- Background
Rocaglamide, also referred to as rocaglamide-A, is the eponymous member of a class of anti-cancer phytochemicals known as rocaglamides.1 Rocaglamides are secondary metabolites of the plant genus Aglaia, and extracts of the plant have traditionally been used as a form of insect repellant due to its natural insecticidal properties.9 Reports of Aglaia anti-tumor activity date back as far as 1973, and rocaglamide-A was first isolated in 1982 from the species A. elliptifolia.1 Rocaglamide and a number of its derivatives (e.g. didesmethylrocaglamide) are currently being studied for use as chemotherapeutic agents in the treatment of various leukemias, lymphomas, and carcinomas, as well as adjuvant therapy in the treatment of certain chemotherapy-resistant cancers.7,8,10,3

- Mechanism of action
Rocaglamide’s anti-tumor activity is driven primarily via inhibition of protein synthesis in tumor cells.1 Inhibition of protein synthesis is accomplished via inhibition of prohibitin 1 (PHB1) and prohibitin 2 (PHB2)2 - these proteins are necessary in the proliferation of cancer cells and are implicated in the Ras-mediated CRaf-MEK-ERK signaling pathway responsible for phosphorylating eIF4E, a key factor in the initiation of protein synthesis.2,1 The rocaglamide derivative silvestrol has also been observed to act directly on eIF4A, another translation initiation factor of the eIF4F complex ultimately responsible for initiation of protein synthesis.3
Inhibition of protein synthesis has a number of downstream effects. Many of the proteins that are down-regulated in response to protein synthesis inhibition in tumor cells are short-lived proteins responsible for regulation of the cell cycle, such as Cdc25A.1 Cdc25A is an oncogene that can become overexpressed in certain cancers and lead to unchecked cell growth.4 In addition to inhibiting its synthesis via the mechanism described above, rocaglamide promotes degradation of Cdc25A via activation of the ATM/ATR-Chk1/Chk2 checkpoint pathway5. This pathway is normally activated in response to DNA damage and serves to reduce the expression of proteins responsible for cell cycle progression, thereby inhibiting proliferation of damaged (i.e. tumour) cells. Rocaglamide’s inhibition of protein synthesis also appears to prevent the actions of the transcription factor heat shock factor 1 (HSF1), leading to an increased expression of thioredoxin-interacting protein (TXNIP) which is negatively regulated by HSF1.6 TXNIP is a negative regulator of cell glucose uptake, and its increased expression blocks glucose uptake and consequently impairs the proliferation of malignant cells.6
Rocaglamide also appears to induce apoptosis in tumor cells via activation of the pro-apoptotic proteins p38 and JNK and inhibition of the anti-apoptotic Mcl-1 protein.1 Similarly, it has been studied as an adjuvant in TRAIL-resistant cancers due to its ability to inhibit the synthesis of c-FLIP and IAP/XIAP - these anti-apoptotic proteins can become elevated in certain cancers, preventing the induction of apoptosis and resulting in resistance to TRAIL-based therapies.7,8

- General Function
- Acts as a mediator of transcriptional repression by nuclear hormone receptors via recruitment of histone deacetylases (By similarity). Functions as an estrogen receptor (ER)-selective coregulator that potentiates the inhibitory activities of antiestrogens and represses the activity of estrogens. Competes with NCOA1 for modulation of ER transcriptional activity. Probably involved in regulating mitochondrial respiration activity and in aging.
