In Vitro Tests of FDM 3D-Printed Diclofenac Sodium-Containing Implants

One of the most promising emerging innovations in personalized medication is based on 3D printing technology. For use as authorized medications, 3D-printed products require different in vitro tests, including dissolution and biocompatibility investigations. Our objective was to manufacture implantable drug delivery systems using fused deposition modeling, and in vitro tests were performed for the assessment of these products. Polylactic acid, antibacterial polylactic acid, polyethylene terephthalate glycol, and poly(methyl methacrylate) filaments were selected, and samples with 16, 19, or 22 mm diameters and 0%, 5%, 10%, or 15% infill percentages were produced. The dissolution test was performed by a USP dissolution apparatus 1. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide dye (MTT)-based prolonged cytotoxicity test was performed on Caco-2 cells to certify the cytocompatibility properties. The implantable drug delivery systems were characterized by thermogravimetric and heatflow assay, contact angle measurement, scanning electron microscopy, microcomputed tomography, and Raman spectroscopy. Based on our results, it can be stated that the samples are considered nontoxic. The dissolution profiles are influenced by the material properties of the polymers, the diameter, and the infill percentage. Our results confirm the potential of fused deposition modeling (FDM) 3D printing for the manufacturing of different implantable drug delivery systems in personalized medicine and may be applied during surgical interventions.

Nickel-Catalyzed, Regio- and Enantioselective Benzylic Alkenylation of Olefins with Alkenyl Bromide

A NiH-catalyzed migratory hydroalkenylation reaction of olefins with alkenyl bromides has been developed, affording benzylic alkenylation products with high yields and excellent chemoselectivity. The mild conditions of the reaction preclude olefinic products from undergoing further isomerization or subsequent alkenylation. Catalytic enantioselective hydroalkenylation of styrenes was achieved by using a chiral bisoxazoline ligand.

A dual functional Janus membrane combining superwettability with electrostatic force for controllable anionic/cationic emulsion separation and in situ surfactant removal

In the oil/water emulsion treatment field, the separation of dispersed tiny oil droplets and the removal of surfactants are both significant in order to obtain purified water. Superwetting materials have proved to be an ideal solution for stabilized emulsion separation. However, most of the previous studies only focus on the separation of oil from water while neglecting the removal of surfactants. With the purpose of realizing in situ emulsion separation and surfactant removal, a dual functional Janus membrane is designed inspired by mussel-inspired chemistry and an EDC/NHS coupling reaction. After modification, abundant amino groups and carboxyl groups are decorated on two sides of the microfiltration membrane substrate, respectively (denoted as the -NH2 side and -COOH side). Combining special wettability with electrostatic interaction, the as-prepared membrane is able to separate stabilized oil-in-water emulsions and remove anionic/cationic surfactants simultaneously. The -NH2 side is used for the treatment of anionic emulsions with the surfactant sodium dodecyl sulfate (SDS), while the -COOH side is used for the treatment of cationic emulsions with the surfactant hexadecyl trimethyl ammonium bromide (CTAB). More importantly, the separation efficiencies are all above 99.5% and the surfactant removal efficiencies are up to 95.7%. To our knowledge, this is the first time to treat both dispersed oil droplets and surfactants using superwetting materials. The excellent recyclability and stability of the Janus material make it a potential candidate for application in the industrial field.

A combine approach of chemical synthesis, biological evaluation and structural dynamics studies revealed thiazole substituted arylamine derivatives as potent FabH enzyme inhibitors

