cis-urocanic acid

A derivative of the amino acid histidine, formed in the mammalian skin from trans-urocanic acid upon ultraviolet radiation, and protodynamic agent, with potential anti-inflammatory and antiproliferative activity. Upon intravesical instillation of cis-urocanic acid (cis-UCA), this agent is protonated at the imidazolyl moiety in the mildly acidic extracellular tumor environment and penetrates into the cancer cell. Once inside the cell and due to the slightly alkaline pH inside the tumor cell, cis-UCA is deprotonated, i.e. the imidazolyl proton is released into the cytosol which eventually raises the intracellular acidity. This acidification impairs many cellular processes, such as metabolic activity, and may lead to cell cycle arrest, an induction of cellular apoptosis and necrotic cell death. In addition, cis-UCA enhances ERK and JNK signaling pathways by inhibiting the activity of serine/threonine and tyrosine phosphatases. Check for or using this agent. ()

cisatracurium besylate

A non-depolarizing skeletal muscle relaxant of the benzylisoquinolinium class. Cisatracurium besylate acts as a competitive acetylcholine antagonist that binds to nicotinic receptors at the neuromuscular junction.

CoFactor

(Other name for: folitixorin)

colchicine

An alkaloid isolated from Colchicum autumnale with anti-gout and anti-inflammatory activities. The exact mechanism of action by which colchicine exerts its effect has not been completely established. Colchicine binds to tubulin, thereby interfering with the polymerization of tubulin, interrupting microtubule dynamics, and disrupting mitosis. This leads to an inhibition of migration of leukocytes and other inflammatory cells, thereby reducing the inflammatory response to deposited urate crystals. Colchicine may also interrupt the cycle of monosodium urate crystal deposition in joint tissues, thereby also preventing the resultant inflammatory response. Overall, colchicine decreases leukocyte chemotaxis/migration and phagocytosis to inflamed areas, and inhibits the formation and release of a chemotactic glycoprotein that is produced during phagocytosis of urate crystals.

The orally bioavailable copper salt of D-gluconic acid. In addition to its roles as an enzyme cofactor for cytochrome C oxidase and superoxide dismutase, copper forms complexes with the thiocarbamate disulfiram (DSF) forming DSF-copper complexes, which enhances the DSF-mediated inhibition of the 26S proteasome; proteasome inhibition may result in inhibition of cellular protein degradation, cessation of cell cycle progression, inhibition of cellular proliferation, and the induction of apoptosis in susceptible tumor cell populations.

Cordarone

(Other name for: amiodarone hydrochloride)

cordycepin

A purine nucleoside antimetabolite and antibiotic isolated from the fungus Cordyceps militaris with potential antineoplastic activity. Cordycepin is an adenosine analogue, which is readily phosphorylated to its mono-, di-, and triphosphate intracellularly. Triphosphate cordycepin can be incorporated into RNA, and inhibits transcription elongation and RNA synthesis due to the absence of a hydroxyl moiety at the 3' position. Because it can be converted to an inactive metabolite by adenosine deaminase, this agent must be administered with an adenosine deaminase inhibitor in order to be effective. Cordycepin has displayed cytotoxicity against some leukemic cell lines in vitro. Check for or using this agent. ()
