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.

FLP Mediated Conversion of Difluorobenzylalkynes to Fluoroallenyl Oniums via an SN1’ Pathway

Chemistry – A European Journal, EarlyView.
Frustrated Lewis pair (FLP) selective C‒F activation of difluorobenzylalkynes allows the formation of fluoroallenic oniums via an SN1’ substitution pathway. The fluoroallenic onium salts are synthetic precursors that allow subsequent functionalization at allenic and onium positions.

π‐Extended Salphen Scaffolds Enable CO2 Electroreduction and Singlet Oxygen Generation

Chemistry – A European Journal, EarlyView.
New family of π‐extended salen ligands bearing phenylene bridge and tunable phenyl‐based substituents, and their corresponding boron difluoride complexes. Thanks to the extended π‐delocalization over the molecule, the ligands themselves show promising results in electrochemical CO2 reduction to CO, while the complexes act as efficient photosensitizers ...

Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

Chemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Quaternary Pyridinium Salts: A Review

Journal of Oleo Science, 2008
Cationic surfactants are being used in various applications industrially and domestically for a long time. Pyridinium salts come under the category of cationic surfactants. These are unsaturated heterocyclic compounds having different functional groups present either on pyridine ring or at nitrogen atom.

Valorization of oat hulls and spent coffee grounds into pyridinium-modified granular adsorbents for water purification

Sustainability Science and Technology
Agro- and food-waste biomass such as oat hull (Oh) or spent coffee ground (SCG) biomass can yield sustainable adsorbents for water treatment. However, adsorbents in powdered form often face constraints in practical applications (column applications due ...
