These chemicals are also called cholinergic drugs because acetylcholine (ACh) is the neurotransmitter used by the PSNS. Chemicals in this family can act either directly by stimulating the nicotinic or muscarinic receptors (thus mimicking acetylcholine), or indirectly by inhibiting cholinesterase, promoting acetylcholine release, or other mechanisms. Brenner, G. M. (2000). Pharmacology. Philadelphia, PA: W.B. Saunders Company. ISBN 0-7216-7757-6Beta-Bungarotoxin: β-Bungarotoxin is a form of bungarotoxin that is fairly common in Krait (Bungaros multicinctus) venoms.ChlorisondamineTrigonellineXimelagatranMuscarineMuscarinic antagonist: A muscarinic receptor antagonist (MRA) is a type of anticholinergic agent that blocks the activity of the muscarinic acetylcholine receptor. Acetylcholine (often abbreviated ACh) is a neurotransmitter, whose receptor is a protein found in synapses and other cell membranes.Concentration effect: In the study of inhaled anesthetics, the concentration effect is the increase in the rate that the Fa(alveolar concentration)/Fi(inspired concentration) ratio rises as the alveolar concentration of that gas is increased. In simple terms, the higher the concentration of gas administered, the faster the alveolar concentration of that gas approaches the inspired concentration.Cervical ganglia: The cervical ganglia are paravertebral ganglia of the sympathetic nervous system. These emerging postganglionic nerves synapse with preganglionic nerves from the thoracic spinal cord.TalipexolePD-0298029Patch clamp: The patch clamp technique is a laboratory technique in electrophysiology that allows the study of single or multiple ion channels in cells. The technique can be applied to a wide variety of cells, but is especially useful in the study of excitable cells such as neurons, cardiomyocytes, muscle fibers, and pancreatic beta cells.HSD2 neurons: HSD2 neurons are a small group of neurons in the brainstem which are uniquely sensitive to the mineralocorticosteroid hormone aldosterone, through expression of HSD11B2. They are located within the caudal medulla oblongata, in the nucleus of the solitary tract (NTS).Periodic current reversalPivagabineCalcium signaling: Calcium ions are important for cellular signalling, as once they enter the cytosol of the cytoplasm they exert allosteric regulatory effects on many enzymes and proteins. Calcium can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.Reversal potential: In a biological membrane, the reversal potential (also known as the Nernst potential) of an ion is the membrane potential at which there is no net (overall) flow of that particular ion from one side of the membrane to the other. In the case of post-synaptic neurons, the reversal potential is the membrane potential at which a given neurotransmitter causes no net current flow of ions through that neurotransmitter receptor's ion channel.N6-CyclopentyladenosineBeta1-adrenergic agonist: Beta1-adrenergic agonists, also known as Beta1-adrenergic receptor agonists, are a class of drugs that bind selectively to the beta-1 adrenergic receptor. As a result, they act more selectively upon the heart.NelotanserinAmthamineLong-acting beta-adrenoceptor agonist: Long-acting beta-adrenoceptor agonists (LABAs, more specifically β2-agonists) are usually prescribed for moderate to severe persistent asthma patients or patients with chronic obstructive pulmonary disease (COPD). They are designed to reduce the need for shorter-acting β2-agonists such as salbutamol, as they have a duration of action of approximately 12 hours in comparison with the 4- to 6-hour duration of salbutamol, making them candidates for sparing high doses of corticosteroids or treating nocturnal asthma and providing symptomatic improvement in patients with COPD.MivazerolPSN-375,963: PSN-375,963 is a selective ligand for the suggested novel cannabinoid receptor GPR119.SolabegronSC-17599SpiradolineTAN-67: TAN-67 (SB-205,607) is a opioid drug used in scientific research that acts as a potent and selective δ-opioid agonist,Fujii H, Kawai K, Kawamura K, Mizusuna A, Onoda Y, Murachi M, Tanaka T, Endoh T, Nagase H. Synthesis of optically active TAN-67, a highly selective delta opioid receptor agonist, and investigation of its pharmacological properties.Ligand (biochemistry): In biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. In protein-ligand binding, the ligand is usually a signal-triggering molecule binding to a site on a target protein.Crosstalk (biology): Biological crosstalk refers to instances in which one or more components of one signal transduction pathway affects another. This can be achieved through a number of ways with the most common form being crosstalk between proteins of signalling cascades.Adenosine receptor: The adenosine receptors (or P1 receptors) are a class of purinergic G protein-coupled receptors with adenosine as endogenous ligand.Opioid receptor: Opioid receptors are a group of inhibitory G protein-coupled receptors with opioids as ligands. The endogenous opioids are dynorphins, enkephalins, endorphins, endomorphins and nociceptin.Phenylpiperidine: Phenylpiperidine is a chemical compound with a phenyl moiety directly attached to piperidine. There are a variety of pharmacological effects associated some phenylpiperidines including morphine-like activity or other central nervous system effects.
