The N -Alkylation of Agelastatin A Modulates Its Chemical Reactivity.
Publication Type: Academic Journal
Source(s): Molecules. Oct2023, Vol. 28 Issue 19, p6821. 13p.
Abstract: Agelastatin A is a marine alkaloid with potent biological activity. To date, at least 17 different strategies have achieved its total synthesis, along with many analogues. The present study focuses on the acidity stability of some N-methyl derivatives ...
Competitive Chemical Reaction Kinetic Model of Nucleosome Assembly Using the Histone Variant H2A.Z and H2A In Vitro.
Publication Type: Academic Journal
Source(s): International Journal of Molecular Sciences. Nov2023, Vol. 24 Issue 21, p15846. 14p.
Abstract: Nucleosomes not only serve as the basic building blocks for eukaryotic chromatin but also regulate many biological processes, such as DNA replication, repair, and recombination. To modulate gene expression in vivo, the histone variant H2A.Z can be dyna...
Time Crystal Synthon: The Way to Integrate Cascade Reactions for Advancing Multistep Flow Synthesis.
Publication Type: Academic Journal
Source(s): ChemEngineering. Oct2023, Vol. 7 Issue 5, p88. 12p.
Abstract: Multistep flow catalytic reactions in organic chemistry integrate multiple sequential organic reactions to enhance cost-efficiency, time management, and labour resources, all while boosting effectiveness and environmental sustainability. Similar to how...
Enthalpy-entropy compensation in the slow Arrhenius process.
Publication Type: Academic Journal
Source(s): Journal of Chemical Physics. 10/28/2023, Vol. 159 Issue 16, p1-6. 6p.
Abstract: The Meyer–Neldel compensation law, observed in a wide variety of chemical reactions and other thermally activated processes, provides a proportionality between the entropic and the enthalpic components of an energy barrier. By analyzing 31 different po...
Advanced Self-Healing Ceramics with Controlled Degradation and Repair by Chemical Reaction.
Publication Type: Academic Journal
Source(s): Materials (1996-1944). Oct2023, Vol. 16 Issue 19, p6368. 8p.
Abstract: Controlling the chemical reaction rate concerning degradation and repair is found to be important to design advanced self-healing ceramics. The recovery and degradation behaviors of strength and stiffness were investigated by exposing aqueous solutions...
Mixer Design and Flow Rate as Critical Variables in Flow Chemistry Affecting the Outcome of a Chemical Reaction: A Review.
Publication Type: Academic Journal

Abstract: Flow chemistry offers several advantages for performing chemical reactions and has become an important area of research. It may seem that sufficient knowledge has already been acquired on this topic to understand how to choose the design of microreacto...
Structural Fluctuation, Relaxation, and Folding of Protein: An Approach Based on the Combined Generalized Langevin and RISM/3D-RISM Theories.
Publication Type: Academic Journal
Source(s): Molecules. Nov2023, Vol. 28 Issue 21, p7351. 19p.
Abstract: In 2012, Kim and Hirata derived two generalized Langevin equations (GLEs) for a biomolecule in water, one for the structural fluctuation of the biomolecule and the other for the density fluctuation of water, by projecting all the mechanical variables i...
A chemical reaction network implementation of a Maxwell demon.
Publication Type: Academic Journal
Source(s): Journal of Chemical Physics. 11/28/2023, Vol. 159 Issue 20, p1-14. 14p.
Abstract: We study an autonomous model of a Maxwell demon that works by rectifying thermal fluctuations of chemical reactions. It constitutes the chemical analog of a recently studied electronic demon. We characterize its scaling behavior in the macroscopic limi...
Bioconvection Flow in the Presence of Casson Nanoparticles on a Stretching/Shrinking Vertical Sheet with Chemical Reaction.

Abstract: A Casson nanoparticle is used in this study to investigate the effects of toxic reactions, temperatures, and concentrations on convective heat transfer flow across a stretching/shrinking vertical sheet. The goal is to convert the control linear partial...
Nonequilibrium interfacial properties of chemically driven fluids.
Publication Type: Academic Journal
Source(s): Journal of Chemical Physics. 2023, Vol. 159 Issue 15, p1-14. 14p.
Abstract: Chemically driven fluids can demix to form condensed droplets that exhibit phase behaviors not observed at equilibrium. In particular, nonequilibrium interfacial properties can emerge when the chemical reactions are driven differentially between the in...
