A mild and green electro-oxidative protocol to construct aromatic esters from methylarenes and alcohols is herein reported. Importantly, the reaction is free of metals, chemical oxidants, bases, acids, and operates at room temperature. Moreover, the design of the electrolyte was found critical for the oxidation state and structure of the coupling products, a rarely documented effect. This electro-oxidative coupling process also displays exceptional tolerance of many fragile easily oxidized functional groups such as hydroxy, aldehyde, olefin, alkyne, as well as neighboring benzylic positions. The enantiomeric enrichment of some chiral alcohols is moreover preserved during this electro-oxidative coupling reaction, making it overall a promising synthetic tool.

Multitarget directed ligands (MTDLs) are arising as promising tools to tackle complex diseases. The main goal of this work is to create powerful modulating agents for neurodegenerative disorders. To achieve this aim, we have combined fragments that inhibi

The endoplasmic reticulum (ER), as the largest organelle in eukaryotic cells, plays complex but pivotal roles in multiple intracellular metabolic functions, including biosynthesis, sensing, and signal transduction, especially in proteins folding and post-translation modification. The ER is regarded as a promising target for anticancer therapy. Based on previous tumor-targeted photodynamic therapy (PDT), we chemically modified the phthalocyanine-based photosensitizer molecule with the small molecular anticancer-targeting drug erlotinib and the ER-targetable moiety methyl sulfonamide to develop an advanced photosensitizer EB-ER-Pc that can specifically target the subcellular organelle ER of EGFR-overexpressing cancer cells. The in vitro experiments show that the dual-target photosensitizer EB-ER-Pc can generate ROS in situ in the ER of the tumor target region to induce ER stress, upregulate Ca2+ ion level, and decrease mitochondrial membrane potential (MMP) to mediate cancer cells death and ablation. The results suggest that EB-ER-Pc is a promising candidate for effective photodynamic cancer therapy.
