Decreased activity of the medial prefrontal cortex (mPFC) has been considered a basis for core symptoms of schizophrenia, an illness associated with a neurodevelopmental origin. Evidence from preclin. and clin. studies indicates that serotonin (5-HT)1A receptors play a crucial role in the energy metabolism of the mPFC. This study was undertaken to determine (1) if transient blockade of N-methyl-D-aspartate receptors during the neonatal stage inhibit energy demands in response to stress, as measured by extracellular lactate concentrations, in the mPFC at the young adult stage, and (2) if tandospirone, a 5-HT1A partial agonist, reverses the effect of the neonatal insult on energy metabolism Male pups received MK-801 (0.20 mg/kg) on postnatal days (PDs) 7-10. On PD 63, footshock stress-induced lactate levels were measured using in vivo microdialysis technique. Tandospirone (0.1, 1.0, and 5.0 mg/kg) was administered once daily for 14 days before the measurement of lactate levels. Neonatal MK-801 treatment suppressed footshock stress-induced lactate production in the mPFC, but not caudate-putamen, whereas basal lactate levels were not significantly changed in either brain region. The MK-801-induced suppression of footshock stress-induced lactate production in the mPFC was attenuated by tandospirone at 1.0mg/kg/day, but not 0.1 or 5.0 mg/kg/day, which is an effect antagonized by coadministration of WAY-100635, a selective 5-HT1A antagonist. These results suggest a role for impaired lactate metabolism in some of the core symptoms of schizophrenia, for example, neg. symptoms and cognitive deficits. The implications for the ability of 5-HT1A agonism to ameliorate impaired lactate production in the mPFC of this animal model are discussed. Synapse, 2012. 漏 2011 Wiley Periodicals, Inc.

And the article was included in Indian Journal of Microbiology in 2022.Application of 62893-19-0 This article mentions the following:

This study aims to determine the antimicrobial resistance (AMR) pattern in freshwater ornamental cyprinids, such as Goldfish and Tiger barb. Mol. characterization of bacterial isolates confirmed the presence of 7 bacterial isolates in Goldfish and 6 in Tiger barb. Antimicrobial susceptibility test using 36 antibiotics revealed a higher resistance pattern for bacitracin, rifampicin, trimethoprim, cefalexin, ampicillin, amoxicillin, nalidixic acid and nitrofurantoin. Sulphafurazole, norfloxacin and ciprofloxacin were effective against all the bacterial isolates derived from Goldfish and Tiger barb. Most bacterial isolates exhibited > 0.2 multi-drug resistance index (MDR), indicating the severity of antibiotic use in the culture system. The finding of the present study suggests that ornamental fish may act as the reservoir of MDR bacteria and dissemination of resistance genes to clin. and human commensal bacteria through horizontal gene transfer.

Fibroblast growth factor receptor 1 (FGFR1) a tyrosine kinase receptor, plays important roles in angiogenesis, embryonic development, cell proliferation, cell differentiation, and wound healing. The FGFR isoforms and their receptors (FGFRs) considered as a potential targets and under intense research to design potential anticancer agents. Fibroblast growth factors (FGF’s) and its growth factor receptors (FGFR) plays vital role in one of the critical pathway in monitoring angiogenesis. In the current study, quant. pharmacophore models were generated and validated using known FGFR1 inhibitors. The pharmacophore models were generated using a set of 28 compounds (training). The top pharmacophore model was selected and validated using a set of 126 compounds (test set) and also using external validation. The validated pharmacophore was considered as a virtual screening query to screen a database of 400,000 virtual mols. and pharmacophore model retrieved 2800 hits. The retrieved hits were subsequently filtered based on the fit value. The selected hits were subjected for docking studies to observe the binding modes of the retrieved hits and also to reduce the false positives. One of the potential hits (thiazole-2-amine derivative) was selected based the pharmacophore fit value, dock score, and synthetic feasibility. A few analogs of the thiazole-2-amine derivative were synthesized. These compounds were screened for FGFR1 activity and anti-proliferative studies. The top active compound showed 56.87% inhibition of FGFR1 activity at 50 渭M and also showed good cellular activity. Further optimization of thiazole-2-amine derivatives is in progress.

