PKR-IN-C16 is a specific protein kinase (PKR) inhibitor.?PKR-IN-C16 is able to inhibit the autophosphorylation of PKR and unlock the translation blockade induced by PKR in primary neuronal cultures.PKR-IN-C16 binds the ATP-binding site of PKR and blocks autophosphorylation with an IC50 value of 186-210 nM.?

Remimazolam is a benzodiazepine derivative drug as an alternative to the short-acting imidazobenzodiazepine midazolam, for use in induction of anaesthesia and conscious sedation for minor invasive procedures.?Remimazolam was found to be both faster acting and shorter lasting than midazolam, and human clinical trials showed a faster recovery time and predictable, consistent pharmacokinetics, suggesting some advantages over existing drugs for these applications.?
