Abstract
EL INVENTO SE REFIERE A UN PROCEDIMIENTO PARA SEPARAR FOLINATOS (6R, 6S) EN SUS DIASTEROISOMEROS QUE CONSISTE EN: MEZCLAR UNA SOLUCION DE UNAS SALES DEL ACIDO (6R, 6S) FONILICO CON UNAS SALES SOLUBLES EN AGUA ALCONOTERREAS, AMONICAS O ALCALINAS DE UN ACIDO ORGANICO O INORGANICO, PARA FORMAR UNA SUSPENSION; FILTRAR LA SUSPENSION PARA RECOGER COMO PRECIPITADO LA SAL DE FOLINATO (6S) Y UN LIQUIDO DE FILTRACION QUE SE MEZCLA CON DISOLVENTES ORGANICOS MISCIBLES CON AGUA Y/O SALES ALCALINOTERREAS SOLUBLES EN AGUA PARA PRECIPITAR FOLINATO (6S) Y FORMAR UNA SUSPENSION; FILTRAR LA SUSPENSION PARA RECOGER UN PRECIPITADO Y CRISTALIZAR EL PRECIPITADO LIBRE DE FOLINATO (6R). LA SEPARACION DEL ACIDO FOLINICO (6R) DE SALES ALCALINOTERREAS SE REALIZAN NEUTRALIZANDO LA SOLUCION. EL FOLINATO (6S) OBTENIDO SE UTILIZA COMO MEDICAMENTO PARA EL TRATAMIENTO DE ANEMIAS MEGALOBLASTICA (CARENCIA DE ACIDO FOLICO) COMO ANTIDOTO PARA REFORZAR LA TOLERABILIDAD DE ANTAGONISTAS DE ACIDO FOLICO COM AMINOTERREA, METOHEXATO Y 5-FLUORARACIL EN LA TERAPIA DEL CANCER Y TRATAMIENTO DE ENFERMEDADES AUTOINMUNES COMO ARTRITIR REUMATICA, Y PSORIASIS Y REFORZAR LOS ANTIPARASITARIOS. SE EMPLEAN SALES MAGNESICAS, CALCICAS O SODICAS COMO SALES ALCALINOTERREAS, ALCALINA DEL ACIDO FOLICO (6R,S), SE UTILIZAN HALOGENOS SODICOS, POTASICOS O AMONICOS COMO SALES AMONICAS O ALCALINAS DE ACIDOS INORGANICOS; SE EMPLEAN ALCOHOLES O CETONAS DE BAJO PESO MOLECULAR COMO DISOLVENTE ORGANICOS PARA SEPARAR EL FRENATOR (6S) Y SE UTILIZAN SALES CALCALINOTERREAS SOLUBLES EN AGUA (HALOGENUROS DE CALCIO).
