The C-terminal octapeptide of cholecystokinin-pancreozymin and its analogues in which the methionine residues were successively replaced by methoxinine have been synthesized. When these analogues were tested for their gallbladder-contraction activity in an in vitro system the following relative potencies were observed: [Mox3]-CCK-PZ 8 (95%), [Mox6]-CCK-PZ 8 (5%) and [Mox3, Mox6]-CCK-PZ 8 (2%).
已合成胆囊收缩素-促胰酶素的C末端八肽及其甲硫氨酸残基被甲硫氨酸亚砜依次取代的类似物。当在体外系统中测试这些类似物的胆囊收缩活性时,观察到以下相对效价:[甲硫氨酸亚砜3]-胆囊收缩素-促胰酶素8(95%),[甲硫氨酸亚砜6]-胆囊收缩素-促胰酶素8(5%)和[甲硫氨酸亚砜3,甲硫氨酸亚砜6]-胆囊收缩素-促胰酶素8(2%)。
