Silent Partners in the Mill: Unveiling the Role of Additives in Mechanochemical Synthesis

Chemistry – A European Journal, EarlyView.
Mechanochemistry offers a sustainable, solvent‐free alternative to traditional synthesis, often enhanced by additives in a process known as additive‐assisted grinding. This review discusses how various additives, including liquids, ionic solids, and advanced materials like ionic liquids and piezoelectric compounds, improve reaction efficiency ...

High‐Throughput Synthesis and Screening of a Cyanimide Library Identifies Selective Inhibitors of ISG15‐Specific Protease mUSP18

Angewandte Chemie, Volume 137, Issue 49, December 1, 2025.
Deubiquitinases (DUBs) and Ub‐like proteases are attractive but challenging drug targets. We developed a high‐throughput synthesis method and prepared a 7536‐member cyanimide DUB‐targeted compound library in 1536‐well plates, using Echo acoustic dispensing. Screening yielded a selective, 35 nM inhibitor of mUSP18, the main ISG15 protease.

Concise Synthesis of Macrocycles by Multicomponent Reactions [PDF]

, 2018
A short reaction pathway was devised to synthesize a library of artificial 18-27-membered macrocycles. The five-step reaction sequence involves ring opening of a cyclic anhydride with a diamine, esterification, coupling with an amino acid isocyanide ...

Self-assembly of minimal peptoid sequences [PDF]

, 2020
Peptoids are biofunctional N-substituted glycine peptidomimics. Their self-assembly is of fundamental interest because they demonstrate alternatives to conventional peptide structures based on backbone chirality and beta-sheet hydrogen bonding.

NMR‐Based Structural Analysis of Highly Substituted Pyridines From Kondrat'eva Aza‐Diels–Alder Cycloadditions

Magnetic Resonance in Chemistry, EarlyView.
We report the results from a kinetic and mechanistic investigation of an inverse‐electron‐demand Diels–Alder (IEDDA) cycloaddition involving an oxazole‐type diene synthesized via an Ugi–Zhu multicomponent reaction (UZ‐3CR). ABSTRACT Pyridines are a crucial class of heterocycles with widespread applications in natural products, pharmaceuticals, and ...
