Summary
Didesmethylrocaglamide, a derivative of Rocaglamide, is a potent eukaryotic initiation factor 4A (eIF4A) inhibitor. Didesmethylrocaglamide has potent growth-inhibitory activity with an IC 50 of 5 nM. Didesmethylrocaglamide suppresses multiple growth-promoting signaling pathways and induces apoptosis in tumor cells. Antitumor activity [1] [2] .
IC50 & Target
Eukaryotic initiation factor 4A (eIF4A) [1]
In Vitro
Didesmethylrocaglamide (5 nM, and 10 nM; 72 hours; MPNST cells) treatment arrests MPNST cells at G2-M, increases the sub-G1 population, induces cleavage of caspases and PARP, and elevates the levels of the DNA-damage response marker γH2A.X, while decreasing the expression of AKT and ERK1/2
[1]
.
Didesmethylrocaglamide inhibits MPNST cell proliferation by inducing cell cycle arrest at G2/M and subsequently, cell death. Didesmethylrocaglamide-treated 697-R cells exhibits IC
50
values is very similar to those of parental 697 cells (4 vs 3nM of IC
50
, respectively)
[1]
.
Didesmethylrocaglamide induces apoptosis in both neurofibromatosis type 1 (NF1)-expressing and NF1-deficient MPNST cells, possibly subsequent to the activation of the DNA damage response. Didesmethylrocaglamide-treated sarcoma cells show decreased levels of multiple oncogenic kinases, including insulin-like growth factor-1 receptor
[1]
