A dual-functional supramolecular assembly for enhanced photocatalytic hydrogen evolution was written by Qin, Lin;Wang, Ruijie;Xin, Xing;Zhang, Mo;Liu, Tianfu;Lv, Hongjin;Yang, Guo-Yu. And the article was included in Applied Catalysis, B: Environmental in 2022.SDS of cas: 38215-36-0 The following contents are mentioned in the article:

The construction of multifunctional supramol. assembly is a central research interest in solar-driven water splitting to hydrogen. We here report the successful preparation of a dual-functional supramol. assembly via facile electrostatic integration of a pos.-charged Ir-based chromophore and a neg.-charged nickel-substituted polyoxometalate catalyst. The resulting dual-functional supramol. can form ordered vesicle-like assemblies and work efficiently as both light-absorber and catalyst for hydrogen production under visible light irradiation Under minimally optimized conditions, a catalytic hydrogen production turnover number of over 4000 was achieved after 96-h irradiation, which is 17 times to that of discrete components under otherwise identical conditions. Destruction of such ordered vesicle-like assemblies will lead to a remarkable decrease of photocatalytic hydrogen production activity. Mechanistic studies further revealed the presence of both oxidative and reductive quenching processes during photocatalysis and also confirmed that the formation of ordered supramol. is beneficial for effective electron transfer between chromophore and catalyst. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0SDS of cas: 38215-36-0).

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 nitrogen in thiazole is sp2 hybridized and the lone pair of electrons localized on the nitrogen is less reactive due to increased aromatic character and decreased basicity. It is protonated and alkylated/acylated at nitrogen forming hydrochloride and quaternary thiazolium salt.SDS of cas: 38215-36-0

Alginate-Based Amphiphilic Block Copolymers as a Drug Codelivery Platform was written by Feng, Yunpeng;Quinnell, Sean P.;Lanzi, Alison M.;Vegas, Arturo J.. And the article was included in Nano Letters in 2021.Safety of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one The following contents are mentioned in the article:

Structured nanoassemblies are biomimetic structures that are enabling applications from nanomedicine to catalysis. One approach to achieve these spatially organized architectures is utilizing amphiphilic diblock copolymers with one or two macromol. backbones that self-assemble in solution To date, the impact of alternating backbone architectures on self-assembly and drug delivery is still an area of active research limited by the strategies used to synthesize these multiblock polymers. Here, we report self-assembling ABC-type alginate-based triblock copolymers with the backbones of three distinct biomaterials utilizing a facile conjugation approach. This “polymer mosaic” was synthesized by the covalent attachment of alginate with a PLA/PEG diblock copolymer. The combination of alginate, PEG, and PLA domains resulted in an amphiphilic copolymer that self-assembles into nanoparticles with a unique morphol. of alginate domain compartmentalization. These particles serve as a versatile platform for co-encapsulation of hydrophilic and hydrophobic small mols., their spatiotemporal release, and show potential as a drug delivery system for combination therapy.

TP53 inhibitor PFTα increases the sensitivity of arsenic trioxide in TP53 wildtype tumor cells was written by Wang, Haiwei;Wang, Xinrui;Xu, Liangpu;Zhang, Ji. And the article was included in FEBS Open Bio in 2022.Electric Literature of C16H19BrN2OS The following contents are mentioned in the article:

Arsenic trioxide (ATO) has been shown to be effective in treating acute promyelocytic leukemia. TP53 mutated/null tumor cells are more sensitive to ATO treatment compared to tumor cells carrying wildtype TP53 gene copies. However, it is unclear whether TP53 inhibitors can increase the sensitivity of TP53 wildtype tumor cells to ATO. Here we show that breast, colon, and lung cancer cell lines with mutated/null TP53 are more sensitive to ATO-induced cell growth inhibition than cells with wildtype TP53. Moreover, inhibition of TP53 by a TP53 inhibitor, PFTα, increased the ATO sensitivity of TP53 wildtype tumor cells, coincident with ATO-induced cell growth arrest and cell apoptosis. Furthermore, combined treatment with ATO and PFTα synergistically inhibited tumor growth in mouse xenografts in vivo. Through microarray transcriptional anal., we found that ATO-regulated genes were associated with TP53 and cell cycle signaling pathways. Cotreatment with PFTα enhanced ATO-induced dynamic transcriptional changes. Overall, our results provide evidence for using TP53 chem. inhibitors to enhance the ATO-mediated therapeutic response against TP53 wildtype tumor cells.

