The present invention provides pharmaceutical compositions comprising lipophilic diesters of l,2-bis(2-aminophenoxy)ethane-N,N,N',N' -tetraacetic acid denoted herein as B APTA-DE, or salts thereof, in non-covalent association with a free amino acid, wherein a stoichiometric ratio of the free amino acid and the lipophilic diester in the composition is at least 3: 1, M denotes a hydrogen ion and/or a physiologically acceptable cation, and wherein R is selected from the group consisting of CnH2n+1 (n=1-10), CnH2n+1(OCH2CH2)m (n=1-20, m=1-6), (CnH2n+1)2N(CH2)m (n=1-6, m=1-6) and substituted or unsubstituted ArCH2; the substituents on the aromatic rings being in the ortho position. The invention further concerns use of said pharmaceutical compositions in the treatment of neurological conditions or diseases related to abnormal levels of divalent metal ions, said treatment resulting in minimizing the risk of developing undesired side effects associated with the therapeutic use of the lipophilic diester salts.
本发明提供了包含疏水性二酯化合物 l,2-双(2-氨基苯氧基)乙烷-N,N,N',N' -四乙酸(在此称为 B APTA-DE)或其盐的药物组合物,与游离氨基酸非共价结合,其中组合物中游离氨基酸和疏水性二酯之间的化学计量比至少为 3:1,M 代表氢离子和/或生理上可接受的阳离子,R 选自由 CnH2n+1(n=1-10)、CnH2n+1(OCH2CH2)m(n=1-20,m=1-6)、(CnH2n+1)2N(CH2)m(n=1-6,m=1-6)和取代或未取代的 ArCH2 组成的基团;芳香环上的取代基位于邻位。该发明还涉及上述药物组合物在治疗与二价金属离子异常水平相关的神经病症或疾病中的应用,该治疗有助于减少与疏水性二酯盐的治疗应用相关的不良副作用的风险。
