Special Issue Information

Dear Colleagues,

Therapeutic peptides development has come a long way since the discovery of insulin, and a vast number of peptides for treating many diseases have arrived at the clinic over the last 40 years. From complete natural amino acid sequences to non-natural amino acids, conjugations to lipids and proteins, pegylation, the creation of peptoids and macrocycles, polymerization to protein-like particles, and so forth, the ADME fate of these peptides has dramatically changed. More than 170 peptides are now in active clinical development and many more in preclinical studies. Despite this apparent revolution, there is no clear DMPK guidance for characterizing these peptides. Extracellular targets and elimination by proteolysis and renal filtration are not standard features of the new therapeutic peptides; hence a customized set of assays is needed to guide their development.

This special issue aims to provide examples of how these novel entities' absorption, distribution, metabolism, and excretion are studied from early discovery to human testing.

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.

Thyrotropin-releasing hormone (TRH) is a tripeptide that regulates the neuroendocrine thyroid axis. Moreover, its widespread brain distribution has indicated that it is a relevant neuromodulator of behaviors such as feeding, arousal, anxiety, and locomotion. Importantly, it is also a neurotrophic peptide, and thus may halt the development of neurodegenerative diseases and improve mood-related disorders. Its neuroprotective actions on those pathologies and behaviors have been limited due to its poor intestinal and blood–brain barrier permeability, and because it is rapidly degraded by a serum enzyme. As new strategies such as TRH intranasal delivery emerge, a renewed interest in the peptide has arisen. TRH analogs have proven to be safe in animals and humans, while not inducing alterations in thyroid hormones’ levels. In this review, we integrate research from different approaches, aiming to demonstrate the therapeutic effects of TRH, and to summarize new efforts to prolong and facilitate the peptide’s actions to improve symptoms and the progression of several pathologies.
