Special Issue Information

Dear Colleagues,

We are all familiar with the great problem of rare diseases and of their treatment and cure. “Orphan viruses”, for example, which are not linked to a recognized disease, such as hepatitis G, as well as genes, receptors, and enzymes, lead to orphan diseases, which imply two separate but related concepts: (a) diseases that are neglected by doctors and (b) diseases that affect a small number of people. Thus, the term “orphan drugs” describes rare medicinal products intended for diagnosis, prevention or treatment of life-threatening or very serious rare diseases or disorders. In the last 30 years, efforts have been made to encourage companies to develop orphan drugs.

This Topical Collection, “Orphan Drugs”, of the International Journal of Molecular Sciences will comprise a selection of research papers and reviews offering knowledge on the development of orphan drugs, rare diseases for which research was successful, rare diseases and their treatment with well-known orphan drugs, new entities inserted in clinical applications, and future perspectives.

Moreover, in vitro and in vivo studies will provide a possible high impact in the development of orphan-drug-based strategies and in the identification of the key biological regulation processes that remain uncovered.

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.

Pyrazolines are five-membered heterocycles possessing two adjacent nitrogens. They have attracted significant attention from organic and medicinal chemists due to their potent biological activities and the numerous possibilities for structural diversification. In the last decade, they have been intensively studied as targets for potential anticancer therapeutics, producing a steady yearly rise in the number of published research articles. Many pyrazoline derivatives have shown remarkable cytotoxic activities in the form of heterocyclic or non-heterocyclic based hybrids, such as with coumarins, triazoles, and steroids. The enormous amount of related literature in the last 5 years prompted us to collect all these published data from screening against cancer cell lines, or protein targets like EGFR and structure activity relationship studies. Therefore, in the present review, a comprehensive account of the compounds containing the pyrazoline nucleus will be provided. The chemical groups and the structural modifications responsible for the activity will be highlighted. Moreover, emphasis will be given on recent examples from the literature and on the work of research groups that have played a key role in the development of this field. Full article