Bacterial FabH enzyme is a broad-spectrum antimicrobial target and can be used in the design of novel antibiotics. This study reports chemical synthesis of thiazole based amine compounds as FabH inhibitors, followed by biological evaluation, and computational drug designing analysis with ultimate objective to guide further biological optimization of the identified hits. The compounds were synthesized through Pd-PEPPSI catalyzed cross coupling strategy for the Buchwald-Hartwig amination of thiazole-substituted aryl bromide. Pd-PEPPSI pre catalysts were utilized for the cross couple with the diverse range of functionalized electron-deficient and electron-rich anilines and aliphatic amines. The thiazole based heteroaryl bromide coupling was found to be challenging and only specialized Pd-PEPPSI-IPr and Pd-PEPPSI-IPent catalysts were found to be effective providing the coupling product yield in the range of 78% to 99%. Biological investigation depicted compound 3f to be effective against Bacillus subtilis, Staphylococcus aureus, Staphylococcus epidermis, and Escherichia coli with mean + standard deviation value of 9.6 +/- 0.4, 11.6 +/- 0.4, 15.6 +/- 0.4, and 11.6 +/- 0.4, respectively. This compound is also active against free radicals with EC90 value of 39.45 mu g/ml. Comparative docking predictions unravel the 3f binding mode at FabH active tunnel as such to block complete access for the natural substrate and involved balanced hydrogen and hydrophobic interactions. FabH-3f complex dynamics in solution found the docked conformation between the protein and compound of higher stability with mean carbon alpha deviation of 1.87 angstrom and mean residual deviation of 0.88 angstrom. Intermolecular interactions analysis depicted Asn274 from FabH active pocket to be significant in compound holding and strengthening of interaction as the simulation progresses. This was supported further by radial distribution function (RDF) and axial frequency distribution (AFD) that demonstrated the high distribution of compound atoms in close proximity of Asn274 residue and decrease in interaction distance. Further, the docking and simulation findings were validated through MMPB/GBSA methods that complements the compound affinity for the said target. In a nutshell, the identified hit could be subjected to structure, biological and pharmacokinetic optimization for development of effective FabH inhibitors.

Hsa-circ_0010283 Regulates Oxidized Low-Density Lipoprotein-Induced Proliferation and Migration of Vascular Smooth Muscle Cells by Targeting the miR-133a-3p/Pregnancy-Associated Plasma Protein A Axis

Background: The dysfunction of vascular smooth muscle cells (VSMCs) contributes to the development of atherosclerosis. This study aimed to investigate the role of circular RNA-0010283 (circ_0010283) in oxidized low-density lipoprotein (ox-LDL)-treated VSMCs and the associated action mechanism. Methods and Results: The expression of circ_0010283 was investigated using quantitative real-time polymerase chain reaction (qRT-PCR). Cell proliferation was monitored by using a 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. Cell apoptosis was detected by using flow cytometry assay. A transwell assay was performed to observe migration and invasion, and a scratch assay was implemented to test migration. The expression of proliferation, apoptosis and migration/invasion-related proteins was measured by using a western blot. The targeted relationship was predicted by using a bioinformatics tool (Starbase) and verified by using a dual-luciferase reporter assay, a RNA immunoprecipitation (RIP) assay and a RNA pull-down assay. circ_0010283 was highly expressed in serum samples from atherosclerosis patients and ox-LDL-treated human VSMCs (HVSMCs). circ_0010283 knockdown suppressed ox-LDL-induced proliferation, migration and invasion in HVSMCs. MicroRNA-133a-3p (miR-133a-3p) was confirmed as a target of circ_0010283, and miR-133a-3p deficiency reversed the effects of circ_0010283 knockdown. Moreover, pregnancy-associated plasma protein A (PAPPA) was targeted by miR-133a-3p, and PAPPA overexpression reversed the effects of miR-133a-3p restoration. Interestingly, circ_0010283 could regulate PAPPA expression by mediating miR-133a-3p. Conclusions: circ_0010283 participated in ox-LDL-induced dysfunctions of HVSMCs by modulating the miR-133a-3p/PAPPA pathway, suggesting that circ_0010283 might be associated with atherosclerosis pathogenesis.

