The present invention provides novel liposomes comprising Gd.DOTA.DSA (gadolinium (III) 2-4,7-bis-carboxymethyl-10-[(N,N-distearylamidomethyl-N′-amido-methyl]-1,4,7,10-tetra-azacyclododec-1-yl}-acetic acid), characterised in that said liposome further comprises a neutral, fully saturated phospholipid component (e.g. DSPC (1,2-distearoyl-sn-glycero-3-phospocholine]), which are of particular use in the preparation of magnetic resonance contrast agents for enhancing a magnetic resonance image of tumours in a mammal.
本发明提供了包含Gd.DOTA.DSA(钆(III)2-4,7-双羧甲基-10-[(N,N-二硬脂酰胺甲基-N′-酰胺甲基]-1,4,7,10-四氮杂环十二烷基}-乙酸)的新型脂质体,其特征在于所述脂质体进一步包含中性、完全饱和的磷脂成分(例如DSPC(1,2-二硬脂酰-sn-甘油-3-磷酰胆碱)),这些脂质体在制备用于增强哺乳动物体内肿瘤的磁共振成像对比剂方面具有特殊用途。
