Abstract:
Discover new antifungal drugs by evaluating the efficacy of heterocyclic compounds. Investigate the potential of yeast Sec14p protein as a target for antifungal drugs. Compare the effectiveness of Auto Dock and PyRX software for docking simulations of heterocyclic compounds against Sec14p. Docking simulations were performed using Auto Dock and PyRX software to assess the binding affinity of five specific heterocyclic compounds to the yeast Sec14p protein. The reference compound for comparison was a known antifungal agent with a Picolamide scaffold (PDB ID: 6FOE). Atovaquone exhibited the strongest binding affinity (-9.4 kcal/mol) using PyRX. A known antifungal agent showed a significant discrepancy in binding energy between Auto Dock (-6.2 kcal/mol) and PyRX (-3.64 kcal/mol). This study explores a novel class of compounds (Quinones) for antifungal drug discovery. It highlights the potential of yeast Sec14p protein as a target for antifungal drugs. The findings suggest that PyRX might be more suitable for docking simulations of certain compound classes than Auto Dock. This emphasizes the importance of software selection based on the specific molecules under investigation. Keywords: Molecular docking, Quinones, Antifungal, PyRX, Auto dock

Abstract:
Background: Tenofovir disoproxil fumarate (TDF) is a first-line nucleotide analog (NA) drug for hepatitis B therapy. Long-term NA therapy increases peripheral T cell levels to enhance antiviral response, while CTLA-4 inhibits the activation. Objective: This study analyzed the interaction between TDF and CTLA-4 through molecular docking. Methods: Target protein and ligand data mining were performed, and proteins were prepared by removing water molecules in the Discovery Studio 2019 software. The energy minimization was performed on ligands using Pyrx v.0.9.8 software. Protein-ligand docking was performed using Autodock Vina integrated with Pyrx v.09.8. Meanwhile, the docking of proteins was accomplished using the Haddock server. The BioVia Discovery Studio 2019 software visualized the interaction between the compound and the docked protein. Molecular dynamics simulations were carried out using the YASARA Dynamic program developed by Biosciences GmbH. Results: TDF ligand has good and stable inhibitory activity against the CTLA-4/B7-1 and CTLA4/B7-2 complexes. TDF docking has been shown to initiate conformational changes, indicating the ligand’s inhibitory activity. The significant conformational changes based on superimposition results were shown by the CTLA-4/TDF/B7-2 and CTLA-4/B7-1/TDF complexes. TDF in all ligands undergoes bonding and displacement of binding sites. Conclusion: Treatment with TDF was predicted to have inhibitory activity against CTLA-4, especially in its complex form with B7-1 and B7-2.

Abstract:
Cachexia is a serious but under recognised consequence of many chronic diseases. The positive role of Ashwagandha in debility has been evaluated in several studies. But the underlying molecular mechanism is unclear. In the present study, network pharmacology is used to understand the molecular basis of its action. Methods: The phytoconstituents of Ashwagandha were screened from IMPPAT database and literature. The effective compounds were screened by drug likeness score and pharmacokinetic characteristics (ADMET). The target genes of effective compounds were predicted from BindingDB. The cachexia genes were found in gene-cards database, and cachexia related target genes were screened by comparison. Then the related pathways and correlation analysis were explored by the Genomes (KEGG) database. Finally, the networks of compound-target, target-pathway, and pathway-disease of Ashwagandha were constructed by Cytoscape software v3.7.2. Docking studies were carried out with PyRx software and analyzed in Biovia discovery studio visualizer. Results: The effective ingredients of Ashwagandha in cachexia were Withanolide S, Withanolide E, Withanolide D, Withasomniferol A and Beta sitosterol. The network analysis showed the highly modulating proteins were PTGS2, AR, PRKCB, JUN, TERT, NFE2L2, MDM2 and TNF which are related to cachexia and act on the pathways like MAPK signalling, MicroRNAs in cancer, cAMP signalling etc. The ligands and targets were retrieved from the PubChem, Protein Data Bank and docked using PyRx software. Conclusion: The present study is enabling to understand scientific evidence at the molecular level of balya action which has been proved clinically earlier.

