apoptosis-inducing chemotherapy drugs. Another mode of action to kill these apoptosis-defective cells is essential and autophagy, a dynamic process that degrades cytoplasmic contents for cellular maintenance, has been considered as one of the alternate routes. A small molecule inducer of autophagy, autophagonizer was reported to induce cell death through a novel process that is independent of extrinsic
一些癌细胞对细胞凋亡具有抵抗力,使其对诱导细胞凋亡的化疗药物无反应。杀死这些凋亡缺陷细胞的另一种作用方式是必不可少的,自噬是一种降解细胞质含量以维持细胞的动态过程,被认为是另一种途径。据报道,自噬的小分子诱导剂,自噬剂通过一种新的过程诱导细胞死亡,该过程独立于外在凋亡和自噬的正常信号通路。在这里,我们描述了自噬剂的有效合成程序。新合成的自噬剂(DK-1-49)导致自噬相关LC3-II的积累,并增加了自噬体和酸性液泡的水平。此外,自噬细胞死亡不仅在人类癌细胞中而且在Bax / Bak双敲除细胞中均抑制了细胞活力。这些发现表明,内在性细胞凋亡也不参与自噬剂诱导细胞死亡,这表明自噬剂是抗凋亡诱导化疗的癌细胞抗癌治疗的有前途的候选者。
