(12.000 rpm) y las muestras se midieron inmediatamente por HPLC. La evaluación de la solubilidad se efectuó a través de una calibración de la N,N'-bis(succiniloxi)pentamidina (1) en DMSO. El compuesto es bien soluble (7,5 mM) a un valor del pH fisiológico de 7,4. La solubilidad se mejoró ulteriormente cuando se aumentó el valor del pH (véase la Tabla 1).
Como comparación se investigaron otros diferentes profármacos de pentamidina, con el fin de poder evaluar mejor la solubilidad en comparación con los derivados ya descritos. La determinación de las solubilidades se llevó a cabo análogamente al método descrito para el compuesto 1.

Determinación de la fijación a proteínas de la N,N'-bis(succiniloxi)pentamidina (1)
La determinación de la fijación a proteínas del plasma se llevó a cabo en tres concentraciones diferentes (10, 20 y 50 µM). Como soluciones de proteínas se utilizó una solución de albúmina al 4 %. Se pipetearon en cada caso 50 µl de una solución de la sustancia concentrada a 10 veces en 450 µl de la solución de proteína. La incubación se efectuó durante 15 min en un baño agitado de agua a 37°C. A continuación, las muestras fueron transferidas a unas unidades de ultrafiltración (Vivaspin 500, límite de exclusión 10 kDa) y se centrifugaron durante 15 min a 10.000 rpm. El material filtrado se analizó por HPLC. Adicionalmente, para cada concentración se llevó a cabo un control, que no había sido mezclado con proteínas y no había sido centrifugado. Otro control adicional sin adición de proteínas, que sin embargo había sido separado por centrifugación a través de la unidad de filtración, sirvió para la validación de la metodología.
El análisis de la muestra determinó una fijación a proteínas de 97,1 ± 1,2 % para el compuesto 1.
Investigación de la bioactivación de la N,N'-bis(succiniloxi)pentamidina (1)
Determinación de la activación de los profármaco con diferentes sistemas de enzimas subcelulares
La activación del profármaco se determinó in vitro mediante unos preparados enzimáticos subcelulares. Como preparados enzimáticos se utilizaron unos materiales sobrenadantes de 9.000xg, microsomas y mitocondrios de tejidos de hígados y riñones porcinos. Las tandas de incubación se componían de un profármaco 500 µM, NaDH 1 mM, 1 U de una esterasa y 0,3 mg de un preparado enzimático, disueltos en 250 µl de tampón fosfato 100 mM de pH 6,3. La incubación se efectuó durante 20 min a 37 °C en un baño de agua agitado. La incubación se finalizó mediante la adición de 150 µl de metanol. A continuación, las muestras se agitaron durante 10 min y la proteína precipitada se separó por centrifugación a 10.000 rpm durante 15 min. El material sobrenadante se midió con ayuda de la HPLC. Las tasas de conversión química determinadas se exponen en la Tabla 2.
