Special Issue Information
Dear Colleagues,
Bioactive ligands are compounds with notable selectivity and reactivity toward free radicals, cancer cell lines, bacteria, viruses, fungi, and more. These ligands interact with biomolecular targets through various mechanisms, enabling potential therapeutic applications. Their structural adaptability and ability to form stable complexes make them promising candidates for pharmaceutical development. Organometallic compounds, incorporating ions such as Cu, Fe, Zn, Pd, Sn, Ni, and Ru, along with bioactive ligands, exhibit significant biological activities, including antibacterial, anti-inflammatory, antioxidant, and cytotoxic effects.
Computational chemistry—primarily the Density Functional Theory (DFT)—is an indispensable tool for predicting stability, mapping synthetic reaction pathways, assigning spectra, and examining both inter- and intramolecular interactions. Additionally, molecular docking and molecular dynamics are crucial for investigating the interactions of these compounds with key biomolecules, including proteins, lipids, and DNA. Given the established data on biological activity, toxicity, and physicochemical properties, Quantitative Structure–Activity Relationship (QSAR) studies can be applied to predict the properties of theoretically designed or synthesized compounds.
This Special Issue aims to highlight and showcase contemporary synthetic methods for the chemical modification of bioactive compounds, detailing the modification mechanisms and providing complete chemical characterization of intermediates and products. The research topic also includes theoretical methods for predicting reaction mechanisms, compound stability, complexation modes, and interactions using DFT, the Natural Bond Orbital, and the Quantum Theory of Atoms in Molecules analyses. Articles involving molecular docking, molecular dynamics, and QSAR studies are also welcome if they address predictions of physicochemical properties, binding modes, toxicity, or biological activity of different compounds and their transition metal complexes.

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. Crystals 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 2100 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.
