Dihydrochalcones in Sweet Tea: Biosynthesis, Distribution and Neuroprotection Function. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27248794. [PMID: 36557927 PMCID: PMC9782792 DOI: 10.3390/molecules27248794] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Revised: 12/08/2022] [Accepted: 12/09/2022] [Indexed: 12/14/2022]
Abstract
Sweet tea is a popular herbal drink in southwest China, and it is usually made from the shoots and tender leaves of Lithocarpus litseifolius. The sweet taste is mainly attributed to its high concentration of dihydrochalcones. The distribution and biosynthesis of dihydrochaldones in sweet tea, as well as neuroprotective effects in vitro and in vivo tests, are reviewed in this paper. Dihydrochalones are mainly composed of phloretin and its glycosides, namely, trilobatin and phloridzin, and enriched in tender leaves with significant geographical specificity. Biosynthesis of the dihydrochalones follows part of the phenylpropanoid and a branch of flavonoid metabolic pathways and is regulated by expression of the genes, including phenylalanine ammonia-lyase, 4-coumarate: coenzyme A ligase, trans-cinnamic acid-4-hydroxylase and hydroxycinnamoyl-CoA double bond reductase. The dihydrochalones have been proven to exert a significant neuroprotective effect through their regulation against Aβ deposition, tau protein hyperphosphorylation, oxidative stress, inflammation and apoptosis.

Abstract
Although naturally occurring flavonoids have shown beneficial effects on the side effects caused by cisplatin, there are few reports on the protective effect of dihydrochalcone on the cisplatin-induced toxicity. Trilobatin (TLB), as the major sweetener and active ingredient in Lithocarpus polystachyus Rehd, is a dihydrochalcone-like compound that can be present in concentrations of up to 10% or more in tender leaves. Herein, a cisplatin-induced acute kidney injury (AKI) model was established to investigate the protective effect and mechanism of TLB against the cisplatin-induced nephrotoxicity in mice. The results showed that TLB significantly reversed the inhibition of CRE, BUN, and MDA levels compared with the cisplatin group. Furthermore, TLB treatment (50 and 100 mg/kg) for 10 days significantly alleviated cisplatin-induced renal pathological changes. TUNEL staining showed that TLB administration can effectively improve the occurrence of apoptosis of renal tissue cells caused by cisplatin exposure. Importantly, western blot analysis verified that TLB alleviated cisplatin-induced nephrotoxicity by regulating the AKT/MAPK signaling pathway and apoptosis. In summary, our findings showed clearly that TLB has a significant preventive effect on cisplatin-induced AKI.

Abstract
Three new phlorizin derivatives, 6"-O-vanilloylphlorizin (1), 6"-O-(4-hydroxybenzoyl)phlorizin (2), 6"-O-feruloylphlorizin (3), along with four known dihydrochalcones, phlorizin (4), 3-hydroxyphlorizin, trilobatin, and 6"-O-acetylphlorizin were isolated from the leaves of Lithocarpus litseifolius. Their structures were established by analysis of extensive spectroscopic data. The new compounds were shown to be non-cytotoxic when tested against A549, HeLa, HepG2, and MCF-7 cell lines.

Abstract
Acetaminophen (APAP)-induced acute liver injury (ALI) is a health issue that has gradually attracted attention, and is often regarded as a model of drug-induced hepatotoxicity. The leaves of Lithocarpus polystachyus Rehd. (named as “sweet tea”, ST) usually serve as tea drink and folk medicine for healthcare in the southwest part of China. In previous reports, it has been proven to protect various animal models, except for APAP-induced liver injury model. Therefore, this study initially explored the protective effect of ST leaf extract (STL-E) on hepatotoxicity induced by APAP in ICR mice. STL-E of 50 and 100 mg kg−1 were given to each group for 7 days. ALI was intraperitoneally induced by APAP treatment (i.p. 250 mg per kg body weight). Biochemical markers, levels of inflammatory factors, histopathological staining and western blotting were used to analyze the inflammation and apoptosis of liver tissues. Interestingly, the treatment with STL-E significantly attenuated APAP-induced liver injury (p < 0.05). Moreover, STL-E partially mitigated APAP-induced liver injury by effectively activating the PI3K/Akt pathway and inhibiting the NF-κB pathway. In a word, STL-E protected liver against APAP-induced hepatotoxicity by inhibiting the PI3K/Akt-mediated apoptosis signal pathway and inhibiting the NF-κB-mediated signaling pathway. Acetaminophen (APAP)-induced acute liver injury (ALI) is a health issue that has gradually attracted attention, and is often regarded as a model of drug-induced hepatotoxicity.![]()