Pifithrin-α alters p53 post-translational modifications pattern and differentially inhibits p53 target genes was written by Zhu, Jiawei;Singh, Madhurendra;Selivanova, Galina;Peuget, Sylvain. And the article was included in Scientific Reports in 2020.Recommanded Product: 63208-82-2 The following contents are mentioned in the article:

Pifithrin-α (PFT-α) is a small mol. which has been widely used as a specific inhibitor of p53 transcription activity. However, its mol. mechanism of action remains unclear. PFT-α has also been described to display potent p53-independent activity in cells. In this study, we addressed the mechanism of action of PFT-α. We found that PFT-α failed to prevent the effects of Mdm2 inhibitor Nutlin-3 on cell cycle and apoptosis in several cancer cell lines. However, PFT-α rescued normal primary fibroblasts from growth inhibition by Nutlin-3. PFT-α displayed a very limited effect on p53-dependent transcription upon its activation by Nutlin-3. Moreover, PFT-α inhibitory effect on transcription was highly dependent on the nature of the p53 target gene. PFT-α attenuated post-translational modifications of p53 without affecting total p53 protein level. Finally, we found that PFT-α can decrease the level of intracellular reactive oxygen species through activation of an aryl hydrocarbon receptor (AHR)-Nrf2 axis in a p53-independent manner. In conclusion, PFT-α inhibits only some aspects of p53 function, therefore it should be used with extreme caution to study p53-dependent processes.

The direct use of the most sustainable energy, the sun, for chem. reactions is extremely attractive. This study proposes a green luminescent concentrator-based photo-microreactor (GLC-PM) assembled by flow modules that can be diversely 3D-printed using a photocurable fluoropolymer formulated with a fluorescent dye (Coumarin 6) for enhancing photochem. reactions. The inherently solvent-resistant GLC-flow modules maintain the chem. efficiency without leaching of fluorescent dyes and deposition of photocatalyst on the walls. In particular, the hexagonal GLC modules enable facile assembly into the customized PMs based on the synthesis requirements using built-in magnets for one-touch self-alignment. Moreover, the serially assembled GLC-PM was shown to enhance the photocatalytic reaction of C-C bond formation in the presence of Rose Bengal, and eventually, the GLC-PM formed by clustering serial and radial connections resulted in enhanced conversion and throughput of C-P bond formation in the presence of Eosin-Y. Therefore, the clustered GLC-PM can be considered as a viable and unique scaling strategy for the production of organic compounds, such as a photo-driven mini-plant.

The development of novel imaging agents for fluorescence detection of latent fingerprint is still important for criminal investigation and identity recognition. Herein, we reported a simple and robust method to prepare multi-color conjugated polymer micelles for visualization of fingerprints. A conjugated polyelectrolyte, poly[(9,9-bis(3′-((N,N-dimethyl)-N-ethylammonium)-propyl)-2,7-fluorene)-alt-2,7-(9,9-dioctylfluorene)] (PFN), was dissolved in water forming polymer micelles with blue emission. Green and red emissions were facilely achieved by incorporating small organic fluorophores including coumarin 6 (C6) and Nile red (NR) into the PFN micelles, resp. These micelles exhibited bright fluorescence both in solution and solid film, where significant aggregation-caused quenching was avoided and fluorescence resonance energy transfer from PFN to C6 or NR was enhanced. Through a simple solution method, these polymer micelles proved their high affinity towards the fingerprint ridges. Accordingly, fluorescent fingerprint images with high-resolution were obtained, which were less interfered by fluorescence background from substrate and overlap between adjacent fingerprints.

