生物活性

NS309 is a potent and selective activator of the Ca2+-activated SK/IK potassium channels, but displays no activity at BK channels[1][2][3][4].

IC50 & Target

EC50: 0.62 µM (SK2)[1], 0.3 μM (SK3)[2], ∼20 nM (KCa3.1/SK4)[3], ∼600 nM (KCa2/SK channels)[3], 10 nM (hIK)[4]

体外研究
(In Vitro)

NS309 (40 nM) activates both hSK3 and hIK channels, with the largest effect on hIK channels (8.5-fold increase in current compares to 1.9-fold increase in current for hSK3 channels)[2].
NS309 (10 μM) significantly increases the whole cell SK currents and hyperpolarized detrusor smooth muscle (DSM) cells resting membrane potential[5].
NS309 inhibits the spontaneous phasic contraction amplitude, force, frequency, duration and tone of isolated DSM strips in a concentration-dependent manner[5].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

NS309 (2 mg/kg; i.p.) protects against SCI/R in rabbits[6].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Adult New Zealand white rabbits (2.5-3.0 kg)[6]
Dosage: 2 mg/kg
Administration: Intraperitoneal injection
Result: Significantly improved neurological outcome of SCI/R challenged rabbits.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
