Recent Developments

The introduction of a halogen atom into a small molecule can effectively modulate its properties, yielding bioactive substances of agrochemical and pharmaceutical interest. Consequently, the development of selective halogenation strategies is of high technological value. Besides chemical methodologies, enzymatic halogenations have received increased interest as they allow the selective installation of halogen atoms in molecular scaffolds of varying complexity under mild reaction conditions. Today, a comprehensive library of aromatic halogenases exists, and enzyme as well as reaction engineering approaches are being explored to broaden this enzyme family’s biocatalytic application range. In this review, we highlight recent developments in the sourcing, engineering, and application of flavin-dependent halogenases with a special focus on chemoenzymatic and coupled biosynthetic approaches.

Metallo-β-lactamases (MBLs) are a family of Zn(II)-dependent enzymes that can hydrolyze almost all β-lactam antibiotics. Horizontal transfer of the genes encoding MBLs among Gram-negative bacteria pathogens has led to the emergence of extensively drug-resistant pathogens, which now represent a major threat to human health. As there is not to date yet a clinically available MBL inhibitor, the discovery of new MBL inhibitors has great urgency. This review highlights the recent developments in the discovery of small-molecule MBL inhibitors.

Abstract Squaraine (SQ) dyes are an important class of electron-donating (donors or p-type) semiconductors for organic solar cells (OSC) due to their facile synthetic access, broad optical absorption with high oscillator strengths, and chemical robustness. Blending them with compatible electron-acceptors (acceptors or n-type) yields OSC devices known as bulk-heterojunction (BHJ) small molecule donor organic solar cells (SMD-OSCs). Through extensive research on materials design, synthesis, characterization, and device optimization over the past ˝ve years, SMD-OSCs employing SQ-based structures have achieved remarkable increases in device power conversion e˚ciency (PCE), now approaching 8%. Although these PCEs have not yet equaled the performance of state- of-the art donor polymers and some other SMD semiconductors, SQ-based OSC progress highlights successful and generalizable strategies for small molecule solar cells that should lead to future advances. In this review, recent developments in SQ-based OSCs are discussed and analyzed.
