Nitrogen-Containing Heterocyclic Compounds in Drug Design: Synthesis, Characterization, and Biological Activity

Dear Colleagues,

Nitrogen-containing heterocyclic compounds occupy a central position in modern medicinal chemistry due to their structural versatility, wide-ranging reactivity, and crucial roles in biological processes. They form the basis of nucleic acids, with purine and pyrimidine rings appearing in essential nitrogenous bases—adenine, guanine, cytosine, thymine, and uracil. Nitrogen heterocycles are also present in many other naturally occurring biomolecules such as vitamins, coenzymes, hormones, several amino acid derivatives, antibiotics, and alkaloids. Moreover, they are key components in a wide variety of drugs. Many antimicrobial agents, antidepressants, antihypertensive, and anticancer drugs contain heterocyclic nitrogen rings. Additionally, nitrogen-containing heterocyclic compounds are used in anti-diabetic, anticonvulsant, anti-inflammatory, and anti-migraine drugs, among many other applications. These structures often improve a drug’s ability to interact with biological targets such as enzymes, receptors, or nucleic acids, increasing their therapeutic efficacy and selectivity. Furthermore, medicinal chemists utilize nitrogen-based heterocycles to optimize pharmacokinetic properties such as solubility and metabolic stability. Their applications in chemistry, pharmacy, and medicine make them indispensable to scientific and technological advancement.

This Special Issue aims to present recent advances in the synthesis, characterization, and biological properties of nitrogen-containing heterocyclic compounds. We welcome submissions of both original research and review articles. Computational studies supporting the development of drug candidates are also encouraged.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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.
