Xanomeline is an M(1)/M(4) preferring muscarinic receptor agonist which decreased psychotic behaviors in patients with Alzheimer's disease, suggesting that xanomeline might be useful in the treatment of psychotic symptoms in patients with schizophrenia. The purpose of the present studies was, therefore, to compare the pharmacologic profile of xanomeline(More)
Activation of muscarinic m1 receptors which are coupled to the phosphoinositide (PI) second messenger transduction system is the initial objective of cholinergic replacement therapy in Alzheimer's disease. Thus, we evaluated the ability of the selective muscarinic receptor agonist (SMRA) xanomeline to stimulate in vivo phosphoinositide (PI) hydrolysis and(More)
(5R,6R)-6-(3-butylthio-1,2,5-thiadiazol-4-yl)-1-azabicyclo[3.2.1]octane) (BuTAC) is a novel, selective muscarinic receptor ligand with partial agonist mode of action at muscarinic M2 and M4 and antagonist mode of action at M1, M3 and M5 receptor subtypes in cloned cell lines. BuTAC exhibits functional dopamine receptor antagonism despite its lack of(More)
Peroxisome proliferator-activated receptor (PPAR)-alpha controls the transcription of a variety of genes involved in lipid metabolism and is the target receptor for the hypolipidemic drug class of fibrates. In the present study, the molecular and physiological effects of seven different PPAR-activating drugs have been examined in a rodent model of(More)
Complementary DNA (cDNA) encoding human beta-amyloid precursor protein familial Alzheimer's disease (FAD) Swedish mutant (beta APPSM) form was cloned into a mammalian expression vector (PK255) containing the CMV promoter. The vector was transfected into Chinese hamster ovary cells containing human muscarinic m1 receptors (CHO-m1), and clonal cells stably(More)
The purpose of our studies was to determine the effects of muscarinic receptor agonists on conditioned avoidance responding in the rat. Rats were trained to avoid or escape an electric shock delivered to the feet in a discrete trial procedure. The muscarinic receptor agonists pilocarpine and [2-ethyl-8-methyl-2,8-diazaspiro(4. 5)decane-1,3-dione](More)
Two dimeric analogs of the muscarinic acetylcholine receptor (mAChR) agonist phenylpropargyloxy-1,2,5-thiadiazole-quinuclidine (NNC 11-1314) were synthesized and pharmacologically evaluated. In radioligand binding assays on Chinese hamster ovary (CHO) cell membranes expressing the individual human M(1) to M(5) mAChR subtypes, both dimers(More)
Using a known dual PPARalpha/gamma activator (5) as a structural template, SAR evaluations led to the identification of triple PPARalpha/gamma/delta activators (18-20) with equal potency and efficacy on all three receptors. These compounds could become useful tools for studying the combined biological effects of PPARalpha/gamma/delta activation.
