TL;DR: Wang et al. as discussed by the authors showed that Chuju is an ideal source of natural flavonoids with significant antioxidant and anti-inflammatory effects, and is worthy of further development as health-promoting food or supplement.
Abstract: Chuju, the flower of Chrysanthemum morifolim cv. Chuju, is a traditional medicine-food material used in China. Bioassay-guided chemical investigation on Chuju led the isolation of 16 flavonoids ( 1-16 ) characterized as quercetin ( 1 ), isorhamnetin 3- O -β-D-glucoside ( 2 ), eriodictyol ( 3 ), pyracanthoside ( 4 ), apigenin ( 5 ), apigetrin ( 6 ), acacetin ( 7 ), acacipetalin ( 8 ), luteolin ( 9 ), diosmetin ( 10 ), spinacetin ( 11 ), axillarin ( 12 ), bonanzin ( 13 ), cirsiliol ( 14 ), chrysosplenol D ( 15 ) and artemetin ( 16 ). Among them, compounds (11-16) were first reported from the Chrysanthemum species. Chuju flavonoids displayed strong antioxidant in DPPH (1, 1-diphenyl-2- picrylhydrazyl) radical scavenging assay, and high anti-inflammatory activity by inhibiting NO production in LPS-induced RAW 264.7 cells. These findings suggests that Chuju is an ideal source of natural flavonoids with significant antioxidant and anti-inflammatory effects, and is worthy of further development as health-promoting food or supplement.

TL;DR: It is found that acacetin inhibits p38 and JNK phosphorylation and reduces M MP‐1, MMP‐3 and MMP-13 expression in interleukin‐1β‐induced FLSs, suggesting that ac acetin has antiarthritic effects in FLSS.
Abstract: It is well known that rheumatoid arthritis (RA) is an autoimmune joint disease in which fibroblast-like synoviocytes (FLSs) play a pivotal role. In this study, we investigated the anti-arthritic properties of acacetin in FLSs. The expression of matrix metalloproteinase (MMP)-1, MMP-3 and MMP-13 were investigated by quantitative RT-PCR and western blot at gene and protein levels. At the same time, the phosphorylation of mitogen-activated protein kinases (MAPK) was investigated. The DNA-binding activity of NF-κB was investigated by electrophoretic mobility shift assay. We found that acacetin inhibits p38 and JNK phosphorylation and reduces MMP-1, MMP-3 and MMP-13 expression in interleukin-1β-induced FLSs. Our results suggest that acacetin has antiarthritic effects in FLSs. Thus, acacetin should be further studied for the treatment of arthritis.

TL;DR: In this article, the efficiency of three different solvents (H2O, acidified H2O and 70% Methanol) for metabolites extraction from the leaves of sugar beet (Beta vulgaris subsp. rubra) was investigated along with their inhibitory activity on pancreatic α-amylase and lipase for obesity management.

TL;DR: The preclinical study indicates that the synthesized acacetin prodrug is highly water-soluble and safe; it effectively terminates experimental AF in beagle dogs and therefore may be a promising drug candidate for clinical trial to treat patients with acute AF.
Abstract: We previously reported that duodenal administration of the natural flavone acacetin can effectively prevent the induction of experimental atrial fibrillation (AF) in canines; however, it may not be used intravenously to terminate AF due to its poor water-solubility. The present study was to design a water-soluble prodrug of acacetin and investigate its anti-AF effect in beagle dogs. Acacetin prodrug was synthesized by a three-step procedure. Aqueous solubility, bioconversion and anti-AF efficacy of acacetin prodrug were determined with different methodologies. Our results demonstrated that the synthesized phosphate sodium salt of acacetin prodrug had a remarkable increase of aqueous solubility in H2O and clinically acceptable solution (5% glucose or 0.9% NaCl). The acacetin prodrug was effectively converted into acacetin in ex vivo rat plasma and liver microsome and in vivo beagle dogs. Intravenous infusion of acacetin prodrug (3, 6 and 12 mg/kg) terminated experimental AF without increasing ECG QTc interval in beagle dogs. The intravenous LD50 of acacetin prodrug was 721 mg/kg in mice. Our preclinical study indicates that the synthesized acacetin prodrug is highly water-soluble and safe; it effectively terminates experimental AF in beagle dogs and therefore may be a promising drug candidate for clinical trial to treat patients with acute AF.
