Special Issue Information

Dear Colleagues,

Since recent bioterrorists incidents worldwide, dealing with a wide range of biological toxins is now recognized as vital for an effective response to a bioterrorist attack. Adequate preparedness is of utmost importance in a world increasingly dominated by several bioterrorist threat. Raising awareness of international institutions, national governments and other public and private funding sources to the benefits of countermeasures and the need to stockpile them in advance is also paramount. The immense diversity of microorganisms, animals, insects and plants producing toxins, and toxins subtypes, represent a major challenge. As a consequence, there is a pressing need for the development of potential effective countermeasures against biological weapons. Moreover, botulinum toxin is also available in licensed drugs for the treatment of a variety of medical disorders, in addition to increased use in cosmetic and aesthetic medicine.  A wide range of available in vitro analytical tools are currently employed globally for countermeasures assessments. However there is also a need to reduce animal use globally. The evaluation of currently available in vitro methods for replacement of animal tests able to entirely replace animal model will have a great impact on public health and economy.

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 double-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Toxins 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 2400 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.

Ricin is a toxin found in the castor seeds and listed as a chemical weapon by the Chemical Weapons Convention (CWC) due to its high toxicity combined with the easiness of obtention and lack of available antidotes. The relatively frequent episodes of usage or attempting to use ricin in terrorist attacks reinforce the urge to develop an antidote for this toxin. In this sense, we selected in this work the current RTA (ricin catalytic subunit) inhibitor with the best experimental performance, as a reference molecule for virtual screening in the PubChem database. The selected molecules were then evaluated through docking studies, followed by drug-likeness investigation, molecular dynamics simulations and Molecular Mechanics Poisson–Boltzmann Surface Area (MM-PBSA) calculations. In every step, the selection of molecules was mainly based on their ability to occupy both the active and secondary sites of RTA, which are located right next to each other, but are not simultaneously occupied by the current RTA inhibitors. Results show that the three PubChem compounds 18309602, 18498053, and 136023163 presented better overall results than the reference molecule itself, showing up as new hits for the RTA inhibition, and encouraging further experimental evaluation.
