Special Issue Information
Dear Colleagues,
Calcium signaling is one of the most important ways of cell communication. It controls a plethora of physiological processes and, therefore, needs to be finely regulated. The alteration of such balance is the chief cause of many diseases. For instance, the only common event observed in the various neurodegenerative diseases is indeed Ca2+ overload.
Thus, the “Ca2+-antagonists” is one of the classical drug families, which is prescribed for cardiovascular diseases. They reduce the uptake of Ca2+ through the voltage-gated Ca2+ channels (VGCC), for instance in smooth muscle cells to dissipate hypertension. But despite this essential therapeutic role, cell Ca2+ modulators are not usually seen as alternative drugs beyond the cardiovascular system. This is due to the belief that they possess severe adverse effects, such as lowering blood pressure in a patient, which is not a desirable effect unless she/he was hypertensive. By contrast, in the latest decade, a deep knowledge of all types of VGCC and their pharmacological differences, both in the subtype and in the localization, has been documented. This has opened the opportunity to face several neurodegenerative diseases such as Parkinson’s, where a specific VGCC subtype is affected.
On the other hand, cell Ca2+ levels are a consequence of the modulated activity of several other Ca2+-transporters located not only in the plasma membrane but also in intracellular organelles. These new actors modify the amplitude and the subcellular localization of the Ca2+ signal, allowing the generation of “hot spots” in certain subcellular places while avoiding a whole-cell Ca2+ overload. To achieve these actions, new drug targets like the Na+/Ca2+ exchangers (plasmallemal and mitochondrial), the mitochondrial Ca2+ uniporter or the newly discovered Ca2+ homeostasis modulator 1 channel, can be studied for the discovery of new cell Ca2+ modulators. As a consequence, in recent years, medicinal chemists have reported drugs modulating other Ca2+ channels, exchangers, or transporters for the treatment of pathologies beyond the cardiovascular ones.
This Special Issue of Molecules titled “Drugs Modulating Ca2+ Signaling” is devoted to several research topics related to the search for new chemical entities able to modify the cell Ca2+ signal. Topics of interest include (i) computational design, (ii) synthesis, (iii) natural products, (iv) pharmacological screening, (v) structure-activity relationships, (vi) electrophysiology with new Ca2+ modulators, (vii) chemical biology, and in general other topics related to the search for new cell Ca2+ modulators.

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. 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.
