Autophagy inducer 3 has autophagy induced activity. Autophagy inducer 3 possesses robust autophagic cell death in diverse cancer cells sparing normal counterpart. Autophagy inducer 3 induces lethal autophagy by formation of characteristic autophagic vacuoles, LC3 puncta formation, upregulation of signature autophagy markers like Beclin and Atg family proteins[1].

IC50 & Target


(In Vitro)

Autophagy inducer 3 (compound 26b) (10 μM; 48 hours) effectively inhibits cell growth in diverse breast, lung and colon cancer cell lines[1].
Autophagy inducer 3 (0-10 μM; 48 hours) exhibits potent antiproliferative activity in COLO-205, LOVO, HT-29, DLD-1, SW48 and SW-620 with IC50s of 2.03 μM, 3.33 μM, 4.15 μM, 4.46 μM, 3.14 μM, 1.86 μM, respectively; and shows low cytotoxicity in normal human colon fibroblast CCD-18Co with IC50 over 10 μM[1].
Autophagy inducer 3 (7.5 μM; 18 hours) promotes non apoptotic cell death in DLD-1 cells by cellular granularity through vacuole formation and increase Annexin-V positive cells as well as PARP cleavage; and robustly induces the expression of classical autophagy markers like Beclin-1, Atg3, Atg5 and Atg7[1].
