摘要:
A novel class of acyl-derivatives of carnitine is disclosed wherein the acyl radical is either the radical of unsaturated organic acids (typically, acrylic acid) or the radical of saturated organic acids substituted with tert-alkyl, cycloalkyl, cycloalkenyl, alkoxyl, heterocyclic and carboalkoxylradicals, or with aldehyde or hydroxy groups. These acyl-derivatives of carnitine are useful therapeutical agents in the treatment of cardiac disorders, hyperlipidaemias and hyperlipoproteinaemias.
摘要:
A chemotherapeutic composition for the control of plant diseases caused by mycoplasma-like organisms, rickettsia-like organisms, or seed-borne legume viruses. The composition is composed essentially of the tannate complex of picro ammonium formate combined with a minor amount of a surfactant sufficient to prevent formation of ammonium picrate. The preparation and use of the composition are disclosed. Also disclosed is a related chemotherapeutic composition for the control of plant diseases caused by plant pathogenic fungi and bacteria and composed essentially of a tannate complex of picro cupric ammonium formate in aqueous solution combined with a minor amount of a surfactant sufficient to prevent formation of ammonium picrate, along with its method of preparation and manner of use.

The process for the production of carnitine hydrochloride which involves placing an ester of .gamma.-halo-acetoacetic acid having the formula: ##STR1## wherein R.sub.1 is hydrogen, R.sub.2 is a lower alkyl group having 1 to 10 carbon atoms and X is a halogen atom selected from the group consisting of chlorine or bromine, in an aqueous solution of excess trimethyl amine held at a temperature between 0.degree. and 50.degree. C., a reaction resulting between said ester and said amine. The excess trimethyl amine is distilled off. The pH of the solution is adjusted between 4 and 8, (3-carbalkoxy-2-oxopropyl)-trimethyl ammonium halide resulting. The (3-carbalkoxy-2-oxopropyl)-trimethyl ammonium is hydrogenated without isolating said halide from solution, a carnitine ester resulting. The carnitine ester is converted by means of aqueous hydrochloric acid into carnitine hydrochloride.
