The present paper reviews the active, natural principles and crude extracts of plants which
have been experimentally studied for hypoglycemic activity in the last ten years. …

The effect of beta-sitosterol 3-beta-glucoside (antihyperglycemic principle isolated from the
aerial part of Centaurea seridis L. var. maritima Lge.) and its aglycone on plasma insulin and …

The effect of tormentic acid, a natural product isolated from Poterium ancistroides, was studied
in normoglycemic, hyperglycemic, and streptozotocin diabetic rats. This principle lowered …

Background and Purpose To analyse the relative contribution of β 1 ‐, β 2 ‐ and β 3 ‐adrenoceptors
(Adrb) to vasodilatation in conductance and resistance vessels, assessing the role …

Pharmacology has broadened its scope considerably in recent decades. Initially, it was of
interest to chemists, doctors and pharmacists. In recent years, however, it has been …

Downregulation of β 1 - adrenergic receptors (β 1 -ARs) and increased expression/function
of G-protein-coupled receptor kinase 2 (GRK2) have been observed in human heart failure, …

Looking for antihypertensive mechanisms beyond ACE inhibition, we assessed whether
lactoferrin (LF)-derived peptides can act as receptor blockers to inhibit vasoconstriction induced …

The mRNA levels for the three α 1 -adrenoceptor subtypes, α 1A , α 1B , and α 1D , were
quantified by real-time RT-PCR in arteries from Wistar rats. The α 1D -adrenoceptor was …

Beta-Sitosterol-3-beta-D-glucoside (1) has been reported to be the active antidiabetic agent
of Centaurea seridis L. var. maritima. The present study examines the effect of oral …

Dopamine-mediated neurotransmission plays an important role in relevant psychiatric and
neurological disorders. Nowadays, there is an enormous interest in the development of new …
