In Vitro	CyPPA induces a concentration-dependent increase in the apparent Ca2+-sensitivity of channel activation, changing the EC50 (Ca2+) from 429 nM to 59 nM[1].
In Vivo	CyPPA, a positive modulator of small-conductance Ca2+-activated K+ channels, inhibits phasic uterine contractions and delays preterm birth in mice[2].
