<p>N,N-Diethyl-5-methyl-[1,2,4]triazolo[5,1-b]pyrimidin-7-amine (MTX) is a drug that is used in the treatment of disease activity. It has been shown to have an effect on the production of redox potentials and energy metabolism. MTX also has an effect on cardiac muscle by inhibiting the enzyme activities associated with cardiac muscle contraction and relaxation. This drug has been shown to be effective in the treatment of bowel disease, injury, and basic protein as well as caproic acid production.</p>

<p>4,4'-Bis(ethoxycarbonyl)-2,2'-bipyridine (BEBCP) is a dithiolate chromophore. BEBCP has a redox potential of 1.3 volts and the electronic interaction of the carbonyl groups with the electron cloud of the bipyridine nucleus is responsible for this property. The photochemical properties of BEBCP can be systematically studied by using electrochemical data such as voltammetry and cyclic voltammetry. These methods are useful in determining the nature and constant of BEBCP as well as its interaction with ligands.</p>
