Background: The mixed lineage kinase type 3 inhibitor URMC-099 facilitates amyloid-beta (Aβ) clearance and degradation in cultured murine microglia. One putative mechanism is an effect of URMC-099 on Aβ uptake and degradation As URMC-099 promotes endolysosomal protein trafficking and reduces Aβ microglial pro-inflammatory activities, we assessed whether these responses affect Aβ pathobiogenesis. To this end, URMC-099’s therapeutic potential, in Aβ precursor protein/presenilin-1 (APP/PS1) double-transgenic mice, was investigated in this model of Alzheimer’s disease (AD). Methods: Four-month-old APP/PS1 mice were administered i.p. URMC-099 injections at 10 mg/kg daily for 3 wk. Brain tissues were examined by biochem., mol. and immunohistochem. tests. Results: URMC-099 inhibited mitogen-activated protein kinase 3/4-mediated activation and attenuated β- amyloidosis. Microglial nitric oxide synthase-2 and arginase-1 were co-localized with lysosomal-associated membrane protein 1 (Lamp1) and Aβ. Importatly, URMC-099 restored synaptic integrity and hippocampal neurogenesis in APP/PS1 mice. Conclusions: URMC-099 facilitates Aβ clearance in the brain of APP/PS1 mice. The multifaceted immune modulatory and neuroprotective roles of URMC-099 make it an attractive candidate for ameliorating the course of AD. This is buttressed by removal of pathol. Aβ species and restoration of the brain’s microenvironment during disease.

Objective : Although selective serotonin reuptake inhibitors are now established as first-line pharmacotherapy for social anxiety disorder (SAD), other agents with different mechanisms have shown promise in treating SAD. The aim of this study was to examine the efficacy and safety of tandospirone in treating adolescents with SAD. Methods : Adolescent patients meeting the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for SAD were randomly assigned (1:1) to open-label treatment with either tandospirone or sertraline for 8 wk. The primary outcome measures were changes from baseline in the Hamilton Anxiety (HAM-A) scale and response using the Clin. Global Impression of Improvement (CGI-I) scale. Results : The adjusted mean change in HAM-A scores from baseline was indicating a significant improvement over baseline in both treatment arms (p < 0.0001). The mean CGI-I scale score at week was with no significant difference between the two arms (p = 0.42). Rates of response were 48.6% for tandospirone and 55.6% for sertraline using the CGI-I. Response rates were 37.1% for tandospirone and 41.7% for sertraline using a HAM-A response criterion (≥50% reduction). The adjusted mean change in Social Phobia Inventory scores from baseline was indicating a significant improvement over baseline in both treatment arms (p < 0.0001). Conclusions : Tandospirone is safe and effective and appears non-inferior to sertraline for SAD in youths. Copyright © 2013 John Wiley & Sons, Ltd.

Human induced pluripotent stem cell-derived sensory neurons for fate commitment of bone marrow stromal cell-derived schwann cells was written by Cai, Sa;Shum, Daisy K. Y.;Chan, Ying-Shing. And the article was included in Methods in Molecular Biology (New York, NY, United States) in 2018.SDS of cas: 1062368-24-4 This article mentions the following:

Here we describe the in vitro derivation of sensory neurons for use in effecting fate commitment of Schwann cell-like cells derived from human bone marrow stromal cells (hBMSCs). We adopt a novel combination of small mols. in an 8-day program that induces the differentiation of human induced pluripotent stem cells into sensory neurons. In co-cultures, the derived sensory neurons present contact-dependent cues to direct hBMSC-derived Schwann cell-like cells toward the Schwann cell fate. These derived human Schwann cells survive passaging and cryopreservation, retain marker expression despite withdrawal of glia-inducing medium and neuronal cues, demonstrate capacity for myelination, and therefore promise application in autologous transplantation and re-myelination therapy.

