The preparation and use of a protected organic aldehyde is described wherein bioavailability of the orally administered therapeutic aldehyde is improved. The protected aldehyde is prepared by reacting the aldehyde with a protecting group, for example, condensing the aldehyde chemically with a thiazolidine-4-carboxylic acid. The improved bioavailability of such orally administered drugs increases the feasibility of delivering sufficient amounts of vanillin or other therapeutic organic aldehydes in vivo to prevent sickling in sickle cell anemia. Combination therapy is also described wherein a protected organic aldehyde is administered to a subject in treatment of sickle cell anemia in conjunction with one or more other drugs, such as pain killers, used in treatment of the symptoms of sickle cell anemia or sickle cell disease.
本文描述了一种保护有机醛的制备和使用方法,从而提高口服治疗醛类药物的生物利用度。保护醛类化合物是通过将醛类化合物与保护基反应制备而成,例如,化学上将醛类化合物与噻唑烷-4-羧酸缩合。这种口服给药药物的生物利用度提高,增加了在体内传递足够量的香草醛或其他治疗性有机醛类化合物以预防镰状细胞贫血的可行性。本文还描述了联合治疗方法,其中在治疗镰状细胞贫血的患者中,将保护有机醛类化合物与一种或多种其他药物(如止痛药)联合使用以治疗镰状细胞贫血或镰状细胞病的症状。
