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+.
Caloxin 2A1 is an inhibitor peptide of the plasma membrane Ca 2+-ATPase (PMCA) responsible for extracellular signaling. Importantly, Caloxin 2A1 has no impact on the basal Mg 2+-ATPase or Na+-K+-ATPase activities.
Secalonic acid D 是一种抗肿瘤细胞的有毒化合物。Secalonic acid D 可以从Aspergillus aculeatus 的代谢产物中分离得到。Secalonic acid D 激活GSK3-β,并降解β-catenin。因此,Secalonic acid D 下调c-Myc 表达,使细胞周期停滞在 G1 期,诱导细胞凋亡 (apoptosis)。
