Amphotericin B(AMB,两性霉素B)是一种大环多烯类抗生素,其能够与细胞膜中的特定甾醇结合,导致膜通透性改变、离子泄漏,最终引发细胞功能紊乱[1]。在抗菌方面,Amphotericin B通过上述结合,破坏真菌膜完整性并发挥抗真菌作用[2]。此外,Amphotericin B(AbMole,M5415)在HT-29人结肠腺癌细胞和正常结肠上皮细胞中能通过氧化损伤途径影响细胞活性[3]。此外,在NK细胞系和原代NK细胞的研究中发现,Amphotericin B能增强效应细胞与靶细胞的结合,从而提升NK细胞的杀伤能力[4]。在动物模型研究中,Amphotericin B(CAS No.:1397-89-3)展现出多方面的应用价值。例如在兔肺感染模型中,Amphotericin B有效抑制了真菌感染,且避免了传统抑制剂的副作用[5]。

德国汉堡埃彭多夫大学、德国罗斯托克大学的科研人员在该文章中使用了AbMole的Amphotericin B(两性霉素B,AbMole,M5415)科研人员在上述研究中系统探讨了PI3K/AKT/mTOR信号通路在结直肠癌中的作用。研究发现,联合使用AKT抑制剂MK2206和mTOR抑制剂RAD001(Everolimus)对结直肠癌(CRC)细胞系和PDO肿瘤类器官具有显著的协同抑制作用。并且体内实验进一步证实联合处理能有效抑制结直肠癌异种移植瘤的生长。Amphotericin B作为抗真菌药物,在组织样本处理和细胞培养过程中用于防止真菌污染,保护样本的完整性和活性。
