A surfactant-free approach: Novel one-step ultrasonic nebulizer spray method to generate amphiphilic Janus particles was written by Daradmare, Sneha;Lee, Hag Sung;Seo, Tae Seok;Park, Bum Jun. And the article was included in Journal of Colloid and Interface Science in 2022.Application of 38215-36-0 The following contents are mentioned in the article:

A solvent evaporation-induced phase separation method, which is based on the preferential partitioning of two or more immiscible materials after solvent evaporation on providing heat, has been one of the main strategies for synthesis of Janus particles (JPs). Considering this approach, it should be possible to synthesize surfactant free-JPs in continuous flow by the ultrasonic nebulizer spray method. Two polymers, polystyrene and polymethylmethacrylate, were dissolved in dichloromethane, and droplets of a precursor solution generated by an ultrasonic nebulizer were then conveyed through a borosilicate glass cylinder with two heating zones. The solvent evaporation-induced phase separation occurred in a single flow process, which resulted in the preferential partitioning of two incompatible polymers in the droplets, leading to the formation of the spherical bicompartmental JPs. The successful fabrication of spherical JPs was observed at high polymer concentrations (1.5 and 2.0 wt%), and at elevated temperature (40-75°C). The fluorescent compartmentalization of JPs was confirmed. Furthermore, the interfacial arrangement of JPs at oil-water interface was studied. A detailed explanation of theor. prediction of interfacial configurations of JPs was provided. Lastly, the generated JPs were proved as Pickering stabilizers at the oil-water interface. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Application of 38215-36-0).

Nux vomica has been used in China as a traditional medicine for treatment of liver cancer, but its clin. use is limited by serious side-effects. Studies have shown that brucine and strychnine are the main active components of nux vomica. The objective of this research was to develop a transdermal brucine-strychnine transethosome (BS-TE) formulation that could be taken up by hepatoma cells in vitro and inhibit their proliferation. The BS-TE formulation was optimized by central composite design-response surface methodol. (CCD-RSM). The average total entrapment efficiency of BS-TE was 92.50% ± 0.0489% and the average total drug loading was 8.63% ± 0.0289%. In vitro release and percutaneous permeation of BS-TE were investigated by dynamic dialysis and Franz diffusion cell methods. Fluorescence microscopy combined with flow cytometry anal. was used to study the in vitro cellular uptake of transethosomes. In addition, MTT assay was used to evaluate in vitro cytotoxicity. The results showed that compared with free brucine and strychnine, BS-TE exhibited better transdermal permeation. The BS-TE formulation was taken up by hepatoma cells in vitro and slowly released the active components to give long-term, potent inhibition of proliferation. This research provides a new approach for the development and clin. application of brucine and strychnine.

Pharmacoengineered Lipid Core-Shell Nanoarchitectonics to Influence Human Alveolar Macrophages Uptake for Drug Targeting Against Tuberculosis was written by Thalla, Maharshi;Vijayakumar, Gangipangi;Selvaraju, Sudhagar;Banerjee, Subham. And the article was included in Journal of Inorganic and Organometallic Polymers and Materials in 2022.Electric Literature of C20H18N2O2S The following contents are mentioned in the article:

Macrophage uptake and modulation based on nanoparticle characteristics are key areas for improving the internalisation process and successfully delivering the drug to intracellular organelles where Mycobacterium tuberculosis resides and persists. The two methods for designing nanoarchitectonics are active and passive targeting. Owing to the limitations of therapeutic approaches, we aimed to build nanoarchitectonics with both passive and active targeting properties. Lipid core-shell nanoarchitectonics were prepared using the double emulsification method, and their size, zeta potential, surface morphol., thermal and crystalline behavior, and pyrazinamide (PZA) payload and release were determined In human alveolar macrophages, comparative uptake, intracellular and compartmental colocalisation, and effectiveness against Mycobacterium smegmatis-infected macrophages were examined Nanoarchitectures obtained with smooth and hydrophobic surfaces were monodisperse, had a neg. zeta potential, and were irregular in shape. Furthermore, macrophage uptake and intracellular and compartmental colocalisation were more evident in macrophage cell lines, and increased efficacy was observed in the bacterium-infected cell lines. These findings show that ligand-tethered and PZA-loaded nanoarchitectonics are promising strategies for tuberculosis (TB) treatment. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Electric Literature of C20H18N2O2S).

