CALP3

Research use only, not for human use.

Cell-permeable calmodulin (CaM) agonist that binds to the EF-hand/Ca2+-binding site. Activates phosphodiesterase in the absence of Ca2+ and inhibits Ca2+-mediated cytotoxicity and apoptosis (IC50 = 33 μM).

CALP3 (50, 100, 150, 200 μM) inhibits glutamate caused a large sustained increase in [Ca2+]i in a dose-dependent manner (IC50=37.25 μM) in Fura-2-loaded neuronal cultures. CALP3 (50, 100, 150, 200 μM) inhibits glutamate-induced cytotoxicity in a dose-dependent manner (IC50=50.97 μM) in cultured rat neocortical neurons. CALP3 causes dose-dependent inhibition of apoptosis (IC50=33.41 μM).CALP3 (100 μM) inhibits apoptosis induced by HIV gp120 and SAg in Human T cells. CALP3 (100?μM; 15?min pretreatment) reduces gossypol-induced necrosis and increases the fraction of live cells. Cyclic-CALP3 is synthesized starting from Fmoc-Asp(PEG-PS)-OAl. Cyclic CALP3 is unable to inhibit Ca21 influx, and this peptide served as a negative control. Cyclic CALP3 does not inhibit the effect of glutamate.
