The anticancer phytochemical rocaglamide inhibits Rho GTPase activity and cancer cell migration.

Numai utilizatorii înregistrați pot traduce articole

Chemotherapy is one of the pillars of anti-cancer therapy. Although chemotherapeutics cause regression of the primary tumor, many chemotherapeutics are often shown to induce or accelerate metastasis formation. Moreover, metastatic tumors are largely resistant against chemotherapy. As more than 90%

Molecular mechanisms and anti-cancer aspects of the medicinal phytochemicals rocaglamides (=flavaglines).

Numai utilizatorii înregistrați pot traduce articole

Rocaglamides (= flavaglines) are potent natural anti-cancer phytochemicals that inhibit cancer growth at nanomolar concentrations by the following mechanisms: (1) inhibition of translation initiation via inhibition of phosphorylation of the mRNA cap-binding eukaryotic translation initiation factor

The Strong Inhibitory Effect of Combining Anti-Cancer Drugs AT406 and Rocaglamide with Blue LED Irradiation on Colorectal Cancer Cells.

Numai utilizatorii înregistrați pot traduce articole

There is still no satisfying method to treat colorectal cancer (CRC) currently. Inspired by cocktail therapy, the combination of 465 nm blue LED irradiation and two multi-target anticancer agents AT406 and Rocaglamide has been investigated for a revolutionary way to treat colorectal cancer cells in

PINK1/Parkin-Mediated Mitophagy Regulation by Reactive Oxygen Species Alleviates Rocaglamide A-Induced Apoptosis in Pancreatic Cancer Cells.

Numai utilizatorii înregistrați pot traduce articole

Pancreatic cancer (PC) is one of the most lethal diseases, and effective treatment of PC patients remains an enormous challenge. Rocaglamide A (Roc-A), a bioactive molecule extracted from the plant Aglaia elliptifolia, has aroused considerable attention as a therapeutic choice for numerous

Rocaglamide overcomes tumor necrosis factor-related apoptosis-inducing ligand resistance in hepatocellular carcinoma cells by attenuating the inhibition of caspase-8 through cellular FLICE-like-inhibitory protein downregulation.

The enhancement of apoptosis is a therapeutic strategy used in the treatment of cancer. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a promising antitumor agent. However, hepatocellular carcinoma (HCC) cells exhibit marked resistance to the induction of cell death by TRAIL. The

Rocaglamide and silvestrol: a long story from anti-tumor to anti-coronavirus compounds

Numai utilizatorii înregistrați pot traduce articole

Covering: up to the beginning of 2020Many natural substances have been transformed again and again with regard to their pharmaceutical-medical potential, including new members of a growing class of natural products, the flavaglines. Important representatives are rocaglamide and silvestrol, isolated

The natural anticancer compound rocaglamide selectively inhibits the G1-S-phase transition in cancer cells through the ATM/ATR-mediated Chk1/2 cell cycle checkpoints.

Targeting the cancer cell cycle machinery is an important strategy for cancer treatment. Cdc25A is an essential regulator of cycle progression and checkpoint response. Over-expression of Cdc25A occurs often in human cancers. In this study, we show that Rocaglamide-A (Roc-A), a natural anticancer

"Prohibitin"g CRAF/MAPK activation with rocaglamides.

Numai utilizatorii înregistrați pot traduce articole

Interaction with prohibitin (PHB) is required for full activation of CRAF kinase, the central member of the highly conserved RAS-CRAF-MAPK pathway. In this issue of Chemistry & Biology, Polier et al. show that the natural anti-tumor compounds rocaglamides target the CRAF-PHB interaction to disrupt

Rocaglamide and a XIAP inhibitor cooperatively sensitize TRAIL-mediated apoptosis in Hodgkin's lymphomas.

Numai utilizatorii înregistrați pot traduce articole

Although most of the patients with Hodgkin's lymphoma (HL) can be cured by the current regimen of high-dose multiagent chemotherapy, the treatment causes high risks of later toxicities including secondary malignancies. Therefore, new rational strategies are needed for HL treatment. Tumor necrosis

The traditional Chinese medical compound Rocaglamide protects nonmalignant primary cells from DNA damage-induced toxicity by inhibition of p53 expression.

Numai utilizatorii înregistrați pot traduce articole

One of the main obstacles of conventional anticancer therapy is the toxicity of chemotherapeutics to normal tissues. So far, clinical approaches that aim to specifically reduce chemotherapy-mediated toxicities are rare. Recently, a number of studies have demonstrated that herbal extracts derived

Apoptotic Effect of Wortmannolone on Cancer Cells through Potent ROS Induction.

Numai utilizatorii înregistrați pot traduce articole

Nuclear factor κappa-B inhibitors isolated from natural sources that induce apoptosis are promising new agents with anticancer properties. Wortmannin and wortmannolone were isolated from endophytic fungus (Penicillum polonicum) and showed NF-κB inhibitory effects with inhibitory concentration (IC50)

Panbinostat decreases cFLIP and enhances killing of cancer cells by immunotoxin LMB-100 by stimulating the extrinsic apoptotic pathway.

Numai utilizatorii înregistrați pot traduce articole

LMB-100 (RG7787) is a recombinant immunotoxin, which kills mesothelin-expressing cancer cells and now being evaluated in phase 1 trials. To enhance the anti-tumor activity of LMB-100, we have searched for agents, already approved for cancer therapy, that can be combined with LMB-100 to increase its

Progress in the total synthesis of rocaglamide.

Numai utilizatorii înregistrați pot traduce articole

The first cyclopenta[b]benzofuran derivative, rocaglamide, from Aglaia elliptifolia, was found to exhibit considerable insecticidal activities and excellent potential as a therapeutic agent candidate in cancer chemotherapy; the genus Aglaia has been subjected to further investigation. Both the

Rocaglamide sensitizes leukemic T cells to activation-induced cell death by differential regulation of CD95L and c-FLIP expression.

Numai utilizatorii înregistrați pot traduce articole

Drugs with tumor selectivity may have an important benefit in chemotherapies. We have previously shown that Rocaglamide(s), derived from the medicinal plant Aglaia, kills various leukemic cells through the mitochondrial apoptosis pathway with only minor toxicities to normal lymphocytes. Here, we

Rocaglamide breaks TRAIL resistance in HTLV-1-associated adult T-cell leukemia/lymphoma by translational suppression of c-FLIP expression.

Numai utilizatorii înregistrați pot traduce articole

The human T-cell leukemia virus type-1 (HTLV-1)-associated adult T-cell leukemia/lymphoma (ATL) is incurable by currently known therapies. ATL samples and cell lines derived from ATL patients show restricted sensitivity to tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and CD95