Oral administration is the best way for the most patients due to the good compliance, and intestinal epithelium is the main barrier of oral drug absorption. In order to overcome the small intestine epithelial barrier to orally deliver water-insoluble drugs, deoxycholic acid (DA), a substrate of the intestinal bile acid transporters, conjugated poly (2-ethyl-2-oxazoline)-poly (D, L-lactide) (DA-PEOz-PLA) was designed and synthesized, and deoxycholic acid-modified polymeric micelles composed of DA-PEOz-PLA and mPEG-PLA were fabricated to encapsulate model drug coumarin 6 (C6) based on intestinal bile acid pathway. The structure of DA-PEOz-PLA was confirmed using ¹H NMR and TLC, and the mol. weight measured by GPC was 10034 g/mol with a PDI of 1.51. The C6-loaded polymeric micelles with drug loading content of 0.085% were characterized to have 40.11 nm in diameter and uniform spherical morphol. observed by TEM. Furthermore, the deoxycholic acid-modified polymeric micelles were demonstrated to further enhance the transmembrane transport efficiency. The mechanic study evidenced that anchorage of deoxycholic acid onto the micelles surface enriched their transcellular transport pathway. Therefore, the designed deoxycholic acid-modified polymeric micelles might have a promising potential for oral delivery of water-insoluble drugs.

3D Laser Displays Based on Circularly Polarized Lasing from Cholesteric Liquid Crystal Arrays was written by Zhan, Xiuqin;Xu, Fa-Feng;Zhou, Zhonghao;Yan, Yongli;Yao, Jiannian;Zhao, Yong Sheng. And the article was included in Advanced Materials (Weinheim, Germany) in 2021.Electric Literature of C20H18N2O2S The following contents are mentioned in the article:

Three-dimensional (3D) laser displays play an important role in next-generation display technols. owing to the ultimate visual experience they provide. Circularly polarized (CP) laser emissions, featuring optical rotatory power and invariability under rotations, are attractive for 3D displays due to potential in enhancing contrast ratio and comfortability. The lack of pixelated self-emissive CP microlaser arrays as display panels hinders the implementation of 3D laser displays. Full-color 3D laser displays are demonstrated based on CP lasing with inkjet-printed cholesteric liquid crystal (CLC) arrays as display panels. Individual CP lasers are realized by embedding fluorescent dyes into CLCs with their left-/right-handed helical superstructures serving as distributed feedback microcavities, bringing in ultrahigh circular polarization degree values (g_em = 1.6). These CP microlaser pixels exhibit excellent far-field color-rendering features and a relatively large color gamut for high-fidelity displays. With these printed CLC red-green-blue (RGB) microlaser arrays serving as display panels, proof-of-concept full-color 3D laser displays are demonstrated via delivering images with orthogonal CP laser emissions into one’s left and right eyes. These results provide valuable enlightenment for the development of 3D laser displays.

