Caloxin 2A1 is primarily used in research to study calcium signaling pathways in cells. It specifically targets the plasma membrane calcium ATPase (PMCA), an enzyme responsible for calcium ion transport out of cells. By inhibiting PMCA, Caloxin 2A1 helps researchers understand the role of calcium in various cellular processes, such as muscle contraction, neurotransmitter release, and cell proliferation. This chemical is particularly valuable in experiments focused on cardiovascular and neurological systems, where calcium regulation is critical. Its application aids in uncovering mechanisms underlying diseases like hypertension, heart failure, and neurodegenerative disorders, providing insights for potential therapeutic strategies.
