Abstract: Una prodroga que comprende un anfifilo fluorado, composicion que comprende la prodroga, y métodos para usar la prodroga y la composicion. La prodroga quecomprende un anfifilo fluorado, caractericada porque consiste de un compuesto de formula:R-(X)p-D; en la cual R es una mitad anfifílica fluorada; X es ungrupo ligante; p es un entero de 0 o 1; y D es un agente bioactivo. Los compuestos de la presente ofrecen un índice terapéutico mejorado y unacapacidad de activacion ya sea por hidrolisis in situ de uniones lábiles, por mediacion de ultrasonido, o por otras liberaciones mediadas por energía, talescomo microondas, radiofrecuencia o hipotermia de induccion magnética, fotoactivacion dirigida por laser, hipertermia o ablacion. La prodroga tambiénprovee liberacion específica en un sitio y direccionamiento para mejorar la eficacia y disminuir la toxicidad del agente bioactivo. Mitad anfifílica oanfífileo se refiere a un compuesto sintético,semisintético(natural modificado) o natural que tiene una parte hidrofila, soluble en agua y una parte hidrofoba,insoluble en agua. Los compuestos anfifílicos preferidos están caracterizados por grupo cabeza polar, por ejemplo,un grupo fosfotidilcolina, y una o máscadenasalifáticas, no polares, por ejemplo, grupos palmitoilo. La mitad anfifílica fluorada se refiere a un compuesto anfifílico en donde por lo menosun átomo hidrogeno del compuesto anfifílico es reemplazado por un átomo de fluor.

Abstract: Gas filled liposomes prepared by a vacuum drying gas instillation method and/or gas filled liposomes substantially devoid of liquid in the interior thereof, are presented as novel potentiators for ultrasonic hyperthermia. The liposomes of the present invention, which may be administered into the vasculature, interstitially or into any body cavity are designed to accumulate in cancerous and diseased tissues. When therapeutic ultrasonic energy is applied to the diseased region heating is increased because of the greater effectiveness of sound energy absorption caused by these agents.

Abstract: A method and apparatus for making vesicles suitable for use as contrast agents in which a container containing an aqueous suspension phase and a separate gas phase is shaken using reciprocating motion. The reciprocating motion is produced by a shaker arm that moves the container in two, substantially perpendicular directions, with the motion in the first direction being along an arcuate path. The overall path of the motion occurs in a figure-8 eight pattern. The frequency of shaking is at least approximately 2800 RPM, the length of the shaker arm is at least approximately 6 cm, and the angle through which the shaker arm rotates in the first direction is at least approximately 3 DEG . The total length of travel around the figure-8 pattern is at least 0.7 cm.
