A series of 6-substituted-9-(3-formamidobenzyl)purines were synthesized and studied for benzodiazepinereceptor (BZR) bindingactivity. Most of the target compounds were prepared by reaction of 6-chloro-9-(3-formamidobenzyl)-9H-purine (17) with the appropriate amine, alcohol or other nucleophilic reagent. Alternatively, the 6-cyclopropylaminopurine 5 was synthesized via the nitrobenzyl precursor 22

to the benzodiazepinereceptor (BZR) in rat brain tissue. The most active compound was the 8-bromo-9-(3-formamidobenzyl) analogue 16 (IC50 = 0.011 microM), which was 1000-fold more active than the parent 9-benzyl-6-(dimethylamino)-9H-purine (1) and nearly as active as diazepam. Although substitution of a m-formamido group and an 8-bromo substituent on 1 imparted potent BZR bindingactivity, neither
