We have reported previously that [8]-gingerol increased Ca2+-ATPase activity. 1, 2)Here we synthesized gingerol related compounds (AP-004, AP-005 and AP-015) and investigated the effects of gingerols ([6]-gingerol, [8]-gingerol and [10]-gingerol) and the synthesized compounds on the Ca2+-ATPase activity of sarcoplasmic reticulum (SR). The Ca2+-ATPase activity and the Ca2+-pumping activity increased by these compounds in a concentration-dependent manner. It is probable that both the o-methoxyphenol and hydrocarbon chain in the molecule of gingerol analogues are necessary for the activation of the Ca2+-pumping ATPase activity of SR.
我们之前报道过 [8]-姜酚可增加 Ca2+-ATPase 活性。 1, 2)在这里,我们合成了姜辣素相关化合物(AP-004、AP-005和AP-015)并研究了姜辣素([6]-姜辣素、[8]-姜辣素和[10]-姜辣素)的作用和合成了对肌浆网 (SR) Ca2+-ATPase 活性的化合物。这些化合物以浓度依赖性方式增加Ca2+-ATP酶活性和Ca2+泵活性。姜酚类似物分子中的邻甲氧基苯酚和烃链很可能对于激活 SR 的 Ca2+ 泵 ATP 酶活性是必需的。
