etodolac

A pyranocarboxylic acid and non-steroidal anti-inflammatory drug (NSAID) with antipyretic and analgesic activities. Etodolac inhibits the activity of cyclooxygenase I and II, thereby preventing the formation of prostaglandin which is involved in the induction of pain, fever, and inflammation. It also inhibits platelet aggregation by blocking platelet cyclooxygenase and the subsequent formation of thromboxane A2. Check for or using this agent. ()

Etopophos

(Other name for: etoposide phosphate)

etoposide

A semisynthetic derivative of podophyllotoxin, a substance extracted from the mandrake root Podophyllum peltatum. Possessing potent antineoplastic properties, etoposide binds to and inhibits topoisomerase II and its function in ligating cleaved DNA molecules, resulting in the accumulation of single- or double-strand DNA breaks, the inhibition of DNA replication and transcription, and apoptotic cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle. Check for or using this agent. ()

etoposide phosphate

A phosphate salt of a semisynthetic derivative of podophyllotoxin. Etoposide binds to the enzyme topoisomerase II, inducing double-strand DNA breaks, inhibiting DNA repair, and resulting in decreased DNA synthesis and tumor cell proliferation. Cells in the S and G2 phases of the cell cycle are most sensitive to this agent. Check for or using this agent. ()

etoricoxib

A synthetic, nonsteroidal anti-inflammatory drug (NSAID) with antipyretic, analgesic ,and potential antineoplastic properties. Etoricoxib specifically binds to and inhibits the enzyme cyclooxygenase-2 (COX-2), resulting in inhibition of the conversion of arachidonic acid into prostaglandins. Inhibition of COX-2 may induce apoptosis and inhibit tumor cell proliferation and angiogenesis. Check for or using this agent. ()

Etrenol

(Other name for: hycanthone)

Etretin

(Other name for: acitretin)

Eulexin

(Other name for: flutamide)

Evacet

(Other name for: pegylated liposomal doxorubicin hydrochloride)

everolimus

A derivative of the natural macrocyclic lactone sirolimus with immunosuppressant and anti-angiogenic properties. In cells, everolimus binds to the immunophilin FK Binding Protein-12 (FKBP-12) to generate an immunosuppressive complex that binds to and inhibits the activation of the mammalian Target of Rapamycin (mTOR), a key regulatory kinase. Inhibition of mTOR activation results in the inhibition of T lymphocyte activation and proliferation associated with antigen and cytokine (IL-2, IL-4, and IL-15) stimulation and the inhibition of antibody production. Check for or using this agent. ()

Evista

(Other name for: raloxifene)

Evoxac

(Other name for: cevimeline hydrochloride)

ex vivo-expanded HER2-specific T cells

T cells specific for the human epidermal growth factor receptor 2 (HER2) with potential immunopotentiating activity. T cells directed against HER2, overexpressed on many tumor cells, are collected from HER2-expressing tumor tissue, expanded ex vivo and, then re-introduced in the patient. Re-introduction of ex vivo-expanded HER2-specific T cells may enhance the cytotoxic T cell response against tumor cells overexpressing HER2, resulting in inhibition of tumor growth. Check for or using this agent. ()

exatecan mesylate

A semisynthetic, water-soluble derivative of camptothecin with antineoplastic activity. Exatecan mesylate inhibits topoisomerase I activity by stabilizing the cleavable complex between topoisomerase I and DNA and inhibiting religation of DNA breaks, thereby inhibiting DNA replication and triggering apoptotic cell death. This agent does not require enzymatic activation and exhibits greater potency than camptothecin and other camptothecin analogues. Check for or using this agent. ()

exemestane

A synthetic androgen analogue. Exemestane binds irreversibly to and inhibits the enzyme aromatase, thereby blocking the conversion of cholesterol to pregnenolone and the peripheral aromatization of androgenic precursors into estrogens. Check for or using this agent. ()

Exherin

(Other name for: ADH-1)

exisulind

An inactive metabolite of the nonsteroidal, anti-inflammatory agent sulindac. After oral administration, sulindac undergoes extensive biotransformation including irreversible oxidation to sulindac sulfone. Approximately, one half of an administered dose of sulindac is eliminated through the urine, mostly as the conjugated sulfone metabolite. Check for or using this agent. ()

Exjade

(Other name for: deferasirox)

Extren

(Other name for: acetylsalicylic acid)

ezatiostat hydrochloride

The hydrochloride salt of a liposomal small-molecule glutathione analog inhibitor of glutathione S-transferase (GST) P1-1 with hematopoiesis-stimulating activity. After intracellular de-esterification, the active form of ezatiostat binds to and inhibits GST P1-1, thereby restoring Jun kinase and MAPK pathway activities and promoting MAPK-mediated cellular proliferation and differentiation pathways. This agent promotes the proliferation and maturation of hematopoietic precursor cells, granulocytes, monocytes, erythrocytes and platelets. Check for or using this agent. ()
