Definition

ChEBI: Phloretin is a member of the class of dihydrochalcones that is dihydrochalcone substituted by hydroxy groups at positions 4, 2', 4' and 6'. It has a role as a plant metabolite and an antineoplastic agent. It is functionally related to a dihydrochalcone.

General Description

Phloretin is a dihydrochalcone flavonoid with antioxidant activity usually found in apples and apple-derived products. It is extensively used for peroxynitrite scavenging and the inhibition of lipid peroxidation. It has been found to inhibit the growth of several cancer cells and induce apoptosis of B16 melanoma and HL60 human leukemia cells.

Biological Activity

phloretin is a dihydrochalcone, a type of natural phenols which can be found in apple tree leaves and manchurian apricot. phloretin inhibits the active transport of glucose into cells via sodium-glucose linked transporter (sglt) 1 and 2 with ic50 value of 49±12 μm [2].sglts are a family of glucose transporter which is found in the small intestine mucosa (sglt 1) and nephron proximal tubule (sglt 2). they contribute to the renal glucose reabsorption.after treatment of phloretin, differentiated 3t3-l1 cells exhibited significantly enhanced glycerol and the inhibition of adipogenesis-related transcription factor that were regulated by sglts. additionally, phloretin promoted phosphorylation of amp-activated protein kinase and increased activity of adipose triglyceride lipase and hormone-sensitive lipase [1]. when raw 263.7 cells were cultured from differentiated 3t3-l1 cell media, pt suppressed the sglt-associated nuclear transcription factor kappab and mitogen-activated protein kinase pathways [1].in streptozotocin-induced rat model of diabetes type i, oral administration of phloridzin (5/10/20/40 mg/kg/day) resulted in signi?cant reduction of blood glucose levels and improved dyslipidemia. additionally, administration of phloridzin reduced urine volume and water intake in a dose-dependent manner [3].

Biochem/physiol Actions

Reacts with vic-dicarbonyl compounds such as glyoxal and methylglyoxal, preventing cytotoxic conjugation with biological macromolecules.

Purification Methods

Crystallise phloretin from aqueous EtOH. [Zemplen & Bognár Chem Ber 75 1040 1942, Zemplén Chem Ber 76 386 1943, Beilstein 8 IV 3518.]

Neuroprotective Effects of Trilobatin, a Novel Naturally Occurring Sirt3 Agonist from Lithocarpus polystachyus Rehd., Mitigate Cerebral Ischemia/Reperfusion Injury: Involvement of TLR4/NF-κB and Nrf2/Keap-1 Signaling

Chen, Nana,Gao, Jianmei,Gong, Qihai,Lei, Yaying,Li, Na,Shi, Jingshan,Wang, Wei,Xu, Fan

, p. 117 - 143 (2020)

Aims: Neuroinflammation and oxidative stress are deemed the prime causes of brain injury after cerebral ischemia/reperfusion (I/R). Since the silent mating-type information regulation 2 homologue 3 (Sirt3) pathway plays an imperative role in protecting against neuroinflammation and oxidative stress, it has been verified as a target to treat ischemia stroke. Therefore, we attempted to seek novel Sirt3 agonist and explore its underlying mechanism for stroke treatment both in vivo and in vitro. Results: Trilobatin (TLB) not only dramatically suppressed neuroinflammation and oxidative stress injury after middle cerebral artery occlusion in rats, but also effectively mitigated oxygen and glucose deprivation/reoxygenation injury in primary cultured astrocytes. These beneficial effects, along with the reduced proinflammatory cytokines via suppressing Toll-like receptor 4 (TLR4) signaling pathway, lessened oxidative injury via activating nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathways, in keeping with the findings in vivo. Intriguingly, the TLB-mediated neuroprotection on cerebral I/R injury was modulated by reciprocity between TLR4-mediated neuroinflammatory responses and Nrf2 antioxidant responses as evidenced by molecular docking and silencing TLR4 and Nrf2, respectively. Most importantly, TLB not only directly bonded to Sirt3 but also increased Sirt3 expression and activity, indicating that Sirt3 might be a promising therapeutic target of TLB. Innovation: TLB is a naturally occurring Sirt3 agonist with potent neuroprotective effects via regulation of TLR4/nuclear factor-kappa B and Nrf2/Kelch-like ECH-associated protein 1 (Keap-1) signaling pathways both in vivo and in vitro. Conclusion: Our findings indicate that TLB protects against cerebral I/R-induced neuroinflammation and oxidative injury through the regulation of neuroinflammatory and oxidative responses via TLR4, Nrf2, and Sirt3, suggesting that TLB might be a promising Sirt3 agonist against ischemic stroke.

