Abstract
L-aminoacyl derivatives of L-carnitine of general formula (I) ##STR1## wherein R is an alkyl radical selected from 1-methyl-propyl, isobutyl, isopropyl, mercaptomethyl and 3-guanidino propyl, and their pharmacologically acceptable salts, are prepared e.g. by reacting a solution in an organic solvent of L-carnitine whose carboxyl group is protected with an N-protected aminoacid in the presence of a condensing agent and then removing the amino-acid and carnitine protecting groups, thus obtaining the desired compound.
