(S)-(−)-Propranolol hydrochloride has been used:
  • as a non-selective β-blocker propranolol to inhibit the actions of epinephrine in mice
  • as a β1- and β2-aadrenergic receptor blocker in rat
  • as a medium supplement to investigate its effect on adipogenesis in hemangioma-derived stem cells (HemSC)

Biochem/physiol Actions

(S)-(−)-Propranolol hydrochloride is biologically active enantiomer. It acts as β1 receptor antagonist in thalamocortical neurons. (S)-(−)-Propranolol hydrochloride elicits its inhibitory function on the β1 adrenoceptor in trigeminovascular pain pathway and serves as a preventive medicine in migraine.
Active β-adrenoceptor blocking enantiomer, as measured by inhibition of isoprenaline-induced tachycardia; Propranolol is also non-specific 5-HT1A, 5-HT1B and 5-HT1C serotonin receptor antagonist. The stereoselective association of mianserin and propranolol with the 5HT1A, 5HT1B and 5HT1C sites may prove useful in the characterization of these sites

Moderate dietary protein restriction promotes hyperphagia and thermogenesis; however, little is known of whether these responses are due to restriction of the essential amino acids tryptophan and histidine. Here, we determined whether restriction of tryptophan and histidine alone recapitulate the...
