Effect of Spiritual Care Based on the Sound Heart Model on Spiritual Experiences of Hemodialysis Patients.

Hemodialysis patients require spiritual care due to their spiritual distress. This study aimed to investigate the effect of spiritual care on spiritual experiences of hemodialysis patients. This randomized controlled trial was conducted in 2017 at hemodialysis departments of Baqiyatallah and Cham ran hospitals in Tehran.

Characterization of vabicaserin (SCA-136), a selective 5-hydroxytryptamine 2C receptor agonist.

The 5-hydroxytryptamine 2C (5-HT(2C)) receptor subtype has received considerable attention as a target for drug discovery, having been implicated in a wide variety of disorders. Here, we describe the in vitro pharmacological profile of the novel 5-HT(2C) receptor-selective agonist vabicaserin [(-)-4,5,6,7,9,9a,10,11,12,12a-decahydrocyclopenta[c] [1,4]diazepino[6,7,1-ij]quinoline hydrochloride] (SCA-136), including a comprehensive strategy to assess 5-HT(2B) receptor selectivity using diverse preparations and assays of receptor activation. Vabicaserin displaced (125)I-(2,5-dimethoxy)phenylisopropylamine binding from human 5-HT(2C) receptor sites in Chinese hamster ovary cell membranes with a K(i) value of 3 nM and was >50-fold selective over a number of serotonergic, noradrenergic, and dopaminergic receptors.

Antiobesity-like effects of the 5-HT2C receptor agonist WAY-161503.

WAY-161503 ((4aR)-8,9-dichloro-2,3,4,4a-tetrahydro-1H-pyrazino[1,2-a]quinoxalin-5(6H)-one), a 5-HT(2B/C) receptor agonist, was characterized in vitro using stable Chinese hamster ovary cell lines expressing each of the human 5-HT2 receptors and in vivo in animal models of obesity. WAY-161503 displaced both agonist ([125I]2,5-dimethoxy-4-iodoamphetamine (DOI)) and antagonist ([3H]mesulergine) radioligand binding to the human 5-HT2C receptor with derived Ki values of 3.3 +/- 0.

(4-Substituted-phenyl)-(5H-10,11-dihydro-pyrrolo [2,1-c][1,4] benzodiazepin-10-yl)-methanone derivatives as vasopressin receptor modulators.

Synthesis and structure-activity relationships (SAR) of arginine vasopressin (AVP) receptor modulators are described. Potent and selective compounds are prepared when the amide linkage connecting rings A and B of VPA-985 is replaced with a bond, CO, -O-, -S-, or -SO2- bond.

Conformationally constrained N1-arylsulfonyltryptamine derivatives as 5-HT6 receptor antagonists.

Several series of conformationally constrained N1-arylsulfonyltryptamine derivatives were prepared and tested for 5-HT6 receptor binding affinity and ability to modulate cAMP production in a cyclase assay. The 3-piperidin-3-yl-, 3-(1-methylpyrrolidin-2-ylmethyl)-, and 3-pyrrolidin-3-yl-1H-indole arrays (8-13) appear to be able to adopt a conformation that allows high affinity 5-HT6 receptor binding, while the beta-carboline array 14 binds with a significantly weaker (10- to 100-fold) affinity. N1-Benzenesulfonyl-3-piperidin-3-yl-1H-indole 9a is a high affinity full agonist with EC50 = 24 nM.
