Routine screening of compounds for inhibition of ADP-inducedplateletaggregation in vitro revealed that 1,1'-hexamethylenebis[3-cyclohexyl-3-[(cyclohexylimino) (4-morpholinyl) methyl]urea] (1) was active and represented the first example of a bis(acylguanidine) with possible antithrombotic activity. In order to develop a structure-activity relationship for this class of compounds, we synthesized a

nonkaliuretic diuretic in rats. The diuretic profile of 1 and its 1-adamantyl analog (U-37883A, 4) was confirmed orally in dogs, when they were less potent than standard diuretics but showed furosemide-like natriuresis at > or = 100 mumol/kg. However, acute 1 at 61 and 90 mumol/kg iv resulted in lethal cardiac toxicity in dogs. Many analogs of 1 exhibited qualitatively similar diuretic profiles, but
随机筛选确定N,N'-二环己基-4-吗啉羧box(U-18177,1)为大鼠口服有效的非利尿剂利尿剂。在狗中口服1和其1-金刚烷基类似物(U-37883A,4)的利尿特性时,它们的功效不如标准利尿剂,但在>或= 100 mumol / kg时显示了速尿类似的利尿作用。但是,急性1在61和90 mumol / kg iv静脉注射可导致犬致命的心脏毒性。1的许多类似物在质上表现出相似的利尿特性,但没有一个足以保证发育。化合物1还逆转了米诺地尔在犬中的血管舒张作用,这导致了血管相互作用的研究表明,类似物4可能会阻断ATP敏感的K通道。这种钾通道阻滞机制可能有助于该系列的利尿活性。
