Taking the 1 mL working solution as an example, add 30 mg of this product to 1 ml of physiological saline (0.9% NaCL solution), mix evenly to make it clear, The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

Betaxolol (SL 75212) is a β₁ adrenergic receptor blocker with IC50 of 6 μM.

Targets

β1-adrenergic receptor ^[1]

6 μM

In vitro

Betaxolol is able to protect retinal neurones. ^[2] Betaxolol attenuates the NMDA-induced influx of ⁴⁵Ca²⁺ while β-adrenoreceptor agonists are ineffective. ^[3] The glutamate-induced release of LDH is almost completely prevented when betaxolol (10 μM) is included. ^[4] Betaxolol (100 μM) is very effective in preventing the hypoxia-induced release of LDH from cortical cultures. ^[5]

In vivo

When Betaxolol is injected i.p. into the rats before ischaemia and on the days of reperfusion the changes to the calretinin and ChAT immunoreactivities are reduced and the reduction of the b-wave is prevented. Inclusion of betaxolol partially prevents the changes caused by NMDA and lack of oxygen/glucose. ^[5]

Protocol (from reference)

Cell Assay:^{^[5]}	Cell lines Dissociated rat cortical cells Concentrations 100 μM Incubation Time 4 hours Method Dissociated cortical cells from 16–18-day-old fetal rats are grown, in 35 mm dishes, in DMEM supplemented with L-glutamine (4 mM), glucose (6 g/L), penicillin (100 U/mL), streptomycin (100 μg/mL) and 10% hormonal supplemented medium consisting of transferrin (1 mg/mL), insulin (250 μg/mL) putrescine (600 μM), sodium selenite (0.3 μM), progesterone (0.2 μM) and estradiol (0.1 pM) for 7 days in an atmosphere of 5% CO₂/95% O₂ at 37 °C. The cultures are then transferred to a culture medium which lacks the hormonal supplemented medium. L-glutamate is added to the medium and incubated for a further 4 hours under normoxic conditions. Betaxolol are added to the cultures at the same time as L-glutamate. In other experiments the cultures are subjected to anoxic conditions, 95% N₂/5% CO₂, for 5 hours at 37 °C. Betaxolol is added prior to anoxia. Reoxygenation is then achieved by replacing the cells in normoxic conditions (95% O₂/5% CO₂) for 3 hours. Cellular injury is assessed by measuring lactate dehydrogenase (LDH) release into the cell culture supernatant after hypoxia/reoxygenation or glutamate exposure. LDH activity is assayed spectrophotometrically by following NADH metabolism for 2 minutes at 340 nm.
