Fluorescence imaging is an important method in the field of biomedicine. Fluorescence imaging is nondestructive, has high efficiency and sensitivity, high resolution and allows real-time dynamic monitoring of living cells. However, it also has some disadvantages, such as high background signals and low selectivity. Bioorthogonal reactions, with the advantages of being both nondestructive and effective, are used to trace and analyze biological interactions in vivo. This review focuses on recent progress in understanding the mechanism of action of fluorescence probes.

This mini-review highlights some recent progress in the engineering of single-atom catalysts (SACs) through metal–organic frameworks (MOFs) and derivatives. The inherent molecular and chemical specificities within the MOFs and derivatives can offer stabilisation of the SACs with high atomic isolation and dispersion. As MOFs are often considered an infinite array of self-assembled molecular catalysts, specifically designed structures can provide further functionalities to suit the needs of different catalytic applications. In brief, we can divide the preparation approaches into three main categories: (1) fabrication onto functional groups of the ligands, (2) fabrication onto Lewis acid sites of nodal centres, and (3) synthesis via a pyrolysis-mediated technique. Through these approaches, strong metal–support interactions can be established to aid the fine-tuning of the catalytic properties. We also discuss how recent progress in the development of state-of-the-art microscopic, spectroscopic, and crystallographic techniques has enabled scientists to elucidate the structure–activity relationship.

COVID-19 has broken out rapidly in nearly all countries worldwide, and has blossomed into a pandemic. Since the beginning of the spread of COVID-19, many scientists have been cooperating to study a vast array of old drugs and new clinical trial drugs to discover potent drugs with anti-COVID-19 activity, including antiviral drugs, antimalarial drugs, immunosuppressants, Chinese medicines, Mpro inhibitors, JAK inhibitors, etc. The most commonly used drugs are antiviral compounds, antimalarial drugs and JAK inhibitors. In this review, we summarize mainly the antimalarial drugs chloroquine and hydroxychloroquine, the antiviral drugs Favipiravir and Remdesivir, and JAK inhibitor Ruxolitinib, discussing their biological activities, clinical trials and synthesis progress.

In recent years, the incorporation of molecular enzymes into nanostructured frameworks to create efficient energy conversion biomaterials has gained increasing interest as a promising strategy owing to both the dynamic behavior of proteins for their electrocatalytic function and the unique properties of the synergistic interactions between proteins and nanosized materials. Herein, we review the impact of proteins on energy conversion fields and the contribution of proteins to the improved activity of the resulting nanocomposites. We address different strategies to fabricate protein-based nanocatalysts as well as current knowledge on the structure–function relationships of enzymes during the catalytic processes. Additionally, a comprehensive review of state-of-the-art bioelectrocatalytic materials for water-splitting reactions such as hydrogen evolution reaction (HER) and oxygen evolution reactions (OER) is afforded. Finally, we briefly envision opportunities to develop a new generation of electrocatalysts towards the electrochemical reduction of N2 to NH3 using theoretical tools to built nature-inspired nitrogen reduction reaction catalysts.

8-Aminoquinoline is a common nitrogen-containing heterocyclic framework in many natural products, functional materials and useful drugs. It has been developed as a powerful bidentate directing group or ligand auxiliary in the field of C–H bond activation/functionalization in recent years. In this context, the synthesis of substituted 8-aminoquinoline is of great importance. In this review we focus on the functionalization of positions C2–C7 on the 8-aminoquinoline ring, which involves the formation of C–C and C–Z (Z?=?heteroatom) bonds by transition metal catalysts, photocatalysts or metal-free conditions. Mechanistically, a single electron transfer (SET) pathway is suggested in most cases.
8-氨基喹啉是许多天然产物、功能材料和有用药物中常见的含氮杂环骨架。近年来,它作为一种强有力的双齿导向基团或配体助剂在碳-氢键激活/功能化领域得到了发展。在此背景下,取代8-氨基喹啉的合成具有重要意义。本文综述了8-氨基喹啉环上C2-C7位的官能化,包括在过渡金属催化剂、光催化剂或无金属条件下形成C-C和C-Z (Z =?杂原子)键。在大多数情况下,单电子转移(SET)途径被认为是可行的。

DNA and protein are the most important two classes of biomacromolecules forming the basis of life. The conjugation of the two using crosslinking chemistries enables a combination of molecular recognition, enzymatic catalysis, and Watson–Crick hybridization properties. The DNA–protein conjugate with combined properties enables a broad range of applications, such as sensitive and selective bioassays, therapeutic agents, and building blocks for programmable nanoassemblies. In this review, we survey the conjugates from the aspects of conjugation chemistries as well as applications in biomedical and nanotechnology fields. We highlight the functions of both biological moieties of a conjugate for target binding and signal transduction in bioassays. We also review the use of DNA–protein conjugates for the construction of a variety of functional and dynamic nanostructures, from isolated hybrid cages to three-dimensional (3D) protein crystalline lattices. Moreover, these conjugates have been used as carriers to deliver enzymes or functional nucleic acids for disease treatments and gene editing.