To determine the maximum tolerated dose (MTD) dose-limiting toxicity, and pharmacokinetic and pharmacodynamic profile of TKI258 (formerly CHIR-258). A phase I dose escalating trial in patients with advanced solid tumors was performed. Treatment was initially as single daily doses on an intermittent 7-day on/7-day off schedule. Following a protocol amendment, a second schedule comprised, during cycle 1, 7-day on/7-day off treatment followed by 14 days of continuous daily dosing; subsequent cycles comprised 28 days of daily dosing. Pharmacokinetics and evaluation of phosphorylated extracellular signal-regulated kinase (ERK) in peripheral blood mononuclear cells were done during the first 28 days of each schedule. Thirty-five patients were treated in four intermittent (25-100 mg/d) and three continuous (100-175 mg/d) dosing cohorts. Observed drug-related toxicities were nausea and vomiting, fatigue, headache, anorexia, and diarrhea. Dose-limiting toxicities were grade 3 hypertension in one patient at 100 mg continuous dosing, grade 3 anorexia in a second patient at 175 mg, and grade 3 alk. phosphatase elevation in a third patient at 175 mg. One patient had a partial response (melanoma) and two patients had stable disease >6 mo. TKI258 pharmacokinetics were linear over the dose range of 25 to 175 mg. Five of 14 evaluable patients had modulation of phosphorylated ERK levels. The MTD was defined as 125 mg/d. Evidence of antitumor activity in melanoma and gastrointestinal stromal tumors warrants further investigation, and other phase I studies are ongoing. Further pharmacodynamic evaluation is required in these studies to evaluate the biol. effects of TKI258. In the experiment, the researchers used many compounds, for example, 4-Amino-5-fluoro-3-(6-(4-methylpiperazin-1-yl)-1H-benzo[d]imidazol-2-yl)quinolin-2(1H)-one 2-hydroxypropanoate (cas: 692737-80-7Formula: C24H27FN6O4).

Preclinical pharmacological profiles and clinical efficacy of the novel antipsychotic drug brexpiprazole (REXULTI Tablets 1 mg, 2 mg) was written by Suzuki, Mikio;Niidome, Kazunari;Maeda, Kenji;Kikuchi, Tetsuro;Usami, Tomohiro;Futamura, Takashi. And the article was included in Nippon Yakurigaku Zasshi in 2019.Recommanded Product: 7-(4-(4-(Benzo[b]thiophen-4-yl)piperazin-1-yl)butoxy)quinolin-2(1H)-one This article mentions the following:

Brexpiprazole (Rexulti) is the second antipsychotic agent in the world with dopamine D2 receptor partial agonist which was developed by Otsuka Pharmaceutical Co. Ltd. It is categorized as “Serotonin- dopamine Activity Modulator (SDAM)” that regulates both serotoninergic and dopaminergic systems by acting as a partial agonist for serotonin 5-HT1A receptors and D2 receptors and as an antagonist for 5-HT2A receptors. In preclin. pharmacol. studies, brexpiprazole showed the equivalent antipsychotic-like effects to those of other atypical antipsychotics. And it was suggested that brexpiprazole has the low potentials to induce extrapyramidal symptoms, hyperprolactinemia and tardive dyskinesia, with improvement effects on cognitive dysfunction. Furthermore, brexpiprazole has the weak effects on histamine H1 receptors which are associated with sedation and weight gain in clin. In the clin. trials in patients with schizophrenia in both acute and maintenance phase, brexpiprazole showed improvement of antipsychotic effects against placebo, and low incidence of adverse events, e.g., extrapyramidal symptoms, hyperprolactinemia, and weight gain, as suggested in preclin. studies. Furthermore, brexpiprazole showed low incidence of metabolic abnormalities. In particular, brexpiprazole showed relatively low incidences of akathisia, insomnia and agitation which has been commonly reported with aripiprazole. This would be based on the pharmacol. features of brexpiprazole that is more potent antagonism at 5-HT2A receptors and D2 receptors partial agonism with lower intrinsic activity compared to those of aripiprazole. In conclusion, brexpiprazole could be one of the antipsychotics with the most rational mechanism of action, and the better efficacy and safety/tolerability profiles would contribute to the treatment of patients with schizophrenia. In the experiment, the researchers used many compounds, for example, 7-(4-(4-(Benzo[b]thiophen-4-yl)piperazin-1-yl)butoxy)quinolin-2(1H)-one (cas: 913611-97-9Recommanded Product: 7-(4-(4-(Benzo[b]thiophen-4-yl)piperazin-1-yl)butoxy)quinolin-2(1H)-one).

The endocannabinoid system impacts seizures in a mouse model of Dravet syndrome was written by Anderson, Lyndsey L.;Doohan, Peter T.;Hawkins, Nicole A.;Bahceci, Dilara;Garai, Sumanta;Thakur, Ganesh A.;Kearney, Jennifer A.;Arnold, Jonathon C.. And the article was included in Neuropharmacology in 2022.Computed Properties of C20H22F9N3O2 This article mentions the following:

