CALP1 TFA 

CALP1 TFA is a calmodulin (CaM) agonist (K_d of 88 µM) with binding to the CaM EF-hand/Ca²⁺-binding site. CALP1 TFA blocks calcium influx and apoptosis (IC₅₀ of 44.78 µM) through inhibition of calcium channel opening. CALP1 TFA blocks glutamate receptor channels and blocks a store-operated nonselective cation channel. CALP1 TFA activates CaM-dependent phosphodiesterase activity^[1][2][3][4].
