Shanghai Curegene Pharmaceutical Co. Ltd. has synthesized macrocyclic compounds acting as 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).
Taking strides from its start as a Seoul National University laboratory, South Korea’s Cellid Co. Ltd. said July 24 that the MFDS approved an IND for the global phase III trial for its omicron variant-targeting COVID-19 vaccine called AdCLD-CoV19-1 OMI. Approval from the MFDS comes two months after Cellid filed the IND on May 23 for its adenovirus vector platform vaccine “capable of responding quickly to virus mutations,” the company said.
A day after a U.S. House committee, on a party-line vote, advanced two bills to reauthorize emergency preparedness programs, the Senate Health, Education, Labor and Pensions (HELP) Committee voted 17-3 July 20 to send its bipartisan reauthorization of the Pandemic and All Hazards Preparedness Act to the Senate floor with a do-pass recommendation.
Immunic AG has identified deuterated dihydroorotate dehydrogenase (DHODH) inhibitors containing a carboxylic acid bioisostere. They are reported to be useful for the treatment of Crohn’s disease, influenza, lupus erythematosus, multiple sclerosis, psoriasis, rheumatoid arthritis, SARS-CoV-2 infection (COVID-19) and cancer, among others.
Since its emergence in late 2019, SARS-CoV-2 has killed nearly 7 million people. But at the same time, many infections, in particular in children and young adults, are asymptomatic with rapid viral clearance from the body. It remains unclear why many individuals are able to successfully clear infection without major complications while others develop severe disease, even without known risk factors for severe COVID-19 outcomes.
Now, a new study involving nearly 30,000 individuals has found that variation in the human leukocyte antigen (HLA) loci may underlie processes mediating asymptomatic infection. The findings were reported in the July 19, 2023, online edition of Nature.
Research at Pharmablock Sciences (Nanjing) Inc. has led to the development of spirooxindole compounds acting as 3C-like proteinase (3CLpro; Mpro; nsp5) (SARS-CoV-2; COVID-19 virus) inhibitors and thus reported to be useful for the treatment of viral infections.
The protection against SARS-CoV-2 provided by spike-based vaccines, although effective, tends to decrease as the virus evolves and new variants of concern appear. Researchers from Osivax SAS reported the first results on cross-protection with OVX-033, a new human SARS-CoV-2 vaccine generated via the oligoDOM platform.
The search for novel therapies that complement vaccine-induced immune protection against SARS-CoV-2 continues. In previous work, researchers at QIMR Berghofer Medical Research Institute and collaborators developed a cell-permeable and highly selective peptide called NACE2i, targeting nuclear angiotensin-converting enzyme 2 (ACE2). In particular, NACE2i spans and targets the ACE2 nuclear localization signal motif, successfully inhibiting nuclear translocation of ACE2 and viral replication in human cell lines infected with SARS-CoV-2.
Helmholtz Zentrum Dresden Rossendorf has patented 3-((3-([1,1’-biphenyl]-3-ylmethoxy)phenoxy)methyl)benzonitrile derivatives that are radiolabeled compounds targeting programmed cell death 1 ligand 1 (PD-L1; CD274). They are reported to be potentially useful for the diagnosis and/or radionuclide therapy treatment of cancer and SARS-CoV-2.
