Apigenin is a common dietary flavonoid that is abundantly present in many fruits, vegetables and Chinese medicinal herbs and serves multiple physiological functions, such as strong anti-inflammatory, antioxidant, antibacterial and antiviral activities and blood pressure reduction. Therefore, apigenin has been used as a traditional medicine for centuries. Recently, apigenin has been widely investigated for its anti-cancer activities and low toxicity. Apigenin was reported to suppress various human cancers in vitro and in vivo by multiple biological effects, such as triggering cell apoptosis and autophagy, inducing cell cycle arrest, suppressing cell migration and invasion, and stimulating an immune response...

Considerable attention has been paid to the introduction of novel naturally occurring plant-derived radiosensitizer compounds in order to augment the radiation efficacy and improve the treatment outcome of different tumors. This study was therefore undertaken to evaluate the antitumor, antiangiogeneic, and synergistic radiosensitizing effects of apigenin, a dietary flavonoid, and/or cryptotanshinone, a terpenoid isolated from the roots of Salvia miltiorrhiza, against the growth of solid Ehrlich carcinoma in female mice...

Eriocauli Flos (Gujingcao; EF), the dried capitulum with the peduncle of Eriocaulon buergerianum Koern. (Eriocaulaceae), is a Chinese herbal medicine for treating eye diseases and inflammation. However, several species of the Eriocaulon genus are used as substitutes in different areas. To examine the species of EF used in Taiwan and to establish the quality control platform, morphological and chemical analyses have been performed. Ten major compounds, including apigenin (7) and its 7-O-β-D-glucopyranoside (1) and 7-O-(6-O-E-coumaroyl)-β-D-glucopyranoside (6), hispidulin (8) and its 7-O-β-D-glucopyranoside (2) and 7-O-(6-O-E-coumaroyl)-β-D-glucopyranoside (5), jaceosidin (9) and its 7-O-β-D-glucopyranoside (3), and toralactone (10) and its 9-O-β-D-glucopyranosyl(1→6)-β-D-glucopyranoside (4), were isolated and identified from commercially available EF...

The synthesized flavonoid derivatives were examined for their antioxidant, anti-inflammatory, xanthine oxidase (XO), urease inhibitory activity, and cytotoxicity. Except few, all the flavonoids under this study showed significant antioxidant activity (45.6%-85.5%, 32.6%-70.6%, and 24.9%-65.5% inhibition by DPPH, ferric reducing/antioxidant power, and oxygen radical absorption capacity assays) with promising TNF-α inhibitory activity (42%-73% at 10 μM) and IL-6 inhibitory activity (54%-81% at 10 μM) compared with that of control dexamethasone...

SCOPE: We investigated whether apigenin protected against skeletal muscle atrophy induced by obesity. METHODS AND RESULTS: Mice were fed a high fat diet (HFD) for 9 wks to induce obesity, and then were assigned to two groups; the HFD group received a high fat diet, and the HFD+AP group received a 0.1% apigenin-containing HFD. After additional feeding of the experimental diet for 8 wks, mice in the HFD group were highly obese compared with the mice in the standard diet fed mice group...

Fruits and vegetables are an important source of dietary antioxidants and epidemiological studies show that their regular intake in the diet may decrease the risk of several chronic diseases. Phoenix dactylifera L. (date palm or dates) is an important crop, widely used in the Arabian region and in other parts of the world as a food and also in folk medicine, due to its health-promoting properties. Antioxidant phytochemicals present in plant foods are partly responsible for such health benefits. The antioxidants present in dates are mainly phenolics, like flavonoids and phenolic acids...

This study aimed to investigate the protective effects of apigenin (AP), a flavonoid found in plants, against acrylonitrile (ACN)-induced subchronic sperm and testes injury in rats. Male Sprague-Dawley rats were randomly divided into four groups: a control group (corn oil), an ACN group (ACN 50 mg kg(-1)), an ACN + AP1 group (ACN + AP 234 mg kg(-1)), and an ACN + AP2 group (ACN + AP 468 mg kg(-1)). The ACN + AP group received AP by gavage after treatment with 50 mg kg(-1) ACN for 30 min, whereas the rats in the control group were given an equivalent volume of corn oil...

