钙离子载体A23187是一种羧酸类抗生素，在体外抗革兰氏阳性菌的活性较弱。它可增加二价离子穿过生物膜的电位，因此起到离子载体的作用。钙离子载体A23187特异性地与二价阳离子形成稳定的2:1复合物，使这些离子可溶于普通有机溶剂。由于钙离子载体A23187通常用于增加完整细胞内的Ca2+水平，它可用作氧化磷酸化的解偶联剂和线粒体腺苷三磷酸酶（ATPase）活性的抑制剂。钙离子载体A23187是弓形虫真核起始因子-2α（eIF2α）磷酸化作用的有效诱导物。此外，它不仅在小鼠淋巴瘤系（S49）7中诱导凋亡；还显示出可以阻断其他系统中的凋亡，例如当白介素3（IL-3）从IL-3依赖性细胞中除去时。钙离子载体A23187广泛用作人卵母细胞的人工辅助激活物。
Application
离子载体对Ca2+具有高度选择性。 增强对NMDA的反应，而不是使君子氨酸。 在细胞培养中，通过钙调素依赖的构成型一氧化氮合酶刺激一氧化氮的产生。
钙离子载体A23187已：
- 用作内质网（ER）应激诱导剂，以研究其对弓形虫未折叠蛋白反应（UPR）基因表达的影响
- 用于诱导顶体反应
- 用于骨骼肌肌浆网Ca2+ATPase (SERCA)的活性测定

Bioactivity-guided fractionation of an ethanolic extract of the rhizome of Pleuranthodium racemigerum, a tropical Zingiberaceae species from Northeastern Australia, resulted in the isolation and structural elucidation of 1-(4''-methoxyphenyl)-7-(4'-hydroxyphenyl)-(E)-hept-2-ene (1), a new diarylheptanoid related to curcumin. Compound 1 was a fairly

In blood platelets the small GTPase Rap1b is activated by cytosolic Ca2+ and promotes integrin αIIbβ3 inside-out activation and platelet aggregation. cAMP is the major inhibitor of platelet function and antagonizes Rap1b stimulation through a mechanism that remains unclear. In