Novel compound from plasma-treated phloridzin and anti-obesity composition comprising the same as effective component

-

Paragraph 0039-0042, (2019/08/16)

The present invention relates to a novel compound derived from plasma-treated phloridzin and an anti-obesity composition comprising the same as an effective component and, more specifically, to a diameric compound derived from phloridzin, which is newly formed by plasma-treating phloridzin (methylene-bis-phloridzin, diglucosyl-methylene-bis-phloridzin, and methylene-bis-phloretin), and to an anti-obesity composition comprising the same as an effective component. In particular, the compound derived from phloridzin, comapred to phloridzin, inhibits the activity of pancreatic lipase and enhances the effect of suppressing fat accumulation during differentiation of fat cells. In particular, the methylene-bis-phloretin of the present invention, a diameric body formed by phloretin using a methyl group, a form of which sugars are removed from phloridzin, has excellent inhibitory effect on fat accumlation as compared to phloretin, and thus may be beneficially used as a material for anti-obesity therapeutic agents or anti-obesity functional health foods.COPYRIGHT KIPO 2019

Targeting type 2 diabetes with c-glucosyl dihydrochalcones as selective sodium glucose co-transporter 2 (sglt2) inhibitors: Synthesis and biological evaluation

Jesus, Ana R.,Vila-Vi?osa, Diogo,Machuqueiro, Miguel,Marques, Ana P.,Dore, Timothy M.,Rauter, Amélia P.

, p. 568 - 579 (2017/02/05)

Inhibiting glucose reabsorption by sodium glucose co-transporter proteins (SGLTs) in the kidneys is a relatively new strategy for treating type 2 diabetes. Selective inhibition of SGLT2 over SGLT1 is critical for minimizing adverse side effects associated with SGLT1 inhibition. A library of C-glucosyl dihydrochalcones and their dihydrochalcone and chalcone precursors was synthesized and tested as SGLT1/SGLT2 inhibitors using a cell-based fluorescence assay of glucose uptake. The most potent inhibitors of SGLT2 (IC50 = 9.23 nM) were considerably weaker inhibitors of SGLT1 (IC50 = 10.19 μM). They showed no effect on the sodium independent GLUT family of glucose transporters, and the most potent ones were not acutely toxic to cultured cells. The interaction of a C-glucosyl dihydrochalcone with a POPC membrane was modeled computationally, providing evidence that it is not a pan-assay interference compound. These results point toward the discovery of structures that are potent and highly selective inhibitors of SGLT2.

Flavonoids are a large group of plant secondary metabolites with a variety of biological properties and are therefore of interest to many scientists, as they can lead to industrially interesting intermediates. The anaerobic gut bacterium Eubacterium ramulus can catabolize flavonoids, but until now, the pathway has not been experimentally confirmed. In the present work, a chalcone isomerase (CHI) and an enoate reductase (ERED) could be identified through whole genome sequencing and gene motif search. These two enzymes were successfully cloned and expressed in Escherichia coli in their active form, even under aerobic conditions. The catabolic pathway of E. ramulus was confirmed by biotransformations of flavanones into dihydrochalcones. The engineered E. coli strain that expresses both enzymes was used for the conversion of several flavanones, underlining the applicability of this biocatalytic cascade reaction.
