R13 is a small-molecule flavonoid and orally active, potent, and selective agonist of the tropomyosin receptor kinase B (TrkB) – the main signaling receptor for the neurotrophin brain-derived neurotrophic factor (BDNF) – which is under development for the potential treatment of Alzheimer's disease.[1][2] It is a structural modification and prodrug of tropoflavin (7,8-DHF) with improved potency and pharmacokinetics, namely oral bioavailability and duration.[1] The compound is a replacement for the earlier tropoflavin prodrug R7 and has similar properties to it.[1][3] It was developed because while R7 displayed a good drug profile in animal studies, it showed almost no conversion into tropoflavin in human liver microsomes.[1] In contrast to R7, R13 is readily hydrolyzed into tropoflavin in human liver microsomes.[1]
