On November 20, 2019, Daneshyar, Anahita; Nematollahi, Davood; Varmaghani, Fahimeh; Goljani, Hamed; Alizadeh, Hojjat published an article.Reference of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone The title of the article was Electrochemical synthesis of a new phosphonium betaine. Kinetic evaluation and antibacterial susceptibility. And the article contained the following:

Cyclic voltammetry, controlled-potential coulometry, chronoamperometry, chronocoulometry and chronopotentiometry methods were used for the electrochem. study of 1-acetyl-4-(4-hydroxyphenyl)piperazine (APIP) in the presence of PPh3 (TPP) as a nucleophile. Electrochem. generated APIPox can serve as a Michael acceptor for nucleophilic attack by TPP to yield a new phosphonium betaine (APTP). The authors prepared a new product in good yield and purity by reaction of TPP with APIPox in an undivided cell equipped with C anode. Based on an EC mechanism, the observed homogeneous rate constant (kobs) of the Michael addition reaction of APIPox with TPP were estimated by comparing the exptl. cyclic voltammograms with the digital simulated results. Also, electrochem. oxidation of APIP was studied both exptl. and theor. to provide insight into the influence of natural charge and thermodn. stability parameters on the type of chem. reaction which follows APIPox. The synthesized compound was evaluated for in vitro antibacterial. The experimental process involved the reaction of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone(cas: 67914-60-7).Reference of 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone

On November 20, 2021, Garrosa-Jimenez, Javier; Sanchez Carro, Yolanda; Ovejero-Benito, Maria C.; del Sastre, Eric; Garcia, Antonio G.; Lopez, Manuela G.; Lopez-Garcia, Pilar; Cano-Abad, Maria F. published an article.Recommanded Product: N-((4-(4-Phenylpiperazin-1-yl)tetrahydro-2H-pyran-4-yl)methyl)-2-(phenylthio)nicotinamide The title of the article was Intracellular calcium and inflammatory markers, mediated by purinergic stimulation, are differentially regulated in monocytes of patients with major depressive disorder. And the article contained the following:

The P2X7 receptor (P2X7R) is a ligand-gated ion channel that is being recognized as a major player in neuropsychiatric disorders such as Major Depressive Disorder (MDD). P2X7R activation is triggered by high extracellular ATP concentrations, leading to channel opening and inducing an increase in cytosolic calcium concentration ([Ca2+]c), that activates the inflammatory pathway. Those receptors are expressed not only in CNS cells but also in peripheral blood cells, where they are activated in response to inflammatory mols. such as bacterial lipopolysaccharide (LPS). LPS induced-tissue damage promotes an elevation of extracellular ATP, triggering the NRLP3-inflammasome assembly and activation that, sequentially, induces caspase-1 cleavage and IL-1β processing and secretion. In this context, we attempt to understand the role of P2X7R in [Ca2+]c homeostasis regulation, inflammasome expression and its pharmacol. modulation in MDD. For this purpose, monocytes were isolated from peripheral blood of MDD patients and [Ca2+]c was monitored with the intracellular probe Fura-2. Our results point out to P2X7R as the responsible of the Ca2+ imbalance, as well as TNF-α-dependent activation of caspase-1 in MDD patients. In addition, P2X7R blockade with its specific antagonist, JNJ-47965567, reduces the Ca2+ entry upon Bz-ATP exposure. Altogether, our results point that MDD patients have both, Ca2+ homeostasis alteration and an inflammatory status, which promote an independent-inflammasome activation of caspase-1. Therefore, we propose the pharmacol. modulation of P2X7R as a therapeutic approach against MDD symptoms.

Extracellular ATP (ATP) in the brain is suggested to be an etiol. factor of major depressive disorder (MDD). It has been assumed that stress-released ATP stimulates P2X7 receptors (Rs) at the microglia, thereby causing neuroinflammation; however, other central nervous system (CNS) cell types such as astrocytes also possess P2X7Rs. In order to elucidate the possible involvement of the MDD-relevant hippocampal astrocytes in the development of a depressive-like state, we used various behavioral tests (tail suspension test [TST], forced swim test [FST], restraint stress, inescapable foot shock, unpredictable chronic mild stress [UCMS]), as well as fluorescence immunohistochem., and patch-clamp electrophysiol. in wild-type (WT) and genetically manipulated rodents. The TST and FST resulted in learned helplessness manifested as a prolongation of the immobility time, while inescapable foot shock caused lower sucrose consumption as a sign of anhedonia. We confirmed the participation of P2X7Rs in the development of the depressive-like behaviors in all forms of acute (TST, FST, foot shock) and chronic stress (UCMS) in the rodent models used. Further, pharmacol. agonists and antagonists acted in a different manner in rats and mice due to their diverse potencies at the resp. receptor orthologs. In hippocampal slices of mice and rats, only foot shock increased the current responses to locally applied dibenzoyl-ATP (Bz-ATP) in CA1 astrocytes; in contrast, TST and restraint depressed these responses. Following stressful stimuli, immunohistochem. demonstrated an increased co-localization of P2X7Rs with a microglial marker, but no change in co-localization with an astroglial marker. Pharmacol. damage to the microglia and astroglia has proven the significance of the microglia for mediating all types of depression-like behavioral reactions, while the astroglia participated only in reactions induced by strong stressors, such as foot shock. Because, in addition to acute stressors, their chronic counterparts induce a depressive-like state in rodents via P2X7R activation, we suggest that our data may have relevance for the etiol. of MDD in humans.

On August 15, 2017, Platania, Chiara Bianca Maria; Giurdanella, Giovanni; Di Paola, Luisa; Leggio, Gian Marco; Drago, Filippo; Salomone, Salvatore; Bucolo, Claudio published an article.COA of Formula: C28H32N4O2S The title of the article was P2X7 receptor antagonism: Implications in diabetic retinopathy. And the article contained the following:

Diabetic retinopathy (DR) is the most frequent complication of diabetes and one of leading causes of blindness worldwide. Early phases of DR are characterized by retinal pericyte loss mainly related to concurrent inflammatory process. Recently, an important link between P2X7 receptor (P2X7R) and inflammation has been demonstrated indicating this receptor as potential pharmacol. target in DR. Here the authors first carried out an in silico mol. modeling study in order to characterize the allosteric pocket in P2X7R, and identify a suitable P2X7R antagonist through mol. docking. JNJ47965567 was identified as the hit compound in docking calculations, as well as for its absorption, distribution, metabolism and excretion (ADME) profile. As an in vitro model of early diabetic retinopathy, human retinal pericytes were exposed to high glucose (25 mM, 48 h) that caused a significant (p < 0.05) release of IL-1β and LDH. The block of P2X7R by JNJ47965567 significantly (p < 0.05) reverted the damage elicited by high glucose, detected as IL-1β and LDH release. Overall, the findings suggest that the P2X7R represents an attractive pharmacol. target to manage the early phase of diabetic retinopathy, and the compound JNJ47965567 is a good template to discover other P2X7R selective antagonists. The experimental process involved the reaction of N-((4-(4-Phenylpiperazin-1-yl)tetrahydro-2H-pyran-4-yl)methyl)-2-(phenylthio)nicotinamide(cas: 1428327-31-4).COA of Formula: C28H32N4O2S