Experimental studies on pharmacological protection of the brain against focal ischemia. 2. Effects of KB-2796 and nicardipine on focal brain ischemia in rats was written by Shiino, Akihiko. And the article was included in Archiv fuer Japanische Chirurgie in 1989.SDS of cas: 101477-54-7 This article mentions the following:

It has been proposed that calcium overload triggers neuronal cell damage in the acute stage of cerebral ischemia. In this study, the effects of calcium antagonists, KB-2796 and nicardipine, on neurol. deficits and size of the infarction were studied in the rat middle cerebral artery (MCA) occlusion model. Neurol. deficits were evaluated from 1 to 24 h after occlusion of the MCA, using the grading system of Bederson et al., 1986. At 24 h post-occlusion, the brain was removed, sliced coronally, and stained with triphenyltetrazolium chloride. Size of the infarction was measured by computerized image anal. system. KB-2796 (10 mg/kg) or nicardipine (1 mg/kg) was i.p. administered immediately after occlusion of the MCA. In the KB-2796-treated group, the neurol. deficits were much improved and the size of infarction was significantly smaller, but in the nicardipine-treated group improvement was modest and did not reach the level of statistical significance. The neurol. improvement was observed in the group where KB-2796 was given at 3 h postocclusion but the size of infarction was unchanged. The results indicate that the calcium antagonists could improve focal cerebral ischemia when administered in early stage of ischemia, and that such effect is more significant with KB-2796 probably because of its higher selectivity to the cerebral vessels.

To evaluate the efficacy of continuous wound infiltration with ropivacaine to reduce acute postoperative pain in patients undergoing mastectomy for carcinoma of the breast.A randomized, double-blind, placebo-controlled trial was conducted. One hundred fifty patients were randomly assigned to receive continuous ropivacaine (0.2%) (group A, n = 74) or saline solution (0.9%) (group B, n = 76) at 10 mL/h for 48 h through a multilumen catheter placed during the surgical procedure. Postoperative morphine consumption and visual analog scale (VAS) pain scores were recorded. A quality of life score (Quality of life questionnaire Core 30) and a VAS score were obtained at 1, 3, and 6 mo after surgery.The difference in mean morphine consumption between the two groups was close to significance during the first 48 h postsurgery (P = 0.056; 10.8 ± 16.5 vs. 4.8 ± 10.4 mg). At day 1, patients in the ropivacaine-infusion group had lower morphine consumption than the control group (P = 0.0026). The link between local ropivacaine infiltration and a decrease in mean postoperative VAS scores reached significance for the first 24 h postsurgery (P = 0.039). No significant difference was found between the two arms for VAS pain scores (P = 0.36) or for quality of life (overall QLQ-C30 score, P = 0.09) at 1, 3, or 6 mo.Continuous wound infiltration with ropivacaine is efficacious in reducing postoperative pain.

Structural binding site comparisons reveal Crizotinib as a novel LRRK2 inhibitor was written by Bolz, Sarah Naomi;Salentin, Sebastian;Jennings, Gary;Haupt, V. Joachim;Sterneckert, Jared;Schroeder, Michael. And the article was included in Computational and Structural Biotechnology Journal in 2021.Formula: C23H32N6O4S This article mentions the following:

Mutations in leucine-rich repeat kinase 2 (LRRK2) are a frequent cause of autosomal dominant Parkinsons disease (PD) and have been associated with familial and sporadic PD. Reducing the kinase activity of LRRK2 is a promising therapeutic strategy since pathogenic mutations increase the kinase activity. Several small-mol. LRRK2 inhibitors are currently under investigation for the treatment of PD. However, drug discovery and development are always accompanied by high costs and a risk of late failure. The use of already approved drugs for a new indication, which is known as drug repositioning, can reduce the cost and risk. In this study, we applied a structure-based drug repositioning approach to identify new LRRK2 inhibitors that are already approved for a different indication. In a large-scale structure-based screening, we compared the protein-ligand interaction patterns of known LRRK2 inhibitors with protein-ligand complexes in the PDB. The screening yielded 6 drug repositioning candidates. Two of these candidates, Sunitinib and Crizotinib, demonstrated an inhibition potency (IC50) and binding affinity (Kd) in the nanomolar to micromolar range. While Sunitinib has already been known to inhibit LRRK2, Crizotinib is a novel LRRK2 binder. Our results underscore the potential of structure-based methods for drug discovery and development. In light of the recent breakthroughs in cryo-electron microscopy and structure prediction, we believe that structure-based approaches like ours will grow in importance.

