Background:

BAPTA-AM is a selective calcium chelator [1].


Ca2+ is one of the most ubiquitous and versatile intracellular signaling molecules that control numerous cellular processes such as neurotransmitter release, contraction of all muscle cell types and fertilization [4].


BAPTA-AM is a selective and membrane permeable calcium chelator. In the human leukemia cell lines HL-60 and U937, BAPTA/AM (10 μM) induced internucleosomal DNA cleavage and classic apoptotic morphology. Also, BAPTA/AM increased Ca2+ in intracellular and downregulated c-jun [1]. In bovine chromaffin cells, APTA-AM (50 μM) rapidly and reversibly inhibited Ca2+-activated K+ (I(KCa)) and voltage-gated K+ (I(K)) by 50% [2]. In HEK 293 cells, BAPTA-AM inhibited hERG (Kv11.1), hKv1.3 and hKv1.5 channels with IC50 values of 1.3, 1.45 and 1.23 μM respectively in a concentration dependent way, which was dependent on channel opening [3].


In swiss mice, BAPTA-AM inhibited locomotor stimulation produced by ethanol and reversed ethanol-induced hypnotic effects. In male C57BL/6J mice, BAPTA-AM reduced ethanol consumption in a dose-dependent way [4].
