Strategic application of CuAAC click chemistry in the modification of natural products for anticancer activity

European Journal of Medicinal Chemistry Reports, 2023
Natural products play a key role in the history of human drug discovery, and especially for the anticancer agents. Copper(I)-catalyzed alkyne-azide [3+2] cycloaddition (CuAAC) reaction is perhaps the most powerful method for the efficient modification of

Generalizable Strategies for the Synthesis of Cereblon‐Recruiting PROTAC Prodrugs

Angewandte Chemie, EarlyView.
Cereblon‐recruiting PROTACs remain challenging to derivatize for prodrug‐based delivery. In this study, three complementary conjugation strategies enabled the efficient synthesis of cleavable PROTAC prodrugs with tunable release kinetics that can be incorporated into a library of PEGylated constructs and bottlebrush prodrugs.

Virus‐Mediated Self‐Assembly of Functional Cyclodextrins for Antiviral Inhibition

Angewandte Chemie, EarlyView.
A sialic acid (SA)‐functionalized cyclodextrin (CD) self‐assembles on SARS‐CoV‐2 through ligand–receptor recognition, nucleating cooperative supramolecular polymer growth that blocks infection. The adaptive assembly requires both ligand binding and host–guest polymerization, remains active across variants, and can be tuned by coassembly, establishing ...

A Lipid‐Conjugation Strategy for Intracellular Reactive Oxygen Species Control in Hepatic Cells

Angewandte Chemie, EarlyView.
A lipid conjugation strategy anchors a manganese Salen complex within phospholipid membranes, yielding stable, catalytically active liposomes. These lipid–metal assemblies efficiently degrade reactive oxygen species (ROS) and enable intracellular redox control in steatotic HepaRG cells, offering a precise route to biomimetic antioxidant design ...

Water‐Compatible SuFEx‐Active Diazonium Linchpin Platform for Rapid Modular Diversification and On‐DNA Functionalization

Advanced Functional Materials, EarlyView.
Sulfur fluoride exchange (SuFEx) is a powerful click platform, yet water‐compatible multifunctional linchpins remain elusive. Here, we report decagram‐scalable diazonium linchpins that enable rapid Pd‐catalyzed diversification and direct, catalyst‐free on‐DNA ligation in aqueous media.

Precision Switching and Coupled Motion in a [3]Rotaxane Molecular Machine

Angewandte Chemie, EarlyView.
A [3]rotaxane, composed by two crown ether macrocycles and an axle presenting three recognition sites, is operated through both chemical and electrochemical stimuli. The position of the macrocycles is precisely controlled by sequential stimulation and the processes are fully reversible. The characterization of the system revealed the macrocycles affect
