Abstract
Glutarimide derivatives of the formula which are useful antihypertensive and antianxiety agents ##STR1## wherein R.sub.1 and R.sub.2 each independently represent hydrogen, a 1 to 4 carbon alkyl, a 1 to 4 carbon alkoxy, halogen, nitro, hydroxy, SO.sub.3 H, SO.sub.2 NH.sub.2, and when R.sub.1 and R.sub.2 are taken together, form a fused phenyl group at the 1,2- or 3,4- positions, with the proviso that when R.sub.1 and R.sub.2 are identical they each represent a hydrogen, a 1 to 4 carbon alkyl, a 1 to 4 carbon alkoxy, hydroxy or a halogen group; A and B independently represent an oxo, a thio or an imino group having the formula --N(R.sub.6)-- wherein the R.sub.6 group is hydrogen or a 1 to 4 carbon alkyl group; R.sub.3 is a hydrogen, a 1 to 4 carbon alkyl or hydroxyethyl group; n is an integer of from 2 to 5; and R.sub.4 and R.sub.5 represent methyl groups or when taken together form a cyclopentane or cyclohexane ring; its enantiomers; and the pharmaceutically acceptable acid addition salts thereof.
