| Description | ZT-1a is a SPAK inhibitor.ZT-1a inhibits SPAK.ZT-1a can be used for the prevention and treatment of neurodegenerative and neurocognitive disorders. |
| In vitro | ZT-1a inhibits the Na-K-2Cl cotransporter (NKCC1) and stimulates the K-Cl cotransporter (KCC) by reducing its SPS1-related proline/alanine-rich kinase (SPAK) dependent phosphorylation[1].At 1 μM ZT-1a, NKCC1 p-Thr203/207/212 phosphorylation is inhibited by 72±5.2%, and in HEK-293 cells, KCC phosphorylation at sites 1/2 is inhibited by 65-77% at 3 μM ZT-1a[1].Phosphorylation of SPAK at the Ser373 site is inhibited by 70±3.8% at 3-10 μM ZT-1a[2]. ZT-1a (10 μM) inhibits NKCC1 but stimulates KCC3 activity[2]. |
| In vivo | ZT-1a inhibits the SPAK-dependent upregulation of NKCC1 and KCC3 phosphorylation in ischemic brains.post-stroke treatment with ZT-1a protects both gray and white matter tissues in ischemic brains[1]. |
