introduction: although tolerance to and dependence on opioids are characterized by excessive activity of camp pathway in some brain stem nuclei, the impact of morphine dependence on activity of camp pathway in paragigantocellularis nucleus (pgi), located in the rostral ventrolateral medulla, remains unclear. therefore, the effect of adenyl cyclase activator forskolin on spontaneous firing rate ...

The interaction of forskolin with adenylate cyclase was studied by evaluating its effect on metal and metalATP kinetics and by measuring its protective effect when the enzyme was subjected to denaturation conditions. The solubilized calmodulinand forskolin-sensitive adenylate cyclase from brain and the particulate enzyme from platelets were inactivated upon preincubation with N-ethylmaleimide. ...

Forskolin is a diterpene derived from the plant Coleus forskohlii. Forskolin activates adenylate cyclase, which increases intracellular cAMP levels. The antioxidant and antiinflammatory action of forskolin is due to inhibition of macrophage activation with a subsequent reduction in thromboxane B2 and superoxide levels. These characteristics have made forskolin an effective medication for heart ...

Forskolin activated adenylate cyclase of purified rat adipocyte membranes in the absence of exogenous guanine nucleotides. Guanyl-5”yl imidodiphosphate (Gpp(NH)p) inhibited the forskolin-activated cyclase immediately upon addition of the nucleotide at concentrations too low to activate adenylate cyclase (lo-’ to M). Inhibition seen with a very high concentration of Gpp(NH)p M) lasted for 3-4 m...

Brefeldin A (BFA) causes rapid redistribution of Golgi proteins into the ER, leaving no definable Golgi apparatus, and blocks transport of proteins into post-Golgi compartments in the cell. In this study we follow the disassembly of the Golgi apparatus in BFA-treated, living cells labeled with NBD-ceramide and demonstrate that forskolin can both inhibit and reverse this process. Long, tubular p...

The present study aimed to investigate the effect of forskolin on retinal inflammation under diabetic conditions. C57BL/6 mice were randomly divided into normal control, diabetic control and forskolin treatment groups. The diabetic model was established by intraperitoneal injection of streptozotocin. The forskolin treatment group received intragastrical administration of forskolin for 12 weeks,...

We have used wild type 549 lymphoma cells and S49 variants that have lesions in their ability to generate CAMP to explore the mechanism of activation of adenylate cyclase by the diterpene forskolin. In intact wild type cells, forskolin rapidly and reversibly stimulated CAMP accumulation several hundred-fold over basal levels. Simultaneous addition of forskolin and the padrenergic agonist isopro...

Objectives: The presence of additional cis-variants in a patient’s CFTR genotype may reduce the total amount protein or alter its 3D structure, and therefore administration targeted therapy to patients with complex alleles be challenge. Methods: study included 5 F508del/[L467F;F508del] one patient CFTRdele2,3/[S466X;R1070Q] genotype. Residual function channel effectiveness modulators were evalu...

The effect of the adenylate cyclase activator forskolin on bone resorption and cyclic AMP accumulation was studied in an organ-culture system by using calvarial bones from 6-7-day-old mice. Forskolin caused a rapid and fully reversible increase of cyclic AMP, which was maximal after 20-30 min. The phosphodiesterase inhibitor rolipram (30 mumol/l), enhanced the cyclic AMP response to forskolin (...

Intra Ocular Pressure (IOP) is the fluid pressure inside the eye and is the most important risk factor for glaucoma. From the roots of Coleus forskohlii, an aromatic herb growing all over India, we extracted Forskolin. In this study we studied the IOP lowering activity of two strengths of Ocufors, viz., Ocufors (Forskolin 1% w/v ophthalmic solution) and Ocufors (Forskolin 0.15% w/v ophthalmic s...
