Biological Activity for YM 244769

YM 244769 is an inhibitor of the reverse mode of Na⁺/Ca²⁺ exchange (NCX). Potently inhibits Na⁺-dependent ⁴⁵Ca²⁺ uptake (IC₅₀ values are 18, 68 and 96 nM for CCL39 cells transfected with NCX3, NCX1 and NCX2 respectively). Displays selectivity for NCX over other Na⁺ and Ca²⁺ transporters. Protects against hypoxia/reoxygenation-induced cell damage in neuronal SH-SY5Y cells expressing NCX1 and NCX3.
