A series of "A" ring substituted sulmazole and isomazole analogues have been prepared and evaluated as inotropic agents. pKA's, protonation sites, and log P values were measured for selected compounds and their electronic properties were calculated. No simple correlation between inotropic activity and pKA, protonation site, or log P value was observed. However, in vitro inotropism did correlate with
已经制备了一系列“ A”环取代的舒马唑和异咪唑类似物,并评价为正性肌力药。测量所选化合物的pKA,质子化位点和log P值,并计算其电子性能。在正性肌力活动与pKA,质子化位点或log P值之间未发现简单的相关性。但是,体外变力性确实与“ B”环咪唑氮原子的电荷密度相关。舒马唑的6-位似乎对取代基具有最高的耐受性,6-氨基衍生物7比舒马唑本身更有效。4-甲氧基异唑13具有与异唑相当的体内正性肌力。
