neurological disorders; bone loss; substance related disorders; sleep/wake disorders; cardiovascular disease; obesity; or an obesity-related disorder. Compounds of the invention are also useful in modulating endocrine functions, particularly endocrine functions controlled by the pituitary and hypothalamic glands, and are therefore useful in the treatment or prevention of inovulation and infertility.

Abstract: Chimeric polypeptides of relaxin-3, prepropolypeptides thereof, polynucleotides encoding such polypeptides, and associated expression vectors and host cells are described. The polypeptides may be used to prepare receptor-ligand complexes with GPCR135 or GPCR142, which may be used in assay methods.

Abstract: Canine 5-hydroxytryptamine 2 receptor materials are described, including polypeptides corresponding to SEQ ID NOs.:8 and 10 and polynucleotides expressing them corresponding to SEQ ID NOs.:7 and 9. Such materials are useful as reagents in drug screening assays to identify compounds having 5-HT2 receptor-modulating activity.

Abstract: Implementing gene expression to study drug action in the central nervous system is complicated by functional heterogeneity because of the existence of many different neuronal subtypes within the mammalian brain. The integration of laser capture microdissection (LCM) and RNA amplification with cDNA microarray technology allows for large-scale gene expression analysis at cellular level. Using this approach, we have generated gene expression profiles of imipramine, a reference antidepressant, and a new putative antidepressant, novelR1 in several laser-captured brain nuclei (locus coeruleus, dorsal raphe, hypothalamic paraventricular nucleus and hippocampus) of rats subjected to the chronic mild stress model (CMS) of depression.
