Guinea pigs (males weighing 200-400 g) were scored by a blow on the head and was driven away. Length removed the small intestine is approximately 2 cm from ileo-ceilinga valve. A piece of the colon stretches over a glass rod and carefully remove mesentery. A layer of longitudinal muscles are separated and removed from the underlying layer of circular muscles tangential motion away from mesenteric connection (i.e. from the mesentery). Plots of the longitudinal muscles of 4-5 cm in length placed in a 10 ml bath for bodies containing Tyrode solution at 37oand rinsed with 5% carbon dioxide in oxygen. The Tyrode solution contains the following substances concentration, mol/l: NaCl 137,0; CaCl21,8; KCl 2.7; The MgCl 1,05; NaHCO311,9; NaHPO4of 0.4; glucose 5,6; and methysergide of 0.1 M. the Sections of intestine were maintained under constant tension efforts to 500 mg. Reduction was recorded using isotonic swinging arm. After equilibration for 30 min was applied specified concentration carbachol in 10-minute intervals until it reached a constant reaction.Obtaining a curve of concentration and reaction.Curve response to non-cumulative concentration for 5-HT stipulated in the previous experiments have shown, these intervals were long enough to avoid tachyphylaxis. Each concentration left in contact with the tissue for 1 min Every part of the intestine is used only once to record two curves of reaction on concentration: the first for only one 5-HT, and the second for 5-HT in the presence of prescribed concentration of antagonist, and each plot served as thus your own control. Antagonists allow pre-balanced for at least 10 min before addition of 5-HT. The concentration, expressed in percent of the maximal response to 5-HT, which were obtained from several drugs celebrated as the average values to obtain the logarithmic curves of reaction from concentration. The inhibition constants expressed as values pA2that determine graphically by conventional methods (Arunlakshana and other 159, McRay, 1978).In this experiment, 5-HT exerts dependent on the concentration contractile action. 5-HT causes this is the basic contractile activity in muscle longitudinal muscle area of the colon of the Guinea pig by the release of substance P from nerve endings in the tissue. This action passes on the release of substance P. Released substance P activates neural receptors substance P, and this causes the release of acetylcholine, which then activates muscarinic receptors, located on the smooth muscle cells, and causes them to fall. At higher concentrations of 5-HT activates the second neural receptor, which leads to the release of substance P to activate receptors substance P in the cells of smooth muscles, crying out at the same time.Compounds according to the invention is mainly act on the blocking receptors high affinity to 5-HT4by inhibiting this caused by 5-HT reduction, for example, at concentrations of approximately 10-8up to 10-6mol/L. These compounds exhibit less antagonistic activity to the receptor sites of low affinity to 5-HT3.Compounds according to the invention are therefore useful for the treatment of motility disorders of the gastrointestinal tract, such as tachygastria, difficulties with evacuation of the stomach due to tachygastria syndrome acute abdomen, intestinal spasms, cramps, constipation due to increased tone of the colon, disease, gastro-esophageal reflex and dyskinesia of the biliary system.
