名稱 | (E)-Flavokawain A |
描述 | (E)-Flavokawain A, a novel chalcone from kava extract, induces apoptosis in bladder cancer cells by involvement of Bax protein-dependent and mitochondria-dependent apoptotic pathway and suppresses tumor growth in mice. |
激酶實驗 | Probe-based assays with rat liver microsome system were used to characterize the inhibitory effects of FLAVOKAVAIN A(P). Molecular docking study was performed to further explore the binding site of FLAVOKAVAIN A(P) on CYP450 isoforms. Chemical inhibition experiments using specific inhibitors (a-naphthoflavone, quinidine, sulfamethoxazde, ketoconazole, omeprazole) were performed to clarify the individual CYP450 isoform that are responsible for the metabolism of FLAVOKAVAIN A(P)[1]. |
動物實驗 | Flavokawain A was formulated in 10% grain alcohol in 0.9% saline and given by gavage. EJ bladder tumor cells were concentrated to 2 × 10^6 per 200 μL and injected s.c. into the right flank of each mouse. Next day, the mice were randomly divided and pair matched into treatment and control groups of 18 mice each, and daily dosing was begun with vehicle or 50 mg/kg flavokawain A. Because there were no in vivo data regarding flavokawain A before this study, the dose of flavokawain A (50 mg/kg/d) was used according to 1:60 of 3,000 mg/kg, a LD50 dose for a similar chemical structure compound, isoliquiritigenin . Body weight, diet, and water consumption were recorded thrice weekly throughout the study. Once xenografts started growing, their sizes were measured every other day. The tumor volume was calculated by the formula: 0.5236 L1(L2)^2, where L1 is the long axis and L2 is the short axis of the tumor. At the end of experiment, tumors were excised, weighed, blood collected, and stored at ?80°C until additional analysis[2]. |
體外活性 | Flavokawain A 對CYP1A2、CYP2D1、CYP2C6和CYP3A2活性表現(xiàn)出顯著抑制作用,其IC50值分別為102.23、20.39、69.95、60.22μmol/L。抑制模式分別為競爭性抑制、混合抑制、非競爭性抑制和非競爭性抑制。分子對接研究顯示,F(xiàn)lavokawain A 在CYP450亞型活性位點中的配體結(jié)合構(gòu)象?;瘜W(xué)抑制實驗表明,在酮康唑、磺胺甲噁唑和α-萘黃酮存在下,F(xiàn)lavokawain A的代謝清除率分別降至對照的19.84%、50.38%及67.02%[1]。 |
體內(nèi)活性 | Flavokawain A導(dǎo)致侵襲性膀胱癌細胞系T24的線粒體膜電位顯著下降及細胞色素c釋放到胞質(zhì)中。Flavokawain A的這些效應(yīng)伴隨著Bcl-x(L)的時間依賴性減少、Bcl-x(L)與Bax結(jié)合的減少以及Bax蛋白活性形式的增加。通過使用主要的小鼠胚胎成纖維細胞Bax敲除和野生型細胞以及來源于Ku70的Bax結(jié)合域的Bax抑制肽,至少在部分上,Bax蛋白對Flavokawain A的凋亡效應(yīng)是必需的。此外,F(xiàn)lavokawain A下調(diào)X連鎖凋亡抑制劑和存活蛋白的表達。因為X連鎖凋亡抑制劑和存活蛋白是抵抗凋亡的主要因素,并在膀胱腫瘤中過表達,表明Flavokawain A可能在誘導(dǎo)膀胱腫瘤凋亡方面具有雙重效能。 |
