Special Issue Information

Dear Colleagues,

Density functional theory (DFT), as recognized by the Nobel Prize in Chemistry in 1998, is approaching new horizons of multi-, trans-, and nano-chemistry. Since its inception and follow-up innovative developments, it has succeeded in describing, in the otherwise truly complex/complicated realm of many electrons evolving in many charge potential fields, almost the entire chemistry of single and pair electronic interactions through appropriate rearrangements of potential/forces in many-electronic samples in order to properly represent the entire system’s structure and reactivity. However, beyond the (perhaps unique) way of representing N-interactions via 1- and 2- electronic interactions (+ the required corrections of representation, namely Exchange, correlation, gradient/perturbative terms, multiple-configurations, etc.), it  recognized, relatively recently, that such an approach opens the door to chemical-based artificial intelligence by employing mono- and paired- bits/qubits of information in a complex information sample. Therefore, DFT is at the edge of reinventing itself, either in fundamental or applicative aspects: from the asymmetric Hubbard dimer to the self-assembly of carbon-based supramolecular complexes; from the description of dynamic chemical bonding/covalent bonding to deep learning (molecular) machines/algorithms; from mean-field density matrix decompositions to the time-dependent description of two-dimensional semiconductors; and from conceptual DFT explaining chemical reactivity to drug-likeness, bioactive scores and anticancer peptides, among others. All of these developments open new horizons for DFT as a theory, a versatile computational framework, and an adaptive paradigm for a plethora of phenomena in which the molecule unites with cells’ constituents and ultimately with intelligence (as an autonomous network entity of dynamical information); i.e., the molecular artificial in Cerebro and in silico models, simulations and intelligence to be next synthesized according to in vitro and in vivo protocols in 2021. I thus kindly invite you to contribute a visionary project from your particular viewpoint that is projected, sustained or aided by DFT.

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.

Cancer is a disease that occurs as a result of abnormal or uncontrolled growth of cells due to DNA damage, among many other causes. Certain cancer treatments aim to increase the excess of DNA breaks to such an extent that they cannot escape from the general mechanism of cell checkpoints, leading to the apoptosis of mutant cells. In this study, one of the Sarco-endoplasmic reticulum Ca2+ATPase (SERCA2a) inhibitors, Istaroxime, was investigated. There has been very limited number of articles so far reporting Istaroxime’s anticancer activity; thus, we aimed to evaluate the anticancer effects of Istaroxime by cell proliferation assay and revealed the cytotoxic activity of the compound. We further determined the interaction of Istaroxime with topoisomerase enzymes through enzyme activity tests and detailed molecular modeling analysis. Istaroxime exhibited an antiproliferative effect on A549, MCF7, and PC3 cell lines and inhibited Topoisomerase I, suggesting that Istaroxime can act as a Topoisomerase I inhibitor under in vitro conditions. Molecular docking analysis supported the experimental observations. A chemical reactivity analysis of the Istaroxime molecule was made in the light of Density Functional Theory computations. For this aim, important chemical reactivity descriptors such as hardness, electronegativity, and electrophilicity were computed and discussed as detailed. Full article