And the article was included in Separations in 2021.Name: 6-Fluoro-1-(4-fluorophenyl)-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid This article mentions the following:

NanoMIPs that are prepared by solid phase synthesis have proven to be very versatile, but to date only limited attention has been paid to their use in solid phase extraction Thus, since nanoMIPs show close similarities, in terms of binding behavior, to antibodies, it seems relevant to verify if it is possible to use them as mimics of the natural antibodies that are used in immunoextn. methods. As a proof-of-concept, we considered prepared nanoMIPs against fluoroquinolone ciprofloxacin. Several nanoMIPs were prepared in water with polymerization mixtures of different compositions The polymer with the highest affinity towards ciprofloxacin was then grafted onto a solid support and used to set up a solid phase extraction-HPLC method with fluorescence detection, for the determination of fluoroquinolones in human urine. The method resulted in successful selection for the fluoroquinolone antibiotics, such that the nanoMIPs were suitable for direct extraction of the antibiotics from the urine samples at the μg mL-1 level. They required no preliminary treatment, except for a 1 + 9 (volume/volume) dilution with a buffer of pH 4.5 and they had good analyte recovery rates; up to 85% with precision in the range of 3 to 4.5%, without interference from the matrix.

4-(cis-4,5-Bis(4-chlorophenyl)-2-(2-isopropoxy-4-methoxyphenyl)-4,5-dihydro-1H-imidazole-1-carbonyl)piperazin-2-one (cas: 548472-68-0) belongs to piperazine derivatives. A form in which piperazine is commonly available industrially is as the hexahydrate, C4H10N2. 6H2O, which melts at 44 °C and boils at 125–130 °C. Two common salts in the form of which piperazine is usually prepared for pharmaceutical or veterinary purposes are the citrate, 3C4H10N2.2C6H8O7 (i.e. containing 3 molecules of piperazine to 2 molecules of citric acid), and the adipate, C4H10N2.C6H10O4 (containing 1 molecule each of piperazine and adipic acid).Formula: C30H30Cl2N4O4

Analysis of Protein-Protein Interaction in a Single Live Cell by Using a FRET System Based on Genetic Code Expansion Technology was written by Park, Seong-Hyun;Ko, Wooseok;Lee, Hyun Soo;Shin, Injae. And the article was included in Journal of the American Chemical Society in 2019.Formula: C30H30Cl2N4O4 This article mentions the following:

Hsp70 is known to directly bind to Bax for suppression of apoptosis. However, mechanisms on how Bax is dissociated from its complex with Hsp70 during apoptosis remain largely unknown. In the current study, the authors developed the efficient fluorescence resonance energy transfer (FRET) system which consisted of Hsp70-YFP and fluorescent amino acid (ANAP)-incorporated Bax, which was generated by using genetic code expansion technol., and applied the FRET system to elucidate mechanisms on how apoptosis-inducing substances dissociate Bax from Hsp70. Time-dependent anal. of single live cell images showed that Bax activators binding to Bax trigger sites inhibited the Bax-Hsp70 interaction but a Bax activator, which blocks phosphorylation of S184 via binding to the C-terminal S184 site, did not affect this interaction. Addnl., an inhibitor for Hsp70-Hsp40 interaction blocked the Bax-Hsp70 interaction. Furthermore, p53 activators promoted the dissociation of Bax from Hsp70 by reactivating p53 which disrupted the Bax-Hsp70 interaction. The authors also found that death ligands and a Bcl-2 inhibitor enhanced the dissociation of Bax from Hsp70 by activating activator BH3-only proteins. Results from this effort suggest that FRET systems consisting of the ANAP-incorporated protein and the YFP fusion protein will be valuable tools to gain an understanding of other types of protein-protein interactions. In the experiment, the researchers used many compounds, for example, 4-(cis-4,5-Bis(4-chlorophenyl)-2-(2-isopropoxy-4-methoxyphenyl)-4,5-dihydro-1H-imidazole-1-carbonyl)piperazin-2-one (cas: 548472-68-0Formula: C30H30Cl2N4O4).
