The discontinuation of the substituent on the alpha carbon of the connecting chain by another oxygen atom (introduction of an ethoxyethoxymethyl group) has a positive effect on surface and infiltration anaesthesia. Of the prepared agents, 2-piperidino- and 2-(1-perhydroazepinyl-) derivatives with a hexyl or heptyloxy group in the o-position of the benzene ring were most effective; they exceeded the standards cocaine and procaine more than one hundred times. p-Derivatives were least effective; in some cases their indices of effectiveness did not achieve the effectiveness of the standards in both surface and infiltration anaesthesia under study.

TJ-23 (Toki-Shakuyaku-San) had little effect on either system. The protective effect of TJ-15 against lipid peroxidation could not be fully accounted for by its action on microsomal electron transfer, as evaluated by studying the kinetics of reduction of cytochrome C. In a free solution TJ-15 and TJ-23 effectively scavenged OH., radicals, as indicated by the inhibition of ethylene production from KMBA, and O2-. anion radicals, as assessed by the inhibitory effect on the rate of NBT reduction. The present results suggest that TJ-15, yet not TJ-23, is capable to reach hydrophobic intra-membrane sites at concentrations at which it is an effective antioxidant.
