The present invention is predicated on the realisation that problems with the poor water solubility of arsenic trioxide and the extreme difficulty in dissolving arsenic trioxide in anything other than a very basic solution, could be overcome by forming a much more soluble diarsenic tetraoxide, including the compound NaHAs2O4, prior to its delivery to a patient. Pharmaceutical compositions with such compounds and their use in the treatment of cancers is disclosed.
本发明是基于这样一种认识,即
三氧化二砷的
水溶性很差,除了非常基本的溶液之外,
三氧化二砷极难溶解于其他任何溶液中,而在将其提供给病人之前,可以通过形成溶解性更高的
二胂四
氧化物(包括化合物 NaHAs2O4)来克服这一问题。含有这种化合物的药物组合物及其在治疗癌症中的用途已被公开。
