ABCG2 contributed to cancer progression due to its active efflux of chemotherapeutic agents out of neoplastic cells (Natarajan et al., 2012). studies. In this review, an insight on sinensetin pharmacological activities and mechanisms of action serves as a useful resource for a more thorough and comprehensive understanding of sinensetin as a potential lead candidate for drug discovery. var. [syn: Benth., (Thunb.) Backer, Bakh.f. & Steenis] (Lambiaceae) and in many citrus fruits. In citrus fruits, it is particularly more abundant in the peel than other parts of the fruit (Manthey and Grohmann, 2001; Youn et al., 2017). A polymethoxylated flavonoid has a double bond between positions 2 and 3 and a ketone in position 4 of the C ring (Panche et al., 2016). Sinensetin is a pentamethoxyflavone, chemically known as 2-(3,4-dimethoxyphenyl)-5,6,7-trimethoxy-4is widely employed in traditional medicine as a diuretic (Beaux et al., 1999; Adam et al., 2009) and to treat hypertension (Mohamed et al., 2012; Manshor et al., 2013), rheumatism, tonsillitis, gout, Mitomycin C menstrual disorder and diabetes (Adam et al., 2009; Mohamed et al., 2012). The leaves of have been shown to exhibit excellent pharmacological activities such as antioxidant (Awale et Mitomycin C al., 2003), antibacterial (Ho et al., 2014), hepatoprotective (Yam et al., 2007), anti-inflammatory (Hsu et al., 2010), cytotoxic (Yam et al., 2007), antihypertensive (Azizan et al., 2012) and gastroprotective (Yam et al., 2009). Many SVIL citrus fruits have been used traditionally for many medicinal purposes. For instance, fruit peels of Blanco [syn: Hort. ex Tanaka, (Yu.Tanaka ex Swingle), Hayata, Ten.] have been used in Asian ethnomedicine to treat indigestion, bronchial, fever, snakebite, stomachache, edema, cardiac diseases, bronchitis and asthmatic conditions (Kang et al., 2013). Moreover, many species among the different variety of are recognized as food supplements and nutrition while Mitomycin C their leaf components and essential oils have shown strong pharmacological activities such as antimicrobial (Tao et al., 2014), anti-inflammatory (Nasri et al., 2017), antioxidant (Nasri et al., 2017), anticancer (Benavente-Garcia O and Castillo, 2008), antiproliferative (Du, and Chen, 2010), hypoglycemic (Aruoma et al., 2012) and analgesic effects (Nasri et al., 2017). There were several reports within the isolation of sinensetin from using silica column, sephadex LH-20 column and preparative TLC. Another study reported that from 1?kg of varieties. Out of 100?mg ethyl acetate extract of (500?g of dry excess weight) yielded 38.8?mg of sinensetin by using silica gel column chromatography (Nagase et al., 2005). subjected to high-speed counter current chromatography (HSCCC) separation and preparative high performance liquid chromatography (HLPC) yielded 27.7?mg of sinensetin (Du and Chen, 2010). Polymethoxyflavone-enriched draw out of Nice Portuguese oranges (Newhall variety), acquired by supercritical fluid technology contained sinensetin at 17.36?mg/g while determined by HPLC with diode array detection (HPLC-UV/DAD) (Pereira et al., 2019). Sinensetin was the second most abundant methoxylated flavonoids isolated from 1?kg peels of (L.) Osbeck (Malterud and Rydland, 2000). Iwase et al. (2000), reported that from dried peels (955?g) of 13.4?mg sinensetin was isolated. Sinensetin is also available like a synthetic compound as it can be commercially prepared. Amzad Hossain and Ismail (2004) reported synthesis of sinensetin in high yield by alkaline condensation of 2,4,5,6-tetrahydroxyacetophenone and 3,?4-di (methoxymethoxy) benzaldehyde to give 2,?4,?5,?6,?3,?4-hexa (methoxymethoxy) chalcone, followed by dimethoxymethylation in acid medium and treatment Mitomycin C with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone to yield 5,6,7,3,4-pentahydroxyflavone. Sinensetin was acquired by methylation of 5,6,7,3,4-pentahydroxyflavone using dimethyl sulphate and potassium carbonate. Pharmacological Activities and Mechanisms of Action With this review, an updated overview of the pharmacological activities of sinensetin such as anticancer, anti-inflammatory, antioxidant, antimicrobial, anti-obesity, anti-dementia, vasorelaxant and antitrypanosomal activities and their underlying mechanisms of action are offered. The databases employed for data collection are primarily from Google Scholar, PubMed, Scopus and Science Direct.
