How to use

In Vitro:

Manzamine A increases acidity in pancreatic cancer cells and non-malignant Vero cells. manzamine A is a potential inhibitor of autophagy by preventing autophagosome turnover. Manzamine A (10 µM; 2 hours; AsPC-1 cells) clearly induced an accumulation of p62 confirming an inhibition of autophagosome turnover. Manzamine A represents an important lead structure for the development of novel antimalarial chemotherapies.
