The synthesis and antihypertensive activity of a series of 2,4-dioxoimidazolidin-1-yl and perhydro-2,4-dioxopyrimidin-1-yl ergoline derivatives are reported. The oral antihypertensive activity was studied in spontaneously hypertensive rats (SHRs) by measuring systolic blood pressure by an indirect tail-cuff method at different times after treatment. The prolactin lowering activity (indirectly measured
报道了一系列2,4-二氧杂咪唑啉-1-基和过氢-2,4-二氧嘧啶亚基-1-基麦角灵衍生物的合成和降压活性。通过在治疗后的不同时间通过间接尾袖法测量收缩压来研究自发性高血压大鼠(SHRs)的口服降压活性。还研究了大鼠的催乳激素降低活性(通过硝化试验间接测定)和小鼠的口服急性毒性。这项研究的结果表明,有效的降压麦角灵衍生物没有与多巴胺能刺激有关的副作用,而且δ9,10双键对于在这些化合物中赋予高效力具有重要意义。
