Summary: Yellow fever is a re-emerging major health issue causing recent outbreaks with high mortality rates, mainly affecting tropical countries in Africa and South America. The development of a multi-epitope vaccine for Yellow fever virus using immunoinformatics approaches shows potential in stimulating both humoral and cellular immune responses, making it a candidate for further experimental validation.

Summary: The yellow fever disease was prevented by two live attenuated vaccines, strains 17D and French neurotropic vaccine (FNV), derived from wild-type strains Asibi and French Viscerotropic virus (FVV) through serial passage. The genome sequence of FVV was determined after five passages in HeLa cells, and it was found that the FVV HeLa p5 virus had five amino acid substitutions compared to the parental strain. Surprisingly, the genetic diversity and Ribavirin resistance of the FVV HeLa p5 virus were not statistically different to the parental strain.

Summary: Arbovirus infections are prevalent in Africa due to the lack of established epidemiological surveillance systems and accurate differential diagnosis. Studies indicate these infections are endemic in most African countries, highlighting the need for improved monitoring to enhance diagnostic accuracy. Healthcare providers should be informed about prevalent arboviral diseases to better identify and manage possible cases.

Summary: Dengue, West Nile, and Zika viruses are vector-borne flaviviruses that cause disease outbreaks with potentially severe symptoms and socioeconomic repercussions. Currently, there are no specific treatments available, and only generic symptom relief is possible. The effectiveness of the first dengue vaccine, Dengvaxia, is limited. Prophylactic approaches against other viruses are even more restricted. Therefore, there is a need for therapeutic strategies.

Summary: This study aims to analyze the humoral immunity and cross-reactivity in dengue patients using a multiplexed protein microarray. The results show that patients with severe dengue have higher levels of IgG antibodies against multiple Flavivirus antigens. Logistic regression analysis identifies groups of markers that can effectively distinguish dengue patients from healthy controls and hospitalized patients from mild cases.

Summary: A qRT-PCR system based on TaqMan chemistry was developed to detect Saboya virus (SABV) with high specificity and sensitivity. The system reliably detected SABV strains without cross amplification of other flaviviruses. It can be easily incorporated into existing arbovirus detection assays to study virus prevalence in various samples.

Summary: As obligate intracellular parasites, viruses rely heavily on host cells for replication and dysregulate cellular processes for their benefit. The present study used RNA sequencing and mass spectrometry to investigate the complex interactions between viruses and host cells. Changes in the transcriptome and proteome of infected cells were compared to mock-infected cells, revealing significant alterations in mRNA and protein abundance, as well as modulation of alternative splicing. Interestingly, there was a disconnect between the changes in the transcriptome and those in the proteome of infected cells.

Summary: Prior studies have shown that yellow fever virus (YFV) RNA can be detected in saliva and urine as an alternative to serum. In this study, urine samples collected from yellow fever (YF) patients during acute and convalescent phases of YF infection were tested for YFV RNA. The results indicated the presence of YFV RNA in both the acute and convalescent phase samples, suggesting a prolonged period of detection beyond the viremic phase. Genotyping analysis revealed the presence of YFV South American I genotype in these samples. The use of urine samples, along with serological tests, epidemiologic inquiry, and clinical assessment, could provide a longer diagnostic window for laboratory YF diagnosis.

Summary: We developed a high-throughput screening method for antiviral drugs against SARS-CoV-2 using a fully automated robot system. This novel dual-reporter virus-cell-based imaging assay proved to be convenient and powerful for screening large compound libraries. The selected host cell subclone showed high expression of the reporter virus, resistance to virus-induced cytopathogenic effects, and strong fluorescent signals, making it suitable for high-throughput screening purposes.

Summary: DF-47 and DF-51 were identified as effective inhibitors of SARS-CoV-2/DENV polymerase through RdRp inhibition screening and in vitro antiviral study. In silico simulation revealed stable binding modes between DF-47/DF-51 and SARS-CoV-2/DENV RdRp, including chelating with Mg2+ near the polymerase active site. These polyphenols have the potential to be developed into broad-spectrum, non-nucleoside RdRp inhibitors with a new scaffold.

Summary: AL-471 is a potent inhibitor of HIV and EV-A71 entry, and our research group has made further improvements on it. The antiviral activity of the compounds seems to be largely independent of the Trp stereochemistry and is dependent on both the Trp unit and the distal isophthalic moiety. One derivative, 23 (AL-534), with the shortest alkyl urea linkage, showed subnanomolar potency against different EV-71 clinical isolates.

Summary: Infection with the rabies virus is a deadly neurological disease, but post-exposure prophylaxis (PEP) with vaccination and anti-rabies immunoglobulins (RIGs) is 100% effective if administered early. This study found that Urtica dioica agglutinin (UDA), a specific lectin, can prevent the entry of the virus into host cells and effectively stop virus replication in a muscle model. UDA holds promise as a cheap and simple alternative for RIGs in PEP.

The molecule acts at the early phase of the infection cycle by inhibiting cathepsin L. Although its activity is cell-specific, Z-Tyr-Ala-CHN2 can be a useful tool compound for studying the biology of coronavirus entry and replication.

Summary: Hepatitis E virus (HEV) is a major cause of hepatitis, with an estimated 3.3 million symptomatic cases annually. Currently, there is no specific treatment for HEV, and a vaccine is only available in China and Pakistan. To aid in the development of therapeutic and preventive strategies, convenient HEV infection models in small laboratory animals are needed.

Summary: In this study, fifteen cyanopeptolins (CPs) were isolated from the Baltic cyanobacterium Nostoc edaphicum and tested for their activity against SARS-CoV-2. The results showed that the Arg-containing CP978 exhibited the strongest inhibition of Delta SARS-CoV-2 infection, possibly through direct interaction with the virus. CP978 also showed significant reduction in virus replication in human airway epithelial cells. Among the tested SARS-CoV-2 variants, CP978 had no effect on the Wuhan variant. These findings suggest that CP978 has potential as an antiviral drug candidate.

Summary: The discovery and development of a novel small-molecule antiviral for dengue prevention or treatment is critical due to the absence of approved dengue-specific treatment. This study identified a series of 3-acyl-indole derivatives as potent dengue virus inhibitors and optimized them to improve their effectiveness against all four DENV serotypes. The optimized candidates demonstrated good chiral stability, oral bioavailability, and efficacy in treating DENV-2 infection in mice.

Summary: Breast cancer is a common malignant tumor in women, and drug resistance remains a clinical challenge. In this study, a novel compound, G-5b, was developed with potent antagonistic and degradation activities comparable to the current drug fulvestrant. G-5b also showed improved stability and solubility. Mechanistically, G-5b engages the proteasome pathway to degrade ER, inhibiting the ER signaling pathway and inducing apoptosis and cell cycle arrest. In animal models, G-5b exhibited superior pharmacokinetics and pharmacodynamics properties. Overall, G-5b is a promising long-acting SERD worthy of further investigation and optimization.

Compounds 4d-f exhibited promising cytotoxicity against hematological cells and moderate activity against solid tumor models. Compound 4d showed potent inhibition of multiple kinase targets and had stable interactions with HDAC and members of the JAK family. These compounds showed selective cytotoxicity with minimal effects on non-tumorigenic cells and favorable pharmacokinetic profiles.
