Cocrystal Pharma Inc. announced the company has selected its broad-spectrum 3CL protease inhibitor CDI-988 for development as a potential oral therapy for norovirus.
Researchers from University of Toronto and affiliated organizations have presented the discovery and preclinical evaluation of novel inhibitors of fungal fatty acid biosynthesis as potential antifungal agents. High-throughput screening of a library of natural products against representative isolates of four major human pathogenic yeast species (Candida albicans, C. glabrata, C. auris, C. neoformans) resulted in the discovery of the triazenyl indole NPD-6433.
An experimental vaccine that contained antigens of both lytic and latent phases of Epstein-Barr virus (EBV), and induced both an antibody and a T cells response, was able to generate broad and long-lasting immunity against EBV in mouse models of infection. Researchers from the QIMR Berghofer Medical Research Institute and Elicio Therapeutics Inc. reported those results online in Nature Communications on Aug. 8, 2023.
For some viruses, the challenge to developing a vaccine is their rapid mutation rate. This is the major challenge to developing an HIV vaccine or a universal flu vaccine. EBV is different. Its superpower is its ability to hide.
For people living with HIV, the single greatest achievement to date has been the emergence of antiretroviral treatments (ART) that completely block the virus, resulting in reduced mortality and morbidity and improved quality of life. But taking one pill a day for life cannot be the end of this journey, speakers said during the International AIDS Society meeting held July 23 to 26 in Brisbane, Australia.
Human schistosomiasis is caused by parasitic flatworms in the genus Schistosoma, with the three major species that cause this disease being S. mansoni, S. haematobium, and S. japonicum. In the current study, researchers from University of Texas Health Science Center San Antonio presented preclinical data for novel oxamniquine (OXA) derivatives as potential new candidates for the treatment of this neglected tropical disease.
It has gone unnoticed in HIV research until now, but a transcriptomic analysis has detected a molecule that could kill this virus. Scientists at a U.S. military research institute laboratory have found a common factor in human cells that inhibited the replication of HIV-1 in people living with the virus. “Without any manipulation of cells in people with HIV, we have found a host factor that is inhibiting HIV in vivo,” the senior author Rasmi Thomas, chief of the Laboratory of Integrative Multiomics at Walter Reed Army Institute of Research, told BioWorld. Using single cell RNA sequencing (scRNA-seq), the study published on Aug. 2, 2023, in Science Translational Medicine identified this host factor as prothymosin α, a protein isolated from the thymus in 1966 and described in 1984.
Centre Hospitalier Regional Universitaire de Lille and Centre National de la Recherche Scientifique have patented norbornene analogues reported to be useful for the treatment of tuberculosis.
A study of the genetic determinants of HIV viral load in 3,879 people of African ancestries has found what is claimed to be the only new variant related to HIV infection discovered in more than two decades of research into how host genomics affects the response to the retrovirus.
For people living with HIV, the single greatest achievement to date has been the emergence of antiretroviral treatments (ART) that completely block the virus, resulting in reduced mortality and morbidity and improved quality of life. But taking one pill a day for life cannot be the end of this journey, speakers said during the International AIDS Society meeting held July 23 to 26 in Brisbane, Australia. Even with the success of ART, drug adherence remains a problem due to pill fatigue or depression and other mental health conditions, as well as drug-drug interactions, said Claudia Cortes, associate professor at the University of Chile in Santiago. New drugs that are longer lasting, more convenient, and affordable are desperately needed, she said.
Researchers from Laboratoire Biodim presented the discovery of novel HIV-1 integrase-LEDGF allosteric inhibitors (INLAIs), designed to share the binding site on the viral protein with the host factor LEDGF/p75. INLAIs act as molecular glues to promote hyper-multimerization of HIV-1 integrase protein to produce defective progeny virions, and as such, severely disrupt maturation of viral particles.
