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[1].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[1].CA-5f (20 μM) neither impairs the hydrolytic function nor the quantity of lysosomes[1].CA-5f (20 μM, 96 hours) inhibits the growth of A549 cells, and less cytotoxic to normal HUVECs[1].|| Cell Viability Assay[1]||Cell Line:|A549, HUVECs|Concentration:|20 μM|Incubation Time:|96 hours|Result:|Exhibited more cytotoxicity against A549 cells compared with normal HUVECs.|| Western Blot Analysis[1]||Cell Line:|A549 cells and HUVECs|Concentration:|0-40 μM|Incubation Time:|6 hours|Result:|Elevated LC3B-II (a marker to monitor autophagy) and SQSTM1 protein levels in a concentration- and time-dependent manner.

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[1]. CA-5f (40 mg/kg, i.p.) suppresses autophagic flux and induces apoptosis in nude mice bearing A549 lung cancer cells[1].|| Animal Model:|Nude mice bearing A549 lung cancer cells[1]|Dosage:|40 mg/kg|Administration:|Injected via caudal vein, every 2 days for up to 30 days|Result:|Significantly suppressed tumor volume and weight in mice, increased the number of apoptotic cells in mice.
