[Effect of adrenergic beta-agonist on intracellular free calcium concentration in isolated acini of the parotid gland in rats].

Comptes rendus des seances de la Societe de biologie et de ses filiales, 1996
The variations in the intracellular free calcium concentration, [Ca2+]i, have been studied in isolated acini of rat parotid gland with a fluorescent probe, fura-2. In unstimulated acini, [Ca2+]i amounted to a basal value of 180 nM. Isoproterenol used at a concentration of 200 microM, in the presence of a beta-adrenergic blocker, caused a net increase ...

Molecular orbital studies on the mechanism of drug-receptor interaction. 5. Molecular reactivity and receptor affinity of beta-agonist adrenergic drugs.

Drug design and delivery, 1989
The electrostatic molecular potential (EMP) of model compounds (isoproterenol and four of its analogs) with agonist activity on the beta-adrenergic receptor was investigated, at the SCF-MO ab initio level. A method was developed to calculate the drug-receptor interaction energy (delta E) for these compounds, and the EMP and delta E values were compared

Dual Treatment of a Beta 3 Adrenergic Receptor Agonist and a Novel Estrogen Receptor Beta Agonist on Body Composition, Metabolism, and Glucose Tolerance in Obese Male Mice

Physiology
INTRODUCTION: Estrogen is protective against weight gain via mechanisms mediated by adipocyte-specific receptors. Specifically, estrogen receptor beta (ERb) activation is non-feminizing and increases adipocyte mitochondrial activity leading to increased energy expenditure (EE ...
