Respiratory infections caused by viruses such as influenza and coronavirus are a serious global problem due to their high infection rates and potential to spark pandemics, such as the current COVID-19 pandemic. Although preventing these infections by using vaccines has been the most successful strategy to date, effective vaccines are not always available. Therefore, developing broad-spectrum anti-viral drugs to treat s Read More

COVID-19, an infectious disease caused by a newly discovered enveloped virus (SARS-CoV-2), was first reported in Wuhan, China, in December 2019 and affected the whole world. The infected individual may develop symptoms such as high fever, cough, myalgia, lymphopenia, respiratory distress syndrome etc., or remain completely asymptomatic after the incubation period of two to fourteen days. As the virus is transmitt Read More

Coronaviruses (CoVs) belong to a large family of zoonotic supercapsid viruses, including about 40 species of RNA-containing viruses with several strains capable of causing damage to the lungs and respiratory tract. The severe acute respiratory syndrome coronavirus (SARS-CoV) was responsible for the worldwide SARS outbreak in 2003. The rapid global spread of SARS-CoV-2 has been the cause of significant health co Read More

Coronaviruses (CoVs) are enveloped viruses with particle-like characteristics and a diameter of 60-140 nm, positively charged, and single-stranded RNA genomes, which caused a major outbreak of human fatal pneumonia in the beginning of the 21st century. COVID-19 is currently considered a continuous potential pandemic threat across the globe. Therefore, considerable efforts have been made to develop innovative methods Read More

A newly identified virus appeared in Wuhan, China, in December 2019, was named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and caused the coronavirus disease 2019 (COVID-19). SARS-CoV-2 presents similarities with two previous coronavirus pandemics, MERS (Middle East Respiratory Syndrome) and SARSCoV, concerning phylogenetic origin, structural composition, and clinical symptoms, thus, leading t Read More

Photodynamic therapy has emerged as an effective therapeutic alternative to treat oncological, cardiovascular, dermatological, infectious, and ophthalmic diseases. Photodynamic therapy combines the action of a photosensitizer with light in the presence of oxygen to generate reactive oxygen species, capable of reacting with cellular components, resulting in injury and, consequently, inducing cellular death. Phthalocyani Read More

Diabetes strongly influences the patient’s quality of life. The incidence of type 2 diabetes (T2D) accounts for approximately 90% of diabetic patients. Natural polysaccharides have been widely used for diabetes management. Changes in gut microbiota can also be used for the prevention and treatment of diabetes. In this review, the effects of different natural polysaccharides on gut microbiota, as well as the relationship b Read More

Pathogenic Escherichia coli poses a serious threat to global public health and is especially dangerous with the increase of antibiotic resistance. β-Glucuronidase (GUS) and some other glycosidases can serve as useful biomarkers or indicators for the detection of E. coli. The probes made up of a glycosyl residue (recognition group), a label or reporter group, and a linkage that is generally a direct glycosidic bond, are powerful an Read More

Pancreatic Ductal Adenocarcinoma (PDA) is a highly metastatic tumor, and the liver is its first target, which restricts the use of medications. PDA is considered one of the most aggressive types of cancer in the world, with an extremely short survival time, depending on the stage of diagnosis. In non-surgical cases, chemotherapy alternatives are only effective in 40% to 60% of patients. The low efficiency of treatments occurs mai Read More

Background: A growing body of evidence suggests that Hsp70, which is overexpressed in human breast tumors, plays a role in tumorigenesis and tumor progression in breast cancer as well as in its aggressive phenotypes. Hsp70 constitutes a potential therapeutic target in the treatment of this disease. Methods: We developed a new series of rhodacyanine-based Hsp70 inhibitors, represented by compounds 1 and 6, in which the Read More
