Chemical Name: 1,6,7,8,9,11aβ,12,13,14,14αa-Decahydro-1β,13α-dihydroxy-6β-methyl-4H-cyclopent(f)oxacyclotridecin-4-one

Biological Activity

Reversible inhibitor of protein translocation from the endoplasmic reticulum (ER) to the Golgi apparatus. Blocks binding of ADP-ribosylation factor to the Golgi apparatus and inhibits GDP-GTP exchange. Can be used to induce autophagy in mammalian cells. Also enhances CRISPR-mediated homology-directed repair (HDR) efficiency ~2-fold when applied at 100 nM, in human induced pluripotent stem cells (iPSCs).

Technical Data

Soluble to 50 mM in DMSO and to 10 mM in ethanol
>98 %
Desiccate at -20°C
