title: Synthesis and pharmacological screening of some N-(4-substituted-piperazin-1-ylalkyl)-3,4-pyrroledicarboximides.
abstract: As an extension of our previous work we describe the synthesis and pharmacological investigation of a new series of derivatives of pyrrole-3,4-dicarboximide possessing the 4-substituted-piperazin-1-ylalkyl group linked to the imide nitrogen. The products were evaluated for acute toxicity, and effectiveness in a series of CNS and arterial blood pressure tests. The preliminary pharmacological screening was determined in animal models. Several compounds demonstrated moderate to high analgesic activity in the 'writhing syndrome' test (5f-1/640 LD50). Some of the structure-activity relationships are also discussed.
