The effect of mono- and bisdesmoside triterpene glycosides on the background activity of the grape snail Helix pomatia identified neurons was studied. Monodesmoside glycosides at concentrations of 10-3-10-4 M elicit stable hyperpolarization of neurons by increasing the membrane permeability for K+ ions. At concentrations of 10-5-10-7 M, they briefly change the neuronal impulse activity. The type of monodesmoside triterpene glycoside activity on neurons depends on the structure of the hydrocarbon. The glycoside effect on neuron membranes is related to the hemolytic activity 相似文献
