Xestospongin C ((-)-Xestospongin C) 是一种具有选择性的肌醇 1,4,5-三磷酸受体 (IP3R) 抑制剂,也是肌膜/内质网 Ca2+ ATP 酶 (SERCA) 的抑制剂,对 APP/PS1 AD 小鼠认知行为和病理学具有神经保护作用,可减轻阿尔茨海默病 APP/PS1 小鼠的认知和病理障碍。
Mycalolide-B is a marine sponge-derived compound that functions as a selective inhibitor of actomyosin ATPase. It effectively hinders ATP-induced contraction and Mg2+-ATPase activity in the absence of Ca2+.
Bassianin, a fungal metabolite identified in Beauveria, demonstrates inhibition of Mg2+-, Ca2+-, and Na+/K+-ATPase activities in equine erythrocyte ghosts, with inhibition rates of 81%, 58%, and 23%, respectively, at a concentration of 200 µg/ml. Additionally, bassianin exhibits cytotoxic properties against Sf9 and Sf21 insect cells, with 50% cytotoxic concentration (CC50) values of 4.91 µM and 12.12 µM, respectively.
