Bioactivity | ATPγS (tetralithium salt) is a substrate for the nucleotide hydrolysis and RNA unwinding activities of eukaryotic translation initiation factor eIF4A[1]. |
Invitro | ATPγS (tetralithium salt) enhances intrinsic fluorescence and induces aggregation which increases the activity of spinach Rubisco activase[1].ATPγS (50-100 μM final blood concentration) attenuates inflammatory response with decreased accumulation of cells (48%, P < 0.01) and proteins (57%, P < 0.01) in bronchoalveolar lavage and reduces neutrophil infiltration and extravasation of Evans blue albumin dye into lung tissue[3]. |
In Vivo | ATPγS (tetralithium salt, 50 μM final, intravenous) demonstrates preserved lung parenchymal architecture[3].ATPγS results in a dose-dependent effect on EBA extravasation in LPS-treated mice[3]. |
