Special Issue Information
Dear Colleagues,
In recent decades, X-Ray crystallography has been affirmed as a powerful technique to provide atomic-level details on protein targets and their interactions with specific drugs. Structural information, derived from X-ray crystallographic data, plays a key role in the rational development of improved affinity drugs, showing the compound binding modes in specific sites of target proteins. Structural information is also pivotal to elucidate peculiar mechanisms of inhibition, such as for the b-lactamase inhibitor avibactam, whose mechanism of recyclization upon deacylation from the target enzyme was unveiled by protein crystallography.
Recently, highly automated programs based on X-ray crystallography have been created to potentiate fragment-based screening, a well-established and powerful approach to early drug discovery. The most advanced synchrotron X-ray sources are, or will soon be, equipped with dedicated high throughput chemical fragment screening beamlines. Through these automated methods, also covering data collection and analysis, large libraries of fragments can be investigated, allowing 1000 or more compounds to be screened individually in less than a week.
This Special Issue features multidisciplinary research articles and reviews focused on the contribution of protein crystallography in drug discovery and development. The main topics covered by this Special Issue are the structural investigation of drug targets by X-ray crystallography and the application of this technique to structure-based and fragment-based drug development and to the elucidation of peculiar mechanisms of inhibition.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