We aimed to construct a novel nano-assembly carrying apigenin (APG), a hydrophobic drug, and to evaluate its in vitro targeting ability for A549 cells overexpressing CD44 receptors. The apigenin-loaded sodium hyaluronate nano-assemblies (APG/SH-NAs) were assembled by multiple non-covalent interactions between sodium hyaluronate (SH) and APG. The prepared APG/SH-NAs exhibited a small average size and narrow particle size distribution. In addition, satisfactory encapsulation efficiency and drug loading were obtained...

The aim of our study is to investigate the protective effect of apigenin and the role of the JAK2/STAT3 signaling pathway in renal ischemia/reperfusion injury (IRI) in rats. For in vivo experiments, rat kidneys were subjected to 45min of ischemia, followed by 24h of reperfusion. The kidneys were pretreated for 24h with apigenin (4mg/kg) intraperitoneally in the absence or presence of the JAK2 kinase-specific inhibitor AZD1480 (30mg/kg). The serum creatinine and urea nitrogen levels were analyzed. Histologic examinations were evaluated...

Five main flavonoids of Hebei Xiangju were studied using the Density Functional Theory (DFT) B3LYP method with 6-311 G (d) basis set.Their activities were analyzed based on molecular structure,bond dissociation energy (BDE),natural orbital charge distribution (NBO),bond order and the energy gap between HOMO and LUMO. The results showed that the existing of intra molecular hydrogen bond in B ring can improve the antioxidant activity of the flavonoids, at the same time, the hydroxyl groups on the glycosides do not have the activity of eliminating free radicals, but decrease the total molecular antioxidant activity...

Tibial dyschondroplasia (TD) is one of the common skeletal abnormalities in fast-growing birds, and it is characterized by nonvascularized, unmineralized, and nonviable cartilage in the tibial growth plate that fails to form bone. The aim of this study was to check the in vitro effect of apigenin and danshen on heat-shock protein 90 (Hsp90) and vascular endothelial growth factor (VEGF) expressions in avian growth plate cells treated with sublethal concentration of thiram. Initially, chondrocytes from chicken growth plates were isolated on culturx ed medium with and without various concentration of thiram to determine the sublethal dose...

This study shows the effects of spices, and their phenolic and flavonoid compounds, on prostate cell lines (PNT1A, 22RV1 and PC3). The results of an MTT assay on extracts from eight spices revealed the strongest inhibitory effects were from black pepper and caraway seed extracts. The strongest inhibitory effect on prostatic cells was observed after the application of extracts of spices in concentration of 12.5 mg·mL(-1). An LC/MS analysis identified that the most abundant phenolic and flavonoid compounds in black pepper are 3,4-dihydroxybenzaldehyde and naringenin chalcone, while the most abundant phenolic and flavonoid compounds in caraway seeds are neochlorogenic acid and apigenin...

This study was performed to investigate the antioxidant activities of Nymphaea nouchali flower (NNF) extract and the underlying mechanism using RAW 264.7 cells. The presence of gallic acid, catechin, epicatechin, epigallocatechin, epicatechin gallate, caffeic acid, quercetin, and apigenin in the NNF was confirmed by high-performance liquid chromatography (HPLC). The extract had a very potent capacity to scavenge numerous free radicals. NNF extract was also able to prevent DNA damage and quench cellular reactive oxygen species (ROS) generation induced by tert-Butyl hydroperoxide (t-BHP) with no signs of toxicity...

BACKGROUND: Oxidative stress is one of the key components of the pathology of various neurodegenerative disorders. Parkinson's disease (PD) is characterized by the progressive loss of dopaminergic neurons owing to the aggregation of alpha-synuclein (αS) in the brain. A number of polyphenols have been reported to inhibit the αS aggregation resulting in the possible prevention of PD. The involvement of free radicals in mediating the neuronal death in PD has also been implicated. METHODS: In the present study, the transgenic flies expressing human αS in the brain were exposed to 10 μM, 20 μM, 40 μM, and 80 μM of apigenin established in diet for 24 days...
