Amphotericin B(AMB,兩性霉素B,AbMole,M5415)是一種大環(huán)多烯類抗生素,其能夠與細(xì)胞膜中的特定甾醇結(jié)合,導(dǎo)致膜通透性改變、離子泄漏,最終引發(fā)細(xì)胞功能紊亂[1]。在抗菌方面,Amphotericin B通過上述結(jié)合,破壞真菌膜完整性并發(fā)揮抗真菌作用[2]。此外,
Amphotericin B(AMB,兩性霉素B,AbMole,M5415)在HT-29人結(jié)腸腺癌細(xì)胞和正常結(jié)腸上皮細(xì)胞中能通過氧化損傷途徑影響細(xì)胞活性[3]。此外,在NK細(xì)胞系和原代NK細(xì)胞的研究中發(fā)現(xiàn),Amphotericin B能增強(qiáng)效應(yīng)細(xì)胞與靶細(xì)胞的結(jié)合,從而提升NK細(xì)胞的殺傷能力[4]。在動(dòng)物模型研究中,Amphotericin B(CAS No.:1397-89-3)展現(xiàn)出多方面的應(yīng)用價(jià)值。例如在兔肺感染模型中,Amphotericin B有效抑制了真菌感染,且避免了傳統(tǒng)抑制劑的副作用[5]。
