Description
Rocaglamide is an anti-
inflammatory, insecticidal, and anticancer tetrahydrobenzofuran isolated from
Aglaia species. It has been shown to inhibit both TNF-
α and the activation of NF-
κB in Jurkat T cells with IC
50 values in the nanomolar range. At 25 nM, rocaglamide induces apoptosis in various human leukemia cell lines, activating p38 MAPK/JNK and suppressing ERK. Rocaglamide also reduces IFN-
γ, TNF-
α, IL-
2, and IL-
4 production in peripheral blood T cells at a concentration of 50 nM. Furthermore, rocaglamide can inhibit the T cell expression of the immune response transcription factor, nuclear factor of activated T cells.
Uses
Rocaglamide is derived from a Chinese medicinal plant Aglaia. Rocaglamide induces apoptosis in various human leukemia cell lines and in acute lymphoblastic leukemia, chronic myeloid leukemia and acute myeloid leukemia cells freshly isolated from patients.
Definition
ChEBI: An organic heterotricyclic compound that is 2,3,3a,8b-tetrahydro-1H-benzo[b]cyclopenta[d]furan substituted by hydroxy groups at positions 1 and 8b, methoxy groups at positions 6 and 8, a 4-methoxyphenyl group at
position 3a, a phenyl group at position 3 and a N,N-dimethylcarbamoyl group at position 1. Isolated from Aglaia odorata and Aglaia duperreana, it exhibits antineoplastic activity.
General Description
Rocaglamide is known to be derived from tetrahydro benzofuran and is also an active chemical compound of
Aglaia plants.
Biochem/physiol Actions
Rocaglamide is a potent anticancer agent isolated from the genus Aglaia. Rocaglamides inhibit protein synthesis without affecting DNA or RNA synthesis. Recent study shows that Rocaglamide binds to prohibitin (PHB) 1 and 2, which prevents interaction between PHB and CRaf and inhibits CRaf activation and subsequently CRaf-MEK-ERK signaling. Also, Rocaglamide is an immunosuppressant that inhibits activation of NF-kB and NF-AT.