Poly-(lactic-co-glycolic) acid (PLGA) is a biodegradable, biosafe, and biocompatible copolymer. The Aspergillus section Nigri causes otomycosis localized in the external auditory canal. In this research, Aspergillus brasiliensis, a species belonging to the Nigri section, was tested. Coumarin 6 and pterostilbene loaded in poly-(lactic-co-glycolic) acid nanoparticles (PLGA-coumarin6-NPs and PLGA-PTB-NPs) were tested for fungal cell uptake and antifungal ability against A. brasiliensis biofilm, resp. Moreover, the activity of PLGA-PTB-NPs in inhibiting the A. brasiliensis infection was tested using Galleria mellonella larvae. The results showed a fluorescence signal, after 50 nm PLGA-coumarin6-NPs treatment, inside A. brasiliensis hyphae and along the entire thickness of the biofilm matrix, which was indicative of an efficient NP uptake. Regarding antifungal activity, a reduction in A. brasiliensis biofilm formation and mature biofilm with PLGA-PTB-NPs has been demonstrated. Moreover, in vivo experiments showed a significant reduction in mortality of infected larvae after injection of PLGA-PTB-NPs compared to free PTB at the same concentration In conclusion, the PLGA-NPs system can increase the bioavailability of PTB in Aspergillus section Nigri biofilm by overcoming the biofilm matrix barrier and delivering PTB to fungal cells.

A Tumor-Penetrating Nanomedicine Improves the Chemoimmunotherapy of Pancreatic Cancer was written by Tong, Qi-Song;Miao, Wei-Min;Huang, Hua;Luo, Jia-Qi;Liu, Rong;Huang, Yong-Cong;Zhao, Dong-Kun;Shen, Song;Du, Jin-Zhi;Wang, Jun.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most malignant tumors with a low survival rate. The therapeutic effect of chemotherapy and immunotherapy for PDAC is disappointing due to the presence of dense tumor stroma and immunosuppressive cells in the tumor microenvironment (TME). Herein, a tumor-penetrating nanoparticle is reported to modulate the deep microenvironment of PDAC for improved chemoimmunotherapy. The tumor pH-sensitive polymer is synthesized by conjugating N,N-dipentylethyl moieties and monomethoxylpoly(ethylene glycol) onto PAMAM dendrimer, into whose cavity a hydrophobic gemcitabine (Gem) prodrug is accommodated. They self-assemble into nanoparticles (denoted as SPN@Pro-Gem) with the size around 120 nm at neutral pH, but switch into small particles (≈8 nm) at tumor site to facilitate deep delivery of Gem into the tumor parenchyma. In addition to killing cancer cells that resided deeply in the tumor tissue, SPN@Pro-Gem could modulate the TME by reducing the abundance of tumor-associated macrophages and myeloid-derived suppressor cells as well as upregulating the expression level of PD-L1 of tumor cells. This collectively facilitates the infiltration of cytotoxic T cells into the tumors and renders checkpoint inhibitors more effective in previously unresponsive PDAC models. This study reveals a promising strategy for improving the chemoimmunotherapy of pancreatic cancer.

Targeted delivery of chemotherapeutic agents is considered a prominent strategy for the treatment of cancer due to its site-specific delivery, augmented penetration, bioavailability, and improved therapeutic efficiency. In the present study, we employed UniPR126 as a carrier in a mixed nanomicellar delivery system to target and deliver anticancer drug NIC specifically to cancer cells via EphA2 receptors as these receptors are overexpressed in cancer cells but not in normal cells. The specificity of the carrier was confirmed from the significant enhancement in the uptake of coumarin-6 loaded mixed nanomicelle by EphA2 highly expressed PC-3 cells compared to EphA2 low expressed H4 cells. Further, niclosamide-loaded lithocholic acid tryptophan conjugate-based mixed nanomicelle has shown significant synergistic cytotoxicity in PC-3 but not in H4 cells. In vivo anticancer efficacy data in PC-3 xenograft revealed a significant reduction in the tumor volume (66.87%) with niclosamide-loaded lithocholic acid tryptophan conjugate nanomicelle, where pure niclosamide showed just half of the activity. Mol. signaling data by western blotting also indicated that niclosamide-loaded lithocholic acid tryptophan conjugate nanomicelle interfered with the EphA2 receptor signaling and inhibition of the Wnt/beta-catenin pathway and resulted in the synergistic anticancer activity compared to niclosamide pure drug.

