For the last few decades, viral infectious diseases have continued to be a major health concern worldwide, causing relevant epidemiological, financial, and logistical implications. The use of many conventional drugs is hampered by a lack of efficacy, emergence of resistance, adverse effects, and high costs. Thus, new strategies and therapeutic alternatives are constantly needed. Nucleosides are fundamental building blocks of biological systems that show a wide range of biological activities. Consequently, extensive modifications have been made to both the heterocyclic base and the sugar moiety in order to avoid the drawbacks shown by nucleosides or analogues in certain applications, mainly due to enzymatic degradations. The design and synthesis of molecules for the fight against aggressive and potentially fatal diseases, also including cancer and bacterial infections, remain important challenges. Chemical literature in this field is constantly growing and reports extremely valuable synthetic strategies that apply old and new chemical reactions to prepare a wide variety of nucleosides and analogs in high yields in few synthetic steps and with remarkably lower costs.
This Special Issue aims to attract contributions on all the aspects concerning the synthesis, through various and different strategies, of classical nucleosides, carbocyclic nucleoside, and analogs. These results can be considered fully consistent if in vitro biological evaluations of the synthetized compounds are also reported. This will be the challenge to further exploring the range of biological effects and potential applications as antivirals of brand-new compounds.

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 papers will be 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 2000 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.
