Mechanochemical Strategies Applied to the Late‐Stage Modifications of Pharmaceutically Active Compounds

open access: yesAngewandte Chemie International Edition, EarlyView.
This review highlights mechanochemical strategies for the late‐stage modification of active pharmaceutical ingredients (APIs), providing a valuable resource for selecting substrates to evaluate the pharmaceutical potential of novel and existing (mechano)chemical protocols.

Second generation silver(I)-mediated imidazole base pairs

open access: yesBeilstein Journal of Organic Chemistry, 2014
The imidazole–Ag(I)–imidazole base pair is one of the best-investigated artificial metal-mediated base pairs. We show here that its stability can be further improved by formally replacing the imidazole moiety by a 2-methylimidazole or 4-methylimidazole ...

Influence of a fluorobenzene nucleobase analogue on the conformational flexibility of RNA studied by molecular dynamics simulations [PDF]

open access: yes, 2006
Chemically modified bases are frequently used to stabilize nucleic acids, to study the driving forces for nucleic acid structure formation and to tune DNA and RNA hybridization conditions.

Inter‐Nanoparticle FRET for Biosensing: Photophysics Versus Size

open access: yesAngewandte Chemie International Edition, EarlyView.
Förster resonance energy transfer (FRET) systems with luminescent nanoparticles (NPs) as donors and acceptors (inter‐NP FRET) combine unique photophysical properties with large sizes. This review discusses the influence of NP type, architecture, surface chemistry, and optical properties on FRET and the pros and cons of inter‐NP FRET for bioanalytical ...

The Origin of the Feedstock Molecules for Life on the Hadean Earth

open access: yesAngewandte Chemie International Edition, EarlyView.
The origin of life in the Hadean eon required the formation of amino acids and nucleosides among the key molecules of life. In an often postulated strongly reducing atmosphere, HCN and its derivatives are robustly formed as plausible starting molecules. But HCN does not form in a Hadean, weakly reducing atmosphere.
