for their ability to displace specific [3H]flunitrazepam from bovine brain membranes. The substitution pattern of the above derivatives was shown to influence the receptor affinity. The most active compound of the series was 7e, showing a 54% inhibition of [3H]flunitrazepam binding. Compounds 7aed,i were compared with the known isomers chromeno[4,3-c]pyrazole-4(1H)-ones 14aed,i, showing that the isochromene/chromene isomerism influences the activity.
