Special Issue Information

Dear Colleagues,

Drug-induced neurotoxicity and neurodegeneration are emerging as important triggers of human diseases, significantly impacting individual health and public healthcare systems worldwide. In contemporary society, the rapid development of drugs and the increasing exposure to diverse pharmaceutical agents, abused substances, and environmental toxins make a deeper understanding of the mechanisms underlying neurotoxic damage essential to develop effective mitigation strategies.

In this Special Issue, we are particularly interested in contributions on the mechanisms of drug-induced neurotoxicity and neurodegeneration at molecular, cellular and organismal levels, innovative in vitro, in vivo, and in silico models that depicts the dynamics of neuronal damage, biomarkers and altered pathways useful for early diagnosis, translational studies linking experimental findings to clinical outcomes, and putative therapeutic strategies to prevent or mitigate neurotoxic insults. Thus, this Special Issue aims to bridge the gap between experimental research and clinical practice by broadly exploring how toxic exposures affect the nervous system.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Designer drugs like 2C-I and 25I-NBOMe have emerged as potent psychoactive substances, with several reports linking their consumption to severe poisoning and fatalities. However, there is limited information on their toxicity, particularly in in vivo models. In this manuscript, we evaluate the survival, developmental, and reproductive impact of these designer drugs on the model organism Caenorhabditis elegans (C. elegans). For this purpose, adult worms synchronized at the L1 stage were exposed to growing concentrations of 2C-I and 25I-NBOMe. The animal survival rate and the putative effects of the drugs on C. elegans development and reproductive behavior were assessed after 24 h of exposure. A concentration-dependent decrease in animal survival was observed. 25I-NBOMe was approximately six times more toxic than 2C-I (LC50 values—1.368 mM for 2C-I and 0.236 mM for 25I-NBOMe). Furthermore, sublethal concentrations of both drugs delayed animal development and reduced the total progeny but not its survival. Overall, these findings underscore the developmental and reproductive risks associated with exposure to 2C-I and 25I-NBOMe, even at sublethal concentrations. Full article