The main aim of the present investigation highlights the development of mannose appended rifampicin containing solid lipid nanoparticles (Mn-RIF-SLNs) for the management of pulmonary TB. The developed Mn-RIF-SLNs showed particle size of Mn-RIF-SLNs (479 ± 13 nm) which was found to be greater than that of unconjugated SLNs (456 ± 11 nm), with marginal reduction in percentage entrapment efficiency (79.41 ± 2.42%). The in vitro dissolution studies depicted an initial burst release followed by sustained release profile indicating biphasic release pattern, close-fitting Weibull model having least F-value. The cytotoxicity studies using J774A.1 cell line represented that the developed SLNs were non-toxic and safe as compared to free drug. Fluorescence imaging and flow cytometric (FACS) anal. depicted significant (1.79-folds) intracellular uptake of coumarin-6 (fluorescent marker) loaded Mn-C6-SLNs. The in vivo pharmacokinetic studies in sprague-dawley rats were performed and Mn-RIF-SLNs showed remarkable enhancement in terms of relative bioavailability (∼17-folds) as compared to its drug solution via oral administration. The biodistribution studies revealed higher lung accumulation (1.8-folds) of Mn-RIF-SLNs as compared to the Un-RIF-SLNs. In conclusion, the developed Mn-RIF-SLNs could serve as a promising tool for delivering the drug cargo to the site of infection (lungs) in the treatment of TB.

Construction of IL-13 Receptor alpha2-Targeting Resveratrol Nanoparticles against Glioblastoma Cells: Therapeutic Efficacy and Molecular Effects was written by Lin, Xiao-Min;Shi, Xiao-Xiao;Xiong, Le;Nie, Jun-Hua;Ye, Hai-Shan;Du, Jin-Zi;Liu, Jia. And the article was included in International Journal of Molecular Sciences in 2021.Computed Properties of C20H18N2O2S The following contents are mentioned in the article:

Glioblastoma multiforme (GBM) is the most common lethal primary brain malignancy without reliable therapeutic drugs. IL-13Rα2 is frequently expressed in GBMs as a mol. marker. Resveratrol (Res) effectively inhibits GBM cell growth but has not been applied in vivo because of its low brain bioavailability when administered systemically. A sustained-release and GBM-targeting resveratrol form may overcome this therapeutic dilemma. To achieve this goal, encapsulated Res 30 ± 4.8 nm IL-13Rα2-targeting nanoparticles (Pep-PP@Res) were constructed. UV spectrophotometry revealed prolonged Res release (about 25%) from Pep-PP@Res in 48 h and fluorescent confocal microscopy showed the prolonged intracellular Res retention time of Pep-PP@Res (>24 h) in comparison with that of free Res (<4 h) and PP@Res (<4 h). MTT and EdU cell proliferation assays showed stronger suppressive effects of Pep-PP@Res on rat C6 GBM cells than that of PP@Res (p = 0.024) and Res (p = 0.009) when used twice for 4 h/day. Pep-PP@Res had little toxic effect on normal rat brain cells. The in vivo anti-glioblastoma effects of Res can be distinctly improved in the form of Pep-PP@Res nanoparticles via activating JNK signaling, upregulating proapoptosis gene expression and, finally, resulting in extensive apoptosis. Pep-PP@Res with sustained release and GBM-targeting properties would be suitable for in vivo management of GBMs. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Computed Properties of C20H18N2O2S).

3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. The higher aromaticity of thiazole is due to delocalization of a lone pair of sulfur electrons across the ring, which is evidenced by chemical shifts of ring hydrogen at δ 7.27 and 8.77 ppm (C2 and C4), indicating diamagnetic ring current. The pyridine-type nitrogen in the thiazole ring deactivates the ring for electrophilic substitution reactions, which is further reduced in acid due to protonation of the thiazole ring.Computed Properties of C20H18N2O2S
