產(chǎn)品簡介:
尼日利亞菌素(Nigericin),來源于吸水鏈霉菌(Streptomyces hygroscopius)代謝產(chǎn)物的一種聚醚抗生素,常常用作鉀離子載體,促進(jìn)穿透生物膜的K+/H+交換,作用機(jī)制類似于纈氨霉素(貨號:NBS7624-10mg),其攜帶單價陽離子跨膜的特異性為:K+>Rb+>Cs+>>Na+。還可用作Pb2+離子載體,但對其他二價陽離子未表現(xiàn)出載運活性。作為一種有效的研究工具,能夠激活ATPase酶活性,并且破壞線粒體膜電位。通過加強(qiáng)離子的膜擴(kuò)散能力來殺死細(xì)菌。類似于ATP,尼日利亞菌素通過縫隙連接蛋白1(Pannexin-1)依賴性的方式,刺激胞內(nèi)K+外流,誘導(dǎo)NLRP3炎癥小體組裝,凋亡相關(guān)蛋白Caspase-1成熟,進(jìn)而刺激IL-1β的加工和釋放。
本品以尼日利亞菌素的鈉鹽形式提供,CAS NO. 28643-80-3,普遍用來研究各種生物系統(tǒng)中膜電位變化產(chǎn)生的生理后果。也常用作NLRP3炎癥小體激活劑,研究炎癥小體應(yīng)對不同刺激物和危險信號的應(yīng)答方式,從而開發(fā)靶向多種免疫疾病的治療手段。

體外研究:
細(xì)胞類型(Cell type):Four strains of lactobacilli and E. hirae JCM 8729T
實驗方法(Assay):To evaluate the effect of ΔpH on alkali tolerance, growth experiments using four strains of lactobacilli and E. hirae JCM 8729T were conducted in the presence or absence of nigericin at pH values between 6.5 and 9.0. Nigericin in ethanol solution was added at a final concentration of 7 μM. Control cultures received 0.1% (vol/vol) ethanol. Specific growth rates were calculated during the exponential growth phase as described above.

體內(nèi)研究:
動物模型(Animal Model):Nude mice injected with S19 cells
實驗方法(Assay):Mice are randomly divided into four groups with six animals each (control, DDP, Nigericin and DDP combined with Nigericin). DDP (2.5 mg/kg) is injected intraperitoneally for five continuous days and nigericin (4 mg/kg) is administrated intraperitoneally every two days.
給藥途徑(Administration):Intraperitoneal (i.p.) injection
