Valproic acid (VPA) is an anticonvulsant drug that also used to treat migraines and bipolar disorder. Its proposed biological targets include human voltage-gated sodium channels, among other membrane proteins. We the prokaryotic NavMs channel, which has been shown be a good exemplar for binding examine structural functional interactions of VPA. Thermal melt synchrotron radiation circular dichroism spectroscopic studies full-length channel (which includes both pore voltage sensor domains),...
Proteins are dynamic macromolecules that perform vital functions in cells. A protein structure determines its function, but this is not static, as proteins change their conformation to achieve various functions. Understanding the conformational landscapes of essential understand mechanism action. Sets carefully chosen conformations can summarize such complex and provide better insights into function than single conformations. We refer these sets representative ensembles. Recent advances...
Histamine and its receptors were first described as part of immune gastrointestinal systems, but their presence in the central nervous system importance behavior are gaining more attention. The histaminergic modulates different processes including wakefulness, feeding, learning memory consolidation. (H1R, H2R, H3R, H4R) belong to rhodopsin-like family G protein-coupled receptors, present constitutive activity, subjected inverse agonist action. involvement brain disorders, such Alzheimer's...
Mitochondrial trifunctional protein (TFP) deficiency is an inherited metabolic disorder leading to a block in long-chain fatty acid β-oxidation. Mutations either HADHA and HADHB, which encode the TFPα β subunits, respectively, usually result combined TFP deficiency. A single common mutation, c.1528G>C (p.E510Q), leads isolated 3-hydroxyacyl-CoA dehydrogenase (LCHAD) also catalyzes step remodeling of cardiolipin (CL), phospholipid critical mitochondrial membrane stability function. We...
Engineered proteins capable of binding and transporting nucleic acids hold significant potential for advancing disease control in both the medical agricultural fields. However, identifying small acid-binding domains remains challenging, as existing predictors primarily classify entire binders or nonbinders rather than targeting specific regions. Here, we introduce NABhClassifier, a highly efficient precise web server designed to detect helical sequences with potential. Featuring an intuitive...
As the dopamine D3R receptor is a promising target for schizophrenia treatment, an improved understanding of binding existing antipsychotics to this crucial development new potent and more selective therapeutic agents. In work, we have used X-ray cocrystallization data antagonist eticlopride bound as template predict, through docking essays, placement typical antipsychotic drug haloperidol at site. Afterward, classical quantum mechanics/molecular mechanics (QM/MM) computations were employed...
Tissue engineering is a potential approach to regenerate damaged tissue by the combination and synergism among scaffolding material, cell source signaling factors. In present study, mesenchymal stem cells (MSCs) were isolated from C57BL/6 mice, cultured on poly(D, L-lactide-co-glycolide) (PLGA) scaffold produced electrospinning technique differentiated into chondrogenic lineage. After seeding, MSCs responsive became flattened with fibroblast-like morphology demonstrated presence of actin...
Cell transplantation is a promising experimental treatment for spinal cord injury. The aim of the present study was to evaluate efficacy mononuclear cells from human umbilical blood in promoting functional recovery when transplanted after contusion Female Wistar rats (12 weeks old) were submitted injury with MASCIS impactor and divided into 4 groups: control, surgical injury, one cell-treated lesion group. Mononuclear male neonates two experiments: a) 1 h surgery, site at concentration 5 x...
Tissue engineering is a technique by which live tissue can be re-constructed and one of its main goals to associate cells with biomaterials. Electrospinning that facilitates the production nanofibers commonly used develop fibrous scaffolds in engineering. In present study, different approach for cell incorporation into was tested. Mesenchymal stem were extracted from wall umbilical cord mononuclear blood. Cells re-suspended 10% polyvinyl alcohol solution subjected electrospinning 30 min...
Results of optical absorption measurements are presented together with calculated structural, electronic, and properties for the anhydrous monoclinic L-asparagine crystal. Density functional theory (DFT) within generalized gradient approximation (GGA) including dispersion effects (TS, Grimme) was employed to perform calculations. The revealed that crystal is a wide band gap material 4.95 eV main energy. DFT-GGA+TS simulations, on other hand, produced structural parameters in very good...
In the quest to improve treatment of Parkinson´s disease and Schizophrenia, one proposed strategies has been development subtype selective ligands targeting D2 D3 dopamine receptors. An essential advance for this type strategy was recent crystallographic elucidation human receptor structure in complex with antagonist eticlopride, revealing important features ligand-binding pocket. Taking data into account, we have performed a quantum biochemistry investigation eticlopride binding order...
Risperidone is an atypical antipsychotic used in the treatment of schizophrenia and symptoms irritability associated with autism spectrum disorder (ASD). Its main action mechanism blockade D2-like receptors acting over positive negative small risk extrapyramidal (EPS) at doses corresponding to low/moderate D2 occupancy. Such a decrease side effect incidence can be its fast unbinding from nigrostriatal region allowing recovery dopamine signaling pathways. We performed docking essays using...
An unprecedented research effort has been undertaken in response to the ongoing COVID-19 pandemic. This included determination of hundreds crystallographic structures SARS-CoV-2 proteins, and numerous virtual screening projects searching large compound libraries for potential drug inhibitors. Unfortunately, these initiatives have had very limited success producing effective inhibitors against proteins. A reason might be an often overlooked factor computational efforts: receptor flexibility....
The lipase kinetic resolution (KR) of aryloxy-propan-2-yl acetates, via hydrolysis, produced enantiomerically pure/enantioenriched mexiletine intermediates and analogs. Racemic acetates rac-1-(2,6-dimethylphenoxy)propan-2-yl acetate (rac-5a), rac-1-(2,4-dimethylphenoxy)propan-2-yl (rac-5b), rac-1-(o-tolyloxy)propan-2-yl (rac-5c) rac-1-(naphthalen-1-yloxy)propan-2-yl (rac-5d) were used as substrates. A preliminary screening (24 h, phosphate buffer pH 7.0 with 20% acetonitrile co-solvent, 30...
Chronic myeloid leukemia (CML) is caused by constitutively active fusion protein BCR-ABL1, and targeting ABL1 a promising therapy option. Imatinib, dasatinib, nilotinib have all been shown to work effectively in clinical trials. mutations, particularly the T315I gate-keeper mutation, cause resistance patients. As result, broad-spectrum medicines are desperately needed. In order screen potential drugs CML, mebendazole (MBZ) was subjected vitro test against CML cell lines (K562 FEPS)...
