In order to investigate the origin of the loop-type diuretic activity of M17055 (1), several variants (3-9) were designed and synthesized by modifying the quinolinone skeleton, and their diuretic activities were compared with the lead 1 and furosemide in dogs. It was found that the negative charge distribution pattern afforded by the dispositional arrangement of the 4-oxime-O-sulfonic acid and 1-N-acyl
为了研究M17055(1)的环状利尿作用的起源,设计并合成了几种变体(3-9),方法是修饰喹啉酮骨架,并将它们的利尿作用与狗中的Lead 1和呋塞米进行比较。 。已经发现,由附着在四氢吡啶环系统上的4-肟-O-磺酸和1-N-酰基羰基部分的排列排列所提供的负电荷分布模式对于活性的发展是不可避免的,这强烈支持了Na(+)-K(+)-2Cl(-)共转运蛋白活性位点的先前提出的模型。还报道了化合物9的合成所需的二氢噻吩并[3,2-b]吡啶-7(4H)-单环系统的首次合成。
