General description

A cell-permeable methylanthranilate analog that reversibly inhibits vesicular traffic from ER to Golgi in mammalian cells (IC50 = 20 µM in BSC1 cells) by inducing tubulation and collapsing of the Golgi membrane and redirecting the traffic back to ER. Acts as a potent and selective modifier of Golgi ARF1 GTPase activity. Unlike another membrane traffic inhibitor Brefeldin A (BFA; Cat. No. 203729), its effect seems to be limited to Golgi, as no effect can be detected on endocytic organelles, such as endosomes and TGN (trans-Golgi network). Its inhibitory mechanism and target(s) appear to be quite different from those of BFA and thus serves as a valuable alternative that complements BFA in membrane traffic studies.

Pancreatic ductal adenocarcinoma (PDAC) tumours carry multiple gene mutations and respond poorly to treatments. There is currently an unmet need for drug carriers that can deliver multiple gene cargoes to target high solid tumour burden like PDAC. Here, we report
