We show that the cooperative reinforcement between hydrogen bonds in guanine quartets is
not caused by resonance‐assisted hydrogen bonding (RAHB). This follows from extensive …

The study aimed to cast light on the structure and internal energetics of guanine-and
xanthine-based model DNA quadruplexes and the physico-chemical nature of the non …

This report is dedicated to development of surface-enhanced Raman spectroscopy (SERS)
based analysis protocol for detection of antibiotics in urine. The key step of the protocol is …

Peptides and nucleic acids can self‐assemble to give supramolecular structures that find
application in different fields, ranging from the delivery of drugs to the obtainment of …

Purines and related compounds are central ingredients in the genetic code and form the
structural framework for many drugs and other bioactive compounds. A key feature of these …

The quartet of xanthine (X), a purine base ubiquitously distributed in most human body
tissues and fluids, has been for the first time fabricated and visualized, as the first alternative …

Structural and energetic features of artificial DNA quadruplexes consisting of base tetrads
and their stacks with Na+/K+ ion (s) inside the central pore and incorporating halogenated …

Abstract RHF and DFT (wB97XD and B3LYP) methods with the 6-31++ G** basis set have
been used to study structural, optoelectronic and thermodynamic properties of Theophylline …

The topology and energetics of guanine (G) quadruplexes is governed by supramolecular
interactions within their strands. In this work, an extensive quantum mechanical (QM) study …

A new class of quadruplex nucleobases, derived from 3‐deazaguanine, has been designed
for various applications as smart quadruplex ligands as well as quadruplex‐based …
