Abstract

LA PRESENTE INVENCION SE REFIERE A COMPOSICIONES LIPOSOMATICAS QUE TIENEN UN GRADIENTE DE CONCENTRACION QUE CARGA AMINO ACIDOS Y PEPTIDOS QUE MUESTRAN CARACTERISTICAS ACIDAS O BASICAS DEBILES EN LIPOSOMAS. ESPECIFICAMENTE CARGADAS EN LAS LIPOSOMAS POR LOS METODOS DE LA PRESENTE INVENCION, SON AMINO ACIDOS O PEPTIDOS CON EL TERMINAL C SUSTITUIDO. LAS LIPOSOMAS SON CON PREFERENCIA GRANDES VESICULAS UNILAMINARES. EL GRADIENTE DE CONCENTRACION ESTA FORMADO POR ENCAPSULADO DE UN PRIMER MEDIO EN LAS LIPOSOMAS, TENIENDO DICHO MEDIO UNA PRIMERA CONCENTRACION DE UNA O MAS ESPECIES CARGADAS Y SUSPENDIENDO LAS LIPOSOMAS EN UN SEGUNDO MEDIO QUE TIENE UNA SEGUNDA CONCENTRACION DE UNA O MAS ESPECIES CARGADAS, TAL COMO, POR EJEMPLO, UN GRADIENTE PH. TAMBIEN SE DESCRIBEN PREPARACIONES FARMACEUTICAS QUE COMPRENDEN TALES AMINO ACIDOS O PEPTIDOS CON EL TERMINAL C SUSTITUIDO, LOS CUALES HAN SIDO CARGADOS EN LAS LIPOSOMAS POR EL METODO DE LA INVENCION.
