Procainamide and N-acetylprocainamide (NAPA) immunogens, antibodies prepared therefrom, labeled conjugates, synthetic intermediates, and the use of such antibodies and labeled conjugates in immunoassays for determining the respective drugs. The immunogens comprise the drugs coupled at the .alpha.-position of the amide side chain to an immunogenic carrier material. The labeled conjugates and synthetic intermediates similarly are .alpha.-position derivatives of the drugs or precursors thereof. The antibodies and labeled conjugates are particularly useful in homogeneous nonradioisotopic immunoassays for measuring the respective drugs in biological fluids such as serum.

Functionalized intermediate for the synthesis of alpha-functionalized

A novel compound useful in detecting leukocytes, esterase and protease in a test sample. The compound has the structure ##STR1## in which: A is an acid residue, R is lower alkyl, aryl, carboxyl, carboxyl ester, amido or cyano, R* is H or lower alkyl, and X is O, S, or NR', in which R' is H, lower alkyl or aryl.

Method for preparing 3-hydroxy pyrroles and esters thereof

A method for preparing an ester having the structure ##STR1## in which A is an acid residue; R, same or different is H, lower alkyl, aryl, or in which both R together form a ring structure and R' is H, lower alkyl or aryl. The method comprises combining a first compound having the structure ##STR2## and a second compound which is an acyl halide corresponding to A, said combining being performed in the presence of an organic acid.

Method for synthesizing esters

Alpha-functionalized derivatives and labeled conjugates of procainamide

Pyrrole compounds for detecting the presence of hydrolytic analytes

Tricyclic antidepressant drug (e.g., imipramine, desipramine, amitriptyline, or nortriptyline) immunogens, antibodies prepared therefrom, labeled conjugates, synthetic intermediates, and the use of such antibodies and labeled conjugates in immunoassays for determining such drug. The immunogens comprise the drug coupled at its 2'-position to an immunogenic carrier material. Similarly, the labeled conjugates and synthetic intermediates are 2'-derivatives of the drug or a precursor thereof. The antibodies and labeled reagents are particularly useful in certain homogeneous nonradioisotopic immunoassays for measuring tricyclic antidepressant drugs in biological fluids such as serum.

Tricyclic antidepressant drug immunogens, antibodies, labeled

Compounds which are 3-methylene flavanones and 3-methylene chromanones having activity against microorganisms are disclosed. The compounds are represented by the general structural formula: ##STR1## wherein: R.sup.1 is a member selected from the group consisting of hydrogen, Br, CH.sub.3 and OCH.sub.3 ; R.sup.2 is selected from the group consisting of hydrogen and ##STR2## wherein R.sup.4 is a member selected from the group consisting of hydrogen, Br, Cl, CH.sub.3, OCH.sub.3, NO.sub.2, N(CH.sub.3).sub.3 and CN; R.sup.5 is selected from the group consisting of hydrogen and Cl, with the proviso that when R.sup.5 is Cl, R.sup.4 is hydrogen or Cl; and R.sup.3 is selected from the group consisting of hydrogen, phenyl, 2-thienyl, 4-pyridyl and naphthyl, with the proviso that when R.sup.3 is naphthyl, R.sup.1 and R.sup.2 are hydrogen.
