“…Rutaecarpine [8,13-dihydroindolo (2',3': 3,4) pyrido (2,1-b) quinazolin-5 (7H)-one, RUT, 1, Figure 1] is a pentacyclic indolopyridoquinazolinone first isolated by Asahina and Kashiwaki from Evodia rutaecarpa (Qiu, 2012), which is one of the most frequently used traditional Chinese herbs for treating diverse ailments, including headaches, gastrointestinal disorders, postpartum hemorrhage, amenorrhea, difficult menstruation, and other diseases (Lee et al, 2008;Liao et al, 2011). As one of the most abundant compounds in Evodia rutaecarpa, RUT has also been demonstrated to possess a broad spectrum of intriguing pharmacological activities, including anti-inflammation (Moon et al, 1999), anti-platelet (Sheen et al, 1996;Sheu et al, 1996), vasodilatory (Chiou et al, 1994;Li et al, 2021), analgesic (Zhang et al, 2017;Zhang et al, 2020), cytotoxic (Byun et al, 2022;Chan et al, 2022), anti-AD (Zhao et al, 2021), and anti-obesity activities (Kim et al, 2009), as well as antidiabetic potential (Surbala et al, 2020;Xie et al, 2020). Nevertheless, RUT is still unsuitable for direct clinical application due to its poor water solubility, moderate potency, or cytotoxicity (Lee et al, 2017;Luo et al, 2020).…”
