SDS of cas: 623-24-5 And the article was included in ChemSusChem in 2020. The article conveys some information:

The rapid growth of CO2 emissions, especially from power plants, has led to the urgent need to directly capture and fix CO2 in the flue gas after simple purification rather than energy-intensive gas separation Herein, imidazolium-functionalized ionic hypercrosslinked porous polymers (HCPs) bearing adjustable surface groups were straightforwardly synthesized through co-hypercrosslinking of benzylimidazole salts and crosslinker through Friedel-Crafts alkylation. Abundant microporosity and relatively high ionic moieties were obtainable in the ethyl-group-tethered ionic HCP, giving a remarkably selective CO2 capture performance with a CO2 uptake of 3.05 mmol g-1 and an ideal adsorbed solution theory (IAST) CO2/N2 selectivity as high as 363 (273 K, 1 bar). This ionic polymer demonstrated high efficiency in the synthesis of cyclic carbonates from the coupling of various epoxides with the simulated flue gas (15% CO2 and 85% N2), giving high yields, large turnover numbers (up to 4800), and stable reusability under additive- and solvent-free conditions. In the experimental materials used by the author, we found 1,4-Bis(bromomethyl)benzene(cas: 623-24-5SDS of cas: 623-24-5)

《Simultaneously boosting the conjugation, brightness and solubility of organic fluorophores by using AIEgens》 was written by Qi, Ji; Duan, Xingchen; Cai, Yuanjing; Jia, Shaorui; Chen, Chao; Zhao, Zheng; Li, Ying; Peng, Hui-Qing; Kwok, Ryan T. K.; Lam, Jacky W. Y.; Ding, Dan; Tang, Ben Zhong. Recommanded Product: 2,5-Dibromothiophene And the article was included in Chemical Science in 2020. The article conveys some information:

Organic near-IR (NIR) emitters hold great promise for biomedical applications. Yet, most organic NIR fluorophores face the limitations of short emission wavelengths, low brightness, unsatisfactory processability, and the aggregation-caused quenching effect. Therefore, development of effective mol. design strategies to improve these important properties at the same time is a highly pursued topic, but very challenging. Herein, aggregation-induced emission luminogens (AIEgens) are employed as substituents to simultaneously extend the conjugation length, boost the fluorescence quantum yield, and increase the solubility of organic NIR fluorophores, being favorable for biol. applications. A series of donor-acceptor type compounds with different substituent groups (i.e., hydrogen, Ph, and tetraphenylethene (TPE)) are synthesized and investigated. Compared to the other two analogs, MTPE-TP3 with TPE substituents exhibits the reddest fluorescence, highest brightness, and best solubility Both the conjugated structure and twisted conformation of TPE groups endow the resulting compounds with improved fluorescence properties and processability for biomedical applications. The in vitro and in vivo applications reveal that the NIR nanoparticles function as a potent probe for tumor imaging. This study would provide new insights into the development of efficient building blocks for improving the performance of organic NIR emitters.

Louwsma, Jeroen; Carvalho, Alain; Lutz, Jean-Francois; Joly, Stephane; Chan-Seng, Delphine published an article in 2021. The article was titled 《Adsorption of phenylalanine-rich sequence-defined oligomers onto Kevlar fibers for fiber-reinforced polyolefin composite materials》, and you may find the article in Polymer.Recommanded Product: 4-Bromobutanoic acid The information in the text is summarized as follows:

Oligomers comprising four or sixteen phenylalanine residues with regularly intercalated aliphatic chains of different lengths prepared by solid-phase synthesis exhibit sufficient thermal stability to be used as interfacial agents and processed for the preparation of poly(propylene-co-ethylene)-based composite materials. The investigation of their adsorption on Kevlar fibers by SEM is difficult due to the surface heterogeneity of the bare Kevlar fibers. However, oligomers with four successive phenylalanine residues have been clearly observed suggesting their better adsorption on the fiber. The quantification of those oligomers adsorbed on the fibers performed gravimetrically on pellets of fibers has however revealed no significant impact of the length of the aliphatic chain.4-Bromobutanoic acid(cas: 2623-87-2Recommanded Product: 4-Bromobutanoic acid) was used in this study.

4-Bromobutanoic acid(cas: 2623-87-2) belongs to carboxylic acids. The chief chemical characteristic of the carboxylic acids is their acidity.

In this study, the authors synthesized a series of amide and mitochondria-targeted derivatives with 3-O-acetyl-11-keto-β-boswellic acid (AKBA) as the parent structure and an ethylenediamine moiety as the link chain. Compound I, a mitochondrial-targeting potential derivative, showed significantly stronger antitumor activity than that of AKBA, and it could induce vacuolization of A549 cells and stimulate the production of reactive oxygen species (ROS) in a time- and concentration-dependent manner. The antioxidant N-acetylcysteine (NAC) could inhibit the ROS level but could not suppress vacuolization and cell death induced by I. Further studies demonstrated that I caused abnormal opening of mitochondrial permeability transition pore (MPTP) and a decrease of mitochondrial membrane potential; addnl., it caused cell cycle arrest in G0/G1 but did not induce apoptosis. I represents a compound with improved antiproliferative effects for cancer therapy working through new mechanisms.

The author of the article were Asay, Spencer; Graham, Andrew; Hollingsworth, Sydney; Barnes, Bradley; Oblad, Richard V.; Michaelis, David J.; Kenealey, Jason D.. The article conveys some information:

Prostate cancer is the second most commonly diagnosed cancer in men, and metastatic prostate cancer is currently incurable. Prostate cancer frequently becomes resistant to standard of care treatments, and the administration of chemotherapeutic drugs is often accompanied by toxic side effects. Combination therapy is one tool that can be used to combat therapeutic resistance and drug toxicity. Vitamin E (VE) compounds and analogs have been proposed as potential non-toxic chemotherapeutics. Here we modeled combination therapy using mixture design response surface methodol. (MDRSM), a statistical technique designed to optimize mixture compositions, to determine whether combinations of three chemotherapeutic agents: gamma-tocotrienol (gamma-T3), a-tocopherol ether acetate (a-TEA), and docetaxel (DOC), would prove more effective than docetaxel alone in the treatment of human prostate cancer cells. Response surfaces were generated for cell viability, and the optimal treatment combination for reducing cell viability was calculated We found that a combination of 20 uM gamma-T3, 30 uM a-TEA, and 25 nm DOC was most effective in the treatment of PC-3 cells. We also found that the combination of gamma-T3 and a-TEA with DOC decreased the amount of DOC required to reduce cell viability in PC-3 cells and ameliorated therapeutic resistance in DOC-resistant PC-3 cells.
