A series of 1-(2-amino-1-phenylethyl)-6-phenyl-4H-triazolobenzodiazepines was prepared and evaluated for diuretic activity.These compounds have diuretic and natriuretic activity but no kaliuretic activity when evaluated by oral administration to the conscious rat.The structure requirements for this activity are discussed.In particular it was found that the 2-aminoethyl side chain at C-1 with hydrogen or methyl substituents on the amino group was required for diuretic acitvity.A substituent at C-8 was also required: soft substituents such asmethylthio and iodo at this position favored activity.Compounds with both phenyl and 2-pyridyl substituents at C-6 were active; substituents on the C-6 phenyl, however, reduced or eliminated the activity.Substituents other than phenyl at the 1-position of the 2-aminoethyl side chain were detrimental to the activity; phenyl substitution at this position was required for activity when the substituent at C-8 was chloro but not when it was bromo.
