| Hazard Information | Back Directory | [Description]
Spautin-1 (1262888-28-7) is a specific and potent autophagy inhibitor. Spautin-1 promotes the degradation of Vps34 PI3 kinase complexes by inhibiting two ubiquitin-specific proteases USP10 and USP13 which target the Beclin-1 subunit of Vps34 complexes.1?Deranges dengue virion maturation.2?Spautin-1 inhibits autophagy in a Beclin-1 independent manner in primary epithelial ovarian cancer cells.3?Selectively induces cell death of mutant p53-expressing cancer cell lines under confluency.4?Cell permeable. | [Uses]
Spautin-1 has been used as an autophagy inhibitor:
- to study its effects on vascular, glial, and neuronal alterations in the oxygen-induced retinopathy mouse model
- to evaluate its pre-treatment effect on the response of canine osteosarcoma cells to doxorubicin
- to study its effects on the production of interleukin (IL)-6 by oxidatively stressed dendritic cells (OS-DCs) in Luminex assay
| [Uses]
Spautin-1 is a potent pharmacological autophagy inhibitor that promotes UVB-induced tumorigenesis. It is also a small-molecule drug that modulate autophagic pathways in different types of cancer. | [Biochem/physiol Actions]
Spautin-1 inhibits the activity of two ubiquitin-specific peptidases, USP10 and USP13, causing an increase in proteasomal degradation of class III PI3 kinase complexes, which have been shown to regulate autophagy. | [in vitro]
spautin-1 promotes the degradation of vps34 pi3 kinase complexes via inhibiting two ubiquitinspecific peptidases, usp10 and usp13, that target the beclin1 subunit of vps34 complexes. spautin-1 had no effect on the growth and survival of bcap-37 cells under normal culture conditions but dramatically enhanced cell death in glucose-free media. under glucose-free conditions, western blotting for lc3 further confirmed that autophagy was induced, which was inhibited by spautin-1. similar results were obtained with mcf-7 and bt549 cells. therefore, spautin-1 can sensitize tumor cells to apoptosis under nutritional deprived conditions [1]. | [IC 50]
