生物活性

SKA-121 is a selective KCa3.1 activator. SKA-121 exhibits EC50s of 109 nM and 4.4 μM for KCa3.1 and KCa2.3, respectively.

IC50 & Target

EC50: 109 nM (KCa3.1), 4.4 μM (KCa2.3)[1]

体外研究
(In Vitro)

SKA-121, a compound generated through an isosteric replacement approach. SKA-121 is a typical positive-gating modulator and shifts the calcium-concentration response curve of KCa3.1 to the left. SKA-121 displays 41-fold selectivity for KCa3.1 (EC50 109 nM±14 nM) over KCa2.3 (EC50 4.4 ± 1.6 μM). SKA-121 is 200- to 400-fold selective over representative KV (KV1.3, KV2.1, KV3.1, and KV11.1), NaV (NaV1.2, NaV1.4, NaV1.5, and NaV1.7), as well as CaV1.2 channels[1].

体内研究
(In Vivo)

In blood pressure telemetry experiments, SKA-121 (100 mg/kg i.p.) significantly lowers mean arterial blood pressure in normotensive and hypertensive wild-type but not in KCa3.1-/- mice. SKA-121 can be used as a new KCa3.1 selective pharmacological tool compound despite its relatively short half-life in mice. A lower dose of 30 mg/kg of SKA-121 does not produce significant alterations in MAP. The vehicle, peanut oil/DMSO (9:1 v/v, for SKA-121), does not cause significant alterations in MAP or HR. SKA-121 has a short half-life (~20 minutes), and plasma decay is extremely rapid (21.3±2.4 μM at 5 minutes; 483±231 nM at 1 hour and 53±44 nM at 4 hours). Since SKA-121 is relatively well soluble (logP=1.79) and can potentially be added to drinking water in animal experiments, it orally is also administered, and find that it has an oral availability of roughly 25%[1].

Kinase Assay
[1]

To fully evaluate the selectivity of the naphthooxazole SKA-121, seven-point concentration-response curves on KCa2.1, KCa2.2, KCa2.3 and KCa3.1 are determined with 250 nM free Ca2+ in the internal solution[1].

Animal Administration
[1]

Mice[1]
Twelve-week-old male C57Bl/6J mice are used. For i.v. application, SKA-121 is dissolved at 5 mg/mL in a mixture of 10% CremophorEL and 90% phosphate-buffered saline and then injected at 10  mg/kg into the tail vein (n=8 mice per compound). Another group of mice (n=8) receive SKA-121 orally. At various time points after the injection, blood is collected into EDTA blood sample collection tubes either from the saphenous vein or by cardiac puncture under deep isoflurane anesthesia. After the cardiac puncture, mice are sacrificed by cutting the heart, and then the brain is removed. Individual mice are typically used for three times points (two blood collections from the saphenous vein plus the terminal blood collection).

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.
