contractile responses on isolated guinea pig trachea. The cis double-bond geometry appears to be critical for antagonist activity, whereas the trans isomer 17 exhibited weak contractile activity. Replacement of the cysteinylglycyl moiety with cysteine afforded 20, which retained significant antagonist activity, while lengthening or shortening the lipid tail by five methylene groups resulted in complete loss
合成了一系列4(R)-羟基-5(S)-半胱氨酰甘氨酰基-6(Z)-十九碳烯酸[4R,5S,6Z)-2-nor-LTD1(10b,SK&F 101132)的结构类似物和药理学特征。(4R,5S,6Z)-2-nor-LTD1显着拮抗LTD4诱导的对豚鼠气管的收缩反应。顺式双键几何形状似乎对拮抗剂活性至关重要,而反式异构体17表现出较弱的收缩活性。用半胱氨酸代替半胱氨酰糖基部分得到20,其保留了显着的拮抗剂活性,同时通过五个亚甲基延长或缩短脂质尾巴导致活性完全丧失。类花生酸酰胺15,甘氨酰胺14和C-1甲醇18类似物均具有拮抗活性,
