Oregon Health & Science University and Washington University have jointly developed new tetrahydrobenzothiophene and tetrahydropyridothiophene derivatives reported to be useful for the treatment of flavivirus and alphavirus infections.
The envelope (E) proteins of Zika virus (ZIKV) and dengue virus (DENV) present a high degree of homology, which can lead to cross-reactive antibodies that exacerbate disease through antibody-dependent enhancement. This enormously challenges the development of effective ZIKV vaccines.
Epigenic Therapeutics Co. Ltd. closed a $60 million series B round to support clinical development of lead gene therapy candidates EPI-003 for chronic hepatitis B virus and EPI-001 for hypercholesterolemia.
Several French institutions, including the University of Rennes, have prepared and tested disubstituted ferrocene complexes acting as viral replication inhibitors reported to be useful for the treatment of viral infections.
In a recent study published in Cell Reports, a team of scientists from Gilead Sciences Inc. and the University of Cincinnati detail the discovery and engineering of potent bispecific antibodies that can significantly reduce lesion development in a guinea pig model of recurrent genital herpes.
Gilead Sciences Inc. has identified 3C-like proteinase (3CLpro; Mpro; nsp5) (SARS-CoV-2; COVID-19 virus) inhibitors reported to be useful for the treatment of SARS-CoV-2 infection (COVID-19).
Researchers from the CUNY Advanced Science Research Center and their collaborators recently published a paper in Science Advances on Aug. 27, 2025, about synthetic carbohydrate receptors (SCRs) and their potential as broad-spectrum antivirals by targeting the viral envelope N-glycans. They described the antiviral activity of a series of tetrapodal SCRs both in vitro and in vivo, showing their potential as broad-spectrum inhibitors of viral infection.
Several South Korean biotech and biopharmaceutical companies completed IND submissions or won nods to start clinical trials in either the U.S. or South Korea, including SK Bioscience Co. Ltd., Genosco Inc., Pimedbio Inc., Sillajen Inc. and Ami Pharm Co. Ltd.
The vaccine dominoes continue to fall in the U.S. This time one fell on the FDA’s Vaccines and Related Biological Products Advisory Committee, as one of Health and Human Services Secretary Robert Kennedy’s most outspoken critics was removed from the panel nearly a year and a half before his term was to expire.
Researchers at the University of California, Los Angeles and collaborators have analyzed what cell types are infected by hantaviruses and how infection alters gene expression.
