studied analogs are ones in which a mobile proton is attached to an O or N atom. In a search for new selective bronchodilators a series of catecholamine analogs bearing a substituted sulfonyl or sulfonylalkyl group in the meta position (i.e., groups in which the mobile H is attached to a C atom) was examined. These compounds were studied for beta-adrenergic agonist activity in vitro by measuring their
儿茶酚胺β-肾上腺素能激动剂的间苯酚基团可以被能够进行氢键键合的各种官能团取代。在保持活性的情况下,允许在OH模拟基团的性质上有很大的自由度;然而,研究最广泛的类似物是将移动质子连接到O或N原子的类似物。为了寻找新的选择性支气管扩张剂,研究了一系列在间位带有取代的磺酰基或磺酰基烷基的儿茶酚胺类似物(即,移动的H连接到C原子上的基团)。通过测量这些化合物舒张气管平滑肌和增加豚鼠右心房自发搏动的速率,研究了它们在体外的β-肾上腺素能激动剂活性。肾上腺素能的活性受磺酰基和芳族基团之间亚烷基桥的性质,乙醇胺侧链的支化,立体化学以及磺酰基和氨基的取代的影响。对于某些磺酰基直接连接在环上的化合物,发现存在β-肾上腺素能阻滞作用。使用m-MeSO2CH2取代基观察到最大的β-肾上腺素能激动剂效能和组织选择性。其中的一种化合物,α-[[((1,1-二甲基乙基)氨基]甲基] -4-羟基-3-[(甲基磺酰基)
