Use of Apigenin
Apigenin is a competitive CYP2C9 inhibitor with a Ki of 2 μM.
|Description||Apigenin is a competitive CYP2C9 inhibitor with a Ki of 2 μM.|
Ki: 2 μM (CYP2C9)
|In Vitro||Apigenin inhibits cytochrome P450 2C9 (CYP2C9) with a Ki of 2 μM in the CYP2C9 RECO system (a purified, reconstituted enzyme system containing recombinant human CYP2C9, P450 reductase, cytochrome b5, and liposomes). Apigenin inhibits the cell proliferation. The growth inhibition rate (IR) of 20, 40, and 80 μM of Apigenin is 38%, 71%, and 99% respectively on the 7thd. after exposure to Apigenin for 24 or 48 h, the clone formation of SGC-7901 cells is suppressed in a dose- and time-dependent manner. The cloning efficiency in 80 μM is 9.8% and 5% after treatment with Apigenin for 24 and 48 h, while in the control group it is 40.4% and 43.4%.|
|In Vivo||Apigenin (API), a natural flavonoid, possesses a broad spectrum of biological properties, including antioxidative, anti-inflammatory, anticancer, and neuroprotective effects. Apigenin (125 mg/kg and 250 mg/kg) alleviates Adriamycin (ADR) (24 mg/kg)-induced myocardial injury. Apigenin inhibits serum aspartate amino transferase (AST) release. Apigenin reduces serum lactate dehydrogenase (LDH) release. Apigenin reduces serum creatine kinase (CK) contents.|
DMSO : ≥ 30 mg/mL (111.01 mM)
* "≥" means soluble, but saturation unknown.
|Cell Assay||The effect of Apigenin on the viability of cells is determined by MTT assay. Near-confluent stock cultures of human gastric cancer SGC-7901 cells are harvested with 0.2% EDTA and plated at a density of 2.5×103/well in 96-well microtiter plates. After an overnight incubation to allow cell attachment, the medium is replaced by fresh medium containing different concentrations (0, 20, 40, and 80 μM) of Apigenin. Control wells receive DMSO (0.2%). Each concentration of Apigenin is repeated in four wells. After incubation for 24 h, one plate is assayed with a microplate reader at the wavelength of 570 nm. Before the assay, MTT (5 mg/mL in PBS) is added to each well and incubated for 4 h, then MTT solution is removed from the wells by aspiration. After careful removal of the medium, 0.1 mL of DMSO is added to each well, and the plate is shaken for 15 min. The data of 7 d are fed into the computer and the growth curve is drawn. The growth inhibition rate (IR) is calculated.|
|Animal Admin||Mice Sixty healthy Kunming mice (26±2 g) are randomly assigned into two groups: a control group (n=15) and an ADR group (n=45). The ADR group is divided into three subgroups: ADR only without Apigenin (ADR, n=15), low-dose Apigenin (125 mg/kg/day, n=15), and high-dose Apigenin (250 mg/kg/day, n=15). All Apigenin-treated groups are treated daily via gastric gavage for seventeen days with a 125 or 250 mg/kg/day dose. ADR (3 mg/kg/day) is injected intraperitoneally into animals at an interval of 48 h (in total, eight times at a cumulative dose of 24 mg/kg). The mice in the control group receive injections of 0.9% sterile saline. On the 17th day after the first treatment, the mice are sacrificed, and blood samples are collected. A number of hearts are fixed with 2.5% glutaraldehyde fixative for electron microscopy analysis, and the others are stored at -80°C for western blot analysis.|
