Most of the organic compounds used as therapeutics, as well as intermediates utilized for their synthesis, contain heterocyclic motifs. A heterocycle is a ring with at least one atom that is not carbon. Nitrogen, oxygen, and sulfur are the primary elements seen in common heterocycles and play a critical role in drug discovery. In detail, nitrogen heterocycles contain at least one nitrogen atom in the ring. Based on the size of the ring, there are three, four, five, six, seven and eight-membered rings, as well as fused, bicyclic and macrocyclic heterocycles of nitrogen. Furthermore, these may be described as aromatic, saturated or unsaturated. Depending on the structure and on the type of bonds, such compounds show different acid–base properties and can contain one, two or more nitrogen atoms. Nitrogen-containing scaffolds are among the most significant structural components of therapeutic agents. Furthermore, there are a plethora of natural products which are nitrogen-containing heterocyclic that serve as the basis for many different substances, including alkaloids, vitamins, hormones, dyes, antibiotics, herbicides, or nutraceuticals. Over the past decades, much attention has been devoted to the development of and pharmacological studies into heteroaromatic organic compounds (such as benzimidazoles, benzothiazoles, indole, oxadiazole, imidazole, isoxazole, pyrazole, triazoles, quinolines and quinazolines) that are currently considered privileged scaffolds for different therapeutic agents. Indeed, they show a wide range of biological activities, representing nearly 60% of all FDA-approved drugs, with more than 880 nitrogen-based heterocyclic drugs approved by the US FDA. For instance, nitrogen-based heterocyclic compounds are widely reported in the literature as anticancer agents and represented 73% of the approved anticancer drugs in 2015. This Special Issue will publish research papers with topics including, but not limited to, the preparation of aromatic and non-aromatic nitrogen-containing heterocycles endowed with any biological action. We also welcome contributions that highlight the importance of the nitrogen-based scaffolds that are widely found in agrochemicals, dyes, cosmetics and functional materials. The aim of the present Special Issue is primarily to present an overview primarily of the state of the art of synthetic methods and recent advances in the synthesis of nitrogen-based heterocycles.

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. Pharmaceuticals is an international peer-reviewed open access monthly 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 2900 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.
