Special Issue Information

Dear Colleagues,

Melatonin (N-acetyl-5-methoxytryptamine) is a hormone synthesized and secreted mainly by the pineal gland in the dark. In the last 20 years, multiple reports (clinical trials and in vivo and in vitro studies) have documented that the pineal hormone has many potential benefits when it is included in protocols designed to treat tumors because it modulates tumor gene expression impairing cell growth and inhibiting angiogenesis and metastasis. As melatonin has no toxicity, it deserves to be considered as an agent for use as a co-adjuvant in cancer prevention and treatment. This Special Issue aims to bring together current knowledge about melatonin targeting, delivery, and dosage form design (as controlled-release systems), and the newest findings concerning melatonin pharmacokinetics (absorption, distribution, metabolism, and excretion) and pharmacodynamics (interactions between melatonin and its different receptors, such as MT-1, MT-2, calmodulin, or nuclear receptors).

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. Pharmaceutics 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.

Doxorubicin is a potent chemotherapeutic drug; however, its clinical application has been limited due to its cardiotoxicity. One of the major mechanisms of doxorubicin-induced cardiotoxicity is the induction of oxidative stress. Evidence from in vitro and in vivo studies demonstrates that melatonin attenuated the increase in ROS production and lipid peroxidation from doxorubicin. Melatonin has been shown to exert protective effects on mitochondria damaged by doxorubicin via attenuating the depolarization of the mitochondrial membrane, restoring ATP production, and maintaining mitochondrial biogenesis. Doxorubicin increased mitochondrial fragmentation which impaired mitochondrial function; however, these adverse effects were reversed by melatonin. Melatonin also modulated cell death pathways by suppressing apoptotic and ferroptotic cell death caused by doxorubicin. These beneficial effects of melatonin could be responsible for the attenuation of changes in ECG, left ventricular dysfunction, and hemodynamic deterioration caused by doxorubicin. Despite these potential benefits, clinical evidence regarding the impact of melatonin in reducing cardiotoxicity induced by doxorubicin is still limited. Further clinical studies are justified to evaluate the efficacy of melatonin in protecting against doxorubicin-induced cardiotoxicity. This valuable information can be used to warrant the use of melatonin in a clinical setting under this condition. Full article

The purpose of this systematic review is to provide an overview of the existing knowledge on the therapeutic potential of melatonin to counteract the undesirable effects of chemotherapy in breast cancer patients. To this aim, we summarized and critically reviewed preclinical- and clinical-related evidence according to the PRISMA guidelines. Additionally, we developed an extrapolation of melatonin doses in animal studies to the human equivalent doses (HEDs) for randomized clinical trials (RCTs) with breast cancer patients. For the revision, 341 primary records were screened, which were reduced to 8 selected RCTs that met the inclusion criteria. We assembled the evidence drawn from these studies by analyzing the remaining gaps and treatment efficacy and suggested future translational research and clinical trials. Overall, the selected RCTs allow us to conclude that melatonin combined with standard chemotherapy lines would derive, at least, a better quality of life for breast cancer patients. Moreover, regular doses of 20 mg/day seemed to increase partial response and 1-year survival rates. Accordingly, this systematic review leads us to draw attention to the need for more RCTs to provide a comprehensive view of the promising actions of melatonin in breast cancer and, given the safety profile of this molecule, adequate translational doses should be established in further RCTs.
