Fluorescamine: a reagent for assay of amino acids, peptides, proteins, and primary amines in the picomole range.
Fluorescamine is a new reagent for the detection of primary amines in the picomole range. Its reaction with amines is almost instantaneous at room temperature in aqueous media. The products are highly fluorescent, whereas the reagent and its degradation products are nonfluorescent. Applications are discussed.

Isolation and identification of "diazepam-like" compounds from bovine urine.
Attempts to isolate the putative endogenous ligand for the benzodiazepine receptor from bovine urine resulted in the identification of three isoflavans: equol (1), 3',7-dihydroxyisoflavan (2), and 4'-hydroxy-7-methoxyisoflavan (9), as "diazepam-like" compounds. 3-Chloro-9H-carbazole (17) was found to enhance the binding of diazepam in the benzodiazepine receptor binding assay. Pinosylvine monomethyl ether (18), indigo (20), and indirubin (21) were isolated as inactive compounds.
