  Synthesis of 1,8-naphthyridine derivatives: Potential antihypertensive agents — Part VII

  摘要：

  A series of 2-(carbethoxypiperazinyl)- and 2-piperazinyl-1,8-naphthyridine derivatives, variously substituted, have been synthesized and pharmacologically investigated for their antihypertensive activity. Some of them exhibited a significant and prolonged decrease of the mean arterial pressure (MAP) on spontaneously hypertensive rats. For this series of compounds, on the basis of the pharmacological results obtained, no structure-activity relationship can be deduced at this time. Moreover, the most active and representative compounds 11b, 12a and 16b were investigated by means of in vitro pharmacological functional studies and in vivo, as diuretic agents, to determine a possible mechanism of the antihypertensive activity, which is unknown for the moment.

  A series of 1,8-naphthyridine derivatives variously substituted in the 2, 3, 4 and 7 positions were synthesized for in vitro evaluation of antimycobacterial activity in accordance with an international program with the tuberculosis antimicrobial acquisition and coordinating facility (TAACF). Several compounds 4, 8, 12, 14, 19, 29 and 30, when tested at a concentration of 6.25 microg/ml against Mycobacterium
