A series of phthalazinyl- and quinoxalinylguanidines has been synthesized and evaluated for potential antihypertensive activity. Unsubstituted guanidines were prepared by treating the appropriate intermediate chloro compounds with guanidine free base. Substituted guanidines were prepared by treating the cyanamides 9 and 16 with the appropriate amine; with hydrazines, cyanamide 9 gave the triazoles
已经合成了一系列的酞菁基和喹喔啉基胍,并评估了其潜在的降压活性。通过用胍游离碱处理适当的中间体氯化合物来制备未取代的胍。取代的胍是通过用适当的胺处理氰胺9和16制备的;与肼一起使用时,氰胺9可使三唑14和15下降。对于化合物10、11、14和15,血压会适度下降。三唑15可使心率下降25%。某些化合物(10、11、13和18)在体外表现出较弱的α-肾上腺素受体拮抗剂特性,这种活性已在有髓大鼠体内(体内)得到证实。
