Up to present, many deadly diseases are caused by viral infections. Herbal therapy is a preventive effort made by the community to overcome diseases that come from viruses. Antiviral drug resistance is also the reason people consume herbs from natural ingredients. One of the natural products has the potential to come from kelulut bee products consisting of propolis, pollen, and honey. The kelulut bee or stingless bee is a type of bee that is commonly found in countries with tropical climates such as Indonesia, but there is still little scientific information that examines its potential as an antiviral. This study aims to analyze data on the potential antiviral activity of kelulut bee products through the collection of related articles. The research conducted is a literature review, so the research method is carried out by collecting related articles using search engines such as NCBI, Sciencedirect, and Google Schoolar. Kelulut bee products such as propolis, pollen and honey have potential pharmacological activity as antiviral. This anti-viral activity is due to the presence of compounds such as alkaloids, flavones, apigenin derivatives and other compounds which will be discussed further. Natural products from kelulut bees have potential as an alternative to antiviral therapy. It is also recommended to conduct more in-depth research on the potential of kelulut bee natural products to obtain these therapeutic products.

Viral infections are among the most complex medical problems and have been a major threat to the economy and global health. Several epidemics and pandemics have occurred due to viruses, which has led to a significant increase in mortality and morbidity rates. Natural products have always been an inspiration and source for new drug development because of their various uses. Among all-natural sources, plant sources are the most dominant for the discovery of new therapeutic agents due to their chemical and structural diversity. Despite the traditional use and potential source for drug development, natural products have gained little attention from large pharmaceutical industries. Several plant extracts and isolated compounds have been extensively studied and explored for antiviral properties against different strains of viruses. In this review, we have compiled antiviral plant extracts and natural products isolated from plants reported since 2015.

For over a century, viruses have left a long trail of evidence implicating them as frequent suspects in the development of type 1 diabetes. Through vigorous interrogation of viral infections in individuals with islet autoimmunity and type 1 diabetes using serological and molecular virus detection methods, as well as mechanistic studies of virus-infected human pancreatic β-cells, the prime suspects have been narrowed down to predominantly human enteroviruses. Here, we provide a comprehensive overview of evidence supporting the hypothesised role of enteroviruses in the development of islet autoimmunity and type 1 diabetes. We also discuss concerns over the historical focus and investigation bias toward enteroviruses and summarise current unbiased efforts aimed at characterising the complete population of viruses (the “virome”) contributing early in life to the development of islet autoimmunity and type 1 diabetes. Finally, we review the range of vaccine and antiviral drug candidates currently being evaluated in clinical trials for the prevention and potential treatment of type 1 diabetes.

Antimicrobials have allowed medical advancements over several decades. However, the continuous emergence of antimicrobial resistance restricts efficacy in treating infectious diseases. In this context, the drug repositioning of already known biological active compounds to antimicrobials could represent a useful strategy. In 2002 and 2003, the SARS-CoV pandemic immobilized the Far East regions. However, the drug discovery attempts to study the virus have stopped after the crisis declined. Today’s COVID-19 pandemic could probably have been avoided if those efforts against SARS-CoV had continued. Recently, a new coronavirus variant was identified in the UK. Because of this, the search for safe and potent antimicrobials and antivirals is urgent. Apart from antiviral treatment for severe cases of COVID-19, many patients with mild disease without pneumonia or moderate disease with pneumonia have received different classes of antibiotics. Diarylureas are tyrosine kinase inhibitors well known in the art as anticancer agents, which might be useful tools for a reposition as antimicrobials. The first to come onto the market as anticancer was sorafenib, followed by some other active molecules. For this interesting class of organic compounds antimicrobial, antiviral, antithrombotic, antimalarial, and anti-inflammatory properties have been reported in the literature. These numerous properties make these compounds interesting for a new possible pandemic considering that, as well as for other viral infections also for CoVID-19, a multitarget therapeutic strategy could be favorable. This review is meant to be an overview on diarylureas, focusing on their biological activities, not dwelling on the already known antitumor activity. Quite a lot of papers present in the literature underline and highlight the importance of these molecules as versatile scaffolds for the development of new and promising antimicrobials and multitarget agents against new pandemic events.

Arboviral Diseases

Over the course of the last 50 years, the emergence of several arboviruses have resulted in countless outbreaks globally. With a high proportion of infections occurring in tropical and subtropical regions where arthropods tend to be abundant, Asia in particular is a region that is heavily affected by arboviral diseases caused by dengue, Japanese encephalitis, West Nile, Zika, and chikungunya viruses. Major gaps in protection against the most significant emerging arboviruses remains as there are currently no antivirals available, and vaccines are only available for some. A potential source of antiviral compounds could be discovered in natural products—such as vegetables, fruits, flowers, herbal plants, marine organisms and microorganisms—from which various compounds have been documented to exhibit antiviral activities and are expected to have good tolerability and minimal side effects. Polyphenols and plant extracts have been extensively studied for their antiviral properties against arboviruses and have demonstrated promising results. With an abundance of natural products to screen for new antiviral compounds, it is highly optimistic that natural products will continue to play an important role in contributing to antiviral drug development and in reducing the global infection burden of arboviruses.

