A colorimetric assay method was established for 1-(2-o-chlorobenzoyl-4-chlorophenyl)-5-glycylaminomethyl-3-dimethylaminocarbonyl-1H-1, 2, 4-triazole hydrochloride dihydrate (1), a sleep inducer, based on the reaction of 1 with 3, 5-dibromosalicylaldehyde (DBSA) to give a redcolored substance in the presence of piperidine. Our previously established method employing DBSA was also applicable to 1. Compound 1 was determined with good precision and specificity. The general applicability of the assay method to compounds containing a glycinamide group was also examined.
the corresponding NH derivatives. Some compounds had very high activities in antipentylenetetrazole and antifighting tests in mice when orally administered. Very weak toxicity was also found in these compounds. Water solubility of the peptidoaminobenzophenones and their salts were tested. Possible in these compounds. Water solubility of the peptidoaminobenzophenones and their salts were tested. Possible
