Mitochondrially targeted ceramides preferentially promote autophagy, retard cell growth, and induce apoptosis

Journal of Lipid Research, 2011
C6-pyridinium (d-erythro-2-N-[6′-(1′′-pyridinium)-hexanoyl]sphingosine bromide [LCL29]) is a cationic mitochondrion-targeting ceramide analog that promotes mitochondrial permeabilization and cancer cell death.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Total Syntheses of Agelamadin F and (±)‐Tauroacidin A, Enabled by NaClO2‐Mediated Coupling Reactions of Oroidin and Amines

Chemistry – A European Journal, EarlyView.
Total syntheses of agelamadin F and (±)‐tauroacidin A were achieved by sodium chlorite (NaClO2)‐mediated oxidative C─N coupling. Nine C15–N–amino acid‐substituted oroidin derivatives were successfully prepared to demonstrate the applicability and versatility of this oxidative coupling reaction.

Bioinspired Design and Synthesis of Polyphenolic Star‐Like and Hyperbranched Polyester Models

Chemistry – A European Journal, EarlyView.
Gallotannin‐inspired star‐like and hyperbranched aromatic polyesters were synthesized from D‐glucose and ABn‐type phenolic acid monomers, such as protocatechuic acid. This bioinspired approach afforded polyphenolic polymeric nanoparticles able to encapsulate hydrophobic dyes, opening new perspectives for biobased encapsulation and delivery systems ...

Photosensitizing Au(I) Catalysis With Coumarins

Chemistry – A European Journal, EarlyView.
A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐
