Special Issue Information

Dear Colleagues,

Infectious diseases are still responsible for a very high number of deaths worldwide, and mainly affect low- and moderate-income countries according to the WHO. These diseases are mainly communicable, although there are some non-communicable infectious diseases, such as parasitic diseases in which the life cycle of the parasite does not rely on inter-individual direct transmission. They are caused by pathogenic bacteria, viruses, parasites or fungi.

While significant progress has been made in recent years in treating these, notably in preventing sleeping sickness with the introduction of fexinidazole, many efforts remain to be made. This is especially true in areas like tuberculosis or fungal infections.

The COVID-19 crisis has brutally revived the awareness of the loss of control that humanity could suffer in failing to contain the spread of infectious diseases. It also highlighted the problem of virus mutation. More broadly, whatever the pathogens involved, the pathogenic resistance poses a real threat to patient care, and it is increasingly urgent to identify and develop anti-infective agents with new mechanisms of action. 

Hit-to-lead (H2L), also known as lead generation, is a powerful strategy used in early drug discovery. In this method, small molecule hits from high-throughput screening (HTS) are evaluated and optimized to identify promising lead compounds.  

The aim of this Special Issue is to summarize the state of the art and the latest findings in the field of the hit-to-lead design of new anti-infective drugs, as well as to elucidate future directions.

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. Pharmaceuticals 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 2900 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.

The continuing need for the discovery of potent antibacterial agents against antibiotic-resistant pathogens is the driving force for many researchers to design and develop such agents. Herein, we report the design, synthesis, and biological evaluation of amidine derivatives as new antibacterial agents. Compound 13d was the most active in this study against a wide range of antibiotic-resistant, and susceptible, Gram-positive, and Gram-negative bacterial strains. Time–kill assay experiments indicated that compound 13d was an effective bactericidal compound against the tested organisms at the log-phase of bacterial growth. Docking simulations were performed to assess in silico its mode of action regarding UPPS, KARI, and DNA as potential bacterial targets. Results unveiled the importance of structural features of compound 13d in its biological activity including central thiophene ring equipped with left and right pyrrolo[2,3-b]pyridine and phenyl moieties and two terminal amidines cyclized into 4,5-dihydro-1H-imidazol-2-yl functionalities. Collectively, compound 13d represents a possible hit for future development of potent antibacterial agents. Full article
