Description: GUN30820, also known as Brr2 inhibitor C9 or Brr2 Inhibitor 9, is an allosteric inhibitor of the spliceosomal RNA helicase Brr2. Brr2 is implicated in autosomal-dominant retinitis pigmentosa a group of progressive retinal degenerative disorders. GUN30820 was first described in Journal of Medicinal Chemistry (2017), 60(13), 5759-5771. This product has not formal name. For the convenience of scientific communication, we named it by combining its Inchi key (3 letters from the first letter of each section) with the last 5 digit of its CAS#) according to MedKoo Chemical Nomenclature (
