The article was written by Guo, Ying; Wang, Wei David; Li, Shengyu; Zhu, Yin; Wang, Xiaoyu; Liu, Xiao; Zhang, Yuan. The article contains the following contents:

The properties of high stability, periodic porosity, and tunable nature of ordered mesoporous polymers make these materials ideal catalytic nanoreactors. However, their application in organocatalysis has been rarely explored. We report herein for the first time the incorporation of a versatile organocatalyst, 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO), into the pores of an FDU-type mesoporous polymer via a pore surface engineering strategy. The resulting FDU-15-TEMPO possesses a highly ordered mesoporous organic framework and enhanced stability, and shows excellent catalytic activity in the selective oxidation of alcs. and aerobic oxidative synthesis of 2-substituted benzoxazoles, benzimidazoles and benzothiazoles. Moreover, the catalyst can be easily recovered and reused for up to 7 consecutive cycles. In the experiment, the researchers used 3-Pyridinemethanol(cas: 100-55-0Reference of 3-Pyridinemethanol)

Name: 4-Aminobutan-1-olIn 2019 ,《Highly sensitive fluorescent bioassay of 2,3,7,8-tetrachloro-dibenzo-p-dioxin based on abnormal expression of cytochrome P450 1A2 in human cells》 was published in Analytica Chimica Acta. The article was written by Shangguan, Li; Wei, Yuanqing; Wang, Kan; Zhang, Yuanjian; Liu, Songqin. The article contains the following contents:

Current in vitro bioassays of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD, a major threat carcinogen) are relied on murine cells and fluorescent probe 7-ethoxyresorufin (7-ER), in which TCDD mostly causes abnormal expression of cytochrome P 450 1A1 (CYP1A1). However, for human cells, TCDD mainly leads to a distinct abnormal expression of cytochrome P 450 1A2 (CYP1A2). The poor response of 7-ER to CYP1A2 limits the traditional bioassay for human cells. Herein, we report a fluorescent probe N-(3-hydroxybutyl)-4-methoxy-1,8-naphthalimide (HBMN) for in vitro bioassay of TCDD with human cells. HBMN had ca. 60 times higher affinity to CYP1A2 than 7-ER. As such, the sensing sensitivity increased by 10 times, and different expression of CYP1A2 by TCDD induction in different human cells was found. Besides, HBMN was also feasible in rapid screening of TCDD concentration by naked eye. It would open a new way to highly sensitive detect TCDD and understand the pathogenesis of TCDD in different human organs.

Recommanded Product: 34374-88-4This research focused onzinc air battery iron nitrogen doped mesoporous carbon; covalent organic framework oxygen reduction electrocatalyst. The article conveys some information:

The rational design and synthesis of mesoporous functional materials is of great significance to tackle fundamental challenges in materials science and to yield practical solutions for efficient energy utilization. Here, a novel p-toluenesulfonic acid-assisted mechanochem. approach is used to prepare a silica-templated bipyridine-containing covalent organic framework (COF), which can be further converted into an iron-nitrogen-doped mesoporous carbon (mC-TpBpy-Fe) upon carbonization and template removal. The resulting mC-TpBpy-Fe exhibits a large pore volume and surface area, which significantly promote the mass transfer efficiency and increase the accessibility of the active sites, yielding a high ORR activity with a competitive half-wave potential of 0.845 V and limiting c.d. of 5.92 mA/cm2 (vs 0.852 V and 5.57 mA/cm2 for Pt/C). Application of this COF derived mesoporous carbon within a Zn-air battery revealed that it can operate in ambient conditions with a competitive discharge performance, showing its potential for practical applications.

《Structure-function studies of the aminothiol radioprotectants. Effect of carbon chain length in mercaptoethylamine homologs》 was published in Radiation Research in 1971. These research results belong to Swartz, Harold M.; Copeland, Edmund S.; Richardson, Earl C.. COA of Formula: C5H14ClNS The article mentions the following:

A study of the relation between chemical structure of aminothiols such as β-mercaptoethylamine-HCl (I) and its propyl, butyl, pentyl, and hexyl homologs, and the phys. chem. radiation protection in Escherichia coli which were irradiated in the presence of 0.1M protectant at either 1°C or 77°K and equilibrated with 100% O2 or N2 prior to irradiation showed that in contrast to mammalian systems no abrupt reduction in radioprotection occurred when the carbon chain separating amino acids and thiol groups was lengthened from 3 to 4 or more units. Free radical studies which were observed by ESR spectroscopy of treated bacteria preparations irradiated at 77°K and bacteriolog. studies indicated a gradual decrease in efficiency with no change in the mechanism of action either in O2 or N2. These results suggest a protective effect of aminothiols by specific interactions with cell components in addition to acting via a more general, non-specific radical scavenging and (or) repair mechanism. The experimental process involved the reaction of 5-Aminopentane-1-thiol hydrochloride(cas: 31110-78-8COA of Formula: C5H14ClNS)

《Unusual Reactivity and Metal Affinity of Water-Soluble Dipyrrins》 was written by El Khatib, Mirna; Cheprakov, Andrei V.; Vinogradov, Sergei A.. Recommanded Product: 26153-38-8This research focused onwater soluble dipyrrin preparation metal affinity. The article conveys some information:

The primary goal of the study was to evaluate dipyrrins functionalized with ester and amide groups in 2,2′-positions in sensing applications. While developing the synthesis, it was found that 3,3′,4,4′-tetraalkyldipyrrins 2,2′-diesters as well as 2,2′-diamides can undergo facile addition of water at the meso-bridge, transforming into colorless meso-hydroxydipyrromethanes. Spectroscopic and computational investigation revealed that this transformation proceeds via dipyrrin cations, which exist in equilibrium with the hydroxydipyrromethanes. While trace amounts of acid favor conversion of dipyrrins to hydroxydipyrromethanes, excess acid shifts the equilibrium toward the cations. Similarly, the presence of Zn2+ facilitates elimination of water from hydroxydipyrromethanes with chromogenic regeneration of the dipyrrin system. In organic solutions in the presence of Zn2+, dipyrrin-2,2′-diesters exist as mixtures of mono-(LZnX) and bis-(L2Zn) complexes. In L2Zn, the dipyrrin ligands are oriented in a nonorthogonal fashion, causing strong exciton coupling. In aqueous solutions, dipyrrins bind Zn2+ in a 1:1 stoichiometry, forming mono-dipyrrinates (LZnX). Unexpectedly, dipyrrins with more electron-rich 2,2′-carboxamide groups revealed ~20-fold lower affinity for Zn2+ than the corresponding 2,2′-diesters. D. Functional Theory (DFT) calculations with explicit inclusion of water reproduced the observed trends and allowed to trace the low affinity of the dipyrrin-diamides to the stabilization of the corresponding free bases via hydrogen bonding with water mols. Overall, the results reveal unusual trends in the reactivity of dipyrrins and provide clues for the design of dipyrrin-based sensors for biol. applications.3,5-Dihydroxybenzaldehyde(cas: 26153-38-8Recommanded Product: 26153-38-8) was used in this study.