A novel self-coated polydopamine nanoparticle for synergistic photothermal-chemotherapy was written by Chen, Huan;Chen, Huali;Wang, Yiwu;Bai, Yan;Yuan, Pei;Che, Zhanghong;Zhang, Liangke. And the article was included in Colloids and Surfaces, B: Biointerfaces in 2021.COA of Formula: C20H18N2O2S The following contents are mentioned in the article:

The combination of photothermal therapy (PTT) and chemotherapy is a promising strategy to overcome the shortcomings of monotherapy. For the first time, we designed a self-coated nanoparticle formed by mesoporous polydopamine (MPDA) core and polydopamine (PDA) shell, which was used to load docetaxel and modified with hyaluronic acid (HA). The obtained nanoparticle can achieve targeted drug delivery and further exert the synergistic effect of PTT and chemotherapy. The MPDA core has high drug loading due to mesopores, and the PDA shell can prevent the drug from releasing in the non-target-site because of the pH-sensitivity of the PDA. Compared with other PDA coated nanoparticle, self-coated nanoparticle has a simpler composition and can avoid the potential toxicity caused by the introduction of other materials. Exptl. results showed that it had good photothermal conversion ability both in vivo and in vitro, and could be actively targeted into tumor cells through HA-mediated targeting. Under laser irradiation, it ablated the tumors. Simple ingredient and preparation, good compatibility and obvious therapeutic effect make it have a broad application prospect in tumor therapy.

Multicolor Light Mixing in Optofluidic Concave Interfaces for Anticounterfeiting with Deep Learning Authentication was written by Wang, Chenlu;Yan, Zhiyuan;Gong, Chaoyang;Xie, Hui;Qiao, Zhen;Yuan, Zhiyi;Chen, Yu-Cheng. And the article was included in ACS Applied Materials & Interfaces in 2022.Safety of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one The following contents are mentioned in the article:

Anticounterfeiting technol. has received tremendous interest for its significance in daily necessities, medical industry, and high-end products. Confidential tags based on photoluminescence are one of the most widely used approaches for their vivid visualization and high throughput. However, the complexity of confidential tags is generally limited to the accessibility of inks and their spatial location; generating an infinite combination of emission colors is therefore a challenging task. Here, we demonstrate a concept to create complex color light mixing in a confined space formed by microscale optofluidic concave interfaces. Infinite color combination and capacity were generated through chaotic behavior of light mixing and interaction in an ininkjet-printed skydome structure. Through the chaotic mixing of emission intensity, wavelength, and light propagation trajectories, the visionary patterns serve as a highly unclonable label. Finally, a deep learning-based machine vision system was built for the authentication process. The developed anticounterfeiting system may provide inspiration for utilizing space color mixing in optical security and communication applications.

Developing safe and efficient delivery vehicles for chemotherapeutic drugs has been a long-standing demanding. Amino acid-based polymers are promising candidates to address this challenge due to their excellent biocompatibility and biodegradation Herein, a series of well-defined amphiphilic block copolymers were prepared by PET-RAFT polymerization of N-acryloyl amino acid monomers. By altering monomer types and the block ratio of the copolymers, the copolymers self-assembled into nanostructures with various morphologies, including spheres, rod-like, fibers, and lamellae via hydrophobic and hydrogen bonding interactions. Significantly, the nanoparticles (NPs) assembled from amphiphilic block copolymers poly(N-acryloyl-valine)-b-poly(N-acryloyl-aspartic acid) (PV-b-PD) displayed an appealing cargo loading efficiency (21.8-32.6%) for a broad range of drugs (paclitaxel, doxorubicin (DOX), cisplatin, etc.) due to strong interactions.
