Article Synopsis
- The catalytic triad of RNase A, consisting of His12, Lys41, and His119, is crucial for cleaving RNA bonds and creates a positively charged environment at physiological pH.
- Docking studies identified a new class of RNase A inhibitors, 1,4,5-trisubstituted-carboxylated 1,2,3-triazoles, which were synthesized using pre-functionalized compounds under solvent and catalyst-free conditions.
- The synthesized inhibitors showed competitive inhibition with varying efficacy, with the most effective being bisthioglycolic acid and bisoxyacetic acid derivatives, demonstrating significant hydrogen bonding with RNase A and providing insights into the structure-activity relationship.
Design of Highly Conductive PILs by Simple Modification of Poly(epichlorohydrin--ethylene oxide) with Monosubstituted Imidazoles.

High ionic conductivity poly(ionic liquid)s (PILs) are of growing interest for their thermal and electrochemical stability, processability, and potential in safe, flexible all-solid-state electrochemical devices. While various approaches to enhance the ionic conductivity are reported, the influence of cation substituents is rarely addressed. Moreover, some of the asymmetric anions recently developed for high-conductivity ionic liquids were never tested in PILs.

NHC boryl radical mediated halogen atom transfer (XAT) is useful in organic synthesis. Yet, most of the reaction ends only with reducing the halogen to hydrogen, that is, the C-X to C-H. This is especially dominant for electron-deficient alkyl halides, where the formed electrophilic radical reacts rapidly with NHC boranes.

To overcome the worldwide environmental crisis related to the continuous emission of CO, the use of porous organic polymers, which are excellent absorbents and conversion materials, to reduce CO emission is of great significance. Among them, hyper-crosslinked polymers (HCPs) are porous materials with a high pore density that are synthesized using a simple one-pot method that is economical and can realized at a low temperature, hence they have good application prospects as adsorbents for CO. In this study, a batch of petroleum coke-based HCPs with different sulfur contents was prepared via the one-pot Friedel-Crafts alkylation reaction using inexpensive and abundant petroleum coke as raw material.

Although pollution during crude oil production has been paid attention, there is lack of studies on organic pollutants generated/emitted from oil-production wastewater (OPW) treatment processes, especially advanced oxidation process. Based on GC-Q-Orbitrap-HRMS, the present study performed non-target analysis of volatile/semi-volatile organic compounds in physical and electro-oxidation units of OPW treatment stations located in Shengli Oilfield of China. Overall, 64-227 organic compounds were respectively identified in different units, and electro-oxidation was found elevating (by 2.
