Analogs of Methyldopa 101 acetic acid with the diethylaminoethyl ester of this acid showed that the aralkylamino compound had a considerably reduced neurotropic activity. Other deviations are the length of the alkylene chain (here preferably more than three carbon atoms; in the substituted phenylacetic acid series preferably two or three carbon atoms) and the other acids which give high activity.The 3,4,5-trimethoxybenzoate of /3-diethylaminoeth-anol is, for instance, much less active than the corresponding diphenylacetate ester.The phenethylamine derivatives with a small substituent, e.g., a hydrogen atom or a methyl group at the nitrogen atom (53, 54) possess considerable adrenolytic activity. Especially piperidine (10-12) and p-hydroxyphenylisopropylamine derivatives (18, 19, and 25) are fairly active.
