Vacuolin-1
| 产品介绍 | Vacuolin-1 是一种有效的细胞渗透溶酶体胞吐 (lysosomal exocytosis) 抑制剂。Vacuolin-1 阻断了溶酶体 Ca2+ 依赖性的胞吐作用,在不影响再封闭过程的情况下阻止溶酶体内容物的释放。Vacuolin-1 是一种有效的选择性 PIKfyve 抑制剂,通过损害溶酶体成熟来抑制晚期自噬 (autophagy)。 | ||||||||||||||||

| 生物活性 | Vacuolin-1 is a potent and cell-permeable lysosomal exocytosis inhibitor. Vacuolin-1 blocks the Ca2+-dependent exocytosis of lysosomes and prevents the release of lysosomal content without affecting the process of resealing. vacuolin‐1 is a potent and selective PIKfyve inhibitor and inhibits late‐stage autophagy by impairing lysosomal maturation. | ||||||||||||||||
| 体外研究 |
Vacuolin-1 (1 μM; Pretreatment 1 hour) blocks ionomycin-induced exocytosis of lysosomes but not of enlargeosomes. It results in vacuolation of lysosomes (A) and complete inhibition of the surface expression of Lamp-1. Vacuolin-1 (1 μM; 20-180 min) disrupts the segregation of inner and limiting membranes characteristic of endosomes and lysosomes. Ultrastructural analysis also shows that vacuolin-1 favours fusion of inner and limiting membranes. Vacuolin-1 (5 or 10 μM; 2 hours) blocks the Ca2+-dependent release of β-hexosaminidase from lysosomes. In HeLa cells, ionomycin results in the expected release of 18-20% of lysosomal β-hexosaminidase. But when cells pretreated with vacuolin-1, releases no more β-hexosaminidase compared with cells that are not exposed to ionomycin (4%). 西域 has not independently confirmed the accuracy of these methods. They are for reference only. | ||||||||||||||||