Abstract:
Alzheimer’s disease (AD) dementia is a type of neurodegenerative disease, refers to a distinct arrival and certainly functional and mental decline which is linked with age which eventually leads to death. This current study was to demonstrate the role of pulegone against Glypican-1 for the treatment of Alzheimer’s disease through an in-silico approach. Methods: All the information and studies were gleaned from molecular docking. With the use of docking software, Docking was implemented between the target protein GPC1 (PDB ID: 4YWT) and the entire ligands. We preferred GPC1 (PDB ID: 4YWT) as a target protein and several natural compounds such as Rosmarinic acid, Allo ocimene, and Pulegone as ligands. When the preparation of protein is done, in PyRx software we introduced the entire ligand for the process of virtual screening. As reported by the result of PyRx and Lipinski’s Rule of Five, the finest compound against GPC1 with its smallest amount of binding energy was Pulegone. Results: For the procedure of molecular docking between the receptor protein GPC1 (PDB ID: 4YWT) and Pulegone a software called AutoDock Vina was used. The outcome showed 9 poses with distinct binding energy, RMSD LB (Root means square deviation Lower Bound), RMSD UB (Root mean square deviation Upper Bound). Through PyMol (an open-access tool for the visualization of the molecule), the interaction amidst Pulegone and GPC1 can be visualized. Conclusion: The merely compound which can restrain the activity of GPC1 (PDB ID: 4YWT) was Pulegone, based on the in-silico approach. Therefore in the advanced studies, Pulegone can be a capable medicine acquired from natural sources for dealing with Alzheimer’s disease.

Full text
Abstract:
Conventional screening of potential drug candidates through wet lab affinity experiments using libraries of thousands of modified molecules is time and resource consuming, along with the fact that it contributes to the widening time gap between the discovery of disease-causing mutations and the implementation of resulting novel treatments. It is necessary to explore whether the preliminary use of high-throughput virtual screening (HTVS) software such as PyRx will curb both the time and money spent in discovering novel treatments for diseases such as congenital heart defects (CHDs). For example, AXIN2, a protein involved in a negative feedback loop inhibiting the Wnt/β-catenin signaling pathway important for cardiogenesis, has recently been associated with CHD. The loss-of-function mutation L10F on the tankyrase-binding domain of AXIN2 has been shown to upregulate the pathway by loss of inhibition ability, leading to the accumulation of intracellular β-catenin. In a different paper, however, AXIN2 has been shown to be stabilized using XAV-939, a small-molecule drug which targets tankyrase. PyRx and VMD will be used to modify the drug in order to increase its binding affinity to AXIN2, stabilizing the protein and reinstating its inhibitory property to treat CHDs. When used in adjunction to wet lab experiments, HTVS software may decrease costs and the time required to bring a potentially life-saving treatment into use.

Abstract:
Uterine leiomyosarcoma (ULMS) is an uncommon gynecological cancer, and treatments such as surgical debulking, chemotherapy, and radiotherapy have had limited results. This investigation study is about a scenario of a 53- year-old woman, whereby conventional protocol through combining doxetatacel, gemcitabine, pazopanib, pemetrexed, and doxorubicin with surgery and radiation did not avoid metastasis, resulting in the death of the patient. A strategy of personalized tumor therapy was used. Through the recommendation of a ctdna (circulating tumor DNA) next-generation sequencing (NGS) using blood sample, the mutated tp53 c338y was identified. A built homology of the mutated TP 53 proteins with a drug library of 1133 FDA approved drugs can be used in repurposing as part of the therapy regimen. Virtual drug screening using molecular docking was performed with PyRx 0.8 and dockey software. The top 10 drugs were found to bind to the target genes. Three from the top 10 were further refined with AutoDock 4.2.6. The identification of small molecules could essentially be utilized for personalized leiomyosarcoma, specially with patients carrying the tp53 mutations. This concept of personalized tumor therapy could be effective not only for uterine leiomyosarcoma but for other tumors as well.

Abstract:
Pancreatic ductal adenocarcinoma (PDAC) represents one of the most aggressive cancers, with a 5-year survival rate of only 8%. The progression of the disease is significantly influenced by the tumor microenvironment, especially by cell-extracellular matrix (ECM) interactions. The aim of this study is to repurpose small molecules as inhibitor candidates to jointly target key receptors for the ECM attachment, specifically discoidin domain receptors (DDR1 and DDR2), which are implicated in promoting tumor growth through cell-collagen interactions.Using a computational drug repurposing framework, we accomplished ligand docking and virtual screening to identify potential inhibitory agents targeting DDR1 and DDR2. Ligand libraries including 8540 small chemical molecules (neutral charge, molecular weight of 450-500 Da and logP of 2-3 were chosen) were assembled from the Zinc15 database, and 3D structure files of DDR1 (PDB ID: 6BSD) and DDR2 (PDB ID: 2WUH) were processed (removal of water and heteroatoms, polar hydrogen addition, missing atom repair, etc.) using Discovery Studio Software. Following virtual screening by PyRx software, the top 20 ligands were validated by in silico molecular docking using AutoDock4 and PyMOL via parameters such as inhibition constants and affinity scores compared to the known anticancer drugs of Dasatinib, Imatinib, Nilotinip, Ponatinib.Herein, our study has come out with promising candidates, particularly compounds ZINC0000958672 and ZINC000013960048, that can commonly be used for both DDR1 and DDR2 inhibition, with higher efficacy observed for DDR1. These findings suggest that highlighted molecules may be potent to manage PDAC aggressiveness and offer new avenues for therapeutic interventions by targeting ECM receptors and related critical signaling pathways. Consequently, this research bridges the gap between computational drug discovery and clinical applications, aiming to improve treatment outcomes for PDAC patients.

