Potent and orally active Cav3.1 & Cav3.3 T-type voltage-gated Ca2+ channel (T-VGCC) enhancer with in vivo cognitive deficits-improving efficacy. |
| Biochem/physiol Actions: |
SAK3 is a potent and orally active spiroimidazopyridine derivative that enhances Cav3.1 and Cav3.3, but not Cav3.2, T-type voltage-gated Ca2+ channel (T-VGCC) activity (∼20% peak current increase with 0.1 nM SAK3 by whole-cell patch-clamp using human Cav3.1 or Cav3.3 transfected neuro2A; no effect up to 10 nM using Cav3.2 transfectant). Acute SAK3 oral administration (0.5 mg/kg) significantly enhances hippocampal CA1 region acetylcholine (ACh) release in naïve mice, as well as increases hippocampal ACh levels and improves memory deficits among olfactory-bulbectomized (OBX) mice. Daily SAK3 oral administration 24 hrs following hypothyroidism induction by methimazole (MMI) is efficacious against MMI-induced medial septum (MS) cholinergic neurons loss (0.5-1 mg/kg/day) and cognitive deficits (1 mg/kg/day). |
