Engineering Lipid Nanoparticles for Precision RNA Delivery: Design Principles, Targeting Strategies, and Clinical Prospects

open access: yesCancer Nexus, EarlyView.
ABSTRACT Lipid nanoparticles (LNPs) represent the most clinically advanced platform for RNA delivery and have enabled major breakthroughs in vaccines and gene therapies. However, their broader application is still limited by inefficient extrahepatic delivery, immunogenicity, and insufficient control over tissue‐ and cell‐specific targeting. This review

Cyanoacetamidobetaine—A Zwitterionic Nitrile Derivative

open access: yesChemistryOpen, EarlyView.
The reaction of sodium dicyanamide with betainium chloride in aqueous solution affords N‐cyano‐2‐(trimethylammonio)acetaminide (cyanoacetamidobetaine). Single crystal X‐ray diffraction reveals a monoclinic structure comprising a trimethylammonium head group connected to a cyanoacetaminide unit via a methylene bridge.

Peptidic product derived from trypsin autolysis modulates insect digestive proteases and supports plant biochemical defense

open access: yesPest Management Science, EarlyView.
XXXX Abstract BACKGROUND Spodoptera frugiperda, commonly known as the fall armyworm, is a highly economically significant pest that affects various crops, resulting in substantial losses in productivity. Managing this pest primarily relies on chemical insecticides; however, the repeated development of resistance to these chemicals has rendered them ...

Pyridines and Quinolines from 1,3-Dichloro-Trimethinecyanines Pyrimidine and Quinazoline from Azacyanine

open access: yesCHIMIA, 1976
A new synthesis of 2,4-bis(dialkylamino)-pyridines and quinolines is reported. Starting from primary aryl amines or aliphatic imines a mechanism via ynamine-amidines is followed if the cyanine Ia is used as reagent. When the cyanine is substituted, (I.R.

Targeting Expanded CUG and CTG Repeats as a Therapeutic Approach for Myotonic Dystrophy Type 1 (DM1)

open access: yesChemMedChem, Volume 21, Issue 5, 13 March 2026.
DM1 is an RNA gain‐of‐function disease caused by CTG repeat expansion, producing toxic r(CUG)exp RNA that sequesters MBNL1 and impairs splicing. This review covers the field of CUG and CTG ligands identified or rationally designed as DM1 drug candidates, highlighting their molecular design, RNA‐ or DNA‐binding modes, in vitro affinities and ...
