CA-5f is a potent late-stage macroautophagy/autophagy inhibitor via inhibiting autophagosome-lysosome fusion. CA-5f increases LC3B-II (a marker to monitor autophagy) and SQSTM1 protein, and also increases ROS production. Anti-tumor activity.

How to use

In Vitro:

CA-5f (0-40 μM, 6 hour) concentration- and time-dependently elevates the level of LC3B-II (a marker to monitor autophagy) and SQSTM1 protein both in A549 cells and HUVECs. CA-5f (20 μM, 6 hours) inhibits the degradation of autophagosomes when treated alone or in combination Bafilomycin A1 (100 nM) or Chloroquine (30 μM) in A549 cells and HUVECs. CA-5f (20 μM) neither impairs the hydrolytic function nor the quantity of lysosomes. CA-5f (20 μM, 96 hours) inhibits the growth of A549 cells, and less cytotoxic to normal HUVECs.

In Vivo:

CA-5f (40 mg/kg, i.p., every 2 days for up to 30 days) is well tolerated, and potently inhibits the growth of tumor in nude mice bearing A549 lung cancer cells. CA-5f (40 mg/kg, i.p.) suppresses autophagic flux and induces apoptosis in nude mice bearing A549 lung cancer cells.
