摘要:
A novel class of mercapto acyl-carnitines is disclosed, wherein the mercapto acyl radical is the radical of saturated mercapto acids having from 2 to 10 carbon atoms. These mercapto acyl-carnitines are prepared, e.g., by first preparing the corresponding halogen acyl-carnitine and then substituting therein, by nucleophylic substitution, the --SH group for the halogen atom.These mercapto acyl-carnitines are useful therapeutic agents, e.g., for the treatment of intoxications and burns and as mucolytic agents. Dithio diacyl carnitines and hydrochloride salts thereof, which are intermediates, are also disclosed.

摘要:
A novel class of alkoxy-acyl carnitines, wherein the alkoxy-acyl radical has from 4 to 6 carbon atoms (tipically: methoxypropionyl, ethoxypropionyl and propoxyacetyl) is prepared by reacting a solution of a carnitine salt in an organic solvent with an alkoxy-acyl halogenide, thus obtaining the corresponding salt of alkoxy-acyl carnitine. By eluting an aqueous solution of this salt through a column of an ion exchange resin activated in Cl.sup.- or Br.sup.- form, the chloride or bromide of alkoxy-acyl carnitine is obtained. The alkoxy-acyl carnitines are therapeutically effective in the treatment of cardiac disorders, hyperlipidaemias and hyperlipoproteinaemias.

摘要:
A novel class of carnitine derivatives is disclosed which comprises thiocarnitine and the S-acyl thiocarnitines wherein the acyl radical is the radical of saturated organic acids having from 2 to 10 carbon atoms. The S-acyl thiocarnitines are prepared e.g. by reacting crotonoyl betaine halogenide with the corresponding thio-acid, while thiocarnitine is obtained by hydrolysis of an S-acyl thiocarnitine. These compounds are useful therapeutic agents, e.g. for the treatment of intoxications, liver malfunctions and burns.
