There will be regular postings by members of my research group and frequent compilations of recent articles in the field. Check it out.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7858146396908506163-6790973317147987194?l=g-quadruplex.blogspot.com' alt='' /></div>Jose M.

Anyone interested in getting a broad overview of almost everything related to G-quadruplexes will find this book useful. It covers everything from structure, energetics, dynamics and biological function to ligand-recognition and supramolecular/nanotech aplications.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7858146396908506163-6022377298996387738?l=g-quadruplex.blogspot.com' alt='' /></div>Jose M.

In a nutshell, G-quadruplexes are supramolecular structures formed by the self-assembly of guanine bases. More specifically it consists of planar tetramers of guanine known as tetrads, which in turn stack (usually aided by cation binding) to form higher order structures (view a picture in the previous post). G-quadruplexes are formed by individual guanines (base, nucleoside, nucleotide) or by oligomeric guanines (G-rich oligonucleotides of DNA, RNA or even non-natural PNA). Research in the field of G-quadruplex in the last 10 years has increased dramatically due to its potential implications in diseases such as cancer as well as their use in nanotechnology applications.<br /><br />My research laboratory at the University of Puerto Rico, Río Piedras campus deals primarily with the synthesis of guanine derivatives and studies of its supramolecular properties. We are currently using such guanine derivatives as scaffolds to construct nanostructures and also to bind to Quadruplex-DNA (QDNA) for medicinal chemistry purposes.<br /><br />To be continued...<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/7858146396908506163-1392599643916911003?l=g-quadruplex.blogspot.com' alt='' /></div>Jose M.
