[ 1 ] - Novel cilostamide analogs, phosphodiesterase 3 inhibitors, produce positive inotropic but differential lusitropic and chronotropic effects on isolated rat atria
Objective(s): Recently, we showed that some new synthetic compounds structurally related to cilostamide (4-(1,2-dihydro-2-oxoquinolin-6-hydroxy)- N-cyclohexyl-N-methylbutanamide), a selective phosphodiesterase 3 (PDE3) inhibitor, produce inotropic effect comparable to that of IBMX (3-isobutyl-1-methylxanthine), a non-selective PDE inhibitor, but with differential chronotropic effect. In this in...
[ 2 ] - Combination of Nigella sativa with Glycyrrhiza glabra and Zingiber officinale augments their protective effects on doxorubicin-induced toxicity in h9c2 cells
Objective(s):The use of doxorubicin (DOX) is limited by its dose-dependent cardio toxicity in which reactive Oxygen Species (ROS) play an important role in the pathological process. The aim of this study was to evaluate the protective effect of three medicinal plants, Nigella sativa (N), Glycyrrhiza glabra (G) and Zingiber officinale (Z), and their combination (NGZ), against DOX-induced apoptos...
[ 3 ] - Differential Metabolic Effects of Novel Cilostamide Analogs, Methyl Carbostiryl Derivatives, on Mouse and Hyperglycemic Rat
Objective(s) PDE3 has a functional role in insulin secretion and action. We investigated the metabolic effects of new synthetic PDE3 inhibitors (mc1, mc2, mc5 and mc6), on mice and hyperglycemic rat. Materials and Methods The test compound or solvent was injected subcutaneously to mice, for 7 days. On day 8, blood and liver samples were obtained. In hyperglycemic rat, 0.5 g/kg glucose with o...
[ 4 ] - بررسی اثر عصاره آبی-الکلی گیاه کلپوره (Teucrium polium) بر ترشح انسولین از جزایر لانگرهانس جدا شده موش صحرایی
Background and Objective: Teucrium Polium (Labiatae) grows widespread in Iran and reduces blood sugar in-vivo. To examine the mechanism of this effect, in this study we explored the effects of aqueous-alcoholic extract of this plant on insulin secretion of isolated rat pancreatic islets. Materials and Methods: In this experimental study, the upper parts of the plant (stem, flowers and leaves) ...
[ 5 ] - Inotropic and Chronotropic Effects of 6-Hydroxy-4- Methylquinolin-2(1H)-One Derivatives in Isolated Rat Atria
Background: Selective phosphodiesterase (PDE3) inhibitors improve cardiac contractility and may use in congestive heart failure. However, their proarrhythmic potential is the most important side effect. Methods: In this research, we evaluated the potential cardiotonic activity of six new synthesized selective PDE3 inhibitors (6-hydroxy-4-methylquinolin-2(1H)-one derivatives) using the spontan...
[ 6 ] - Inotropic and chronotropic effects of new cilostamide derivatives on isolated rat atria
Introduction: It was shown in a previous study, that MCPIP, a cilostamide derivative, increased atrial contraction force without changing contraction rate. To improve this property, two new derivatives of cilostamide were synthesized and their effects on PDE3 activity and isolated rat atria contraction were investigated. Methods: The inhibitory effect of each compound on PDE3 enzyme was dete...