Dravet syndrome is a catastrophic childhood epilepsy with multiple seizure types that are refractory to treatment. The endocannabinoid system regulates neuronal excitability so a deficit in endocannabinoid signaling could lead to hyperexcitability and seizures. Thus, we sought to determine whether a deficiency in the endocannabinoid system might contribute to seizure phenotypes in a mouse model of Dravet syndrome and whether enhancing endocannabinoid tone is anticonvulsant. Scn1a+/- mice model the clin. features of Dravet syndrome: hyperthermia-induced seizures, spontaneous seizures and reduced survival. We examined whether Scn1a+/- mice exhibit deficits in the endocannabinoid system by measuring brain cannabinoid receptor expression and endocannabinoid concentrations Next, we determined whether pharmacol. enhanced endocannabinoid tone was anticonvulsant in Scn1a+/- mice. We used GAT229, a pos. allosteric modulator of the cannabinoid (CB1) receptor, and ABX-1431, a compound that inhibits the degradation of the endocannabinoid 2-arachidonoylglycerol (2-AG). The Scn1a+/- phenotype is strain-dependent with mice on a 129S6/SvEvTac (129) genetic background having no overt phenotype and those on an F1 (129S6/SvEvTac x C57BL/6J) background exhibiting a severe epilepsy phenotype. We observed lower brain cannabinoid CB1 receptor expression in the seizure-susceptible F1 compared to seizure-resistant 129 strain, suggesting an endocannabinoid deficiency might contribute to seizure susceptibility. GAT229 and ABX-1431 were anticonvulsant against hyperthermia-induced seizures. However, subchronic ABX1431 treatment increased spontaneous seizure frequency despite reducing seizure severity. Cnr1 is a putative genetic modifier of epilepsy in the Scn1a+/- mouse model of Dravet syndrome. Compounds that increase endocannabinoid tone could be developed as novel treatments for Dravet syndrome. In the experiment, the researchers used many compounds, for example, 1,1,1,3,3,3-Hexafluoropropan-2-yl 4-(2-(pyrrolidin-1-yl)-4-(trifluoromethyl)benzyl)piperazine-1-carboxylate (cas: 1446817-84-0Computed Properties of C20H22F9N3O2).

Mastitis is a widespread disease in dairy cattle occurring throughout the world. The increased use of antibiotics brings about the development of antibiotic-resistant microbes. The application of antibiotics in dairy farming led to increased antibiotic resistance and represents a major obstacle for the treatment of mastitis. Recent advancements in nanotechnol. led to the development of nanocolloids to overcome disadvantages posed by conventional antimicrobial agents. Hence, a novel, environmentally friendly, cost-effective, biocompatible, and long-term antibacterial represents a promising solution for medicine and farming. Hence, polyherbal nanocolloids (PHNc) was formulated by using the extracts of Syzygium aromaticum, Cinnamomum verum, Emblica officinalis, Terminalia belerica, Terminalia chebula, and Cymbopogon citratus and physicochem. characterized. From mastitis milk samples, microorganisms were isolated including Acinetobacter junii, Klebsiella pneumoniae, Pseudomonas stutzeri, and Acinetobacter baumannii and screened for antibiotic susceptibility. All the isolated strains were tested with PHNc and compared with antibiotics. Min. inhibitory concentration (MIC), min. bactericidal concentration (MBC), and biofilm assays were performed at different concentrations, and antibacterial effects were quantified. In our results, PHNc showed potent bacteriostatic, bactericidal, and antibiofilm activity against all the strains. Our results indicated that PHNc can reduce the virulence factors responsible for infection by different bacterial strains. This study confirmed that PHNc had the potential to inhibit the growth of pathogenic Gram-neg. and Gram-pos. strains and could be utilized as an alternative to antibiotics to inhibit multidrug-resistant microbial pathogens in cattle.

Hydrophobic constants and quantitative structure activity relationships (QSAR) in sets of phenothiazine drugs was written by Barbato, Francesco;Recanatini, Maurizio;Silippo, Carlo;Vittoria, Antonio. And the article was included in European Journal of Medicinal Chemistry in 1982.Category: piperazines This article mentions the following:

Octanol/water partition coefficients of a large set of phenothiazine drugs I [R = Me₂N(CH₂)₃, CH₂CHMeNMe₂, CH₂CHMeCH₂NMe₂, etc.; R¹ = H, Cl, CN, Me, CF₃, etc.] were determined and related to the corresponding high-performance liquid chromatog. capacity factors. The bovine serum albumin binding affinity and antihemolytic activity of sets of congeners are discussed from the quant. structure-activity point of view. Results show that both activities are largely affected by the degree of hydrophobicity of the mols. as measured by the log P apparent values, while other factors play only a minor role. Moreover, in vivo data are considered to uncover quant. correlations between structural features and neuroleptic biol. activities. Correlation equations show that the major factor influencing the considered activities is a particular electronic demand of the phenothiazine side chain, while 2-R¹-substituents may enhance the activity either affecting the side chain conformation or directly interacting at receptor site. In the experiment, the researchers used many compounds, for example, N,N-Dimethyl-10-(3-(4-methylpiperazin-1-yl)propyl)-10H-phenothiazine-2-sulfonamide (cas: 316-81-4Category: piperazines).
