A novel class of antitumour agents. I. Chemistry and animal experiments

Newly synthesized tertiary amino steroids, among them 2 beta,16 beta-dipiperidino-5 alpha-androstane-3 alpha,17 beta-diol dipivalate (DAP), were tested in three animal species as to their antitumour activity against transplantable tumours. The acute toxicity of DAP was similar to that of cyclophosphamide and considerably lower than vinblastine. Rats with Walker ascites, treated intraperitoneally with DAP, survived up to one year without ascites; untreated animals died within 10 days of transplantation. Intragastric and intraperitoneal application of DAP caused side effects suggesting a local toxicity.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
