Compound class: Natural product
Comment: BIO101 is pharmaceutical grade 20-hydroxyecdysone, the latter being a natural product found in the Asparagus filicinus fern, the trematode Trichobilharzia ocellata, and other organisms. Its activity as a non-peptidic activator of the class A orphan GPCR MAS1 has been proposed to offer potential clinical utility to counteract dysregulation of the renin-angiotensin system (RAS) in patients with COVID-19 respiratory failure [1-2]. Given the role of ACE2 in the RAS, and the disturbance of ACE2 function that likely ensues when SARS-CoV-2 spike protein binds to ACE2, it is feasible that the RAS will be dysregulated in COVID-19, and that ameliorating this disruption through targeted pharmacological intervention might be of potential clinical benefit.
