ca2+-atpase

Thapsigargin is a natural product, an inhibitor of sarcoplasmic endoplasmic reticulum Ca2+ ATPase (SERCA) and an endoplasmic reticulum stress inducer. Thapsigargin increases cytoplasmic calcium concentration by blocking the ability of cells to pump calcium into the sarcoplasmic and endoplasmic reticulum.

Arachidonic acid (Immunocytophyte) is an unsaturated, essential fatty acid. It is found in animal and human fat as well as in the liver, brain, and glandular organs, and is a constituent of animal phosphatides. It is formed by the synthesis from dietary linoleic acid and is a precursor in the biosynthesis of prostaglandins, thromboxanes, and leukotrienes.

Abscisic Acid (Dormin) is a plant hormone, which is involved in many plant developmental processes, modulates ion homeostasis and metabolism, and inhibits germination and seedling growth.

Calcimycin (A-23187) is an ionophorous, polyether carboxylic antibiotic from Streptomyces chartreusensis. It binds and transports calcium and other divalent cations across membranes, uncouples oxidative phosphorylation, and inhibits ATPase of rat liver mitochondria. The substance is primarily used as a biochemical tool to study the role of divalent cations in various biological systems.

Paxilline is an indole alkaloid mycotoxin from *Penicillium paxilli*, acting as a potent BK channel inhibitor via an almost exclusively closed-channel block mechanism. Paxilline possesses significant anticonvulsant activity.

Cyclopiazonic acid (CPA) is a neurotoxic secondary metabolite (SM) made by A. flavus. Cyclopiazonic acid (CPA) is an endoplasmic reticulum calcium ATPase (Ca2+ATPase; SERCA)nanomolar inhibitor and a potent inducer of cell death in plants.

Xestospongin C ((-)-Xestospongin C) is a selective inositol 1,4,5-trisphosphate receptor (IP3R) inhibitor and also inhibits sarcoplasmic endoplasmic reticulum Ca2+ ATPase (SERCA). It has neuroprotective effects in APP PS1 AD mice, improving cognitive and pathological deficits associated with Alzheimer's disease.

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+.

Strophanthidin (Strophanthidine) can induce calcium overload in vivo.

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.
