E. coli CD-expressing genetically modified neural stem cells

Genetically-modified neural stem cells (NSCs) transfected with the Escherichia coli (E. coli) suicidal gene cytosine deaminase (CD), with potential antineoplastic adjuvant activity. Upon intracerebral injection, E. coli CD-expressing genetically modified NSCs express the E. coli cytosine deaminase, an enzyme that catalyzes the intracellular conversion of the nontoxic prodrug 5-fluorocytosine (5-FC) into the cytotoxic 5-fluorouracil (5-FU). Co-administration of this agent with 5-FC and upon local activation of 5-FU in the brain tumor, 5-FU disrupts DNA synthesis in tumor cells thereby impeding cellular proliferation with minimal systemic exposure and toxicity.

E-101 solution

An oxidant-generating coupled-enzyme system-based, topical solution comprised of two enzymes, Aspergillus niger-derived glucose oxidase (GO) and porcine myeloperoxidase (p-MPO), as well as glucose, sodium chloride and stabilizing amino acids, with potential broad-spectrum microbicidal activity. Following direct administration of E-101 solution into the surgical incisional wound via microspray, the enzyme GO converts oxygen into hydrogen peroxide (H2O2). In turn, p-MPO catalyzes the reaction of H2O2 with hypochlorous acid (HOCl), which is formed through oxidation of the chloride ion, to generate singlet oxygen (O2*). As p-MPO binds to microorganisms, O2* is able to exert direct oxidative damage to microorganisms, resulting in potent antimicrobial activity. E-101 may act as an anti-bactericidal agent against a variety of microorganisms, including multidrug-resistant strains. This may prevent infection at the surgical site.

E2F1 pathway activator ARQ 171

A second-generation E2F1 pathway activator with potential antineoplastic activity.

EED inhibitor MAK683

An inhibitor of embryonic ectoderm development protein (EED) and allosteric inhibitor of polycomb repressive complex 2 (PRC2), with potential antineoplastic activity. Upon administration, MAK683 selectively binds to the domain of EED that interacts with trimethylated lysine 27 on histone 3 (H3K27me3), which leads to a conformational change in the EED H3K27me3-binding pocket and prevents the interaction of EED with the histone methyltransferase enhancer zeste homolog 2 (EZH2). Disruption of the EED-EZH2 protein-protein interaction (PPI) results in a loss of H3K27me3-stimulated PRC2 activity and prevents H3K27 trimethylation. This decrease in histone methylation alters gene expression patterns associated with cancer pathways and results in decreased tumor cell proliferation in EZH2-mutated and PRC2-dependent cancer cells. PRC2, a histone H3 lysine 27 methyltransferase and multi-protein complex comprised of EZH2, EED and suppressor of zeste 12 (SUZ12), plays a key role in gene regulation, especially during embryonic development. EZH2, the catalytic subunit of PRC2, is overexpressed or mutated in a variety of cancer cells.

Elesclomol induces oxidative stress, creating high levels of reactive oxygen species (ROS), such as hydrogen peroxide, in both cancer cells and normal cells. Because tumor cells have elevated levels of ROS compared to normal cells, the increase in oxidative stress beyond baseline levels elevates ROS beyond sustainable levels, exhausting tumor cell antioxidant capacity, which may result in the induction of the mitochondrial apoptosis pathway. Normal cells are spared because the increase in the level of oxidative stress induced by this agent is below the threshold at which apoptosis is induced.

enadenotucirev

A complex, replication-selective, E1B and partial E3 gene deleted, adenovirus type 11p (Ad11p)/Ad3 chimeric oncolytic virus with potential antineoplastic activity. Upon intralesional injection of enadenotucirev, the adenovirus selectively and rapidly replicates in cancer cells; however, it is unable to replicate in normal, healthy cells. This induces a selective adenovirus-mediated cytotoxicity in cancer cells, which leads to cancer cell lysis. Following the lysis of infected cells, the replicated virus is released and can infect adjacent cells, which both induces further tumor cell oncolysis and may activate the immune system to kill the infected tumor cells. The E1B protein causes p53 inactivation in host cells, which promotes viral replication. Deletion of E1B prevents replication in normal, healthy cells that express wild-type p53. The mutation and subsequent inactivation of p53 in cancer cells enables the E1B-deleted adenovirus to selectively replicate in cancer cells. Partial deletion of the E3 gene, which encodes the adenovirus death protein, enhances the safety profile of the administered adenovirus. Check for active clinical trials using this agent.

enalapril maleate

The maleate salt form of enalapril, a dicarbocyl-containing peptide and angiotensin-converting enzyme (ACE) inhibitor with antihypertensive activity. As a prodrug, enalapril is converted by de-esterification into its active form enalaprilat. Enalaprilat competitively binds to and inhibits ACE, thereby blocking the conversion of angiotensin I to angiotensin II. This prevents the potent vasoconstrictive actions of angiotensin II and results in vasodilation. Enalapril also decreases angiotensin II-induced aldosterone secretion by the adrenal cortex, which leads to an increase in sodium excretion and subsequently increases water outflow. Check for active clinical trials using this agent. (NCI Thesaurus)

ERa36 modulator icaritin

A metabolite of A metabolite of icariin, a principal flavonoid glycoside in Herba Epimedii (a traditional Chinese medicine herb used in treating osteoporosis) with potential antineoplastic activity. ERa36 modulator icaritin selectively binds to a novel variant of estrogen receptor alpha, a36, and mediates a membrane-initiated "nongenomic" signaling pathway, which is linked to activated signaling pathways like the MAPK/ERK and the PI3K/Akt pathways. This agent induces cell cycle arrest at G1, or G2/M arrest depending upon the dose. Consistently with G1 arrest, icaritin increases protein expressions of pRb, p27(Kip1) and p16(Ink4a), while decreasing phosphorylated pRb, Cyclin D1 and CDK4. Forty percent of ER-negative breast cancer tumors express high levels of ERa36, and this subset of patients is less likely to benefit from tamoxifen treatment compared with those with ERa66-positive/ERa36-negative tumors.

Ery-Tab

(Other name for: erythromycin)

erythrocyte-encapsulated L-asparaginase suspension

A suspension of erythrocytes encapsulating L-asparaginase with potential antineoplastic activity. Upon administration of erythrocyte-encapsulated L-asparaginase suspension, L-asparagine is hydrolyzed to L-aspartic acid and ammonia in plasma, thereby depleting tumor cells of asparagine.

estradiol/norethindrone acetate tablet

An orally bioavailable tablet formulation containing the semisynthetic estrogen estradiol in combination with the acetate form of the synthetic progestin norethindrone, with estrogenic and progesteronic activities. Estradiol binds to and activates intracellular estrogen receptors found in the reproductive tract and other estrogen-responsive tissues. The activated complex enters the nucleus, binds to the estrogen response elements on DNA, and activates the transcription of genes involved in the maintenance of the female reproductive system and secondary sexual characteristics, the proliferation of the endometrium, and bone metabolism. Norethindrone binds to the intracellular progesterone receptors in the reproductive system and the activated ligand/receptor complex interacts with specific DNA response elements, resulting in an alteration in protein synthesis; inhibition of luteinizing hormone (LH) and follicle stimulating hormone (FSH) release; inhibition of ovulation; an increase in cervical mucus production; and induction of the secretory phase of the endometrial cycle. Administration of estradiol/norethindrone acetate may abrogate vasomotor symptoms associated with menopause and prevent bone loss associated with the postmenopause.
