Metipranolol

Research use only, not for human use.

Metipranolol is a β-adrenergic receptor antagonist that is given orally for the treatment of hypertension and also applied topically to the cornea for treating glaucoma.

Metipranolol is a β-adrenergic receptor antagonist that is given orally for the treatment of hypertension and also applied topically to the cornea for treating glaucoma.(In Vivo):At postnatal day 35 (P35), rd10 mice given daily subcutaneous injections of 40 mg/kg of Metipranolol has reduction in markers of nitrosative stress, fewer TUNEL-positive cells, increased outer nuclear layer thickness, and substantially more staining for rhodopsin. At P50, Metipranolol-treated rd10 mice has decreased 3-nitrotyrosine staining in the retina, increased immunostaining for cone arrestin, a marker for cone photoreceptors, and significantly higher scotopic and photopic b-wave amplitudes at the highest stimulus intensity. At P65, cone density is significantly higher in Metipranolol-treated versus vehicle-injected rd10 mice.

In vitro β1- and β2-adrenoceptor antagonism is evaluated using the guinea pig atrium and the rat uterus, respectively. The respective pA2 values are 8.3 and 8.4. Metipranolol significantly reduces iron/ascorbate-induced lipid peroxidation in rat brain homogenates with an IC50 value of 6.9 μM . Metipranolol also concentration-dependently inhibits sodium nitroprusside-stimulated lipid peroxidation in rat brain homogenates, displaying an IC50 value of 25.1 μM.
