Abstract: Disclosed are compounds of formulas (I) and (III) for treating or preventing a disease or disorder responsive to activation of a D1 dopamine receptor agonist in a mammal in need thereof, wherein m, n, R1-R6, and R11-R13 are as defined herein. Examples of such disease or disorder include Alzheimer's Disease, schizophrenia, Parkinson's disease, a dyskinesia, and Huntington's disease.

Abstract: Genes encoding the St-B17 serotonin receptor protein were cloned and characterized from a rat striatum mRNA and a human genomic library. The St-B17 receptor has nucleotide and amino acid homology with previously described 5-HT genes and can bind ligands that are known to interact with serotonin receptors. In addition, the levels of intracellular cAMP in cells transfected with the receptor gene respond in a dose dependent manner to introduction of serotonin in the media.

Abstract: The present invention relates to the molecular cloning and expression of the D.sub.1 dopamine receptor protein that is linked to the activation of adenylyl cyclase activity. By constructing cell lines that express the D.sub.1 receptor, the affinities and efficacies of agonist and antagonist drugs with the receptor can be assessed.The present invention further relates to a recombinant DNA construct that includes a vector and a DNA fragment encoding the D.sub.1 receptor. The present invention also relates to a host cell transformed with a recombinant DNA construct, so that the DNA fragment is expressed and the D.sub.1 receptor is produced. Suitable expression systems include eukaryotic and procaryotic cells, especially mammalian cells such as rat or human.The present invention further relates to the antibody to the D.sub.1 receptor protein. For diagnostic purposes, antibodies to this receptor can be prepared by producing all or a portion of the receptor protein and injecting these into various types of mammals.

Abstract: In the present investigation, we report the identification and cloning of a cDNA encoding an RNA splice variant of the rat D.sub.2 receptor CDNA.sup.12. This cDNA codes for a receptor isoform which is predominantly expressed in the brain and contains an additional 29 amino acids in the 3rd cytoplasmic loop, a region believed to be involved with G protein coupling. This is the first example of a novel G-protein coupled receptor isoform generated by alternative RNA splicing.
