[Molecular mechanisms of the action of local anesthetics].
Raman spectroscopy revealed a suppression of the polyene chain of C40-carotenoids in membrane of the frog nerve during local action of an anesthetic agent in resting and excitation. The phosphatidylcholine binding decreased during rhythmic excitation and local anesthetic action. A mechanism of potential-dependent changes of the carotenoid conformation during local anesthetic action, was discussed.
