Special Issue Information

Dear Colleagues,

We are pleased to inform you of the launch of a Special Issue on “Virus Entry Inhibitors” in IJMS. Virus entry into host cells is the first step of all enveloped and non-enveloped viruses. Virus entry inhibitors are a class of antiviral drugs that prevent the entry or fusion of a virus into a host cell. These inhibitors target specific mechanisms or proteins involved in the virus entry process, thereby blocking the virus from infecting the host cell.

Considerable progress has been made in this area of research, especially since the FDA approved the first HIV-1 fusion inhibitor, enfuvirtide (brand name Fuzeon), and CCR5 antagonist maraviroc (brand name Selzentry).

With this Special Issue, we will aim to provide an overview of the latest progress in the development of entry inhibitors that include small molecules, peptidomimetics, and that are peptide-based or antibody-based (such as broadly neutralizing antibody (bNAb), etc. We also want to encourage the submission of novel findings on virus entry mechanisms, preclinical and clinical assessments of virus entry inhibitors, and the future trends in developing these inhibitors.

We encourage the submission of original research articles, brief communications, reviews, and commentaries. We look forward to receiving your contributions.

Dr. Asim Debnath
Guest Editor

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.

Trypsin-like serine proteases are involved in many important physiological processes like blood coagulation and remodeling of the extracellular matrix. On the other hand, they are also associated with pathological conditions. The urokinase-pwlasminogen activator (uPA), which is involved in tissue remodeling, can increase the metastatic behavior of various cancer types when overexpressed and dysregulated. Another member of this protease class that received attention during the SARS-CoV 2 pandemic is TMPRSS2. It is a transmembrane serine protease, which enables cell entry of the coronavirus by processing its spike protein. A variety of different inhibitors have been published against both proteases. However, the selectivity over other trypsin-like serine proteases remains a major challenge. In the current study, we replaced the arginine moiety at the P1 site of peptidomimetic inhibitors with different bioisosteres. Enzyme inhibition studies revealed that the phenylguanidine moiety in the P1 site led to strong affinity for TMPRSS2, whereas the cyclohexylguanidine derivate potently inhibited uPA. Both inhibitors exhibited high selectivity over other structurally similar and physiologically important proteases. Full article