Development of a Novel Quinoline Derivative as a P-Glycoprotein Inhibitor to Reverse Multidrug Resistance in Cancer Cells

Multidrug resistance (MDR) is one of conventional cancer chemotherapy’s limitations. Our group previously synthesized a series of quinoline-based compounds in an attempt to identify novel anticancer agents. With a molecular docking analysis, the novel compound 160a was predicted to target p-glycoprotein, an MDR candidate. The purpose of this study is to evaluate 160a’s MDR reversal effect and investigate the underlying mechanism at the molecular level. To investigate 160a’s inhibitory effect, we used a series of parental cancer cell lines (A549, LCC6, KYSE150, and MCF-7), the corresponding doxorubicin-resistant cell lines, an MTS cytotoxicity assay, an intracellular doxorubicin accumulation test, and multidrug resistance assays. The Compusyn program confirmed, with a combination index (CI) value greater than 1, that 160a combined with doxorubicin exerts a synergistic effect. Intracellular doxorubicin accumulation and transported calcein acetoxymethyl (AM) (a substrate for p-glycoprotein) were both increased when cancer cells with MDR were treated with compound 160a. We also showed that compound 160a’s MDR reversal effect can persist for at least 1 h. Taken together, these results suggest that the quinoline compound 160a possesses high potential to reverse MDR by inhibiting p-glycoprotein-mediated drug efflux in cancer cells with MDR.

Self-Assembled Surfactant-Templated Synthesis of Porous Hollow Silica Nanoparticles: Mechanism of Formation and Feasibility of Post-Synthesis Nanoencapsulation

SiO2 is bioinert and highly functionalizable, thus making it a very attractive material for nanotechnology applications such as drug delivery and nanoencapsulation of pesticides. Herein, we synthesized porous hollow SiO2 nanoparticles (PHSNs) by using cetyltrimethylammonium bromide (CTAB) and Pluronic P123 as the structure-directing agents. The porosity and hollowness of the SiO2 structure allow for the protective and high-density loading of molecules of interest inside the nanoshell. We demonstrate here that loading can be achieved post-synthesis through the pores of the PHSNs. The PHSNs are monodisperse with a mean diameter of 258 nm and a specific surface area of 287 m(2) g(-1). The mechanism of formation of the PHSNs was investigated using 1-D and 2-D solid-state nuclear magnetic resonance (SS-NMR) and Fourier-transform infrared spectroscopy (FTIR). The data suggest that CTAB and Pluronic P123 interact, forming a hydrophobic spherical hollow cage that serves as a template for the porous hollow structure. After synthesis, the surfactants were removed by calcination at 550 degrees C and the PHSNs were added to an Fe3+ solution followed by addition of the reductant NaBH4 to the suspension, which led to the formation of Fe(0) NPs both on the PHSNs and inside the hollow shell, as confirmed by transmission electron microscopy imaging. The imaging of the formation of Fe(0) NPs inside the hollow shell provides direct evidence of transport of solute molecules across the shell and their reactions within the PHSNs, making it a versatile nanocarrier and nanoreactor.

Liquid crystal-based sensing platform for detection of Pb2+ assisted by DNAzyme and rolling circle amplification

Lead ions (Pb2+) are one of the most widespread heavy metal contaminants that pose detrimental impact on environment and human health. We demonstrate a highly sensitive and specific liquid crystal (LC)-based sensing platform for detecting Pb2+ assisted by DNAzyme and rolling circle amplification (RCA). Magnetic beads (MBs) are functionalized with DNA duplexes of the catalytic strands (DNAzymes) and the substrate strands. In the presence of Pb2+, the substrate strands are disassembled due to activation of the DNAzyme, which allows initiation of DNA RCA on MBs. The amplified DNA strands can disrupt arrangement of octadecy trimethyl ammonium bromide monolayers (OTAB), thereby inducing planar orientation of LC molecules at the interface of aqueous and LCs. Thus, LCs exhibit bright appearance. In contrast, RCA cannot be triggered in the absence of Pb2+. Therefore, LC molecules adopt perpendicular orientation at the interface, which induces the dark morphology of LCs. The limit of detection reaches as low as 16.7 pM. It is an improvement of more than two orders of magnitude compared to that of previously reported LC-based sensing approaches. This approach also shows excellent performance in monitoring Pb2+ in tap water and lake water.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 2032-35-1. The above is the message from the blog manager. SDS of cas: 2032-35-1.
