Coibamide A
Coibamide A, an N-methyl-stabilized cytotoxic depsipeptide, shows potent antiproliferative activity. Coibamide A induces autophagosome accumulation via an mTOR-independent mechanism. Coibamide A induces apoptosis. Coibamide A inhibits VEGFA/VEGFR2 expression and suppresses tumor growth in glioblastoma xenografts.

Coibamide A (0.3-1 nM; 3-60 hours) inhibits proliferation of MDA-MB-231 breast cancer cells[1].
Coibamide A (2.3-230 nM; 3 days) produces concentration- and time-dependent cell death in human U87-MG and SF-295 glioblastoma cells[2].
Coibamide A (10-300 nM; 72 h) induces activation of caspase-3/7 and apoptosis in a cell type-specific manner[2].
Coibamide A (20 nM; 48 h) induces autophagosome accumulation in apoptotic-resistant U87-MG cells[2].

-
Cell Line:MDA-MB-231 breast cancer cells
-
Concentration:0.3, 1 nM
-
Incubation Time:3-60 hours
-
Result:Showed a steady concentration-dependent decrease in proliferative activity relative to vehicle-treated cells
-
Cell Line:U87-MG and SF-295 cells
-
Concentration:2.3 to 230 nM
-
Incubation Time:3 days
-
Result:Induced concentration-dependent cytotoxicity with EC50 values of 28.8 nM and 96.2 nM for U87-MG and SF-295 cells, respectively.
-
Cell Line:U87-MG and SF-295 cells
-
Concentration:10-300 nM
-
Incubation Time:72 h
-
Result:An 89 kDa band corresponding to the caspase 3-cleaved form of PARP1 was readily detected by 48 h indicative of apoptotic cell death in SF-295 cells, whereas only trace levels of this fragment were observed in late, detaching U87-MG cell lysates
-
Cell Line:U87-MG cell
-
Concentration:20 nM
-
Incubation Time:48 h
-
Result:Caused a clear increase in LC3-II expression by 1 h, and this increase in LC3-II expression was generally sustained through 48 h.

-
Animal Model:8-week old female nude athymic mice with U87-MG cells[1]
-
Dosage:300 μg/kg
-
Administration:Intratumoral injections; for the first two days, and then every 48 h afterward for 35 days
-
Result:Remained stable at 200-300 mm3 without significant growth over 4 weeks of treatmen, whereas the tumors of vehicle-treated animals continued to grow at a steady rate consistent with this aggressive cancer cell type