Abstract:
Results are presented experimentally measuring the localized temperature profile due to microscale boiling of a silicon-Pyrex bonded wafer with a 100 μm deep, 500 μm wide and six mm long microchannel. Experiments were performed using an infrared camera equipped with a magnifying lens. By using a camera, the dynamic temperature profile is shown from the inside channel all the way out to where the temperature of the wafer reaches the bulk temperature of the heating source. Temperature profiles are shown for both water and methanol as the working fluid applying between five and twenty degrees Celsius of superheat to the bulk wafer. Using these results, a discussion of the relevant heat transfer modes and nondimensional numbers is given to gain insight into the range of influence that phase change in a microchannel has on the temperature of the wafer. Additionally, discussion is given about modeling of microscale phase change using a commercial fluid dynamics software package. The importance of these results with respect to implementation into the fuel intake manifold for a micro engine based portable power system is also discussed.

Abstract:
The micro-inductor is a key component in wireless power transmission micro modules. In this paper, an optimum design for the micro-inductor was studied and related MEMS fabrication techniques were also developed. Commercial electromagnetic property analysis software, ANSOFT, was used to screen the main design factors of the micro-inductor. It was found that the high inductance and high quality factors of the micro-inductor implied high power transmission efficiency for the micro-module’s wireless power transmission. The electrical performance of the micro-inductor was affected by the thermal stress and thermal strain induced in the operational environment of the wireless power transmission micro-module. In order to investigate the reliability of the micro-inductor, commercial stress analysis software, ANSYS, was used to calculate thermal stress and thermal strain. The deformed model of the micro-inductor was then imported into ANSOFT in order to calculate its electrical properties. Glass substrate Pyrex 7740 was used to reduce the substrate loss of the magnetic flux of the micro-inductor. The surface micromachining technique, a kind of MEMS processing, was chosen to fabricate the micro-inductor; the coil of the micro-inductor was electroplated with copper to reduce the series resistance. The minimum line width and line space of the coil were 20 μm and 20 μm respectively. Polyimide (PI) was used for supporting the structure of micro-inductors. The maximum shear stress was 74.09MPa and the maximum warpage was 2.197 μm at a thermal loading of 125°C. For the simulated data, the most suitable areas for 31-turn and 48-turn coils were at an area ratio of 1.27 and 2, respectively. The electrical properties of the inductors changed slightly under thermal loading.

Abstract:
Abstract A gas or vapor compressor is one of the key components of many engineering systems, such as certain designs of vapor compression refrigeration systems, cryo-coolers, air handlers. For meso-scale systems with linear dimensions of a few centimeters, conventional designs do not work efficiently because of rather large relative tolerances, and hence these meso-scale systems require micro-fabricated components for efficient operation. This paper presents a meso-scale centrifugal compressor fabricated by photo-lithographic techniques. A preliminary design based on 1-D flow analysis using air as the working fluid shows that a 50 mm diameter centrifugal compressor with a blade height of 200 μm gives a static pressure ratio of 1.12. In this design, the impeller has 10 full blades and 10 splitter blades. Each blade has the NACA profile 9510 with the maximum camber at 50% of the chord. These impeller blades have exit angles 35° with exit flow angles of 60°. A vaned diffuser having 20 equally spaced vanes with the same NACA profile is used to improve compressor efficiency. A 3-D compressible, viscous flow analysis has been done using a commercial finite volume software. The results of this analysis allowed the verification of the flow characteristics inside the meso-scale centrifugal compressor. The compressor has been fabricated using micro-fabrication techniques. The rotor and the stator are made by etching a silicon wafer by using DRIE (Deep Reactive Ion Etching) technique. A Pyrex wafer is then bonded to the stator for visual access inside the compressor.
