Han, Jingjing;Li, Haidong;Zhao, Luyang;Kim, Gyoungmi;Chen, Yahui;Yan, Xuehai;Yoon, Juyoung research published 《 Albumin-mediated “Unlocking” of supramolecular prodrug-like nanozymes toward selective imaging-guided phototherapy》, the research content is summarized as follows. Construction of an activatable photosensitizer and integration into an adaptive nanozyme during phototherapy without producing off-target toxicity remains a challenge. Herein, we have fabricated a prodrug-like supramol. nanozyme based on a metallic-curcumin and cyanine co-assembly. The albumin-mediated phenol AOH group transformation of nanozyme changes its adjustable oxygen stress from neg. superoxide dismutase-like activity of ROS-scavenging to pos. photo oxidase activity with an ROS-amplifying capacity. It further increases the depth penetration of a nanozyme in a tumor spheroid, selectively targeting tumorous phototherapy. It also triggers a signal in targeted tumor cells and helps increase cancer cell ablation. This work suggests new options for development of activatable supramol. nanozymes and provides a synergetic prodrug-like nanozyme strategy for early diagnosis and preclin. phototherapeutics.

The compound is characterized by spectrometric, spectroscopic and single crystal (SC-XRD) techniques. Non-covalent interactions that are responsible for crystal packing are explored by Hirshfeld surface anal. All theor. calculations were performed by DFT quantum chem. methods using 6-311G(d,p) and cc-pVTZ basis sets and compared. Theor. harmonic frequencies of Et 2-[2-(2-nitrobenzylidene)hydrazinyl]thiazole-4-carboxylate were optimized. Confirmation of hydrogen bonding sites was analyzed by mol. electrostatic potential (MEP) and Mulliken population anal. The vibrational frequencies of characteristic functional groups and chem. shifts were found in good agreement with exptl. assignments.

In addition, compounds I and II had negligible cytotoxicity in mammalian cells (CC₅₀ values > 50μM). Also noteworthy is the examination of the cell death mechanism of T. cruzi, which showed that compound III induced necrosis and apoptosis in the parasite. SEM anal. demonstrated that the treatment of Trypanosoma cruzi trypomastigote cells with the compound III at different IC₅₀ concentrations promoted alterations in the shape, flagella and body surface, inducing parasite death. Together, the data revealed a novel series of 1,3-thiazole structure-based compounds I with promising activity against Trypanosoma cruzi and Leishmania spp., broadening ways for scaffold optimization.

Gu, Ruirui;Lehn, Jean-Marie research published 《 Constitutional Dynamic Selection at Low Reynolds Number in a Triple Dynamic System: Covalent Dynamic Adaptation Driven by Double Supramolecular Self-Assembly》, the research content is summarized as follows. A triple dynamic complex system has been designed, implementing a dynamic covalent process coupled to two supramol. self-assembly steps. To this end, two dynamic covalent libraries (DCLs), DCL-1 and DCL-2, have been established on the basis of dynamic covalent C=C/C=N organo-metathesis between two Knoevenagel derivatives and two imines. Each DCL contains a barbituric acid-based Knoevenagel constituent that may undergo a sequential double self-organization process involving first the formation of hydrogen-bonded hexameric supramol. macrocycles that subsequently undergo stacking to generate a supramol. polymer SP yielding a viscous gel state. Both DCLs display selective self-organization-driven amplification of the constituent that leads to the SP. Dissociation of the SP on heating causes reversible randomization of the constituent distributions of the DCLs as a function of temperature Furthermore, diverse distribution patterns of DCL-2 were induced by modulation of temperature and solvent composition The present dynamic systems display remarkable self-organization-driven constitutional adaptation and tunable composition by coupling between dynamic covalent component selection and two-stage supramol. organization. In more general terms, they reveal dynamic adaptation by component selection in low Reynolds number conditions of living systems where frictional effects dominate inertial behavior.

The Ritter reaction has been recognized as an elegant strategy to construct the C-N bond. Its key feature is forming the carbocation for nucleophilic attack by nitriles. Herein, authors report a complementary visible-light-induced three-component Ritter reaction of alkenes, nitriles, and α-bromo nitriles/esters, thereby providing mild and rapid access to various γ-amino nitriles/acids.

Gunter, Kevin;Sorci, Mirco;Belfort, Georges research published 《 A Simplified Predictive Tool for Design and Analysis of SET-LRP Reactions with Mechanistic Insight》, the research content is summarized as follows. Single-electron transfer (SET)-living radical polymerization (LRP) is a robust, fast, “green,” grafting method, similar but different from atom transfer radical polymerization, that operates at ambient temperature in the presence of oxygen and is industrially attractive. Solving a simplified reaction model with only five rather than 12 reactions in solution, for describing the SET-LRP scheme and verifying it with exptl. data, we provide (i) a useful tool to predict conversion given initial conditions and rate constants, and (ii) key mechanistic insights with a parametric sensitivity anal., illustrating the effects of initial conditions, kinetic rate constants, temperature, and copper particle size. Findings include: (i) Increasing the formation rate of radicals (i.e., k_act) exhibited a maximum in monomer conversion. (ii) The optimal ratio of initial conditions was found to be [MA]₀/[P_nX]₀/[Cu^IIX₂/L]₀ = 222/1/1.5, where [MA]₀ = 7.4 M. (iii) Increasing the temperature strongly improved monomer conversion with an inflection point. (iv) Using an order-of-magnitude and Damköhler number anal., we provide a rationale for selecting small diameter particles and specify how they are likely to perform with SET-LRP reactions. Assumptions of the model include: Solid copper concentration was an infinite source of dissolved Cu^I and Cu^II and was available instantaneously (with Damkohler number ≪ 1, for reaction rather than diffusion limitation). Also, the reverse reaction of the disproportionation of Cu^I was negligible, polymer chain length did not affect reaction kinetics, and all intermediate reactions were neglected.
