Chemistry – A European Journal, EarlyView.5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

Chemistry – A European Journal, EarlyView.ABSTRACT Fluorouracil‐platinum(IV) prodrugs represent a novel class of multimechanistic chemotherapeutics with enhanced anticancer potential. The prodrugs PtIVP‐5FUMeOBut and PtIV56‐5FUMeOBut were actualized by derivatising the clinical drug 5‐fluorouracil (5FU) and coordinating it to platinum(IV) complexes, leveraging the established cytotoxicity of ...

The Asymmetric Self‐Replicative Alkylation of N‐Arylaldimines Using Organolithium Reagents
Chemistry – A European Journal, EarlyView.Here, we report a new asymmetric autoinductive reaction; the addition of nBuLi to N‐arylaldimines to form chiral lithium amides. The reaction proceeds with full conversion and complete transfer of chirality, representing the first example of an asymmetric autoinductive reaction with organolithium reagents.

A laboratory infrared model of astrophysical pyrimidines [PDF]
Nucleobases are essential molecules for life, forming integral parts of DNA and RNA in all terrestrial life forms. Despite evidence of their abiotic synthesis in meteorites and laboratory simulations of interstellar medium (ISM) conditions, nucleobases ...
