β-blockers: their new life from hypertension to cancer and migraine

Publication date: Available online 3 December 2019Source: Pharmacological ResearchAuthor(s): Carlo Fumagalli, Niccolò Maurizi, Niccolò Marchionni, Diego FornasariAbstractThe pharmacological class of β-blockers includes a plea of molecules with largely different pharmacokinetic and pharmacodynamic characteristics with a protective effect that may span far beyond the cardiovascular system. Although all these compounds share the pharmacological blockade of the adrenergic receptors, each of them is characterized by specific pharmacological properties, including selectivity of action depending on the adrenergic receptors subtypes, intrinsic sympathomimetic activity (ISA), lipid solubility, pharmacokinetic profile, and also other ancillary properties that impact their clinical effect. Their use in the treatment of hypertension has been extensively debated and at the moment a class indication is not present. However, in specific niche of patients, such as in those young individuals in which hypertension is mainly driven by a sympathetic hyperactivation, strong evidence pose β-Blockers as a highly reasonable first-line treatment. Lipophilic β-blockers, specifically propranolol and metoprolol, can cross the Blood Brain Barrier and have a Class A indication for the prophylactic treatment of migraine attacks. Moreover, since β-adrenergic receptors affect the proliferative process of both cancer and immune cells, their blockade has been associated with ...

High blood pressure is prevalent in the UK, with around one in three people living with it in the UK, yet many people will not realise they have it because it rarely produces any outward signs. To prevent high blood pressure, it is important to make healthy dietary decisions, and a popular ingredient has been shown to reduce high blood pressure.

This study deals with the coordination of bilateral synchronous and asynchronous hand movements. Cooperative hand movements (e.g. opening a bottle) were shown to be coordinated by a neural coupling, reflected in the appearance of reflex responses in forearm muscles of both sides to unilateral arm nerve stimulation. The mechanical effect of this neural coupling was investigated during bilateral synchronous and asynchronous sinusoidal tracking tasks. During the synchronous tracking task, right handed corrective movements were mirrored by the left hand, suggesting a neural coupling. During the asynchronous tracking task, larg...

The chemical structures of individual hybridized GSE derivatives were identified as 3'-O-decanoyl catechin, 3′-O-decanoyl epicatechin, 3', 5'-2-O-decanoyl epigallocatechin, and 3', 4', 3'', 5''-4-O-decanoyl epicatechin gallate by HPLC-MS2 and 1H and 13C NMR.
