Application

CyPPA has been used:
  • to test its inhibitory functionality on melanogenesis
  • as an activator of small conductance potassium channel-3 (SK3) in mesenteric artery segments
  • in the activation of calcium-activated potassium (SK) channels in murine hippocampal neurons HT-22 cells

Biochem/physiol Actions

CyPPA is a positive modulator of small conductance Ca2+-activated K+ channels; selective for SK3 and SK2. CyPPA is a first subtype selective SK channel positive modulator with an EC50 of 5.6 μM and 14 μM, efficacy 90% and 71% for hSK3 and hSK2, respectively. CyPPA is a tool for distinguishing SK2 and SK3 from SK1 and IK; no other agents distinguish these channels.

N-methyl-D-aspartate receptor (NMDAR) modulates the structural plasticity of dendritic spines by impacting cytoskeletal organization and kinase signaling. In the developing nervous system, activation of NMDAR is pertinent for neuronal migration, neurite differentiation, and cellular organization. Given that small conductance potassium

Oxysterols are metabolites of cholesterol that regulate cholesterol homeostasis. Among these, the most abundant oxysterol is 27-hydroxycholesterol (27HC), which can cross the blood-brain barrier. Because 27HC functions as an endogenous selective estrogen receptor modulator, we hypothesize that 27HC binds to
