Bacterial adhesion and subsequent biofilm formation on material surfaces represent a serious problem in society from both an economical and health perspective. Surface coating approaches to prevent bacterial adhesion and biofilm formation are of increased importance due to the increasing prevalence of antibiotic resistant bacterial strains. Effective antimicrobial surface coatings can be based on an anti-adhesive Read More

The possibility to develop new antibacterial agents raised much interest recently. The main classes of antibiotics clinically used nowadays act towards the inhibition of four classical targets: a) cell wall biosynthesis; b) protein biosynthesis; c) DNA and RNA biosynthesis; d) folate biosynthesis. Recently, carbonic anhydrases (CAs, EC 4.2.1.1) started to be investigated in detail in pathogenic bacteria, in the search for antibiotics w Read More

With the alarming resistance to currently used antibiotics, there is a serious worldwide threat to public health. Therefore, there is an urgent need to search for new antibiotics or new cellular targets which are essential for survival of the pathogens. However, during the past 50 years, only two new classes of antibiotics (oxazolidinone and lipopeptides) have reached the clinic. This suggests that the success rate in discovering ne Read More

Although photodynamic therapy (PDT) was discovered over a hundred years ago by its ability to destroy microorganisms, it has been developed mainly as a cancer therapy. In recent years, due to the inexorable rise in multi-antibiotic resistant strains of pathogens, PDT is being considered as a versatile antimicrobial approach to which microbial cells will not be able to develop resistance. The goal of this review is to survey the Read More

Sterols play an essential role in the physiology of eukaryotic cells; they play a pivotal role in the normal structure and function of cell membranes and also act as precursors for the synthesis of several different molecules like steroid hormones. Trypanosomatids and fungi have an essential requirement of ergosterol and other 24-alkyl sterols, which are absent in mammalian cells, for their survival and growth. At least 20 met Read More

Tuberculosis (TB) which is caused by the resilient pathogen Mycobacterium tuberculosis (MTB) has re-emerged to become a leading public health problem in the world. The growing number of multi-drug resistant MTB strains and the more recently emerging problem with the extensively drug resistant strains of the pathogen are greatly undermining conventional anti-TB therapeutic strategies which are lengthy and expose pati Read More

Chagas’ disease is one of the most impactful and prevalent neglected tropical diseases in the Americas, specially affecting the poor and underdeveloped areas in Latin America. Aggravating this scenario, the medicines used in the current chemotherapy are old, toxic and present a low efficacy to treat the chronic stage of this disease. In addition, resistant strains of Trypanosoma cruzi, the etiological agent, are frequ Read More
