ROCAGLAMIDE

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 IC₅₀ 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.

The Uses of ROCAGLAMIDE

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.

What are the applications of Application

Rocaglamide is an immunosuppressant tetrahydrobenzofuran compound and an inhibitor of NFκB activity.

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.
