Synthesis of Sulfur Heterocycles by Palladium‐Catalyzed Cyclization

European Journal of Organic Chemistry, Volume 29, Issue 14, 15 April 2026.
In spite of the well‐known palladium thiophilicity, sulfur‐containing acyclic substrates may efficiently undergo several different kinds of palladium‐catalyzed cyclization processes leading to highly important sulfur heterocycles in one synthetic step. Advances in this challenging and stimulating field of research are presented in this review.

Design of Intrinsically Stable Hole‐Selective Self‐Assembled Monolayers by Introducing Fused‐Ring Intramolecular Donor–Acceptor Interactions

Angewandte Chemie, Volume 137, Issue 28, July 7, 2025.
Herein, we develop a novel SAM molecular design strategy by introducing fused‐ring intramolecular donor–acceptor (D–A) interactions. The designed molecule, JJ32, features a benzo[5,6][1,4]thiazino[2,3‐b]quinoxaline skeleton, where strong D–A interactions enhance charge delocalization and downshift the LUMO energy level.

Photo‐Rewritable Ambipolar Organic Electrochemical Synapses with Bidirectional Optical Plasticity for Adaptive Vision in Aqueous Environments

Advanced Materials, Volume 38, Issue 24, 27 April 2026.
Photo‐rewritable ambipolar organic synapses operating in aqueous environments at low voltage (≤0.4 V) demonstrate bidirectional optical plasticity through photon‐modulated electrochemical doping. The bulk heterojunction device enables both excitatory and inhibitory responses with extended retention time (>130 min).

The Contribution of Cholesterol and Squalene Synthase in Cancer: Molecular Mechanisms, Lipid Rafts and Therapeutic Approaches

Medicinal Research Reviews, Volume 46, Issue 2, Page 352-381, March 2026.
ABSTRACT A plethora of cellular signaling pathways are dysregulated in cancer cells, promoting carcinogenesis and migration. Cholesterol has recently been linked to cancer by several subcellular mechanisms, especially by its involvement in the formation of lipid rafts, which promote oncogenic signaling and cancer cell invasion. Squalene synthase (SQS),
