dimethyl fumarate

An orally bioavailable methyl ester of fumaric acid and activator of nuclear factor erythroid 2 [NF-E2]-related factor 2 (Nrf2, Nfe2l2), with potential neuroprotective, immunomodulating and radiosensitizing activities. Although the exact mechanism of action through which dimethyl fumarate exerts its neuroprotective and immunomodulatory effects have yet to be fully understood, upon oral administration, dimethyl fumarate is converted into its active metabolite monomethyl fumarate (MMF) and MMF binds to Nrf2. Subsequently, Nrf2 translocates to the nucleus and binds to the antioxidant response element (ARE). This induces the expression of a number of cytoprotective genes, including NAD(P)H quinone oxidoreductase 1 (NQO1), sulfiredoxin 1 (Srxn1), heme oxygenase-1 (HO1, HMOX1), superoxide dismutase 1 (SOD1), gamma-glutamylcysteine synthetase (gamma-GCS), thioredoxin reductase-1 (TXNRD1), glutathione S-transferase (GST), glutamate-cysteine ligase catalytic subunit (Gclc) and glutamate-cysteine ligase regulatory subunit (Gclm); this also increases the synthesis of the antioxidant glutathione (GSH). The intraneuronal synthesis of GSH may protect neuronal cells from damage due to oxidative stress. Dimethyl fumarate also appears to inhibit the nuclear factor-kappa B (NF-kB)-mediated pathway, modulates the production of certain cytokines and induces apoptosis in certain T-cell subsets. Its radiosensitizing activity is due to this agent's ability to bind to and sequester intracellular GSH, thereby depleting intracellular GSH and preventing its anti-oxidative effects. This enhances the cytotoxicity of ionizing radiation in hypoxic cancer cells. Nrf2, a leucine zipper transcription factor, plays a key role in redox homeostasis and cytoprotection against oxidative stress. Check for active clinical trials using this agent. (NCI Thesaurus)

Dioscorea nipponica Makino extract DNE3

An extract of the plant Dioscorea nipponica Makino and inhibitor of both the serine/threonine protein kinase Akt (protein kinase B) and members of the phosphatidylinositol 3-kinase (PI3K) family of lipid kinases, with potential antineoplastic and anti-metastatic activities. Dioscorea nipponica Makino extracted with ethyl acetate (DNE3) binds to and inhibits PI3K and Akt. This inhibits PI3K/Akt-mediated signaling and prevents both growth and survival of PI3K/Akt-overexpressing tumor cells. In addition, DNE3 increases the expression of tissue inhibitor of metalloproteinase-2 (TIMP-2), inhibits the secretion of matrix metalloproteinases (MMPs), primarily MMP-2 and MMP-9, and inhibits the serine protease urokinase (urokinase-type plasminogen activator; u-PA). This inhibits tumor cell invasion, migration, motility, and adhesion. This agent also inhibits the activation of both cAMP response element-binding (CREB) and activating protein-1 (AP-1), and increases the expression of IkappaB (IkB), which inhibits the activation of nuclear factor-kappa B (NF-kB).

diphtheria toxin fragment-interleukin-2 fusion protein E7777

A cytotoxic recombinant fusion protein consisting of the human cytokine interleukin-2 (IL-2) fused to diphtheria toxin fragments A and B, containing both the catalytic and translocation domains, with potential antineoplastic activity. Upon administration, the IL-2 moiety of diphtheria toxin fragment-IL-2 fusion protein E7777 binds to IL-2 receptors. After internalization by IL-2 receptor-expressing cells via endocytosis, the agent is proteolytically cleaved. This releases the catalytic domain of the toxin moiety, which catalyzes the transfer of the ADP-ribose moiety of NAD to a diphthamide residue of elongation factor 2 (EF-2). This covalent modification inactivates EF-2 and disrupts polypeptide chain elongation, resulting in an inhibition of translation and cell death.

disulfiram

An orally bioavailable carbamoyl derivative and a proteasome inhibitor that is used in the treatment of alcoholism, with potential antineoplastic and chemosensitizing activities. Disulfiram (DSF) may help to treat alcoholism by irreversibly binding to and inhibiting acetaldehyde dehydrogenase, an enzyme that oxidizes the ethanol metabolite acetaldehyde into acetic acid. Inhibition of acetaldehyde dehydrogenase leads to an accumulation of acetaldehyde and produces a variety of very unpleasant symptoms, which together are referred to as the disulfiram-ethanol reaction (DER). In addition, DSF has a strong ability to chelate metals and its antineoplastic activity is highly dependent upon binding to copper (Cu), a metal that selectively accumulates in cancer cells. DSF/Cu generates reactive oxygen species (ROS) and inhibits proteasome activity, leading to an accumulation of ubiquitinated proteins; both of these processes result in induction of apoptosis. Also, DSF/Cu inhibits various cancer-specific pathways, which leads to inhibition of tumor cell growth. Check for active clinical trials using this agent. (NCI Thesaurus)
