Simcere Zaiming Pharmaceutical Co. Ltd. has divulged 3C-like proteinase (3CLpro) (SARS-CoV-2) inhibitors reported to be useful for the treatment of respiratory tract infections.
Researchers from Infex Therapeutics Ltd. have announced the nomination of a clinical candidate for its in-house developed COV-X program. The novel first-in-class small molecule is an oral pan-coronavirus papain-like protease (PLpro) inhibitor, which was selected based on preclinical data that demonstrated in vivo efficacy of the candidate a murine model of SARS-CoV-2.
Suzhou Ark Biopharmaceutical Co. Ltd. has synthesized 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).
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).
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.
The most in-depth study to date of the genetic risk factors for long COVID has identified 73 genes that are highly associated with severe or fatigue-dominant forms of the disease. Many of these genes also are known to be associated with other disorders, including myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and neurodegenerative, autoimmune, cardiovascular and metabolic diseases.
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.
