A Synbiotic Mixture Augmented the Efficacy of Doxepin, Venlafaxine
A synbiotic mixture augmented the efficacy of doxepin, venlafaxine, and fluvoxamine in mice model of depression Azadeh Mesripour1, Andiya Meshkati1, Valiolah Hajhashemi2 1Department of Pharmacology and Toxicology, School of Pharmacy and Pharmaceutical Sciences, Isfahan University of Medical Sciences, Isfahan, IRAN. 2‐ Isfahan Pharmaceutical Sciences Research Center, School of Pharmacy and Pharmaceutical Sciences, Isfahan University of Medical Sciences, Isfahan, IRAN. ABSTRACT Objective: Currently available antidepressant drugs have notable downsides; in addition to their side effects and slow onset of action their moderate efficacy in some individuals, may influence compliance. Previous literature has shown that probiotics may have antidepressant effects. Introducing complementary medicineproof in order to augment the efficacy of therapeutic doses of antidepressant drugs seems to be very important. Therefore the effect of adding a synbiotic cocktail in drinking water was assessed in mice model of despair following administrating three antidepressant drugs belonging to different classes. Methods: The marble burring test (MBT), and forced swimming test (FST) were used as animal model of obsessive behavior and despair. The synbiotic cocktail was administered in mice drinking water (6.25×106 CFU) for 14 days and the tests were performed on the days 7 and 14 thirty minutes after injecting the lowest dose of doxepin (1 mg/kg), venlafaxine (15 mg/kg), and fluvoxamine (15 mg/kg). Results: After 7 days of the synbiotic ingestion immobility time decreased in FST for doxepin (92 sec ± 5.5) and venlafaxine (17.3 sec ± 2.5) compared to their control group (drinking water) but fluvoxamine could decrease immobility time after 14 days of ingesting the synbiotic (70 sec ± 7.5). -

GPCR/G Protein
Inhibitors, Agonists, Screening Libraries www.MedChemExpress.com GPCR/G Protein G Protein Coupled Receptors (GPCRs) perceive many extracellular signals and transduce them to heterotrimeric G proteins, which further transduce these signals intracellular to appropriate downstream effectors and thereby play an important role in various signaling pathways. G proteins are specialized proteins with the ability to bind the nucleotides guanosine triphosphate (GTP) and guanosine diphosphate (GDP). In unstimulated cells, the state of G alpha is defined by its interaction with GDP, G beta-gamma, and a GPCR. Upon receptor stimulation by a ligand, G alpha dissociates from the receptor and G beta-gamma, and GTP is exchanged for the bound GDP, which leads to G alpha activation. G alpha then goes on to activate other molecules in the cell. These effects include activating the MAPK and PI3K pathways, as well as inhibition of the Na+/H+ exchanger in the plasma membrane, and the lowering of intracellular Ca2+ levels. Most human GPCRs can be grouped into five main families named; Glutamate, Rhodopsin, Adhesion, Frizzled/Taste2, and Secretin, forming the GRAFS classification system. A series of studies showed that aberrant GPCR Signaling including those for GPCR-PCa, PSGR2, CaSR, GPR30, and GPR39 are associated with tumorigenesis or metastasis, thus interfering with these receptors and their downstream targets might provide an opportunity for the development of new strategies for cancer diagnosis, prevention and treatment. At present, modulators of GPCRs form a key area for the pharmaceutical industry, representing approximately 27% of all FDA-approved drugs. References: [1] Moreira IS.

Roluperidone (MIN-101)
Cognitive Vitality Reports® are reports written by neuroscientists at the Alzheimer’s Drug Discovery Foundation (ADDF). These scientific reports include analysis of drugs, drugs-in- development, drug targets, supplements, nutraceuticals, food/drink, non-pharmacologic interventions, and risk factors. Neuroscientists evaluate the potential benefit (or harm) for brain health, as well as for age-related health concerns that can affect brain health (e.g., cardiovascular diseases, cancers, diabetes/metabolic syndrome). In addition, these reports include evaluation of safety data, from clinical trials if available, and from preclinical models. Roluperidone (MIN-101) Evidence Summary The evidence for roluperidone is limited to a single randomized controlled trial in schizophrenia patients. Roluperidone may interact with medications that inhibit CYP2D6. Neuroprotective Benefit: Roluperidone improved several cognitive scores in schizophrenia patients, but it is not known whether it would benefit age-related cognitive decline or dementia. Aging and related health concerns: No studies have tested roluperidone for age-related conditions. Safety: Common adverse events with roluperidone included headache and anxiety based on a study in schizophrenia patients, though a few serious adverse events were also observed (vomiting, syncope, bradycardia). May interact with CYP2D6 inhibitors. 1 Availability: Not available; in Dose: The clinical trial in Chemical formula: C22H23FN2O2 clinical trials schizophrenia patients tested two MW: 366.4 oral doses: 32 mg/day -

Differential Modulation of the Central and Peripheral Monoaminergic Neurochemicals by Deprenyl in Zebrafish Larvae
toxics Article Differential Modulation of the Central and Peripheral Monoaminergic Neurochemicals by Deprenyl in Zebrafish Larvae Marina Bellot 1, Helena Bartolomé 1, Melissa Faria 2, Cristian Gómez-Canela 1,* and Demetrio Raldúa 2,* 1 Department of Analytical Chemistry and Applied (Chromatography Section), School of Engineering, Institut Químic de Sarrià-Universitat Ramon Llull, Via Augusta 390, 08017 Barcelona, Spain; [email protected] (M.B.); [email protected] (H.B.) 2 Institute for Environmental Assessment and Water Research (IDAEA-CSIC), Jordi Girona, 18, 08034 Barcelona, Spain; [email protected] * Correspondence: [email protected] (C.G.-C.); [email protected] (D.R.); Tel.: +34-93-2672343 (C.G.-C.); +34-93-4006138 (D.R.) Abstract: Zebrafish embryos and larvae are vertebrate models increasingly used in translational neuroscience research. Behavioral impairment induced by the exposure to neuroactive or neurotoxic compounds is commonly linked to changes in modulatory neurotransmitters in the brain. Although different analytical methods for determining monoaminergic neurochemicals in zebrafish larvae have been developed, these methods have been used only on whole larvae, as the dissection of the brain of hundreds of larvae is not feasible. This raises a key question: Are the changes in the monoaminergic profile of the whole larvae predictive of the changes in the brain? In this study, the levels of ten monoaminergic neurotransmitters were determined in the head, trunk, and the whole body of zebrafish larvae in a control group and in those treated for 24 h with 5 M deprenyl, Citation: Bellot, M.; Bartolomé, H.; a prototypic monoamine-oxidase B inhibitor, eight days post-fertilization.