The continuing "explosion" of scientific information and the arborization of medical specialties have caused physicians to invent names and catch phrases to define their new activities. Regrettably, much of this latter-day vocabulary is unmusical and clumsy. Some examples represent a downright assault on the English Ianguage. It is alarming that a profession whose members demand such precision in their work would tolerate such slapdash semantic shenanigans. One has winced at such utterances as "examination of the chest showed no pathology;" one has cringed when otherwise esteemed colleagues have indulged in such semantic horrors as "coagulogram" and "febrile agglutinins;" but, in years to come the one atrocity whose promulgation may be remembered with particular mal de mer by the older pediatricians will be the term "ambulatory pediatrics."

AbstractCombination therapies have become a standard for the treatment for HIV and HCV infections. They are advantageous over monotherapies due to better efficacy and reduced toxicity, as well as the ability to prevent the development of resistant viral strains and to treat viral co-infections. Here, we identify several new synergistic combinations against emerging and re-emerging viral infections in vitro. We observed synergistic activity of nelfinavir with investigational drug EIDD-2801 and convalescent serum against SARS-CoV-2 infection in human lung epithelial Calu-3 cells. We also demonstrated synergistic activity of vemurafenib combination with emetine, homoharringtonine, gemcitabine, or obatoclax against echovirus 1 infection in human lung epithelial A549 cells. We also found that combinations of sofosbuvir with brequinar and niclosamide were synergistic against HCV infection in hepatocyte derived Huh-7.5 cells, whereas combinations of monensin with lamivudine and tenofovir were synergistic against HIV-1 infection in human cervical TZM-bl cells. Finally, we present an online resource that summarizes novel and known antiviral drug combinations and their developmental status. Overall, the development of combinational therapies could have a global impact improving the preparedness and protection of the general population from emerging and re-emerging viral threats.

Aim. To assess the effectiveness of the use of the antiviral drug enisamium iodide in the complex treatment of acute respiratory viral infections (ARVI) caused by various pathogens in routine clinical practice. Materials and methods. А prospective randomized study included 134 patients who were treated in the epidemic season of influenza and ARVI in 20182019. All patients were examined for the presence of influenza A and B viruses, respiratory syncytial virus, human metapneumovirus, parainfluenza virus, coronaviruses, rhinoviruses, adenoviruses in nasopharyngeal swabs by PCR. Patients of the main group received enisamium iodide along with symptomatic therapy, the control group received only symptomatic therapy. The primary parameter of the effectiveness of therapy was evaluated on the scale of the general severity of the manifestations of ARVI (Total Symptom Score TSS) from the 2nd to the 4th day and by the secondary criteria of effectiveness: assessment of the duration of ARVI, the severity of fever, the proportion of patients with normal body temperature, the duration of the main clinical symptoms of acute respiratory viral infections, the proportion of patients in whom complications requiring antibiotics were noted, the dynamics of interferon status on the 6th day. To conduct a statistical analysis, depending on the efficiency parameter, the ANCOVA method with a fixed group factor and an initial score on the TSS severity scale was used as covariates, a criterion for comparing quantitative indicators in two independent groups. Results. According to the results of the analysis of the primary efficacy parameter, the median (interquartile range) of the average score on the scale of the general severity of ARVI manifestations in the main group was 4.33 (3.675.83), in the comparison group 6.00 (4.677.25; p0.001). The duration of systemic and local manifestations of acute respiratory viral infections was statistically significantly less in the main group (p=0.002 and p=0.019, respectively). Prescription of additional therapy was required in 2 (2.9%) patients of the main group (patients taking enisamium iodide), compared with 8 (11.9%) patients in the control group. Serum levels of interferon  and interferon  on the last day of treatment were statistically significantly higher in patients of the main group compared with the control group (p0.001). Treatment (excellent) was evaluated by 42 (62.7%) patients, while in the control group only 17 (25.8%) patients gave similar ratings. Both patients (p0.001) and doctors (p0.002) rated therapy tolerance better in the study group. Conclusion. The results confirmed the safety and effectiveness of enisamium iodide as a treatment for ARVI and influenza. The antiviral, interferonogenic and anti-inflammatory properties of the drug are involved in the formation of an antiviral response and reduce the risk of complications, which makes it possible to reduce the number of symptomatic agents used.

Coronavirus disease 19 (COVID-19) is a severe acute respiratory syndrome caused by SARS-CoV-2 (2019-nCoV). While no drugs have yet been approved to treat this disease, small molecules effective against other viral infections are under clinical evaluation for therapeutic abatement of SARS-CoV-2 infections. Ongoing clinical trials include Kaletra (a combination of two protease inhibitors approved for HIV treatment), remdesivir (an investigational drug targeting RNA-dependent RNA polymerase [RdRP] of SARS-CoV-2), and hydroxychloroquine (an approved anti-malarial and immuno-modulatory drug). Since SARS-CoV-2 replication depends on three virally encoded proteins (RdRP, papain-like proteinase, and helicase), we screened 54 FDA-approved antiviral drugs and ~3300 investigational drugs for binding to these proteins using targeted and unbiased docking simulations and computational modeling. Elbasvir, a drug approved for treating hepatitis C, is predicted to bind stably and preferentially to all three proteins. At the therapeutic dosage, elbasvir has low toxicity (liver enzymes transiently elevated in 1% of subjects) and well-characterized drug-drug interactions. We predict that treatment with elbasvir, alone or in combination with other drugs such as grazoprevir, could efficiently block SARS-CoV-2 replication. The concerted action of elbasvir on at least three targets essential for viral replication renders viral mutation to drug resistance extremely unlikely.
